Michelle Honda is the name of the flight attendant who was at Row 15. She actually crawled through the section that blew off to get to the other attendant who was severely injured. And did her best to help the passengers- simply AMAZING.
I was on a flight recently where the pilot informed us that a bird strike had occurred on the previous flight. He said that they were going to delay the flight till they were certified to take off by an inspection team. The guys sitting in front of me started complaining about it, saying they were wasting time, but I was grateful that they cared enough about keeping the aircraft operational and safe.
I had a similar situation. We were getting ready to push back from the gate when the captain said that there had been a bird strike near the tail on the previous flight which left a small dent that had to be measured. I don't know what the specs were but aviation enthusiasts would know, it couldn't exceed a certain width, length, and depth. He even told us what it was at the time. He was very transparent about what was happening, which put everyone at ease because we weren't just sitting there nervously watching maintenance people outside the aircraft with no idea what was going on. Everyone relaxed and took it in stride, knowing this meant the dimple would either be out of range and we would deplane and switch aircraft or it would be within tolerance and we'd take off. Everyone was actually pretty cheerful. I didn't hear any complaints. In fact, all around me people were laughing & saying "better safe than sorry," and joking about the condition of the bird. It turned out not to be serious enough to ground the plane and we took off. But the key was the captain's transparency. It was only because he was completely honest with us and detailed about what was going on that nobody was concerned about the delay.
Clarabelle "CB" Lansing had more than 30 years of experience as a flight attendant and is really heartbreaking that they never found her body. May she rest in peace
One of the reasons I never fly Boeing if possible they are still building planes that you have to trust not to fall apart in flight just look at their new junk 737 Nax
CB began her career BEFORE Jet Airliners! 37 years experience on this day. CB was the GOAT! Flight Crews deserve Respect, but are often taken for granted by Passengers. RIP CB! ❤🫶
I was an RN working at the hospital a mile from the airport on Maui when this happened. It was my day off, but I got a call from the hospital saying there was a level 3 disaster and asking me to come in. I knew not to waste time asking what it was. I hung up and headed in. On the way, I passed the airport and sitting on the tarmac was a plane that looked like it had been opened up with a can opener. The hospital was packed with all the passengers being triaged by what looked to be every single healthcare provider on the island. Most of the passengers had cuts and eye irritations. Five were more serious. I heard stories of passengers in the aisle seats holding onto those buckled into the window seats where there was no wall. I understand the phenomenon of not really seeing something critically that has never occurred before, even with the bulletins. That is the problem with unprecedented occurrences. That it happened first (and probably last) in our heavily salty air with very high cycles, is not surprising either. I used to windsurf on a beach right next to the airport. After the accident, we could turn around and see that torn apart aircraft sitting there for weeks. Very sad, but a fantastic job by the crew, first responders, and the hospital.
I can't imagine the chaos in that ER. It must have been busy already (the ER always is), and then 150 passengers crowding in there all at once must have been overwhelming. Good for you for just dropping everything to go and help these people, to try and ease the tension on the hospital
Thank you for your dedicated service to the medical industry ❤ I can’t imagine the horror of seeing that shredded aircraft on your way to the hospital that day. Horrible.
My biggest takeaway was the crew member that was crawling up and down the aisles trying to reassure the passengers that everything would be okay. She deserves some kind of medal for bravery
The whole crew sounds like they deserve awards. The pilots appear to have done pretty nearly flawlessly under the circumstances, circumstances they couldn't have really trained for, not entirely.
Your 2 co-pilots look so calm and serene, snoozing on the couch, even while you describe such a stressful situation. I'd trust them to get me out of any jam. 😌
This sounds silly, but one of the things I really like about this channel is the conversation aspect of it. The periodic stumbling over words, gathering thoughts and er/ums make it so much easier to listen to because it’s like we’re just sitting down with coffee talking about the accident. The video is not over edited to “perfection” and I actually like that a lot. Keep it up!
@@SasquachPL I think at one point when he was explaining the glue he said, "You with me still ?" I wasn't but kept watching and listening. Love the way he explains everything and I can usually follow and understand it all but some of the really technical stuff I'd have to watch two or three times before it sunk in if it was important enough for me to do so. It isn't. I'll let the investigators sort this stuff out.
Very true. Natural conversation. I love that about people who show that they are actually pausing to think. Which means they're doing this completely authentically as opposed to the fakery of Mainstream Media and Co. where it feels like we're just the guinea pigs for alreadyprepared propaganda programs in a simulation.
I imagined they were dreaming while listening to the story subconsciously. Can you imagine being a dog, hearing and only understanding maybe 15% of the story and dreaming about chewing on a cable? Suddenly you wake up and think its your fault the plane crashed. I know its absurd. I mean, I'm a human and awake and I only understood maybe 30% of the story.
Mentor Pilot: "I want you to remember that flying is very safe....OK, now imagine being in a plane where the roof gets RIPPED OFF!!!" In all seriousness though, you really are doing aviation a great service. I hope you get officially recognized for it some day. Keep up the great work.
Being a trained accident investigator myself (but for trains) I find these videos really well made. Much more factual and less "sensational" then commercially produced "Air Crash Investigations" type TV shows. Keep up the good work!
I'm very sad that she passed away. Speaking of that flight attendant, when I watched the Air Crash Investigation episode for this particular incident, apparently there is an alternative theory call Fluid Hammer, which is when a fluid object hits a small area, it creates a hammer effect that creates tremendous force; it is similar to how when you drop a plug into a sink or bathtub, you will notice a sudden increase in suction as it gets very close to the mouth of the drain. According to the engineer, he hypothesizes that it was possible that the plane in fact tore as designed, but the flight attendant what sucked into the hole. But as the tear strips are smaller than her frame, it created the same effect, and essentially created a pressure spike, which caused the rest of the weakened frame to cascade fail until there was insufficient force and metal fatigue for the tear to continue. To my understanding, the FAA rejected the conclusion, but did state the concept deserved further study. But it also makes me cringe because that meant her death was far more brutal than what's suggested by this report. With that in mind, I hope her death was instant, which I suppose is better then simply being sucked out and falling while conscious.
@@TheEDFLegacy Unfortunately, there is basically not such thing as an "instant" death. All we can hope is that she did not have time to understand what was happening.
@@DrewNorthup Typically, the concept of "instant death" involves a level of trauma that I dare not wish to describe here. In other words, brain function is instantly silenced. That being said, this may not have happened here, and I hope she passed out extremely quickly.
They believe CB Lancing was blown through the hole that appeared and got stuck, causing the Fluid Hammer Effect, causing the rest of the damage. ( Fill your bath and take the plug out, then replace it, you will notice there is a shock and the plug gets pushed back down.)
I’m a fuselage structure mechanic with 15 years experience, and I’m damn impressed with how concisely you explained the basics of the design to illustrate how the lap join cracking developed and caused the failure. Well done sir.
Mentour, my uncle Don Carlsmith, was on this flight seated in first class. Flight attendant Lansing had just given him a cup of pineapple juice when she was sucked out of the plane. My uncle suffered lacerations to his head and shoulders from the flying debris. Amazing job of the pilots to get the plane on the ground and land safely. Thanks for this really informative video.
She had served so many cups of pineapple juice with a smile that God lost his patience and could no longer tolerate her not being with Him. Then he noticed the perfect setup to kill one bird and a foolish management with one stone.
@@MrSmellymonkeyman Take that grievance up with God. We have been given free will, so we can choose how to look at things, including spreading doom and gloom on top of the inevitable nature of death like you do.
As an engineer, people always accuse me of over complicating things. I think ahead and I want to make sure I don't make things that break. Watching these videos gives me so much insight on how to think ahead better. I'm not into aviation, just a lowly computer and communication engineer, but these videos are a goldmine. I can't imagine how pilots can keep a straight mind going into a cockpit.
My fathers friend was a passenger on that flight, when the decompression happened, he had all of the oxygen sucked out of his lungs and had great difficulty starting to breathe again. He said it was absolutely terrifying and thought he was going to die. As they were landing he realised his shoes had been sucked off his feet and were gone.
I worked with a guy who was on that flight. In normal conversation at work, he was always the type to throw in a joke or two. But when this flight came up, I've never seen anyone so serious in my life.
is that how sudden decompression works? i always thought you dont notice it and you slowly become essentially drunk and then pass out by lack of oxygen, i was not aware you can have air sucked out of your lungs, i just don't think it works like that but I don't know so thats why im asking, if anyone knows.
@@Auron710 In the past I was driving motorbikes. That is ok as long as the speed stays under 160 km/h. When you go faster till 195 km/h, it feels like the wind is trying to rip off your helmet with a force equal to a bucket of water of 10L, equaling 10 kg. I did not experience faster speeds on a bike, but went on in windturbine design. There is a lot of power in air and wind, which is air in motion, but also in vacuum, which is the lack of air. Nice things to play with in windpower design…

