On the 12th of June, 1972 , American Airlines flight 96, a McDonnel Douglas DC10-10, suffered a sudden depressurisation when its rear cargo-door detached inflight over Windsor, Ontario.
This explosive failure partly disabled the aircrafts flight controls as well as one engine. The Pilots and Cabin-crew managed to get the stricken aircraft down safely on the ground, saving everybody onboard.
In this episode I will explain what happened and WHY.

Dude i am absolutely amazed with your channel and am subscribed as an aviation enthusiast
and i did not think to renew my NordVPN sub(with their renewal price for 1 year), but with your code i did not even think, just followed the link and i am grateful
Always amazed with this series, your explanations are as always complete and meaningful.
Shout out to Kelsey @74 Gear , @Captain Joe and of course our smart and beautiful @DutchPilotGirl
You people make my aviation enthusiast day.
Hi how do you manage with so much happening at the same time and having so much constantly changing information
e.g. how do you manage the needs of flying the aircraft and ensuring its correctly configured alongside managing communication with ATC and managing interruptions either due to ATC or cabin crew
Can you cover Air Asia crash ?
You misspelled "heroes".
I use a VPN so I can watch BBC shows in the US.
My father was on AA Flight 96. He, and I assume, the other passengers, used to get a Christmas card from Capt. Bryce McCormack every year.
Aww - that's so heartwarming ❤️
Sandi Mims McConnell Kerth (who was one of the 2 flight attendants at the rear of the aircraft) started the student tour company I currently work for and she is a dear friend. She always tells me how much she loved and respected Captain McCormack for his professionalism and quick thinking on that day...she owes her life to him. When the explosive decompression occurred, she had to pull herself into one of the rear lavatories to avoid being pulled into the hole created when the floor collapsed beneath her.
@@kylecoleman1193 that's awesome, thank you both for sharing!
I figured it would go the other way around! But very nice. It was a great piece of flying. Way better than the Turkish DC-10 which later had the same issue :(
The Air Nauru incident over Brisbane Queensland Australia 737 -36N
That DC-10, man... So many accidents with so many different causes. I can't believe even a piece of metal from one ended up destroying and decommissioning the Concorde! What a cursed aircraft!!!!
Not wrong.. dang man i would have loved to hear & experience those engines. Alas, we can only dream :(
Absolutely crazy that the mandate to fix these problems on the DC-10 was reduced to a “service bulletin”, especially considering just 2 years later Turkish Air Flight 981 crashed because of the exact same cargo door problem. 346 people died.
Yes, that’s the next video in the series
The American way of handling problems. Look at Boing. Look at Tesla. Same principle 😢. Bought American kajaks. Some holes were not drilled centered. Support would not even acknowledge that this should be a problem...
Dunno about Tesla, but MDD bought Boeing, but took the Boeing name (this is why the current Boeing logo is what it is). They called it a merger, but MDD bosses were the ones in charge in the end, bringing their shit corporate culture. The other thing hurting Boeing were all the GE execs. But those guys are a cancer that has metastisized into many companies.
Moral of the story, if you have to brute force a latch. There's probably something wrong.
You have hit the nail on the head.
The baggage loader knew that their was a fault the moment that the door would not lock normally. That was the point that he should have summoned help, rather than after he had broken it.
While the maintenance engineer who he spoke to after the event should have known better, during his workshop duties, he may never have worked on the door, or even known fully how it worked.
Regarding the aircraft manufacturers, the door was badly designed and poorly tested under possible fault conditions. The situation regarding the cabin floor strength and /or no method of pressure equalisation was unbelievable, particularly since control cables and hydraulic pipework runs on the underside of the floor.
With that in mind and the fact that ANY depressurisation below OR ABOVE the floor could make the aircraft uncontrollable. the fleet should have been grounded immediately and a rapid modification made. Punching a row of vent holes may be aircraft engineering, but it is not rocket science. A small team of engineers could have carried out the work on one aircraft a day.
Instead, it took a crash and multiple fatalities to get them off their asses.
And if you have to brute force a pair of jeans you are in trouble too.
@@wilsjane he did summon help - he called the maintenace engineer.
Although, it's true, the fact that it could be done in a way that it looks like it worked is a bigger problem. The basis of aviation safety is that anyone can make mistake, anyone can be tired or whatever, but the system still needs to be working safely. What if that agent was strongman and could not feel the difference between forcing it or not? Maybe another recommendation would be to change training for them, or make a procedure for that event, like opening the door, and checking the mechanism. But, overall it's not fault of the agent or mechanic.
