I'm a licensed professional civil engineer and I'd like to point out a couple of things. 1. The interior of commercial jet aircraft is not filled with oxygen; that would be hugely dangerous. That's exactly how 3 astronauts died on Apollo 1. The interiors of commercial jet aircraft are pressurized with ordinary air. Outside the air pressure is about 5.4 psi at 25,000 feet but with the compressed air it is designed such that it is maintained at the same air pressure as what exists at 8,000 feet or about 10.2 psi. What's important is what's called the partial pressure. Air is 20% oxygen so its partial pressure at sea level is 20% times 14.7 psi is 2.94 psi. That, or more, is what has to be maintained. 2. The air pressure does not concentrate at the corners of square windows. It is absolutely the same air pressure everywhere. Only the stresses, the forces, concentrate at the the corners of square windows.
I was thinking the same thing about the Oxygen comment. I'm not a civil engineer, but I have a degree in chemistry. Pure oxygen is highly flammable. A single spark and the plane would explode.
@@livetotell100 Oxygen, in itself, is not flammable. It is more of an oxidizer or accelerant...no?
@@kendallh9106 True. Oxygen itself doesn't catch fire. Fire needs oxygen to burn. So the more oxygen present, the easier materials will ignite a burn. Materials will burn hotter and faster when more than "normal" amounts of Oxygen is present. So the more Oxygen present, the more likely something will burn. A simple spark from loose electrical wires will do the trick. There are some studies that say static electricity can start a fire in an atmosphere with more than normal amounts of oxygen. So it's not a good idea to have an airplane that uses pure oxygen in the cabin or seating area. 🙂
I had to stop watching after about 3rd or 4th "pressurized oxygen"...
@@atlasz911same 😂
This video showed the helios crash in a brief timeline but that was a very tragic accident. The audio from the jet pilot that was next to the plane was so emotional. He was also reporting the flight attendant that was trying to save the plane but he woke up too late and the plane ran out of fuel and crashed. Hearing that pilots voice break while saying “mayday mayday mayday” is so heartbreaking
Absolutely agree especially since that male FA was training to become a pilot and may have been able to pull off a miracle and at least get the plane down.
Q❤😊
“The skies aren’t nearly as friendly as they seem” 😂 oh you guys
That incident with the pilot was so surreal when I heard about it! The fact that he survived that I and of itself is truly amazing! Then to hear that he was back flying in five months!!!
The co-pilot never flew again.
He should never have had to fly again. They should've paid him millions for their negligence
The copilot insisted the stewards hold onto what they were sure was the Captain's dead body because he was afraid it would hit the wing or engine, making things way worse. Otherwise they might have dropped a luving, partly conscious man to fall to his death. That would be a damned hard thing to live with.
Yeah it's amazing that he survived that at all... I don't think I would have survived..... there's no way. He's obviously a tough son of a gun
I admire the Campbell's perseverance to make their son's death at least has a meaning. And the Helios' fall is one of the saddest tragedy in aviation history, I can't imagine what horror Andreas had in his mind desperately trying to save that doomed flight... 😢 I guess everyone had gone into coma when the plane finally crashed... Truly saddening...
Yes the Campbells made sure their son didn't die in vain after it being swept under the rug. And with the Helios flight I only wish he succeeded in saving the plane.
Chances are that everyone on board had died before the plane ran out of fuel. The only reason the male flight attendant survived as long as he did was the oxygen tank. After this tragedy, pilots are now required to put on their oxygen masks when they encounter a warning like this. If the pilots would have went on oxygen, this could have been avoided. In the full investigation of this, there was a warning before they took off and the pilots didn't believe it was a real problem but they thought it was a bad sensor.
@@Jman531 Helios wasn't the only one. There was a private jet that had a decompression that killed a pro golfer and some of his associates on his way to Texas I beleive it was. Jet scrambled but they couldn't see inside the plane at all. The windows iced up.
@@JadyraYou're right. Payne Stewart, it's unknown still why his flight crashed and the pressurization issue as far as I know
the last statement was chilling........ ''it takes some place we were never meant to be''
John Nance has such a peculiar voice. Almost like a product of black & white television, back in the day. Love it when he narrates investigations.
Sounds a bit like James Stewart.
He definitely has a Jimmy Stewart vibe
4 scenes of air disaster

18:23 2. British Airways Flight 5390 🇬🇧
27:35 3. United Airlines Flight 811 🇺🇸
38:05 and 4. Helios Airways Flight 522 🇬🇷
Thx
Travel in Australia. Not one single commercial flight fatality ever. QANTAS never lost a plane & the two major scares it's had, the pilots have been heroic in landing their damaged planes - zero deaths. Ever.