Sounds awful, but I kind of hope she was struck in the head, snapped her neck, or something in the process of being ejected and basically killed instantly or lost conciousness.
@@barbarachambers7974I think you're right. She was sucked up and smashed against the ceiling and likely killed instantly. Still sad but at least she didn't suffer
My family and I flew on this aircraft (N73711) from Honolulu to Kauai then to the Big Island about 4 weeks before this accident. We were meant to go direct from Honolulu to Hilo but we got on the wrong plane and ended up doing a detour through Kauai. I remember this aircraft vibrating a lot and making all sorts of strange noises, felt like it was held together with chewing gum. I have a photo of me taken on board with a look of concern on my face. The flight attendant told me 'This plane always rattles." I'm now a Aircraft Maintenance Engineer (A&P) for a airline and have never been on a aircraft like that since that scared the hell outta me more than this one did.
@@Flarptube The aircraft involved was the 152nd Boeing 737 airframe. It was built in 1969 and delivered to Aloha Airlines as a new aircraft. Its registration was N73711[4] and it was named Queen Liliuokalani after Lili'uokalani.
"I remember this aircraft vibrating a lot and making all sorts of strange noises..." All Boeings do that. They're incredibly poorly built aircraft compared to Airbus.
@@Flarptube 737-200s were designed to hold on 60 000 cycles, this one had 90 000. I can think about the female passenger that remarked the crack on the left side of this aircraft when boarding. She didn't tell anything to anybody because she thought "Oh, I guess everyone knows that at the company". I would hate to be in her shoes, even after all these years.
So impressive how everyone kept their cool and kept working all the way through. I saw interviews with some of the passengers and they were doing everything they could to support each other too.
I have read that one passenger, who was interviewed after the incident, actually noticed tears between the rivets, just to the right of the entry door, as they boarded the aircraft. She mentioned the issue to her traveling companion but not to the crew. In addition, this particular aircraft, and others owned by the airline, underwent far more 'pressurization cycles' compared to the expected 'average'. This was due to the 'short hop' operation in the Hawaiian Islands. Far more 'take offs', 'landings', 'pressurization' and 'de-pressurizations' than 'average' for hours of flight time. Amazing only one was killed. God Bless her and her family.
I had been on Delta 1989 in US. Birmingham Al. I never heard the outcome. Another one in 1996 when we deplaned due to a bomb scare. Turned out it was no bomb but a fool playing with fire. He sprayed hairspray from a can and lit a match. They arrested him but we had to wait 2 hours in Phoenix to continue on to Las Vegas. Meanwhile I'm not afraid to fly. I still go to Vegas CA TX DFW Hawaii and Florida to Minnesota. My family is spread all over and I stayed on a train for 4 days to get from east coast to west coast. It was scenic deer and moose birds snow waterfalls but if you're in a hurry 4 to 5 hours and you arrive in Calif.
I heard about that, too! It's so important for passengers to tell the crew of any abnormalities they notice. Hell even if it's something completely normal that they mistake for being odd, you're still better off telling the crew.
I have worked for a MRO responsible of the cabins' refurbishment as an engineer specialized in structural components. Most of my job was to perform decompression analysis, as the new cabin included implementation of new seats for example. These decompression analysis are mandatory to allow an aircraft to go back to flying, because the biggest risk is a decompression like in this accident: loss of part of the floor that contains some of the cables that operate the flight controls. The most critical load case is an opening in cabin (door or portholes opening...) while the cargo bay is completely empty. indeed, the volumes of air in the cargo is huge without any cargo in it, but at the beginning of the event only the air in the cabin can exit. Therefore, there is a period (few seconds) where the cargo is full of air while the cabin is empty. This results in a very high load applied on the floor from the bottom to top which could lead to a floor breakout. This is why since this accident we have seen emerging new device appear to regulate pressure between cabin and cargo called Dado panel (Airbus) / Return Air Grid (Boeing). Those are basically opening that allow the air to pass from the cabin to the floor (along the shear truss at the floor) to the cheaks sections in the cargo, finally reaching to cargo as the straps in the cheek break because of pressure (obviously working from cargo to cabin depending on the blow-out location). Most of the engineering work consists in the analysis of the obstruction of those dado panels to determine whether the floor could sustain the load of a decompression. indeed, these panel are partially covered by the seats (mainly business seats), and therefore reduce the amount of air that can go from cabin to cargo. Sorry for this big (and boring) cobblestone, but I figured it might interest a few people, since we were perfectly in the theme :-)
I'm curious why a hole above the floor worse than one below in the cargo compartment? As I'm sure you know, airplanes have been lost due to cargo area decompression. Also, don't most passenger aircraft have substantially more air volume above the floor than below it? Wouldn't this larger volume control the minimum through-floor venting required?
Problems have occurred where dado panels were not fitted and the decompression event occurred first in the cargo hold. Partial collapse of the floor area jammed flight control cables, which typically run under the floor , caused loss of control to tail flight surfaces .
After listening to the video about the pilot who allowed his kids to fly, the pilots who wanted to join the 41k club (I think it was 41k) and the ones who hit the water twice it was good to hear a video where the pilots didn't cause the accident
I am a very nervous flyer, but this video actually made me feel better, that so many things went wrong and they still landed the plane with only one casualty.
As long as flight controls and aerodynamics that is left, allow pilots to get to the ground in controlled fashion, any visually horrifying structural damage is just.. visually horrifying. For instance damaged elevator or fixed in some extreme position with aircraft looking pristine, would likely be fatal. Luckily there is some redundancy in systems in aircraft and airliners have great gliding capability (much better than your 4-seat Cessnas), so even loss of all engines is almost "standard procedure" for good pilot if happens at safely high altitude.
since I started working in teh aviation industry its made me realize how many things go wrong that the passenger has no idea about! A few weeks ago one of our aircrafts had 16(!!) seagulls go through the engine and everybody was fine afterwards. Went back to base and there were just some fanblades that had to get switched out.
Wow, that cabin crew member who crawled up and down the isle to comfort passengers is incredible. In accidents like these I'm always in awe at how much dedication the crew has to all on board.
And how cost cutting management is shitting on those people, removing every reason to be that dedicated and loyal. People like the current SAS management belong in padded cells with drugs that stop them giving out orders.
I’m trying to process that as a passenger and I can’t imagine NOT trying to throw her in a seat and strap her down - or create a leash for her, or something. The terror of “will I watch her die” on top of everything else…
@@khills If I was in an aisle seat, I would have insisted on pushing her down with a foot/hand until the end of the flight, if I was in the mental state to care about that.
Yet ANOTHER *combination of factors* leading to disaster. Engineering + construction + maintenance shortcomings. This would never have happened in the UK or US aviation industry in the 50s, 60s. Safety, quality, reliability as legacies from WWII military mindsets and specifications.
@@mikeyearout7234 So what. Certain maintenance checks and procedures were supposed to be done in the 70s, 80s to prevent the roof flying off. And besides, not all, nor even one other identical model has lost its roof. So there goes your argument that age was particularly responsible. The investigaton clearly showed glue failure, *unchecked and unaddressed* material fatigue, despite a manufacturer bulletin.
Had to study this failure in one of my mechanical engineering classes. Also, Boeing wasn't considering high cycle flights in their bulletin to require more in-depth inspections. Aloha was unique in were Boeing often thought in hours of flight time to do more invasive and rigorous inspections, this was a classic cyclic fatigue in a moist and salty environment which should have required more frequent and rigorous inspections because of pressurization cycles (impacted by the number of flights), not vibration cycles (which are more flight-time dependent).
@Playford Seven Fatigue in the fuselage structure is more dependent on flight cycles. That is, the biggest loading on the fuselage is probably the load from pressurization, which usual occurs once per flight cycle. Compare this to the wing structure (the wings are not pressurized). Here the biggest contributor to fatigue is likely the wings "flapping" in turbulent weather conditions. The amount of turbulent weather encountered is going to depend more on the hours in flight than on the number of flights. There is of course crossover. The fuselage will see changes in loading when flying through rough weather, and the wings do see a few cycles because they are "hanging" from the airplane (often heavy with fuel) when on the ground, and then the airplane is "hanging" from the wings in flight (a reversal of the forces on the wing, or a cycle).
When this happened I was working for Boeing with a guy whose dad was part of Boeing's quick response team whenever there was an incident like this. He told me that Boeing monitors how are their planes are being used and had warned Aloha about the added stress that their short flights creates. Boeing even offers models of the 737 in which fuel storage is reduced and the weight saved use to beef up the plane. Aloha didn't listen. Boeing, not being the FAA, couldn't make them. And yes, this was back when Boeing had a safety first culture.
@N. Warner Twas cold bond on the matrix doubler to the inner crown skin. Buncha salt and corrosion snuk in. BAC had already moved to hot bond/autoclave and now they have Chem-mill. Passengers should have known that 75,000 stretches on b-40 sealant wasn't gonna hold. C'mon.
I’m totally impressed by the heroism of the flight attendant trying to reassure the passengers! Wow, I cannot immagine what hell situation they lived...amazing flight crew, fantastic job!
Flight crews are awesome. I know a flight attendant in person. Their level of training and general ballsyness is something an average joe like me can only dream of. Remember: Their actual job is staying professional in nightmare situations, being probably the only ones in the cabin to keep a level head, and make sure a bunch of panicking people do the right things and survive. Only at times when everything is peachy and they do not need to perform their actual job, do they have time to push coffee trolleys around and smile at grumpy passengers. Remember that next time when you are waiting for your peanuts: The flight attendant might have something infinitely more important to do at the moment.
@@EnigmaticPeanut everyones life dpends on it. Desaster is bad enough, but panick spreading during a desaster is the absolute worst that can happen, worse than more parts of the plane falling off.
@@tonirose6776 such as examining the state of the door, flight control surfaces or engines and reporting it back to the cockpit, decide whether to force passengers to swap places to get someone to sit at the door who is likely to be able to actually open it in an emergency, inform colleagues on a passenger who needs to be watched closely to prevent a ruckus, any number of things.
I remember watching the Air Crash Investigation episode on this. I'm still amazed at just how incredible of an aircraft the 737 is to be so damaged and structurally compromised, yet still remain intact and in control. There are a lot of aircraft that would never survive what this 737 went through.
If any crew should be given an award for heroism and bravery under the worst possible conditions, it should be these guys. This is an example of the best of flying skills and extreme professionalism, all at the same time.
First off, RIP Clarabelle Lansing and my hats off to the pilots, crew, and everyone aboard that plane on that flight as they all acted heroically and all deserve mad respect for their actions that day to save lives. I just have to say this tho...those two dogs Petter has are so damn cute
I and my family were on this exact plane several months before this event. My father, who grew up in Hawaii, noted the name of the plane, Liliuokalani, since there was a landmark near him growing up with that name, Liliuokalani Gardens. I recall that the plane rattled a lot during the hop. I'm thankful that it was handled as well as it was. I don't have any issues flying, even knowing how close this could have been.
I currently live next to Liliuokalani Gardens. A little jungle in the middle of the city. Love the place if it weren't for the homeless living there now. What does that have to do with anything? Nothing. I believe I was on that plane too, but it is impossible to know at this point in time. I know all of Aloha's planes had names and they only had a few of them as they were a small company.
I remember my dad showing me, several years after this incident, the strengthening added to 737's exterior fuselage to prevent a similar incident. Maybe not the best time to show this to a child as you were boarding an airplane.
Sounds like something my step dad would do! It's his way of going "hey this is safe!" 😅 Means well