And, the biggest problem of all, was that the pressure valve in the door could be closed while the doors are not safely closed. And this contradicts the design requirement for that door. And the mechanic that was called, trusted that design.
@@syriuszb8611 As I said earlier, the pilots were not to blame.
The design of the door was poor, particularly since the electrical trip that showed that it was secure was in the wrong location and did not require correct and full engagement of the mechanism.
Most of the blame lies with the handler who forced the door. Even a child knows that if you force your toys they break.
I am sure that he could drink a beer without crushing the glass in his hand and manage to hug his girlfriend without breaking too many of her ribs. 😊
PS, Did you read my full account above, particularly regarding the events caused by differential pressures within the aircraft being possible after a fairly simple fault.
These stories sound much more relevant from you than from any TV show with tense music and sensational language. Thanks for doing this series!
Glad you find them interesting!
Totally agree. And they don't seem to be heavily scripted, just well-researched and then a natural presentation.
Yeah, as a person who isn't a huge fan of edutainment, finding channels like this is just great. I don't want to judge how people learn, but for some of us education IS entertaining, we don't need all the fake drama.
this is what happens when a non mechanicaly inclined person is charged with shuting the door. not to be confused with securing an double checkin that it is secure. his last job was prob. micky Ds. its not all his fault. something that he should have had some training instead of crame it an slam it. only good thing for him is he knows its not his fault. i secured it. this is where mech. inclined comes in. if he had that he would have known something is not rite if you have to use your knee.most fault should be with builder.
It is a sad truth that "the media" have gotten used to hype-hype-HYPE-OVERHYPE everything ... because they are competing against "the other channels". Thus the use of the strongest and most extreme superlative / language is used.
This is part of the reason why todays population has lost all sense of MODERATION and has instead become extreme in their positions.
A British friend of mine worked for McDonnell Douglas for 17 years. He said the problems started when they stopped listening to engineers and let accountants drive the engineering. Friend was pretty senior, in charge of 400 staff.
Boeing is the new MD.
@@srinitaaigaura Yes, the problems started with the Boeing takeover.
Accountants having more say than engineers? That seems to be a precursor to a lot of disasters.
@@YourGranIsBigMad When engineers are told to find cheaper solutions rather than the best solutions then disaster is inevitable. The real solution is to work hard to make the best solution cheaper, but time constraints make this difficult when targets are fixed.
We said MDC took over Boeing with Boeing's money.
The craziest thing about this accident is the fact that it could've been avoided entirely if the mechanic had taken the issue seriously
One of my tech teachers had this saying "you can force it in wrong, but you can't put it in wrong" (referring to computer parts that are plugged into the motherboard). I believe that it equally applies here. Having to force the door closed should have been a huge red flag. But I'm glad that everyone got off the plane alive.
Which is why someone was asked to look at it. Who made a bad assumption about it being OK :-(
Can you imagine the engineer after hearing what happened might have been sick from thinking about what could have happened ?
That's what she said
Pin headers don't care
Your teacher never worked on the DEC PDP 11-70
Watch a video of pilots putting PC-12 gear down...
I knew Captain McCormick and had the honor of flying First Officer for Captain Page Whitney many times on the 727 - both great individuals and fantastic pilots! Great factual video!
Glad you liked it!
My Dad knew Mc Cormick as well. My Dad was a check airman on the DC10 for many years.
What was Captain McCormick like?
This is much better than those Discovery Channel’s documentary. Concise, informative, straight to the point, most of all, no repeating the same sentence over and over again for 1 hour.
Thank you.
I agree. I like the detailed technical information that you don't get on other documentaries which leave you guessing.
Always agree with these comments. The only thing missing is an interview or two; although those are so often edited to shreds too...
And only a couple of commercials!
I agree. Too many 'documentaries' are little more than acting gigs for C-level actors.
It’s a bit apples and oranges, but yeah, MP’s videos are five star quality.
I am amazed at how cool you pilots are when something catastrophic happens. I remember the woman pilot when the 737 engine exploded. She was so cool. She said as long as you have altitude and options things will be ok.
You posted earlier wondering if these types of videos are worthwhile. I’m a civil engineer in my “day job.” A lot of the safety developments, advancements in professional ethics, and discoveries about material/structural behavior, etc. have come from studying and discussing accidents and disasters. Some examples that immediately come to mind are the Kansas City Hyatt walkway collapse, the Challenger space shuttle explosion, the Tacoma Narrows Bridge failure, the Winter Park Florida sinkhole of 1981, and various dam failures. These and many more were all talked about at length during my university engineering courses.