Not going to lie, when they started talking about doors, I was expecting American Airlines flight 96.
@@lex_hayes you may have hexed QANTAS!😊
@@ChancetheCanine lol. I'm here for future reference.
It's kinda weird watching this episode knowing that a commercial airliner just crashed in Nepal yesterday I believe. It will be very interesting to see how that happened. Sad. 😔💯🇺🇸
Watching the live stream from inside will give me nightmares
@@kyleball20 the fact that Sonu Jaiswal had no clue he was filming his last moments breaks my heart because you could see just how happy and carefree he was in the moments leading up the crash.
I just watched the news about the Nepal crash. I'm curious to see what cause the crash myself.
@@jacobewilliamson8086 i think it was a stall, there was a video released of that plane were the pane started to turn as it slowed down for landing
It was more a "Commuter" aircraft than "Commercial" aircraft.
Not a good outcome either way 😥
Unfortunately, people learn from their mistakes, but sometimes these mistakes are fatal mistakes! 😔😔😔
"We were pushing the frontier of knowledge", "Unfortunately, when you're pushing the envelope, stretching the boundaries of design ...." you are also pushing your luck.
It’s good that airlines were able to correct the problems but heartbreaking so many people lost their lives
Yeah. Unfortunately, we can only plan for what we know. Safety rules are always written in the blood of those who didn't know what was dangerous.
Interesting to see that no one mentioned Frank Whittle's name, he actually mentioned his preoccupation about the square windows from the commet!!! But as usual no one listened until dessaster strikes.
*To all those that had their lives taken from them and their families only to make our lives safer flying down here.*
*Thank You.*
*🕊Rest In Peace🕊*

Tim’s survival. Is nothing short of a MIRACLE!!!❤❤❤❤❤ he could be my wingman ANYTIME😊😊😊😊😊
36:36 Lee Campbell would be so incredibly proud of his parents. What heroes. Perhaps unprecedented!
Are there any other NTSB investigations that were strongly influenced by a parallel civilian investigation like United 811?
Aloha was a miracle, the large chunk of aluminium that ripped away could have took the rudder off.
Crazy they showed a Alaskan plane and they just had a door plug pop off at 16000ft in January 2024 can’t wait for that documentary 😊
isnt the pressurization switch part of a pre flight check list? Strange they didnt mention the DC10 and its faulty cargo door and explosive decompression and lack of floor venting.
John Nance is a very articulate and a well spoken narrator. I like the deep sound of his voice.
Self-regulation of corporations is NEVER a good idea, especially since corporations and their leaders "have a fiduciary responsibility" only to investors and financial growth, and NOT to any human values such as minimizing suffering & death.
Time is money, the more time an airplane is grounded, the less money an airline makes. Airline makes money by having airplanes in flight. Which means the maintenance crew must work fast.
Commercial aircraft companies still have a pretty good track record overall.
It's not the safest form of transportation for nothing 🤗
It only works if everyone treats the value of life as infinite. Unfortunately they don't, meaning it can be more profitable to let people die.
It is clear that Maximizing profits by squeezing the last drop of blood from the workforce (increased burdens with a continually decreasing number of workers) is Not Compatible with a civilized society, because it destroys not only the affected workers and their loved ones, but by the impact of the destruction it also affects people in a larger area (e.g. air & water pollution). An ounce of prevention .... It's NOT a financial burden for corporations to pay 3 pairs of eyes and hands to make absolutely sure that the odds of accidents are as close to nil as possible. As a matter of fact, any reasonable decision maker Should see that the small loss of tripling personnel costs are Far Better Than CLEANUPS & DISABILITY & DEATH COMPENSATIONS!
@@romanregman1469 it gets even wilder when you consider money and wealth is literally arbitrary made up.
Excellent episode. Finally an episode with great sound and smooth video.
The Campbells are just amazing people
The Campbells traveled some 2,500 miles to get justice for their son.
I love that Dad. He figured everything out and took on the authorities.
The cause of the Helios airplane crash was not because the aircraft did not carry enough life-sustaining oxygen. It was because of the missed switch location during pre-flight check.
It was actually due to maintenance prior to Helios Airways Flight 522 that during one of those Maintenance tests, it involved the pressurization test. However, once that was done the maintenance engineers forgot to set the pressurization switch back to Automatic and was left in Manual.
@@RBMapleLeaf Exactly but no matter how the switch was left during the maintenance performed the previous evening, the preflight check list required that the pressurization switch be placed to the Auto position. That was missed during the preflight check by the pilots.