😂 The early 737s weren't manufactured correctly. And they didn't have proper premature fatigue cracking inspection programs for high-cycle airframes. Many 737NG's weren't made correctly either with substandard Ducommun structural parts knowingly slapped in on the Boeing assembly line, hence many more fuselage failures on hard landings and runway overruns.
I was on vacation in Hawaii with family, and the plane was delayed. I decided to tell this story while we we waiting to show why it's good to do maintenance rather than stick to the schedule. My mom was not amused.
A buddy's dad was on that flight. About 5 rows back from the "sunroof." Tough old Aussie. No big deal. At least that's what he said after a dozen beer!
Sent my buddy a link to this video. Hoping he comes back with some info about his dad's experience. I heard the story from his dad in a pub but it was well into the night and we'd been going hard.
No I literally don't think I can imagine that. I would be surprised if half the survivors didn't develop PTSD. All of them were battling the trauma for a while I'm sure.
I was living on Maui when this happened. My parents had moved there in ‘86 when I was 8 and I remember seeing this plane parked off the side of the runway with a blue tarp over its front missing section. Was very big news around the islands.
Honestly with the number of pressurization cycles and the accompanying hot/cold cycles these planes go through, it’s a wonder of engineering that the planes last as long as they do.
3 reasons I watch your videos: - amazing stories of airmanship - ways to learn from previous failures - how all the processes, checklists and so improved over time due to failures of the past - unbelievable stories how heavily damaged machine still managed to land This video covers all of them. Thanks!
Agreed. As a frequent flyer (who used to know very little about the manufacturing, maintenance, or operations of aircraft) I truly have a different perspective when I get on an airplane now. I never realized just how much is going on in the cockpit (and in ATC) while we're just sitting there waiting to takeoff and land. I will never take it for granted. I have a newfound appreciation and respect for air crews because of these videos.
I was born and raised in Hawai’i. I was there when this occurred. Crazy! It’s amazing that it held together and the pilots were able to land it. I cannot even imagine sitting in a seat up front and suddenly...the sky...the ocean...yikes! I saw the aircraft parked on the tarmac in Kahului the next week while I was on a business trip. The open cabin was wrapped/covered with blue tarps and the Aloha (airlines) logo in the vertical tail was painted over. I traveled back and forth to the outer islands quarterly from Honolulu. Guess which airline I used... Aloha Airlines is now defunct.
Great work Mentor! This accident was just as significant to the aviation industry as the de Havilland Comet decompression accidents of the 1950’s. Metal fatigue is no joke!!
I remember this incident so well from when it happened. The sight of this airplane opened up like that and people still in their seats, but still landing, was so shocking. It still is.
I remember the incident being in the news at the time, and I have read and watched several other articles/videos about the incident. My impression is that it's a miracle the fuselage didn't crack in half. It's probably very fortunate that this was a 737-200, with the short fuselage, before Boeing started stretching the 737 into aircraft that the original 737 design never contemplated. One has to wonder if one of the stretched versions could have survived a similar catastrophe.
Calling a situation of trying to land with no roof, one engine and a possibly failed front gear “almost silly” is British Airways Flight 9 levels of understatement.
@@megandunnett7900 When keeping a respectful distance from an active volcano is considered too expensive. Volcano science is not new at all, and it makes one wonder what they're being paid for, and also what obvious stuff is being neglected today and prepping the next disasters. (We are also fooled so easily.) I also remember an incident with a NZ tourism train being buried long time ago because it was running over a lava channel bridge, and their volcano vigil was of so little use that the volcano erupted and poured lava down that channel and buried the train exactly when it crossed the bridge. - And just like in good air travel tradition, only afterwards they started to practice due diligence.
@@Dowlphin You are correct in most things, but I dont think the "respectful distance" remark is completely fair considering how far the ash can reach. Yes, today we would ground airplanes in a a very big radius possibly if a volcano erupts, but considering this was a long time ago and the circumstances around it, its not really a clear-cut case of neglience as you seem to imply. Tragic, yes, avoidable, probably, but not obvious.
This incident is one of those 'episodes' in history that stand out in my past. I remember it being in the news when it occurred and I remember discussing some of the findings with my dad, specifically the metal fatigue issue as well as how the number of pressurazation cycles were much higher on the incident aircraft than on the average, mainland based 737-200 because it mainly flew multiple inter-island flights per day.
I remember the accident - it looked horrendous and it was real luck, that there was only one casualty. Especially now, as you told the whole story oft went wrong after the roof was blown off. A lot I didn't know. That's why I feel actually safer, when the captain does an extra inspection of possible cracks in the airplane, even if it delays the flight. I had this once in Frankfurt - a member of the loading crew had spotted something that could be a crack in the horizontal stabilizer. The captain inspected it and technicians came with a crane to have a look. As it turned out, this was only superficial in the paint. But although departure was delayed for almost an hour - I never felt safer aboard a plane.
When you consider the kind of damage that was going on in that plane, its a wonder the explosive decompression didn't lead to a total structural failure.
Great video, may that poor FA rest in peace. And the other one who still performed duties, and comforting passengers is a true hero. And your pups are absolutely adorable!!
I remember when that happened! So scary and so sad. That poor flight attendant; One can only hope she was rendered immediately unconscious, and had no idea of what was happening as she fell, rather than spending her last moments in abject fear and panic.
Fascinating how deep the stress analysis was by the Boeing engineers is on just that one lap joint. As a pilot and aircraft owner it makes me realize how much we take these designs for granted.
The margins of safety on aircraft structures are incredibly tight because of the weight limits. Those designs have to be right, and they have to be maintained and repaired right. There is very little wiggle room.
Excellent explanations, Mentour. The epoxy strips were a fabric back impregnated with low viscosity room-temp cure adhesives. They were meant to take the load of of pressure cycles but the useful lifetime estimates were based on hours used rather than flight cycles. With Aloha operating in the tropics, and their puddle-jumping mode of operations, they were probably seeing at least 2-3 times the cycle counts per flight hours than the estimates were based on. And the conditions they flew could cause epoxies to revert, the stresses of high cycle counts could cause the non-reverted adhesives to crack and flake, and the fabric substrate in the joint would wick moisture in. The wisdom of relying on epoxies for structural strength is on the same level as putting square windows in the DeHavilland Comet... something nobody really thought much of until after the problems became too clear to ignore. These days, the skin panels are designed to be held together to the plane by rivets, and the fay surfaces will be sealed with polysulfides which are soft and rubbery enough to survive cycling, won't revert in humidity, and are meant entirely to seal the joint and not expected to lend any structural integrity.
I read once a long time ago about how Fokker Friendships used epoxy but folded the butt section around a second piece of metal (or an interlock with the next sheet). It was unusual at the time but the insurers eventually liked it. I've always wondered about the actual engineering details. Off to G**g** now. I'm old enough to have clocked up a few miles in Friendships and used to enjoy the milk runs with lots of hops between cities. Flying lower is much more interesting but bumpy.
As I understand it, the question regarding "square windows in the DeHavilland Comet" has become misunderstood over time. The cabin windows were not entirely square, and in fact had rounded edges - where the misunderstanding comes in is that the fatigue cracks in the case of G-ALYP began at the "windows" surrounding the ADF aerials in the roof of the aircraft - these "windows" consisted of opaque fibreglass rather than glass. The original specification called for these window frames to be bonded in, but at some point a decision was taken to rivet them as well (presumably in an attempt to reinforce structural integrity). This was a late modification to the construction process, and does not appear to have been well thought through, because punch-riveting was used as opposed to drill-riveting. The problem with punch-riveting is that the process distorts the skin as the rivet is punched through, and this distortion is prone to cracking - the investigators came to the conclusion that this was very likely to have been the origin of the cracks which fatigue made worse in a much shorter number of cycles than would have been the case had the ADF windows been bonded in as per the original spec. The switch from rounded rectangular windows to oval windows in the cabin was the result of wanting to eliminate every possible source of cracking origins in order to restore public confidence in the Comet 4 - in fact the "tear strips" mentioned in this video were not only adopted by Boeing for the 707 and later types, but also by De Havilland in the Comet 4. Every subsequent British jetliner design was, if anything, over-engineered in terms of structural integrity - which came with minor, but noticeable weight and performance penalties.
The Yankee (later Grumman) AA-1 series of light aircraft were manufactured by bonding (glueing) the aluminium panels together, with minimal rivetting. De-bonding accurred in service, requiring in-service rivetting.
I lived in Hawaii when that happened. I met one of the passengers who was on that flight. He had to file a suit against a photo processing facility because they kept the original negatives and sold the photos he had taken.
I had to quit using a developer after "the one magic negative" was clipped from the middle of a roll. It's heartbreaking to do a job culminating in a picture that will change your life and someone steals it.
@@cmw9876 So that's not just happened to me then. Fortunately I took the shot again and got a successful development the second time via another developer. Still, even Kodak managed to lose 1 image in the middle of a roll of film !