Yeah safety measures/systems are written in blood, especially in aviation. It's unfortunate but it helped bring the industry grow and mature to be one of the safest modes of travel around
I have no idea why I love these aircraft accident/incident videos so much. I always love when a new one gets uploaded.
I've been addicted its seems so crazy that sometimes one mistake can cost so many lives
Glad to hear that.
@@2511jeremy The one that blew my mind was the air france airbus incident at the airshow. I couldn't belief only a few people were killed after I saw the video of the crash and huge explosion.
Wait.....this plane had a bar?
I like seeing how improvements are made based on past problems. It's so sad people lost their lives but learning from these horrible events and making plane travel so safe is admirable. Something good out of a horrible situation. Other industries can learn a great deal from aviation
Remember as a ramp agent having a problem with a DC10 cargo door which wouldn't latch. Engineer had to work on the door for about 30 minutes until the door closed correctly
Yep, this was a pretty widespread issue
@@MentourPilot am I correct in thinking that the Turkish DC10 crash in Paris was also a hold 5 cargo door failure?
Yeah, THAT is how things should be! Not like, "oh, whatever, this will be fine."
My Dad once told me, " If you have to force it - something's not right." Good advice for many things in life.
I’m a very, very nervous flyer who loves aviation. I’ve flown in gliders, I started my PPL, I’ve been flying since I was 2 months old. Then, out of nowhere, I developed an extreme phobia. I didn’t fly for 7 years. Now I can, and do, but I still need anti anxiety meds. These videos are incredibly helpful for me. I have a solid amateur knowledge of aviation, but seeing how even super unlikely events trigger re-engineering, re-training and new processes is incredibly reassuring. They’re also a fascinating watch! Thank you 😊
You're so brave! Well done! And all the best for the future!
Sounds similar to my experience. Was lucky enough to fly around the world when I was young, then suddenly developed a phobia of flying in my early 20s and didn't go on any flights for around 7 years as well. Finally got over it enough to start flying again, but I also generally take anti-anxiety medication during flights. The benefit is those drugs make me sleepy, so I can usually just pass out for most of the flight if it's not international or cross-country.
Right there with ya Eva...fascinated by aviation and love the beauty of aircraft,its history and stories... yet TERRIFIED to fly and when I do Dr. prescribes me 4 Valium(0.25mg) 2 for getting there,2 for flight back....glad I'm not alone! And this channel is great.
What meds help you? I have horrible flying anxiety. But I want to travel so bad 😔
how could you possibly fly a plane at only 2 months old?
24000 hours total flying time, what a legend!
Indeed!
Yeah, that’s 2 ¾ *_years_* in the air, 24/365. That’s a crazy amount!
@@MentourPilot One that would be kind of cool is the evolution of the 737 from the 100 model clear up to the max eight the difference in horsepower how long it took to get off the ground in the old one hundreds
@@Runoratsu - That's a hell of a shift.
Some say he never cashed in on a sick day
On March 3, 1974 Turkish Airlines Flight 981 crashed near Paris due to this cargo door, killing 346 people. So much for McDonald Douglas' concern with safety.
McDonald Douglas’ corporate culture took over Boeing after its purchase by Boeing - That’s what led to the whole MAX-8 fiasco.
@@TraditionalAnglican
there are strong parallels
Using the asymmetric reverse thrust after touchdown is a strategy I'd not heard of before. Brilliant!
I like to think the pilot monitoring was on the engines and could see what he had to do. Whatever the reason, it was brilliant in every sense.
Great video. Loved the engineering elements
Hi
Lol nice
This is so much more facts and less "crap" and "drama" than Mayday/Air crash investigation. I love it!
Awesome to hear!
What? You don't want to hear about the 5th birthday of the niece of some random woman on the flight? I'm shocked!
@@dobrowolsk 😂
I have to admit that I was missing the drama from other productions. Specially when I started watching this series because all mechanical and technical principles were explained at the beginning so I could figure out what will happen later on. BUT, once I got used to this concept, I started loving it a lot :D as you said, there are so much more facts and none of irrelevant stuff, so I'm eager to see more. Great job :)
I agree, but the "Mini Air crash investigation" channel is another story, they do a very good job too :)
I really love these ones where no-one gets killed... So maybe I'll skip next week. 😬 Just saw a documentary about United 811 which was similar to this one, but had a very different outcome. I actually cried. The associated Campbell family story was just too sad. Inspirational, but sad.
I understand that, but I will say it is an incredibly important (and sad) lesson on: the need for strong and independent regulation and oversight of the aviation industry; and the consequences of commercial considerations overriding safety ones. It is a lesson that sadly seemed to have been forgotten by the time of the 737-MAX.