You pressurize with outside air (about 21% oxygen), and only carry small amounts of hazardous/flammable/explosive emergency oxygen in very carefully designed emergency systems.
The cause of the crash was it ran out of fuel.
@@stephenborntrager5367 Well that's what caused the crash the pilots were incapacitated long before that due to the wrong pressurization being set it was meant to be on Automatic but it was left on Manual after maintenance was done on the Helios Boeing 737. But as @goutvols103 said. One of the preflight checklist mentions for the pressurization to be correctly set.
I actually remember when this happened!! Couldn’t believe it! Still Sad the Flight Attendant was lost. 🙏💜
McDonnell Douglas had a problem with a cargo door that took down a couple of their planes too. One in the United States and one in France.
That Aloha flight is the most amazing. How that plane didn't tear apart is unbelievable. 😮
Wow, I LOVE YOUR CHANNEL!!
One video every day for one year 🤩🥳!
Your Playlists are very smart. Great Channel! Thank you so much for that!
✌️😁👍
Great video. Thank you for the upload😊
I’m impressed they manages to edit this video complication so we’ll. Since there taking multiple older past 40 minutes episodes reducing them to a very small percent of there total run time before they advance a head to the next segment.
Helios 522 wasn’t brought down by excess cabin pressure, but the lack of it…
I remember watching the Helios flight and how horrible that tragedy was
This was one of the better ones.I wish you would get some new .Getting pretty bad when i can close my eyes and just listen because ive seen it 50 times
I wish more movies would get part about oxygen correct. You hit it right on the nose about partial pressure. Life support was my job in the Navy, great comment.
The outward-opening cargo door was also a problem with a McDonnell-Douglas jet, except that design did not have electric latches. It seems like having all inward-opening doors including the cargo door would be much safer and prevent a lot of deaths.
Definitely, but try telling McDonnell-Douglas that. Oh, wait, you can't. They were *finally* bought out by Boeing in '96 after *decades* of bad designs.
Interesting collection of incidents. I’d watched each of them in Air crash investigation years ago. Tim Lancaster is always etched in my memory forever - what an unbelievable escape. The co pilot is the real hero of the flight and the third officer’s act of holding on to Tim’s legs is so heart warming. True rare heroes of the world.
Very intriguing n weird are tge multiple references to A320 thru the video !
Also have seen a lot if Greg Feity of NTSB during ACI days.
I don't know how Capt Lancaster flew again. I think you'd have to lock me up with intensive therapy just to lead a normal lifte again.
Wow i can't believe what i just watched
Outstanding plan but what took you so long to realize it was needed☺️
My husband's best friend was on this Aloha flight. At the time he was a little boy flying alone and he had taken off his seatbelt so when the roof pulled off he almost got sucked out. The only thing that saved him was that the guy next to him grabbed him and held onto him until they landed. He is now a married father of two but he remembers it as if it was yesterday. And yes he's not afraid to fly lol.
Cargo doors locking mechanism I would trust is solenoid rods coming out from fuselage on each side of the door controlled by 4 electrical circuits that are disenergised in locked position.
One thing that should be understood is
that when there's an explosive decompression, things aren't sucked out. Rather, they are blown out from the force of the air blowing out.
That guys lisp reminds me of my grandpa listening to AM radio in the car on long drives at night.
Somewhere I heard: “ Theory can only take us so far, the rest we learn by trail and error!” 🙏✌️🙏
I am addicted to this show lol
Thx I never seen this documentary also rip and first
This was absolutely a Miracle!!!! W O W !
“Most people take aviation for granted” not people who watched MayDay lol. We know.
so it's kinda a summarized reupload?
Unreal the pilots and passengers survived.
People notice when tv shows say things like "pressurized oxygen" but they dont bat an eye when they lie to them about every politician.
15:30 the design actually work: but a flight attendant was sucked into the small opening and blocked the air exit caused the whole section ripped apart.
Pressurization switch on Helios aircraft should have been on one or more check lists.
Imagine being an investigator and finding that switch in the debris in the manual position, knowing pretty much right then that you've found the answer.
I feel like a more visual alarm would have helped. Say, lighting up the pressurization switch. Nowadays they'd probably have a screen clearly read "loss of pressure".