Your 2 co-pilots are similar to my two poodles (Molly & Jess) who I flew back home to the U.K. from Saudi Arabia. I also flew my grey poodle, Dina, home from Kuwait in the 1980s after rescuing her. All my poodles were experienced fliers 😂. Thank you so much for these videos. They are addictive viewing, very interesting to watch despite knowing nothing about flying an aeroplane.
I didn't notice you mentioning the exceptionally high number of landing cycles per hour on these interisland flights. I grew up in Hawaii and remember this incident very clearly. Aloha took a lot of heat, but I remember one of the things that propagated through all carriers was that they needed to do certain maintenance and inspections based on landing cycles instead of purely by flight hours.
Is that because lots of short cycles contain more take offs and landings, so a long flight pattern will be a lot less stressful but show the same amount of flight hours?
@@dionlindsay2 Well it actually depends on which part you are talking about but for the skin of the aircraft yes the cycles of expansion and contraction of the fuselage with each pressurization is the dominant factor. In this regard, it is similar to how freeze-thaw cycles need to be taken into account when calculating inspection intervals for critical structures on the ground, water getting in to and then cyclically expanding and contracting with the freeze-thaw has a similar effect of applying pressure to any weak point that does develop massively accelerating the propagation of cracks. The main difference is that water freezing pushes the parts of the crack apart whereas in pressure vessels the pressure differential pulls the crack apart but either way repeatedly jacking the crack open causes the stress concentrations at the end of the crack cause it to grow at the ends until the part fails or properly conducted inspections detect and stop the growth of the cracks.
@@seraphina985 Wow, thanks for such a detailed answer. I had just assumed the take off and landing bits were hardest on engines. But expansion and contraction I get (I was a duffer at sciences but I remember teachers getting me to understand a bit about the coefficient of linear expansion). Thanks for the friendly answer :-)
@@dionlindsay2 Well the cause of the expansion is different in the case of the hoop stress on a pressure vessel but the vessel does indeed expand and contract a little. There is no such thing as a truly rigid body all materials are at least somewhat flexible and will deform to some degree when subjected to variable loads of any kind. Not usually enough to be perceptible but it is enough to slowly wear on the internal structure of the material over time. For a tubular pressure vessel like an aircraft fuselage or say a pressurized pipeline you have stress trying to pull it apart in every direction which does cause the radius to expand slightly and also the length to be stretched a little (hoop stress and longitudinal stress respectively). Over time this is what leads cracks to begin to develop at any stress concentration points and expand from there (Rivets or any discontinuity in the material properties of the structure ie windows in an aircraft or welds between sections of a pipe or whatever.
Back when this happened a friend of mine was one of the investigators he said the only thing that held that plane together when it landed where the strips of metal that the seats were bolted to otherwise it would have folded up when it came in contact with the runway
The underbody skin also helped. The front of the aircraft is the least stressed part of the airframe. If this had happened between the wings and the tailplane, your scenario would probably have come to pass-- while airborne.
I was a 727-200 captain at the time of this incident and remember that my employer was very quick to issue reassurances that our fleet consisted of the later, differently constructed. model. I had forgotten this all but now I'm off to Google to find what the differences were. You can retire from flying, but you can't stop being a pilot I guess,
Excellent explanation of this incident. I remember it clearly. Having flown on similar flights in Hawaii in the mid seventies I know that the Aloha and Hawaiian Airlines aircraft had a far greater number of cycles than most other airlines. The pilot and first officer did a remarkable job getting this plane down onto the runway. Thank you for explaining this incident so thoroughly.
KazakhToon I feel vindicated reading your comment/this thread...in fact, I think it would be a good idea for them to be fixed in the corner of the screen throughout the video. They're the cutest little dogs.💗🐕🐕
*A good buddy of mine was on this flight (YEARS before I ever knew him) as an almost-tween. He was in the row (I believe port side) one ahead of the over-wing escape windows. It would be many years b4 I ever met him, but alas, I never would have but for some great airmanship by the crew.*
I recommend that if passengers see something of concern, they should report it to the pilot or co-pilot. Several years ago we were on a flight from Honolulu to Lihue, Kaui, when I informed the flight attendant that there was whistling sound coming from one of the windows. The flight attendant told me it was nothing to be concerned about but I knew that wasn't correct & I insisted on speaking to the pilot or co-pilot. He turned white when I informed him, they lowered the altitude the plane was flying at, and they grounded the plane until it could be repaired. I wish I could say that was the only time that happened but it happened again on a flight from Edmonton to Calgary which was going to continue on to Toronto as its last leg of the flight. I got the same response from the flight crew but I informed them that rapid decompression could occur & asked to speak to the pilot or co-pilot. Thankfully the plane was then grounded in Calgary for repairs. I shudder to think what could have happened if I hadn't insisted on speaking to the pilots/co-pilots as passengers could have been in danger of being sucked out of the plane if the window blew out & rapid decompression had occurred. I knew about rapid decompression from my training to be a flight attendant but went to university instead rather than be a flight attendant. (Sharen)
@@daren32909 i don't understand why people like you and @Julia always 'call bs' when there's so much detail in a comment. You think that people who experience things in real life don't use the internet and comment on stuff? Or is there a group of people on the internet just going around calling everything bs as a hobby?
I've never heard such a detailed analysis of this incident! But it was miraculous that the pilots and crew were able to safely land the aircraft and save so many lives. Thank you for making this video!
I remember seeing this on the news when it happened and was flabbergasted that the aircraft could even fly in that condition, and could only imagine the horror of the passengers, particularly those in the open.
One of your best videos, Petter. I remember very well the accident when it was broadcasted on the news and I felt (and still feel) extremely sorry for the poor lady who lost her life, but also admired the pilots' skills that allowed to land the plane safely. BUT overall I like your pragmatic and systematic approach, your digging into the crucial facts, avoiding any sensationalism; and I love the way you present the conclusions and the lessons learnt. Well done!
so often in these stories the flight attendants are the unsung heros, its really amazing even after that whole roof was gone she still risked her life to crawl around and comfort passangers.
One of my friends is ex-crew and as far as they are concerned, once they are in the air, it's their plane and they will protect it and everyone in it until it's back on the ground. (so don't annoy them when you're on board because they are your friends!).
I’d love to show this and the Hudson video (in particular) to all those who make derogatory comments about flight attendants. Thanks for another excellent video.
This man is a great host... very informative and sound experience as a 737-pilot. I'm a Marine Corps combat-veteran--I flew the F-4 Phantom "wild weasel" until a career-ending combat injury during the Gulf War. Some of my greatest memories were early morning training sorties out of MCAS El Toro California. I could pull the nose up, the elevators (vertical stabilizer) would move upward, forcing my climb attitude for a quick 600 knot push to the ceiling @ 20,000 feet. In seconds I could level-out and watch the sun rise before the rest of the West Coast could... It was akin to walking on water with Jesus Himself. "MENTOUR PILOT" brings back great memories, and those of tragic accidents for which I witnessed in both training and combat actions, that causes me to miss my days of flying Mach II through the desert and over the Pacific. Semper Fi!
This happened the same year my wife and I got married (actually about 5 months before) we honeymooned in Hawaii and still took 737s to fly from one island to the other but kept our seat belts on the WHOLE time! Metal fatigue salt air environment. I guess metal fatigue notwithstanding Boeing built a pretty solid plane!
Just like I was driving on the I35 bridge over the Mississippi River in Minneapolis two weeks before it collapsed in 2007. I was also on a plane flying from Philadelphia to LA on 9/11/01, but it wasn't one of the ones that went down. Sometimes we're luckier than we realize.
I love this series of videos, very well done and very informative. Please consider doing one on PSA flight 182 which collided mid air with a Cessna over San Diego in 1978 (which I remember vividly). I believe at that time it was one of the worst air disasters in the US. Keep up the great work!
I want to thank you for how you present these cases and walk us through not only what happened, but why, and in such a way that the images you use in the video serve to accentuate what you are talking about instead of you relying upon them completely. I listen to these primarily while I'm working outside, and your ability to verbally paint a picture while maintaining calm professionalism is greatly appreciated. Thank you!
Amazing that this plane stayed together through all that. The engineering of planes these days, the skills of the cockpit crew and cabin crew, , and some luck made this much better than it should have been. Sad there was loss of life and the fact that it could have been worse doesn't change the fact that she's gone but thankfully they were able to minimize loss of life as much as they did.
I loved being updated on this particular accident. I was working as a flight attendant with TWA at the time. Hired in 1974 as one of the few male F/A''s in the at time. You've added great depth to this incident...Thank you!
I've just noticed Mentour's sofa cushions are in a navigation lights configuration, red on the left, green on the right. If his wife or kids swaps them round, would he face away from the camera when doing these videos?
It’s a function of the locale. Up until March, I used to fly between Honolulu to Kahului on Maui fairly regularly. From the time where the aircraft pushes back from the gate ‘til the point where you get off on the other side is about 45 minutes at most. Each interisland flight that comes in disgorges its passengers, and then nearly immediately, boarding starts for the next leg. Between HNL and OGG, the cycle time is a little more than an hour, and under normal circumstances, flights run from about 5:30 am ‘til about 10pm, so it’s possible an aircraft can do 10 cycles a day on this particular route. I don’t know how long each aircraft spends in maintenance, but it can’t be that long since this aircraft was built in 1969 and failed nearly 30 years later, so call availability 300+ days a year. I’m from half a world away, but my wife is from here and she remembers the coverage on TV and in the papers at the time.
@@MentourPilot I wish you put more emphasis in your video about the significant about the discovery of cycles needing to be separately tracked from flight hours; if I'm not mistaken, the pressurization and depressurisation cycle is the most damaging part of an aircraft flight, in terms of metal fatigue. I would imagine that long-haul aircraft would actually have exceptionally long lives in comparison, because even though they traditionally would have significantly more flight hours, the amount of metal fatigue the body experiences would be much lower. Actually, speaking of air accidents, I would love to see do a video on a flight where the pilots of an asian 747 got disoriented, fell out of the sky, accelerated beyond design limits, until they saved it at the very last minute, and landed safely. Apparently it even ripped parts of the tail off from the velocity. I forget what the flight was called. The reason I'm bringing it up is because this story reminded me of a very weird quirk that was permanently etched into this particular 747 for the rest of its service life: the wings had a permanent upward bend of about 1 degree. 😅 I would be curious as to how much that would affect the plant handling going forward.
@@TheEDFLegacy It was a 747 belonging to a Japanese airline. One engine flamed out at high altitude and, instead of descending to a lower flight level to restart it (where the air is denser), the crew tried a high altitude restart. Lacking adequate thrust, the plane banked and entered a dive.
As a non-destructive testing (NDT) technician, part of my job is using testing methods (ultrasonic testing, for instance) to seek and report those cracks in a piece of metal of other material, in order to prevent this sort of things from happening. This example of flight 243 was given to us during the training, and this video made it all very interesting and "real". Thanks!
@@sharoncassell9358 Oh yes, absolutely! Actually I only work on composites. Those are laminated (several sheets of fabric on top of each other), so you very much see each layer and if they bond well together (disbondings are bad and detected with ultrasound). You can also see porosity and foreign objects (a chunk of paper or plastic, for instance). Some techniques are not possible in layered fabric like composites (such as using transverse waves), but those are not really required with composites since we mainly use them when testing metallic solderings. I mainly work on carbon fiber, glassfiber, and kevlar-fiber. Each one has is own specificities and some are more easy to test than others (glassfiber is very absorband, so the wave rapidly decreases when the material gets thick), but otherwise it’s totally possible and also widely used :)
Ahhh... the wonderful story of Aloha Airlines. Although it's tempting to make a quip about fresh air, it is tragic that someone died during this flight. That being said, I am very happy that it led to some very meaningful and impactful changes that are still felt to this day. Thanks Mentour! I hope you cover the Comet at some point, as there is a LOT of crossover with this particular incident.
If watching videos on crashes makes you nervous, remember this: every time an airplane crashes, chances are, your next flight just got at least a little safer.
Exactly !! Like the race car drivers (test dummies) that walk away from horrific crashes. Or football players who have knees destroyed but come back to play again !! Cars get safer and surgeons learn more. We owe them.
Actually, I've found comfort in it, not that I was ever particularly scared of flying before. I now know which bits of the airplane we can have fail and still make it safely to the ground, or, if not safely, at least have a possibility of surviving.
I can be a nervous plane passenger at times, but I think the soothing calm demeanour of your presentation, the way you use these accounts as a way to show how things have improved, or things to watch out for, and those adorably floppy dogs lying so peacefully besides you as you go through these difficult stories...somehow all of this makes up up a very soothing and calming environment, that I will probably think of the next time i find myself being nervous on a plane.
An absolutely incredible story! I can't believe the pilots managed to get the plane down in those conditions, and that the flight attendants (RIP Clarabelle Lansing) were able to keep the cabin calm. Puts my faith in pilots after a few scary stories of their negligence.
I was ticketed on that very flight! The last moment one of my instructors at UHH wouldn't let me miss a class so I didn't go to HNL to go clubbing. I normally sat up front and knew Mimi casually. Such a tragedy but kudos to the crew. I've wondered how I would have reacted had I not missed that flight. What it did do was to peak my already interest in aviation and ended up going to a professional pilots school after UHH and worked in aviation my whole career. Very rewarding, but be prepared for industry ups and downs. Listen to what is said here as you need to be a pilot first, equipment operator second.