One body was sucked into an engine too.
@@onceuponalittlecity It was never remembered in the first place. TK981 out of Orly, Paris crashed killing 346 people for the exact same reason just a few months later.
@@poruatokin Exactly. Flight 96 was lucky. Due to time/cost fixing the issue was not a priority, and so TK981 happened.
@@ruthmeow4262 capitalism looks great on paper, but in practice it always leads to stuff like this. companies out for profit will always prioritize cutting corners and shooting stuff under the rug rather than doing the spending money part that actually makes things safer
These case studies are much more interesting than those dramatised, hour long "documentaries"! Also they rarely cover near misses like this one.
Keep up the good content!
“If it bleeds, it leads! Gotta get them ratings!” yup.
Yeah I hate watching dramatizations
What with all the commercial breaks and the endless repetition, those hour long documentaries usually have about 10 minutes of actual content.
@@MeFreeBee I wish someone, preferably the copyright holder, would post an edited version without the repeats and perhaps even the emotional porn, leaving only the actual relevant parts.
I guess it would be possible to design an AI to automatically remove repetitive parts, as a plugin to RUclips. Just don't have it mangle music videos ;-)
Within your video, there is hidden a topic (from 6:51 or 7:35), that is very essential, if we talk about safety (no matter in what field in life, everywhere where people are dealing with technical or structural safety: The ramp service agent noticed the abnormality how the locking mechanism worked, because he had so MUCH DAILY experiences. But the procedure is - what is a structural problem - that a person with higher rank who is authorized to make decisions gets called and takes a second look at the problem and then decides.
But this prodecure excludes the psychology that the second person just feels more experienced but simply lacks "the flow" of the actual event, just joins the situation and there is a risk that he is with his thoughts at the place he was before or slightly doesn't unterstand the description of the first person and concentrates e.g. just only on what he sees but doesn't know how the latch felt, while it was moved so unusually etc., etc., little psychological momentums that makes the "expert" to the one with the worse decisions compared with the more simple worker who is from the beginning at the place of the problem.
This dilemma exists at sooooo many work places in the world and only exceptionally good procedures can deal with this psychological disadvantage, or if the second person is thinking in a VERY clear and rational way and says "stop" already only if he doubts.
Rarely is there any mention of the fantastic job the NTSB investigators preform. They are a master of all trades, from pilot to mechanical engineer. Airplanes have been made so much more safer due the diligence of these professional men and women.
And then have their recommendations ignored...
Basically men
I wish we could get this sort of attention in a few other industries.
You must be on drugs or extremely ignorant.
The NTSB makes dubious determinations quite often. They bury the truth and present erroneous conclusions. E.g. United Airlines Flight 811
@@HarryBalzak do you work for the FAA?
Kidding aside, the NTSB is on another level as far as diligence is concerned 99% of the time to get to the bottom of what causes a crash & make recommendations. And countless examples they do this & FAA ignores the safety recommendations. One of the key issues is NTSB can only make them but has no power to mandate/enforce them. That's up to the FAA. The result being many examples of great dislike between them.
The FAA had & imagine still has a shameful tendency to lean to airline interests over psgr safety.
As I recall from many yrs ago, a former high ranking FAA employee named I believe Mary Schiavo left for these reasons & wrote a book "Fly Blind Fly Safe" which goes deeply into this.
I am not familiar w/specifics of the flight mentioned so can't comment, but I do know thanks to the NTSB, flying wouldn't be nearly as safe as it is today & that's a fact. Flaws or no, they are the key agency that roots out causes & suggests preventive measures. And unfortunately being squashed out or influenced by FAA BS wouldn't surprise me. But carry on as you wish...
My favorite videos are about air incidents where everything ends up ok for the people onboard. I love to learn about how planes work and what can go wrong. But it is so depressing when people focus only on deadly incidents. Thank you for making these videos, they make me a much less anxious traveler and help a lot with quarantine boredom!
Yes, unfortunately next weeks video in the series about DC10 won’t be so positive 😢
@@MentourPilot The one where the real probable cause was the failure of the FAA to issue that AD, but it was not politically acceptable for the NTSB to say so?
@@phillee2814 The FAA wanted to issue an AD, but McDonnell Douglas persuaded them not to.
@@cr10001 Well, as the FAA has authority over MD and not the other way round, it was their failing, wasn't it?
Sadly, most of the safety rules we have were written in blood.
It makes me angry that the DC-10 had such safety problems because it was rushed into service and killed people. I flew DC-10s by choice when they first came out because it was a good plane for passengers. I didn't know the risks I was taking, especially because their where such better aircraft available (such as L-1011).