There is an overhead panel check while the 737 is on stand or at the gate and there is another check that is performed passing through 10,000 feet. I believe there was confusion on the flight deck when the low pressurization horn sounded because it was the same alarm that was used for the take off config warning. Identical sounding. The crew of the helios flight thought the horn was sounding for an erroneous take off config warning and began contacting company to troubleshoot the issue. But as the aircraft continued to climb, hypoxia only amplified the confusion
Well I never want to fly again 😳
Funny thing: I watch these things before I fly; honestly, that’s how I know what seat to pick: one that gives me the best chance of survival if something happens.
Sit at the back
@@FleetpawSwiftback yeah, I love planes and aeration, so I have a tendency to watch this type of content a lot...and before I fly! 😬🤦
@@nadeembilal8507 good choice! 💖👍
They no longer believe it was 100% the fault of the square windows. There are a lot of videos on RUclips that explain this !
Amazing, it's a miracle
Amazing airplane to be able to safely land with such damage. Built Boeing tough.
It is tragic whenever lives are lost & the only compensation at all is that from an an honest determination to examine, learn & improve industry safety firstly before a need to apportion blame then at the least it is not a wholly negative event.
It must be an impartial honest examination always or we compromise air safety & public confidence at an exponential rate as the odds favour ongoing fatal disasters. Safety must ALWAYS supersede money or the lack of trust in airlines by the public will cost them much more money then following maintenance or crew regulations. The same applies to airliner manufacturers.
As an aviation enthusiast, ATPL licence holder, have flown the 747, 777, 757, A330, currently on the A350, also a test pilot for Lockheeds skunkworks, flew in ww1 and 2 and I'm only 22...I wholeheartedly agree with the business class menu.
Whoa, you're doing much more in life than what I am and I'm only 24!😂 Good on you!
3:46 Narrator: but less than 2 years after it's maiden flight the glittering jewel of British aviation disinterested in mid-air
Regarding outward opening cargo doors and their locking systems: The Boeing design and the McDonnell-Douglas design are so similar and just as bad. It seems like a better design would be long, thick rods that extend from the door into the surrounding walls. Why didn't they go with that?
All bets are off....you're now a test pilot! 😱😱😱
0:55 --- ,,Most people take aviation absolutely for granted''. Most people are absolutely reluctant about high altitudes. They know what they must from other people's experiences. But could be what is meant is that they should be involved more. In the end this is true, but it would not start with aviation. If not more basic things first, I also don't see they would be involved in aviation as they should.
Towards the end of the segment about "United 811", the cargo door latch, it appears to me that the family mentioed had more time, money, and resouces than the Safety Board.
The comet issue was officially attributed the radio attena "windows" not the actual windows. But the legend has stuck , no more square windows 😂
So, somebodies simply didn't bother to keep track of the number of flights (89 K) by the Aloha
aircraft.
Puddle Jumping commercial aircraft is pretty tough on them.
A 'Cycle' is a cycle.
Despite impressions, no Airbus A320s were harmed in the making of this documentary. 1: De Havilland Comet; 2: Boeing 737; 3: BAC 111; 4: Boeing 747; 5: Boeing 737
a world war 2 B17 is also capable of flying at those altitudes (35,000) (that's why the engines were turbo charged). it was extremely uncomfortable and dangerous. they were required to wear heated vests, heated gloves, oxygen at all times, and their hands would freeze to bare metal if they touched anything without gloves on. it's like minus 30 degrees.
it is not a pleasant enviroment at those altitudes without pressurization, and people do take it for granted because they have never been at that altitude without pressurization.
Tiny metal coffin.
Correct me if im wrong... but arent airbus aircraft made of carbon kevlar composites now which means no rivets?
Also, any attempt to make something "foolproof" is just an invitation to find a better grade of fools.
Yeah like "unsinkable"
I flew a minimum of twice a week to work for 4yrs. The Janet Flights were exciting days. -Ret USAF
The first thing you learn in the trucking industry is to never trust the work of a mechanic or engineer.
I see the same applies to the airline industry.
Not sure how you could be in a job like a maintenance engineer for a major airline and not verify every single part and piece before doing a thing. He just eyeballed whether or not something might fit...from his pile of leftovers. Was he advised to do that by corporate?
God Bless Tim Lancaster
I was watching this episode when the plane I was sitting in , was about take off 🌚🌚🌚. The guy on my left just took a glimpse at my phone and looked at me like 😳
On the Helios flight, as soon as the passenger masks dropped, the senior flight attendant should have been banging on the cockpit door and been on the handset to report the masks dropping. Flight crew resource training, not just cockpit crew.