Most engineers and stressmen know that you don't arrange rivet patterns in straight lines (because of the tendancy to 'tear along the line'). Adjacent holes should be off-set in good engineering practice - this has been known about since the early days of making boilers for steam engines !

Thank you for this info.
I was on a flight recently where the pilot informed us that a bird strike had occurred on the previous flight. He said that they were going to delay the flight till they were certified to take off by an inspection team. The guys sitting in front of me started complaining about it, saying they were wasting time, but I was grateful that they cared enough about keeping the aircraft operational and safe.
Ask the guy if he would complain about dying....
I had a similar situation. We were getting ready to push back from the gate when the captain said that there had been a bird strike near the tail on the previous flight which left a small dent that had to be measured. I don't know what the specs were but aviation enthusiasts would know, it couldn't exceed a certain width, length, and depth. He even told us what it was at the time. He was very transparent about what was happening, which put everyone at ease because we weren't just sitting there nervously watching maintenance people outside the aircraft with no idea what was going on. Everyone relaxed and took it in stride, knowing this meant the dimple would either be out of range and we would deplane and switch aircraft or it would be within tolerance and we'd take off. Everyone was actually pretty cheerful. I didn't hear any complaints. In fact, all around me people were laughing & saying "better safe than sorry," and joking about the condition of the bird. It turned out not to be serious enough to ground the plane and we took off. But the key was the captain's transparency. It was only because he was completely honest with us and detailed about what was going on that nobody was concerned about the delay.
Some people are both stupid and ignorant. They would have been the first to call their lawyers if an "event" happened!
that guy sounds like the kind of guy to start a fight and then sue the other person for fighting him. when he was the one who threw the first punch
"Engine failure after takeoff", I can't believe this airline would put my life at risk like this, I am going to sue!
Clarabelle "CB" Lansing had more than 30 years of experience as a flight attendant and is really heartbreaking that they never found her body. May she rest in peace

I was an RN working at the hospital a mile from the airport on Maui when this happened. It was my day off, but I got a call from the hospital saying there was a level 3 disaster and asking me to come in. I knew not to waste time asking what it was. I hung up and headed in. On the way, I passed the airport and sitting on the tarmac was a plane that looked like it had been opened up with a can opener. The hospital was packed with all the passengers being triaged by what looked to be every single healthcare provider on the island. Most of the passengers had cuts and eye irritations. Five were more serious. I heard stories of passengers in the aisle seats holding onto those buckled into the window seats where there was no wall. I understand the phenomenon of not really seeing something critically that has never occurred before, even with the bulletins. That is the problem with unprecedented occurrences. That it happened first (and probably last) in our heavily salty air with very high cycles, is not surprising either. I used to windsurf on a beach right next to the airport. After the accident, we could turn around and see that torn apart aircraft sitting there for weeks. Very sad, but a fantastic job by the crew, first responders, and the hospital.
I can't imagine the chaos in that ER. It must have been busy already (the ER always is), and then 150 passengers crowding in there all at once must have been overwhelming. Good for you for just dropping everything to go and help these people, to try and ease the tension on the hospital
As a fellow RN, I applaud your devotion and swift, appropriate response! Inspirational truly.
Wow! Maui Memorial?
Thank you for your dedicated service to the medical industry ❤ I can’t imagine the horror of seeing that shredded aircraft on your way to the hospital that day. Horrible.
@@trumpetmama82 Yep, the one and only.
My biggest takeaway was the crew member that was crawling up and down the aisles trying to reassure the passengers that everything would be okay. She deserves some kind of medal for bravery
And a big fat retirement bonus. She shouldn't have to fly or work again.
The whole crew sounds like they deserve awards. The pilots appear to have done pretty nearly flawlessly under the circumstances, circumstances they couldn't have really trained for, not entirely.

It isn't. I'll let the investigators sort this stuff out.
Very true. Natural conversation. I love that about people who show that they are actually pausing to think. Which means they're doing this completely authentically as opposed to the fakery of Mainstream Media and Co. where it feels like we're just the guinea pigs for alreadyprepared propaganda programs in a simulation.
Great comment
I love how the two dogs fell asleep during storytelling

I imagined they were dreaming while listening to the story subconsciously. Can you imagine being a dog, hearing and only understanding maybe 15% of the story and dreaming about chewing on a cable? Suddenly you wake up and think its your fault the plane crashed. I know its absurd. I mean, I'm a human and awake and I only understood maybe 30% of the story.

In all seriousness though, you really are doing aviation a great service. I hope you get officially recognized for it some day. Keep up the great work.
the insane part is that the roof got ripped off, pieces got into the engines, and they STILL managed to land safely.
Being a trained accident investigator myself (but for trains) I find these videos really well made.
Much more factual and less "sensational" then commercially produced "Air Crash Investigations" type TV shows.

Let the fbi in to your investigation if you want sensationalized crap. Twa 800 anyone.
Rest in peace Clarabelle "CB" Lansing, flight attendant, Aloha Airlines flight 243.
I'm very sad that she passed away.
Speaking of that flight attendant, when I watched the Air Crash Investigation episode for this particular incident, apparently there is an alternative theory call Fluid Hammer, which is when a fluid object hits a small area, it creates a hammer effect that creates tremendous force; it is similar to how when you drop a plug into a sink or bathtub, you will notice a sudden increase in suction as it gets very close to the mouth of the drain.
According to the engineer, he hypothesizes that it was possible that the plane in fact tore as designed, but the flight attendant what sucked into the hole. But as the tear strips are smaller than her frame, it created the same effect, and essentially created a pressure spike, which caused the rest of the weakened frame to cascade fail until there was insufficient force and metal fatigue for the tear to continue.
To my understanding, the FAA rejected the conclusion, but did state the concept deserved further study.
But it also makes me cringe because that meant her death was far more brutal than what's suggested by this report. With that in mind, I hope her death was instant, which I suppose is better then simply being sucked out and falling while conscious.
@@TheEDFLegacy Unfortunately, there is basically not such thing as an "instant" death. All we can hope is that she did not have time to understand what was happening.
@@DrewNorthup Typically, the concept of "instant death" involves a level of trauma that I dare not wish to describe here. In other words, brain function is instantly silenced. That being said, this may not have happened here, and I hope she passed out extremely quickly.
The Legacy I was fascinated by this theory!
They believe CB Lancing was blown through the hole that appeared and got stuck, causing the Fluid Hammer Effect, causing the rest of the damage. ( Fill your bath and take the plug out, then replace it, you will notice there is a shock and the plug gets pushed back down.)
I’m a fuselage structure mechanic with 15 years experience, and I’m damn impressed with how concisely you explained the basics of the design to illustrate how the lap join cracking developed and caused the failure. Well done sir.
Is the 737-300 designed differently so this can't happen?

As an engineer friend told me one time, “A doctor’s error can kill one person at a time. An engineer’s error can kill hundreds at a time.”
@@GooberFace32 I'm saving this one.
My fathers friend was a passenger on that flight, when the decompression happened, he had all of the oxygen sucked out of his lungs and had great difficulty starting to breathe again. He said it was absolutely terrifying and thought he was going to die. As they were landing he realised his shoes had been sucked off his feet and were gone.
I worked with a guy who was on that flight. In normal conversation at work, he was always the type to throw in a joke or two. But when this flight came up, I've never seen anyone so serious in my life.
is that how sudden decompression works? i always thought you dont notice it and you slowly become essentially drunk and then pass out by lack of oxygen, i was not aware you can have air sucked out of your lungs, i just don't think it works like that but I don't know so thats why im asking, if anyone knows.
@@Auron710 this is explosive decompression there is also the slower decompression both are dangerous but the explosive type is hard to miss.
@@Auron710 it would suck the air out of you because of the difference in pressure that is why the cabin ruptured also
@@Auron710 In the past I was driving motorbikes. That is ok as long as the speed stays under 160 km/h. When you go faster till 195 km/h, it feels like the wind is trying to rip off your helmet with a force equal to a bucket of water of 10L, equaling 10 kg. I did not experience faster speeds on a bike, but went on in windturbine design. There is a lot of power in air and wind, which is air in motion, but also in vacuum, which is the lack of air. Nice things to play with in windpower design…

What horrible final moments for the poor cabin crew member that must have been. RIP :(
At that original high altitude, she would have quickly passed out from lack of oxygen, at least I hope so.
Sounds awful, but I kind of hope she was struck in the head, snapped her neck, or something in the process of being ejected and basically killed instantly or lost conciousness.
Hopefully she was rendered unconscious by her head striking the aircraft fuselage as she was sucked out and knew very little.
I have a feeling she didn't know what happened 😢

My family and I flew on this aircraft (N73711) from Honolulu to Kauai then to the Big Island about 4 weeks before this accident.
We were meant to go direct from Honolulu to Hilo but we got on the wrong plane and ended up doing a detour through Kauai.
I remember this aircraft vibrating a lot and making all sorts of strange noises, felt like it was held together with chewing gum.
I have a photo of me taken on board with a look of concern on my face.
The flight attendant told me 'This plane always rattles."
I'm now a Aircraft Maintenance Engineer (A&P) for a airline and have never been on a aircraft like that since that scared the hell outta me more than this one did.
@@Flarptube The aircraft involved was the 152nd Boeing 737 airframe. It was built in 1969 and delivered to Aloha Airlines as a new aircraft. Its registration was N73711[4] and it was named Queen Liliuokalani after Lili'uokalani.

All Boeings do that. They're incredibly poorly built aircraft compared to Airbus.
@@Flarptube 737-200s were designed to hold on 60 000 cycles, this one had 90 000. I can think about the female passenger that remarked the crack on the left side of this aircraft when boarding.