That crappy safety culture lives on in Boeing. It’s unfortunate that Lockheed didn’t prevailed in commercial aviation.
@@mangos2888 You can actually thank Boeing for that one. Lockheed needed the same Rolls engines that Boeing used in the 747, and with Rolls' bankruptcy at the time they were only willing to fulfill the 747 orders, since those were larger orders that got them more money.
The DC-10 was 💩
@@caracalfloppa4997 MD-11 has entered the chat
Wasn't the L-1011 the aircraft that had a tendency to lose its entire tail section if one of the bolts was over torqued?
I love that you always acknowledge the work of the cabin crew in these videos :) Another great one!
when you look multiple investigation series, you start to see patterns. Peter here for Mentour Pilots is a crew resource management guy. For him in his professional role and understanding, everything is solved by team work. Other channels focus more on the avionic and praise airman ship in controlling the plane. Off-course, both points of view are valid as airman ship is required to control the plane in such a situation, but it is resource management to decide what the goals are, what tasks derive from those goals and who takes on what tasks. I think this is also important in training: One instructor thinks of a captain of being primarily the guy that brings the plane down safely. An other instructor might think of a captain as a manager and mentor of his team. I work no where near avionics, but thinking "what would Peter do in such a situation?" can deliver a valuable idea on how to tackle an issue differently.

Please don't be offended, but "airmanship" is one word.

@@K1OIK He's posted several where overconfidence by the crew or bad communication between them end up causing accidents, and he rightly calls them out on those occasions.
An average day becomes absolutely fantastic when Mentour uploads 😀
Awww, thank you
Everyone safe, wonderful outcome. Your presentation was clear and understandable minimizing confusion. My granddaughter is studying to be an engineer at Purdue and was impressed how you took your time explaining the mechanism used in securing the cargo door for flight. When she was watching your video she was at a point during one of her engineering classes where she was required to explain an engineering complexity to an English major. She listened to how you spoke during your video three times and told me how she learn a few useful important points that she incorporated in her homework assignment. She wants to thank you and hopes you feel good educating the public in general.
It is obvious why we love Mentour pilot docos. They are not melodramatic. They are factual. They are not biased in the form of sponsors and conflicts of interest. And they are straight to the point. Mentour pilot fills a huge void created by main stream media because almost everyone has had a guts full of virtue signalling and global agendas.
Thank you, that’s what I’m trying to do
I'm rather addicted to this series. I'm not a nervous flier - I realise that air accidents are rare events statistically; just rather messy when they occur. I think your explanations are even-handed and detailed enough without going overboard. Love your presentation style, too. Are you flying professionally again yet?
At that time, 49 years ago, air crashes weren't all that rare. Stressful time.
There are so many that are shown on other channels where it would be great to hear a pilot’s perspective; British Airtours where the windscreen is sucked out, leaving the F/O to do the emergency, flying, radio, landing… with no time to do checklists or calculate landing or have any landing sheets. Also Flash Air, the somatosensory illusion and cockpit zero CRM. It’s just weird how simple it seems.
Your production values have taken a giant leap forward in the last few months. Love the mishap series.
Glad to hear that
@@MentourPilot Agreed.
And especially the neat new end bit in this episode. Nice work.
Mentour is MARVELlous at keeping his viewers engaged till the end.
Petter, my highest compliments. I have been a bone marrow transplant RN for many years, and I've also had a lifelong interest in aviation matters (though I am not a licensed pilot). My specialty requires ICU nursing skills as well as oncology nursing skills. It also involves dealing with unexpected emergency situations on a regular basis. Nurses have no idea how much our profession has to do with piloting concepts. There is so much in common: CRM, just culture, safety mindset, design of procedures, etc, etc. But most of all, you have become my role model for leadership training. As senior staff, my patients and my younger colleagues all look to me for leadership and support. Watching your channel regularly helps me stay sharp and helps me avoid leaning on long experience and just going on "autopilot". As for my younger nurses (esp in ICU environments), you should see the light go on when I explain PIOSEE as a tool they can lean on in a stressful situation. Many thanks to you, Petter.
I lived in rural Essex County, just outside of Windsor Ontario Canada and only a few miles from where this happened.
I still remember the T.V. news and newspaper reports. A coffin (containing a body) fell out of the cargo compartment of this aircraft and fell onto local farmland. The farmer who found the coffin said he first thought it was someone playing a prank with an old coffin and a mannequin.
I love all your videos but these case studies have become some of my favorites.