I am expecting an episode of recent YETI-AIRLINES crash in Nepal
Atleast the helios flight attendance tried flying they should atleast have partial training incase pilot are unable to fly
Thank God for the Campbell's! I would hope my parents would do the same for me. Could do with out the gals screeching at 38:25
Hilo is pronounced heelow
I just want to say that Bill Waldock is rocking that mustache
Talk about admiring the view! But I think I would pass on being stuck outside of a window at 25,000 feet. Talk about brown trouser time. After such an experience I would never get into a jet plane again!!
The skin on a 737 is only .040 thick or 1 mm. There is a reinforcing doubler of .036 inch common to the stiffening stringers.
14:46 Oooooh! I see!💡 The Titanic method! Water tight compartments. It should only fill that compartment, or tear off that strip. Hmmm.🤔
This is a compilation of episodes already seen on RUclips.
Hi-Low airport 😂🤣😂🤣
I hate to point fingers but Helios failure was due to the lack of attention by the crew, not from the stated reason of the aircraft not carrying enough oxygen. Not only due to a missed switch in preflight but also the failure to recognize oxygen deprivation. Which to be totally fair, the later of the two could be from lack of training. Though that could be completely avoidable by simply putting in place a policy of dawning masks on an alert or whatnot.

Well this content is not made by the one who uploaded this on YT..
@@ingridakerblom7577 True, but it also is happening with content creators.
In this case I think it is. Isn't this the official channel of the same studio that makes the show? Or is it just a clever imitation?
6:17 the windows were not the source of the cracking of the Comet's fuselage skin. DISOBEYING THE DESIGN BY USING PUNCHED THROUGH RIVETS instead of drilling the holes, which caused stress cracks at the rivets. The square windows would not have caused the failures in many thousand pressurization cycles. The improperly installed rivets would have caused the aircraft to fail if they had used modern ovoid windows, it just might have taken another year.
We need to end the lying rumor. the windows were properly reinforced. Square windows in an airliner would be fine.
cabin pressurization switch?! Is that a checklist item? How about using a different alarm sound for different alarms! Some thing that cannot be confused! Why design a plane with bolts that differ only by a half a millimeter. That is nothing anyone would notice. What is the thinking there? Did the manufacturer really save that much money by using thinner bolts elsewhere than in the windshield frame? They should have designed it for the thicker bolts wherever the thinner bolts were specified in order to make things more uniform and interchangeable.
Diameter of the bolts was not the problem, it was the length! The short bolts didn't engage the lock nuts fully, bolts only had a few threads holding window to frame!
LOW OXYGEN WARNINGS
Low oxygen warnings should be distinct and crews should be prevented from turning them off.
When the brain is deprived of oxygen a person can feel euphoria. That’s why when you fly the flight attendants tell adults to put the oxygen masks on themselves first, then put masks on their children. If the adult begins to experience hypoxia they will feel so elated they won’t put a mask on their children and they will all pass out and then die from oxygen starvation.
I got to experience a simulated cabin blowout at 40,000 feet in a chamber at the Johnson Space Center. I was training to be a diver, suit subject and safety diver at NASA.
The exercise started by entering a hyperbaric chamber and sitting on one of the two sides. An instructor slid a small swivel desktop in front of me like the desktops in a classroom. Then the instructor put a piece of paper on the desk with a very simple test. It had questions like 2+2= , 3+4=, and so on. Then the instructor tells you to start answering the questions. (But at that moment a ‘simulated cabin blowout’ occurred and the chamber was free of all oxygen). There were no signs of a decompression.
I thought I was doing great on the test and then the next thing I realized was the instructor putting an oxygen mask over my nose and mouth. After a few moments of breathing pure oxygen I looked at the test. The first couple of questions I got correct. But all the rest were wrong. I put down 4-2=75, 2x5=139 or 3+7=giraffe and so on.
The euphoria I experienced led me to believe I was in total control of my mental facilities but I wasn’t. It was a very valuable lesson.
The feeling of hypoxia effects is the same as the euphoric feelings people get during ‘near death experiences’ is simply oxygen deprivation. It has nothing to do with the supernatural or a god. It’s simply your brain being starved of oxygen.
You’d think in such expensive aircraft there would be an immediate alarm and voice command to warn passengers and crew to immediate don oxygen masks when there is a rapid decompression. It would be an inexpensive modification compared to the cost of multimillion dollar aircraft and the lives of all on board.
Why do you keep uploading the same videos again and again
i think im not the only one who have the feeling that video maker is paid by Airbus lool anyway great work
Why do they keep calling it pressurized oxygen? It's pressurized air that is 21 % oxygen! As far as I'm concerned, it could be called pressurized nitrogen because the majority (78 %) of it is nitrogen.
I hope he means "pressurized air" pure pressurized oxygen is dangerous