They always talk about the miracle on the Hudson but this can go down as the miracle of Hawaii
So impressive how everyone kept their cool and kept working all the way through. I saw interviews with some of the passengers and they were doing everything they could to support each other too.
It is astonishing how an aircraft can lose so much of its fuselage and not totally disintegrate.
I have read that one passenger, who was interviewed after the incident, actually noticed tears between the rivets, just to the right of the entry door, as they boarded the aircraft. She mentioned the issue to her traveling companion but not to the crew. In addition, this particular aircraft, and others owned by the airline, underwent far more 'pressurization cycles' compared to the expected 'average'. This was due to the 'short hop' operation in the Hawaiian Islands. Far more 'take offs', 'landings', 'pressurization' and 'de-pressurizations' than 'average' for hours of flight time. Amazing only one was killed. God Bless her and her family.
I had been on Delta 1989 in US. Birmingham Al. I never heard the outcome. Another one in 1996 when we deplaned due to a bomb scare. Turned out it was no bomb but a fool playing with fire. He sprayed hairspray from a can and lit a match. They arrested him but we had to wait 2 hours in Phoenix to continue on to Las Vegas. Meanwhile I'm not afraid to fly. I still go to Vegas CA TX DFW Hawaii and Florida to Minnesota. My family is spread all over and I stayed on a train for 4 days to get from east coast to west coast. It was scenic deer and moose birds snow waterfalls but if you're in a hurry 4 to 5 hours and you arrive in Calif.
I heard about that, too! It's so important for passengers to tell the crew of any abnormalities they notice. Hell even if it's something completely normal that they mistake for being odd, you're still better off telling the crew.
I have worked for a MRO responsible of the cabins' refurbishment as an engineer specialized in structural components.
Most of my job was to perform decompression analysis, as the new cabin included implementation of new seats for example.
These decompression analysis are mandatory to allow an aircraft to go back to flying, because the biggest risk is a decompression like in this accident: loss of part of the floor that contains some of the cables that operate the flight controls.
The most critical load case is an opening in cabin (door or portholes opening...) while the cargo bay is completely empty. indeed, the volumes of air in the cargo is huge without any cargo in it, but at the beginning of the event only the air in the cabin can exit. Therefore, there is a period (few seconds) where the cargo is full of air while the cabin is empty. This results in a very high load applied on the floor from the bottom to top which could lead to a floor breakout.
This is why since this accident we have seen emerging new device appear to regulate pressure between cabin and cargo called Dado panel (Airbus) / Return Air Grid (Boeing). Those are basically opening that allow the air to pass from the cabin to the floor (along the shear truss at the floor) to the cheaks sections in the cargo, finally reaching to cargo as the straps in the cheek break because of pressure (obviously working from cargo to cabin depending on the blow-out location).
Most of the engineering work consists in the analysis of the obstruction of those dado panels to determine whether the floor could sustain the load of a decompression. indeed, these panel are partially covered by the seats (mainly business seats), and therefore reduce the amount of air that can go from cabin to cargo.
Sorry for this big (and boring) cobblestone, but I figured it might interest a few people, since we were perfectly in the theme :-)
I'm curious why a hole above the floor worse than one below in the cargo compartment? As I'm sure you know, airplanes have been lost due to cargo area decompression. Also, don't most passenger aircraft have substantially more air volume above the floor than below it? Wouldn't this larger volume control the minimum through-floor venting required?
Problems have occurred where dado panels were not fitted and the decompression event occurred first in the cargo hold. Partial collapse of the floor area jammed flight control cables, which typically run under the floor , caused loss of control to tail flight surfaces .

After listening to the video about the pilot who allowed his kids to fly, the pilots who wanted to join the 41k club (I think it was 41k) and the ones who hit the water twice it was good to hear a video where the pilots didn't cause the accident
I am a very nervous flyer, but this video actually made me feel better, that so many things went wrong and they still landed the plane with only one casualty.
As long as flight controls and aerodynamics that is left, allow pilots to get to the ground in controlled fashion, any visually horrifying structural damage is just.. visually horrifying. For instance damaged elevator or fixed in some extreme position with aircraft looking pristine, would likely be fatal. Luckily there is some redundancy in systems in aircraft and airliners have great gliding capability (much better than your 4-seat Cessnas), so even loss of all engines is almost "standard procedure" for good pilot if happens at safely high altitude.
since I started working in teh aviation industry its made me realize how many things go wrong that the passenger has no idea about! A few weeks ago one of our aircrafts had 16(!!) seagulls go through the engine and everybody was fine afterwards. Went back to base and there were just some fanblades that had to get switched out.

Yet ANOTHER *combination of factors* leading to disaster.
Engineering + construction + maintenance shortcomings. This would never have happened in the UK or US aviation industry in the 50s, 60s. Safety, quality, reliability as legacies from WWII military mindsets and specifications.
@@thedolphin5428the plane was built in the 60s

So what. Certain maintenance checks and procedures were supposed to be done in the 70s, 80s to prevent the roof flying off. And besides, not all, nor even one other identical model has lost its roof. So there goes your argument that age was particularly responsible. The investigaton clearly showed glue failure, *unchecked and unaddressed* material fatigue, despite a manufacturer bulletin.
Had to study this failure in one of my mechanical engineering classes. Also, Boeing wasn't considering high cycle flights in their bulletin to require more in-depth inspections. Aloha was unique in were Boeing often thought in hours of flight time to do more invasive and rigorous inspections, this was a classic cyclic fatigue in a moist and salty environment which should have required more frequent and rigorous inspections because of pressurization cycles (impacted by the number of flights), not vibration cycles (which are more flight-time dependent).
@Playford Seven Fatigue in the fuselage structure is more dependent on flight cycles. That is, the biggest loading on the fuselage is probably the load from pressurization, which usual occurs once per flight cycle.
Compare this to the wing structure (the wings are not pressurized). Here the biggest contributor to fatigue is likely the wings "flapping" in turbulent weather conditions. The amount of turbulent weather encountered is going to depend more on the hours in flight than on the number of flights.
There is of course crossover. The fuselage will see changes in loading when flying through rough weather, and the wings do see a few cycles because they are "hanging" from the airplane (often heavy with fuel) when on the ground, and then the airplane is "hanging" from the wings in flight (a reversal of the forces on the wing, or a cycle).
When this happened I was working for Boeing with a guy whose dad was part of Boeing's quick response team whenever there was an incident like this. He told me that Boeing monitors how are their planes are being used and had warned Aloha about the added stress that their short flights creates. Boeing even offers models of the 737 in which fuel storage is reduced and the weight saved use to beef up the plane. Aloha didn't listen. Boeing, not being the FAA, couldn't make them. And yes, this was back when Boeing had a safety first culture.
Each flight of Aloha 737 was in mere minutes, with so many takeoff and landings daily. I heard of people flying almost daily there.
Yeah, Hawaii weather corrodes everything man, something new looks like junk in 6 months :(
@N. Warner Twas cold bond on the matrix doubler to the inner crown skin. Buncha salt and corrosion snuk in. BAC had already moved to hot bond/autoclave and now they have Chem-mill. Passengers should have known that 75,000 stretches on b-40 sealant wasn't gonna hold. C'mon.
I’m totally impressed by the heroism of the flight attendant trying to reassure the passengers! Wow, I cannot immagine what hell situation they lived...amazing flight crew, fantastic job!
their life may depend on the passengers remaining calm.
Flight crews are awesome. I know a flight attendant in person. Their level of training and general ballsyness is something an average joe like me can only dream of. Remember: Their actual job is staying professional in nightmare situations, being probably the only ones in the cabin to keep a level head, and make sure a bunch of panicking people do the right things and survive. Only at times when everything is peachy and they do not need to perform their actual job, do they have time to push coffee trolleys around and smile at grumpy passengers. Remember that next time when you are waiting for your peanuts: The flight attendant might have something infinitely more important to do at the moment.

Man being sucked out of a plane, certainly up there when it comes to worse deaths
I and my family were on this exact plane several months before this event. My father, who grew up in Hawaii, noted the name of the plane, Liliuokalani, since there was a landmark near him growing up with that name, Liliuokalani Gardens. I recall that the plane rattled a lot during the hop. I'm thankful that it was handled as well as it was. I don't have any issues flying, even knowing how close this could have been.
I currently live next to Liliuokalani Gardens. A little jungle in the middle of the city. Love the place if it weren't for the homeless living there now. What does that have to do with anything? Nothing. I believe I was on that plane too, but it is impossible to know at this point in time. I know all of Aloha's planes had names and they only had a few of them as they were a small company.
I remember my dad showing me, several years after this incident, the strengthening added to 737's exterior fuselage to prevent a similar incident. Maybe not the best time to show this to a child as you were boarding an airplane.
Sounds like something my step dad would do! It's his way of going "hey this is safe!" 😅 Means well
😂
The early 737s weren't manufactured correctly.
And they didn't have proper premature fatigue cracking inspection programs for high-cycle airframes.
Many 737NG's weren't made correctly either with substandard Ducommun structural parts knowingly slapped in on the Boeing assembly line, hence many more fuselage failures on hard landings and runway overruns.

I was living on Maui when this happened. My parents had moved there in ‘86 when I was 8 and I remember seeing this plane parked off the side of the runway with a blue tarp over its front missing section. Was very big news around the islands.
Honestly with the number of pressurization cycles and the accompanying hot/cold cycles these planes go through, it’s a wonder of engineering that the planes last as long as they do.
3 reasons I watch your videos:
- amazing stories of airmanship
- ways to learn from previous failures - how all the processes, checklists and so improved over time due to failures of the past
- unbelievable stories how heavily damaged machine still managed to land
This video covers all of them. Thanks!
Agreed. As a frequent flyer (who used to know very little about the manufacturing, maintenance, or operations of aircraft) I truly have a different perspective when I get on an airplane now. I never realized just how much is going on in the cockpit (and in ATC) while we're just sitting there waiting to takeoff and land. I will never take it for granted.

As a structural engineer I have to say you did an amazing job explaining the fatigue failure of this aircraft.
Great work Mentor! This accident was just as significant to the aviation industry as the de Havilland Comet decompression accidents of the 1950’s. Metal fatigue is no joke!!
Correct!
@@Die-Angst "just as significant" means "equal in significance"
I remember this incident so well from when it happened. The sight of this airplane opened up like that and people still in their seats, but still landing, was so shocking. It still is.
It was like a can opener sheared the roof off.
I remember the incident being in the news at the time, and I have read and watched several other articles/videos about the incident. My impression is that it's a miracle the fuselage didn't crack in half. It's probably very fortunate that this was a 737-200, with the short fuselage, before Boeing started stretching the 737 into aircraft that the original 737 design never contemplated. One has to wonder if one of the stretched versions could have survived a similar catastrophe.
Calling a situation of trying to land with no roof, one engine and a possibly failed front gear “almost silly” is British Airways Flight 9 levels of understatement.