Awesome!
is it just me or is this series better than those national geographic aircrash investigation / mayday episodes
Less drama and greater respect for the victims. It is very well done. Amazing rely how a youtuber can do better then a massive network glob.
@@Stettafire Mentour is aiming at a relatively educated audience, not a TV audience with a three-minute attention span and a two-digit IQ who need drama!!! every 30 seconds or they'll switch to the football...
Wow, such a great and detailed investigation!
I remember reading about these cargo door issues of DC-10 and I've caught myself thinking "Is this the first DC-10 accident with the door? Because the other one later had been fatal." And here comes the darkened outro...
If my memory serves me well, there was a deal between NTSB and McDonnel Douglas, so that either the former never issued the bulletin or the latter never done any construction changes thinking that it's not a big deal until the next incident had come killing everyone on board of another DC-10. It was quite weird for me to learn about such a terrible act of carelessness and, at some point, manufacturer's greed.
It would seem regulators and safety organisations don't take safety seriously. Why weren't the faults on this aircraft spotted before it was ever allowed to fly ?
Yes the Turkish Airlines flight 981 3rd march 1974 348 died. This is the best part of 2 years later... The FAA failed to make the modifications mandatary. The "cosy" relationship between FAA and US plane manufacturers seem to have a long history?
@@millomweb They don't take safety seriously until AFTER enough passengers perish. It's the tombstone mentality.
@Robostomp The deal was between the FAA and MD. The FAA didn't issue the bulletin. The NTSB issued the bulletin twice.
@@mach6893 Absolutely true - one or two killed in an incident changes nothing.
@@millomweb Flight 96 was the aviation gods telling the FAA and Douglas "This is your last warning!".
Please do a video on the Tenerife collision. Love your content :-)
Having watched all the Air Crash Investigation series, then found this channel recently, can say thank you very much for a great series, as commented previously, concise, informative, interesting, captivating in an intelligent way that the ACI series has to compensate for with dramatics.
Please bring us more relief from Lockdown and recreate the entire series for us to watch in this far superior way.
Thanks again!
The pilots acted really professionally. Especially notable is the FO's action of stopping reverse of the right engine, preventing the plane from leaving the runway.
I like the humble way that you phrased the words: "I hope that I have earned a subscription from you."
Your channel is very informative, interesting, and thorough. Thank you for all the effort you put in to making a channel worthy to subscribe to.
A truly "must read" book is "Destination Disaster" which goes into the Turkish airlines DC10 accident in complete detail as well as covering a full history of MacDonnel Douglas' other issues with the DC-8 and DC-6. A compelling read that does leave one hoping that the FAA have improved since then.
I love your 'investigation' videos. So professional and informative! Thanks!

Mentour, my dad is a retired flight test engineer with Northrup/Grumman. I turned him on to your videos knowing he would watch everyone of them. He is very impressed with how you articulate many of these complex topics. He thinks that you must have had some education in engineering on top of your flight training/education. He compares you to highly intellectual test pilots that he's worked with on a specific project that he was part of. Just wanted to pass that on.
Am I the only one looking forward to these superb videos every week? The quality is unmatched, captain! 🙌
I love this segment of your channel, Petter! Very informativ, great narrative, nicely illustrated - all in all: very well done!
Thank you! More to come.
You can really help me out by sharing your favorite episodes on social media
Although this was a terrifying incident, I love to hear stories like this where the pilots, cabin crew and air traffic controllers all worked so well together and also acting by themselves so well and turned this into a victory. I really makes me Feel good
I love this series. When I was in high school, I found a book in the library written by an NTSB air crash investigator. Fascinating stuff.
This is truly an unparalleled vision of professional aviation. Superb!
I been watching for a couple of years, because I'm facinated with aviation, but I got to say, you have been knocking it out of the park with this new investigation series. Love them.

Thank you for this video. There's more to this 'Windsor Incident': Captain McCormack had practiced in the simulator flying the DC10 using differential engine thrust in an exercised anticipation of control surface failure, which he used to save the aircraft here. Also, there was a 'gentleman's agreement' between the manufacturer and the FAA to not insist on an Airworthiness Directive, presumably to avoid harming the DC-10 sales prospects. The cargo door engineering had seen a lot of issues. It was made by a sub supplier and an internal engineer whistleblower had tried to raise design/ manufacturing concerns. As is now history, the TK981 disaster, 3 March 1974, was an accident waiting to happen. 'All these (cargo door flaws) were apparent at the time of the Windsor incident 21 months earlier, but owing to... regulatory nonfeasance, no efficacious corrective action was ever taken'. (From memory of the TK981 investigation report, sorry if I have not remembered 100%).