I also remember an incident with a NZ tourism train being buried long time ago because it was running over a lava channel bridge, and their volcano vigil was of so little use that the volcano erupted and poured lava down that channel and buried the train exactly when it crossed the bridge. - And just like in good air travel tradition, only afterwards they started to practice due diligence.
@@Dowlphin You are correct in most things, but I dont think the "respectful distance" remark is completely fair considering how far the ash can reach. Yes, today we would ground airplanes in a a very big radius possibly if a volcano erupts, but considering this was a long time ago and the circumstances around it, its not really a clear-cut case of neglience as you seem to imply. Tragic, yes, avoidable, probably, but not obvious.
Holy Molly, inside of all that bad situation, they were blessed and those pilots are a chads.
This incident is one of those 'episodes' in history that stand out in my past. I remember it being in the news when it occurred and I remember discussing some of the findings with my dad, specifically the metal fatigue issue as well as how the number of pressurazation cycles were much higher on the incident aircraft than on the average, mainland based 737-200 because it mainly flew multiple inter-island flights per day.
I remember the accident - it looked horrendous and it was real luck, that there was only one casualty. Especially now, as you told the whole story oft went wrong after the roof was blown off. A lot I didn't know.
That's why I feel actually safer, when the captain does an extra inspection of possible cracks in the airplane, even if it delays the flight. I had this once in Frankfurt - a member of the loading crew had spotted something that could be a crack in the horizontal stabilizer. The captain inspected it and technicians came with a crane to have a look. As it turned out, this was only superficial in the paint. But although departure was delayed for almost an hour - I never felt safer aboard a plane.
I wouldn't call having "only" one casualty "lucky". Especially when this whole thing not only could but should have been avoided.
When you consider the kind of damage that was going on in that plane, its a wonder the explosive decompression didn't lead to a total structural failure.

Fascinating how deep the stress analysis was by the Boeing engineers is on just that one lap joint. As a pilot and aircraft owner it makes me realize how much we take these designs for granted.
The margins of safety on aircraft structures are incredibly tight because of the weight limits. Those designs have to be right, and they have to be maintained and repaired right. There is very little wiggle room.

Excellent explanations, Mentour. The epoxy strips were a fabric back impregnated with low viscosity room-temp cure adhesives. They were meant to take the load of of pressure cycles but the useful lifetime estimates were based on hours used rather than flight cycles. With Aloha operating in the tropics, and their puddle-jumping mode of operations, they were probably seeing at least 2-3 times the cycle counts per flight hours than the estimates were based on. And the conditions they flew could cause epoxies to revert, the stresses of high cycle counts could cause the non-reverted adhesives to crack and flake, and the fabric substrate in the joint would wick moisture in. The wisdom of relying on epoxies for structural strength is on the same level as putting square windows in the DeHavilland Comet... something nobody really thought much of until after the problems became too clear to ignore. These days, the skin panels are designed to be held together to the plane by rivets, and the fay surfaces will be sealed with polysulfides which are soft and rubbery enough to survive cycling, won't revert in humidity, and are meant entirely to seal the joint and not expected to lend any structural integrity.
I remember the high number of cycles of pressurization being an issue. Thanks for the additional info.
I read once a long time ago about how Fokker Friendships used epoxy but folded the butt section around a second piece of metal (or an interlock with the next sheet). It was unusual at the time but the insurers eventually liked it. I've always wondered about the actual engineering details. Off to G**g** now. I'm old enough to have clocked up a few miles in Friendships and used to enjoy the milk runs with lots of hops between cities. Flying lower is much more interesting but bumpy.
Im so glad you explained - i have to fly next week.
As I understand it, the question regarding "square windows in the DeHavilland Comet" has become misunderstood over time. The cabin windows were not entirely square, and in fact had rounded edges - where the misunderstanding comes in is that the fatigue cracks in the case of G-ALYP began at the "windows" surrounding the ADF aerials in the roof of the aircraft - these "windows" consisted of opaque fibreglass rather than glass. The original specification called for these window frames to be bonded in, but at some point a decision was taken to rivet them as well (presumably in an attempt to reinforce structural integrity). This was a late modification to the construction process, and does not appear to have been well thought through, because punch-riveting was used as opposed to drill-riveting. The problem with punch-riveting is that the process distorts the skin as the rivet is punched through, and this distortion is prone to cracking - the investigators came to the conclusion that this was very likely to have been the origin of the cracks which fatigue made worse in a much shorter number of cycles than would have been the case had the ADF windows been bonded in as per the original spec.
The switch from rounded rectangular windows to oval windows in the cabin was the result of wanting to eliminate every possible source of cracking origins in order to restore public confidence in the Comet 4 - in fact the "tear strips" mentioned in this video were not only adopted by Boeing for the 707 and later types, but also by De Havilland in the Comet 4. Every subsequent British jetliner design was, if anything, over-engineered in terms of structural integrity - which came with minor, but noticeable weight and performance penalties.
The Yankee (later Grumman) AA-1 series of light aircraft were manufactured by bonding (glueing) the aluminium panels together, with minimal rivetting. De-bonding accurred in service, requiring in-service rivetting.

I didn't notice you mentioning the exceptionally high number of landing cycles per hour on these interisland flights. I grew up in Hawaii and remember this incident very clearly. Aloha took a lot of heat, but I remember one of the things that propagated through all carriers was that they needed to do certain maintenance and inspections based on landing cycles instead of purely by flight hours.
1 - high cycles for relatively few flight hours
2 - warm salty humid environment to speed corrosion
Is that because lots of short cycles contain more take offs and landings, so a long flight pattern will be a lot less stressful but show the same amount of flight hours?
@@dionlindsay2 Well it actually depends on which part you are talking about but for the skin of the aircraft yes the cycles of expansion and contraction of the fuselage with each pressurization is the dominant factor. In this regard, it is similar to how freeze-thaw cycles need to be taken into account when calculating inspection intervals for critical structures on the ground, water getting in to and then cyclically expanding and contracting with the freeze-thaw has a similar effect of applying pressure to any weak point that does develop massively accelerating the propagation of cracks. The main difference is that water freezing pushes the parts of the crack apart whereas in pressure vessels the pressure differential pulls the crack apart but either way repeatedly jacking the crack open causes the stress concentrations at the end of the crack cause it to grow at the ends until the part fails or properly conducted inspections detect and stop the growth of the cracks.
@@seraphina985 Wow, thanks for such a detailed answer. I had just assumed the take off and landing bits were hardest on engines. But expansion and contraction I get (I was a duffer at sciences but I remember teachers getting me to understand a bit about the coefficient of linear expansion). Thanks for the friendly answer :-)
@@dionlindsay2 Well the cause of the expansion is different in the case of the hoop stress on a pressure vessel but the vessel does indeed expand and contract a little. There is no such thing as a truly rigid body all materials are at least somewhat flexible and will deform to some degree when subjected to variable loads of any kind. Not usually enough to be perceptible but it is enough to slowly wear on the internal structure of the material over time. For a tubular pressure vessel like an aircraft fuselage or say a pressurized pipeline you have stress trying to pull it apart in every direction which does cause the radius to expand slightly and also the length to be stretched a little (hoop stress and longitudinal stress respectively). Over time this is what leads cracks to begin to develop at any stress concentration points and expand from there (Rivets or any discontinuity in the material properties of the structure ie windows in an aircraft or welds between sections of a pipe or whatever.
Back when this happened a friend of mine was one of the investigators he said the only thing that held that plane together when it landed where the strips of metal that the seats were bolted to otherwise it would have folded up when it came in contact with the runway
The normally heavy wind in the valley that Maui airport sits in, also died right as they started their approach. They got very lucky
The underbody skin also helped. The front of the aircraft is the least stressed part of the airframe. If this had happened between the wings and the tailplane, your scenario
would probably have come to pass-- while airborne.
I was a 727-200 captain at the time of this incident and remember that my employer was very quick to issue reassurances that our fleet consisted of the later, differently constructed. model. I had forgotten this all but now I'm off to Google to find what the differences were. You can retire from flying, but you can't stop being a pilot I guess,
Can you imagine the heartbreak from the flight crew when they have evacuated and they speak to the crew? “Where’s CB?”
RIP Ms Lansing x
Such a shame, she was simply in the wrong place at the wrong time. Rest in peace indeed.
Excellent explanation of this incident. I remember it clearly. Having flown on similar flights in Hawaii in the mid seventies I know that the Aloha and Hawaiian Airlines aircraft had a far greater number of cycles than most other airlines. The pilot and first officer did a remarkable job getting this plane down onto the runway. Thank you for explaining this incident so thoroughly.
It's amazing how many of these tragedies are mitigated by good pilots.
Your dogs, man... I'm trying to focus but they're stealing the show, especially the white one.
This is getting out of hand, now there are 2 of them...
@@SeriousApache true. And both are just sleeping. Must be quite boring to be a dog
I know they look so comfy and cute.
KazakhToon I feel vindicated reading your comment/this thread...in fact, I think it would be a good idea for them to be fixed in the corner of the screen throughout the video. They're the cutest little dogs.💗🐕🐕
I have white exactly like yours, 14 years old now. Very smart dog.
*A good buddy of mine was on this flight (YEARS before I ever knew him) as an almost-tween. He was in the row (I believe port side) one ahead of the over-wing escape windows. It would be many years b4 I ever met him, but alas, I never would have but for some great airmanship by the crew.*
I recommend that if passengers see something of concern, they should report it to the pilot or co-pilot. Several years ago we were on a flight from Honolulu to Lihue, Kaui, when I informed the flight attendant that there was whistling sound coming from one of the windows. The flight attendant told me it was nothing to be concerned about but I knew that wasn't correct & I insisted on speaking to the pilot or co-pilot. He turned white when I informed him, they lowered the altitude the plane was flying at, and they grounded the plane until it could be repaired. I wish I could say that was the only time that happened but it happened again on a flight from Edmonton to Calgary which was going to continue on to Toronto as its last leg of the flight. I got the same response from the flight crew but I informed them that rapid decompression could occur & asked to speak to the pilot or co-pilot. Thankfully the plane was then grounded in Calgary for repairs. I shudder to think what could have happened if I hadn't insisted on speaking to the pilots/co-pilots as passengers could have been in danger of being sucked out of the plane if the window blew out & rapid decompression had occurred. I knew about rapid decompression from my training to be a flight attendant but went to university instead rather than be a flight attendant. (Sharen)
Damn !
I call bs.
@@daren32909 Your call is wrong. It's the truth. I was there with my wife in Hawaii when this happened.
@@daren32909 Agreed.
@@daren32909 i don't understand why people like you and @Julia always 'call bs' when there's so much detail in a comment. You think that people who experience things in real life don't use the internet and comment on stuff? Or is there a group of people on the internet just going around calling everything bs as a hobby?
I've never heard such a detailed analysis of this incident! But it was miraculous that the pilots and crew were able to safely land the aircraft and save so many lives. Thank you for making this video!
and I think I'm gonna keep my setbelt fastened unless nature calls from now on
Ask any flight attendant or pilot. We “never” take our seat belts off when flying as passengers.
@@linarm1 well I dont really take it off because I'm lazy.
I'm never getting on a aircraft again.
@@therugburnz cars are even worse!
@@archmagos1436 Yeah, driving your car between the Hawaiian Islands is very dangerous.
What a heroic flight crew. This is the type of crew you pray you get every time you get on board an airplane.
I remember seeing this on the news when it happened and was flabbergasted that the aircraft could even fly in that condition, and could only imagine the horror of the passengers, particularly those in the open.
It is truly amazing. Bless all involved.
During an interview, passenger Gayle Yamamoto told investigators that she had noticed a crack in the fuselage upon boarding, but did not notify anyone
If I saw that I WOULD NOT get on that aircraft and tell the people

@@izakomandaz2895 There is no reason to use caps for that. Use your vocabulary instead.