Sounds like it could be a case of the FAA being another regulatory agency that is captured by the industry itself, so it is the fox guarding the henhouse. Even if this was not the case, it is obvious that there was something fishy about a directive turning into a bulletin. The people involved in this should have been held accountable to the same problem causing mass loss of life 2 years later.
The sheer number of times that bits detaching from aircraft end up in an empty field seems beyond lucky to me.
The best is to hear about great airmanship, people saved and aviation made more secure for the future. Thank you for the important details in these topics!
So, if the sensors for the closed position would have been on the actual latches, as they are on th bow doors on my ship, this aircraft would never have taken to the skies? I feel safer and yet horrified as they deigned the warninglight to tell the position of the HANDLE and not the actual LATCH. 😯
Yes, that was rather daft.
When he showed the over-centre stop diagram I thought that would be an ideal place to put a little toggle switch...
So many aircraft companies have had real dum-dum moments over the years. Most recently Boeing, but it would be unfair to say that they were alone in it. MD had one job: if you want swing-out doors, make the door lock absolutely irrefutably tight. Nope, couldn't do it. I suspect 'expediency' (ie we had to rush it)...
Indeed. The whole latch mechanism was really poor design - far too Rube Goldberg with many possible failure points. It was not only unsafe, it was unnecessarily heavy and expensive too.
It's always a great day when Mentour Pilot uploads a new video!
🙏🙏
15:35 That, is some clear thinking right there.
This was a spectacular display of airmanship by the entire crew. The FO was brilliant to use the reverse thrust to keep the plane on the runway.
Indeed.They where “lucky“ to get that crippled plane down pretty safely. Turkish 981 unfortunately ended really tragic consequences... Lets wait next episode! Great done Mentour!
i am amazed mentour pilot did not mention this.
Was waiting for that. Pretty horrifying what happened to those poor people.
@@ursodermatt8809 he mention it just about the end of video
@@chimai001
yes you are correct, i just terminated the video when he was talking about the subscribing and notification , etc stuff.
Turkish 981 is part 2 of this video, a much more tragic story.
Tldr; they didn't really learn from this accident and then everyone (346 people) died when it happened again. (SB as opposed to an AD I guess). Worse still was the floor failure had been seen during ground tests prior to the DC10 entering service...
Was also going to mention this.
Peter, your videos explaining accidents and how each one of them helps improving the aviation safety are awesome. I'd like to suggest one about the Emirates 521 crash at DXB. Windshear, issues with fire fighting and the cabin crew doing an amazing job to save all the passangers lives in a problematic evacuation...
I'm really glad you continually give credit to the cabin crew. It's always easy to praise the flight crew when things like this happen, but without crowd control in the cabin, people who can provide the right atmosphere for maximizing survivability (making sure people are secure and braced, overseeing evacuation, keeping people as calm as possible), especially when the aircraft has been damaged, there would be many more deaths in events like these. The flight crew can handle the aircraft because the cabin crew is in charge of the passengers everyone is trying to keep alive. But also, the flight crew worked together wonderfully here. I admired the first officer's quick thinking when the plane started to veer off the runway after landing.
This serious of accidents is one of the most frustrating series I know about, because the second crash that's coming up was effectively caused by: "a gentleman's agreement between the head of the FAA, John H. Shaffer, and the head of McDonnell Douglas's aircraft division, Jackson McGowen." (Wikipedia) Basically McDonnell Douglas didn't want the negative press and the extra costs that came with an airworthiness directive. In other words the gentleman's agreement was that the planes wouldn't be grounded (which costs airlines a lot of money) but instead the upgrades would be put in place at the earliest convenience (usually when the aircraft is due for maintenance anyway). This also meant that the upgrades put in place weren't stringent enough = they were focused on being simple and fast to do instead of more complex (safer) and therefore taking the aircraft out of service for a longer time. The FAA generally really does a good job, but this is one of the black marks on it's history. :/
Really smart move to turn off the reverse thrust on one side to move the aircraft in the other direction, I doubt they'd trained that.
Just a quick note, this cargo door defect also caused a Turkish DC-10 with 346 passengers and crew to crash after taking off from Paris CDG airport on March 3, 1974
Maybe not worth doing another video on this, but Turkish Airlines Flight 981 (also a DC10) suffered the same failure of an improperly secured cargo door in 1974 (two years after American 96). As you mentioned, mcdonnell douglas did not modify the poor door design, so it was only bound to happen again, this time at the expense of all 346 on board.
EDIT: Just realised you already did a video on this incident as well, good stuff :)
great series ! better than anything on the TV
Just some free youtube engagement; don't stop making these!