One of your best videos, Petter. I remember very well the accident when it was broadcasted on the news and I felt (and still feel) extremely sorry for the poor lady who lost her life, but also admired the pilots' skills that allowed to land the plane safely. BUT overall I like your pragmatic and systematic approach, your digging into the crucial facts, avoiding any sensationalism; and I love the way you present the conclusions and the lessons learnt. Well done!
so often in these stories the flight attendants are the unsung heros, its really amazing even after that whole roof was gone she still risked her life to crawl around and comfort passangers.
One of my friends is ex-crew and as far as they are concerned, once they are in the air, it's their plane and they will protect it and everyone in it until it's back on the ground. (so don't annoy them when you're on board because they are your friends!).
I’d love to show this and the Hudson video (in particular) to all those who make derogatory comments about flight attendants. Thanks for another excellent video.
This man is a great host... very informative and sound experience as a 737-pilot. I'm a Marine Corps combat-veteran--I flew the F-4 Phantom "wild weasel" until a career-ending combat injury during the Gulf War. Some of my greatest memories were early morning training sorties out of MCAS El Toro California. I could pull the nose up, the elevators (vertical stabilizer) would move upward, forcing my climb attitude for a quick 600 knot push to the ceiling @ 20,000 feet. In seconds I could level-out and watch the sun rise before the rest of the West Coast could... It was akin to walking on water with Jesus Himself. "MENTOUR PILOT" brings back great memories, and those of tragic accidents for which I witnessed in both training and combat actions, that causes me to miss my days of flying Mach II through the desert and over the Pacific. Semper Fi!
This happened the same year my wife and I got married (actually about 5 months before) we honeymooned in Hawaii and still took 737s to fly from one island to the other but kept our seat belts on the WHOLE time! Metal fatigue salt air environment. I guess metal fatigue notwithstanding Boeing built a pretty solid plane!
I flew on that very aircraft less than a year before this incident going from Honolulu to Lihue on Kauai, 2nd. May 1987.
Just like I was driving on the I35 bridge over the Mississippi River in Minneapolis two weeks before it collapsed in 2007. I was also on a plane flying from Philadelphia to LA on 9/11/01, but it wasn't one of the ones that went down. Sometimes we're luckier than we realize.
Earthworms Crawl Yes indeed.
My oldest was born the very day you flew on that plane. Clearly an auspicious date for both of us
@@trueriver1950 You just wanted to write a sentence with the word (auspicious) in it.
Sure you did.
I love your channel. I am a retired professional pilot and I enjoy your reports and videos immensely. Keep up the good work.
I love this series of videos, very well done and very informative. Please consider doing one on PSA flight 182 which collided mid air with a Cessna over San Diego in 1978 (which I remember vividly). I believe at that time it was one of the worst air disasters in the US.
Keep up the great work!
I want to thank you for how you present these cases and walk us through not only what happened, but why, and in such a way that the images you use in the video serve to accentuate what you are talking about instead of you relying upon them completely. I listen to these primarily while I'm working outside, and your ability to verbally paint a picture while maintaining calm professionalism is greatly appreciated. Thank you!
Amazing that this plane stayed together through all that. The engineering of planes these days, the skills of the cockpit crew and cabin crew, , and some luck made this much better than it should have been. Sad there was loss of life and the fact that it could have been worse doesn't change the fact that she's gone but thankfully they were able to minimize loss of life as much as they did.
I loved being updated on this particular accident. I was working as a flight attendant with TWA at the time. Hired in 1974 as one of the few male F/A''s in the at time. You've added great depth to this incident...Thank you!
I've just noticed Mentour's sofa cushions are in a navigation lights configuration, red on the left, green on the right. If his wife or kids swaps them round, would he face away from the camera when doing these videos?
Red sock left foot, green sock right foot.
Lol
I can just hear it in Kennedy Steve's voice: "I suggest you face towards the camera, the audience doesn't like it when you face away from them!"
Red, right, return. They are correct if he's coming towards us on his flying couch
very sleepy flight crew, too! 🐶
It's incredible the pilots were able to land this plane without suffering further structural compromise.
I remember when this happened and the fact that the pilots were able to safely land and with only one fatality is an amazing feat. CB R. I. P.
Wow almost 90,000 cycles on the airframe seems like a lot indeed
Yep, far more than Boeing had anticipated
It’s a function of the locale. Up until March, I used to fly between Honolulu to Kahului on Maui fairly regularly. From the time where the aircraft pushes back from the gate ‘til the point where you get off on the other side is about 45 minutes at most. Each interisland flight that comes in disgorges its passengers, and then nearly immediately, boarding starts for the next leg. Between HNL and OGG, the cycle time is a little more than an hour, and under normal circumstances, flights run from about 5:30 am ‘til about 10pm, so it’s possible an aircraft can do 10 cycles a day on this particular route. I don’t know how long each aircraft spends in maintenance, but it can’t be that long since this aircraft was built in 1969 and failed nearly 30 years later, so call availability 300+ days a year.
I’m from half a world away, but my wife is from here and she remembers the coverage on TV and in the papers at the time.
@@MentourPilot I wish you put more emphasis in your video about the significant about the discovery of cycles needing to be separately tracked from flight hours; if I'm not mistaken, the pressurization and depressurisation cycle is the most damaging part of an aircraft flight, in terms of metal fatigue. I would imagine that long-haul aircraft would actually have exceptionally long lives in comparison, because even though they traditionally would have significantly more flight hours, the amount of metal fatigue the body experiences would be much lower.
Actually, speaking of air accidents, I would love to see do a video on a flight where the pilots of an asian 747 got disoriented, fell out of the sky, accelerated beyond design limits, until they saved it at the very last minute, and landed safely. Apparently it even ripped parts of the tail off from the velocity. I forget what the flight was called.
The reason I'm bringing it up is because this story reminded me of a very weird quirk that was permanently etched into this particular 747 for the rest of its service life: the wings had a permanent upward bend of about 1 degree. 😅 I would be curious as to how much that would affect the plant handling going forward.
On the day of the accident there was only one other 737 in the world with more cycles than Aloha 243.
@@TheEDFLegacy It was a 747 belonging to a Japanese airline. One engine flamed out at high altitude and, instead of descending to a lower flight level to restart it (where the air is denser), the crew tried a high altitude restart. Lacking adequate thrust, the plane banked and entered a dive.
As a non-destructive testing (NDT) technician, part of my job is using testing methods (ultrasonic testing, for instance) to seek and report those cracks in a piece of metal of other material, in order to prevent this sort of things from happening. This example of flight 243 was given to us during the training, and this video made it all very interesting and "real". Thanks!
What about new materials such ás carbon and fiberglass type skin? Does ultra sound work on them?
@@sharoncassell9358 Oh yes, absolutely! Actually I only work on composites. Those are laminated (several sheets of fabric on top of each other), so you very much see each layer and if they bond well together (disbondings are bad and detected with ultrasound). You can also see porosity and foreign objects (a chunk of paper or plastic, for instance).
Some techniques are not possible in layered fabric like composites (such as using transverse waves), but those are not really required with composites since we mainly use them when testing metallic solderings.
I mainly work on carbon fiber, glassfiber, and kevlar-fiber. Each one has is own specificities and some are more easy to test than others (glassfiber is very absorband, so the wave rapidly decreases when the material gets thick), but otherwise it’s totally possible and also widely used :)
Big thanks to all the maintenance crews who work hard to find critical issues like this and have prevented countless potential accidents.
Ahhh... the wonderful story of Aloha Airlines. Although it's tempting to make a quip about fresh air, it is tragic that someone died during this flight. That being said, I am very happy that it led to some very meaningful and impactful changes that are still felt to this day.
Thanks Mentour! I hope you cover the Comet at some point, as there is a LOT of crossover with this particular incident.
I’ve revisited this video and am touched once again by the heroic dedication of the whole team side note: I miss the poodles on your newer videos.
If watching videos on crashes makes you nervous, remember this: every time an airplane crashes, chances are, your next flight just got at least a little safer.
Exactly !! Like the race car drivers (test dummies) that walk away from horrific crashes. Or football players who have knees destroyed but come back to play again !! Cars get safer and surgeons learn more. We owe them.
It's also worth noting that air travel is the safest form of transport. You're far more likely to get injured or killed driving your car to work.
It depends. The first crash of the 737 MAX didn't improve safety... they had to wait for the second one.
Actually, I've found comfort in it, not that I was ever particularly scared of flying before. I now know which bits of the airplane we can have fail and still make it safely to the ground, or, if not safely, at least have a possibility of surviving.
Mommy says, "Every time a plane crashes, an angel gets his wings..." ...and a pilot looses theirs."
I am a currious tech guy and I am following ACI for years. Your videos are extremely good! I deeply appreciate the effort! Greetings from Bulgaria :)
I can be a nervous plane passenger at times, but I think the soothing calm demeanour of your presentation, the way you use these accounts as a way to show how things have improved, or things to watch out for, and those adorably floppy dogs lying so peacefully besides you as you go through these difficult stories...somehow all of this makes up up a very soothing and calming environment, that I will probably think of the next time i find myself being nervous on a plane.
This new section of incidents and accidents is becoming the best of the whole channel. Good job Mentour.
An absolutely incredible story! I can't believe the pilots managed to get the plane down in those conditions, and that the flight attendants (RIP Clarabelle Lansing) were able to keep the cabin calm. Puts my faith in pilots after a few scary stories of their negligence.
Even dogs fell in sleep. This is unintensional ASMR video.
I was ticketed on that very flight! The last moment one of my instructors at UHH wouldn't let me miss a class so I didn't go to HNL to go clubbing.
I normally sat up front and knew Mimi casually. Such a tragedy but kudos to the crew. I've wondered how I would have reacted had I not missed that flight.
What it did do was to peak my already interest in aviation and ended up going to a professional pilots school after UHH and worked in aviation my whole career. Very rewarding, but be prepared for industry ups and downs.
Listen to what is said here as you need to be a pilot first, equipment operator second.

@@pasoundman Thank you for the grammar correction. I am sure that no one could understand what was written without your clarification.

Most engineers and stressmen know that you don't arrange rivet patterns in straight lines (because of the tendancy to 'tear along the line'). Adjacent holes should be off-set in good engineering practice - this has been known about since the early days of making boilers for steam engines !
The investigations that go into these incidents are crazy. The way they are able to track down the very thing that causes it.