Seconded!
Mentour: These retrospective explanations of tragedies and near tragedies in the air, particularly those whose pilots and crew responded resourcefully to damage rarely, if ever, encountered. You have a special way of presenting the facts and causes in a very organized and informative manner. Thanks for doing these.
Floor collapsing while losing pressure. That is a good nightmare.
Wow what a story. Thanks to the professionalism of the pilots and crew, everyone survived. Phew... 😰 I love that teaser ending. I’m looking forward for next weeks episode!
Just curious but have you never heard of this one before?
I know what next week will be. It was avoidable. I hope you didn’t see my previous response if you aren’t familiar with that similar accident.
Next week’s episode isn’t going to be like this. I know what it’s going to be and the teaser at the end sent a real chill down my spine.
And this was the only accident involving the DC-10 cargo door that ever.....oh.
But it was the least deadly I suppose.
the FAA really loves having blood in its hands...
@@makecba Why blame the FAA when the primary fault was McDonnell Douglas? (And the politicians who crippled the FAA's resources - sound familiar?) That's a bit like blaming the police for the crimes of the Mafia.
@@cr10001 because the NTSB issued its recommendations and the FAA just published a service bulletin... Wait for next week's episode and you'll see how it ends up.
@@makecba Yes, we know. There's an entire chapter of the 1976 book 'Destination Disaster' (which is mostly about the DC10) dedicated to the FAA's failings. But these were exacerbated by political interference from above, budget cuts, and intensive lobbying from McDonnell Douglas who didn't want any aspersions cast on the reliability of the DC10, least of all an Airworthiness Directive. (Sound familiar?)
Rockstar. The knowledge your passing on is so important, I find myself consumed and hanging on every new detail.
I have no understanding or knowledge of piloting but your clarity and precise descriptions make these videos absolutely fascinating. Thank you sir. You are obviously brilliant in your field
Keep these videos coming please!!!
Its so impressive how well the flight crew handled this problem. Very good to shed light on how pilots can save everyone on board in a situation like this is very uplifting to hear about even if it happened quite some time ago. You usually only hear about the tragedies, not how often pilots evade disaster with great professionalism and a lot of training. 💙❤️
Indeed! That did a fantastic job here
United 232 was similar symptoms (different cause, the tail engine exploded), only considerably worse. The crew there did an equally amazing job, if not more so, but were only partially successful.
@@cr10001 I was thinking of that incident while watching. I hope he gets to that one at some point.
It would be interesting if you do a video on United flight 811, which shares some significant characteristics with this incident (though, sadly, it included the loss of 9 lives); it’s also an interesting story in that the NTSB investigation was reopened, and a new report issued, after the cargo door was recovered from the ocean floor. On a much less serious note about AA96, only 56 passengers aboard a wide-body jet? The pre-deregulation days of air travel in the USA...
There are still some flights that go with light load as the ac has to be in place where the next day's passenger and cargo load makes big money.
That must have been terrifying for the passengers. Of course, this is when the professionalism of the pilots and not of course forgetting the cabin crew comes into play. To be honest Captain, how the hell your colleagues time and time again bring their crippled aircraft back down to a safe landing whereby everyone leaves the plane alive, let alone uninjured simply blows my mind. I love these investigations, they give if you like, a birds eye view of what went wrong, in a way that no other investigation channel on RUclips can do.

Gotta love Mentour... this series of air incident investigation videos are concise and right on point, yet so interesting, without the (in my point of view) over-dramatisation of Air Crash Investigation and similar programmes.
11:00 Wow! Amazing animation!
Finally, a Mentour video without any loss of life content warning!
I saw this incident before on another channel so it was a delight to have you move in with more explicit information to fill in where there may be questions or uncertainty to what caused this and what was done. Thank you. ... And I love the retro pictures. I am old enough to remember that time and it is a travel back. It feels almost like I am there so it becomes an experience for me rather than an explanation. Experiential teaching is the best and most motivating kind of teaching, even if it is in a classroom or through a video.
Love the analysis as always - well done again! Keep 'em coming! I appreciate hearing about less well known incidents like this one in addition to the major incidents. Thanks!!
Hi Petter. My wife doesn't understand how I can watch your videos so much... Because I simply love them 😍
Thank you! Glad you are liking them!
I love these accident analysis videos so much! Thanks for all your hard work in making them!
I've just discovered your channel and, even though I'm no pilot, your explanations seem very thorough, intelligent and interesting. No extra melodrama and no bias. Just detailed scientific and engineering facts. It's amazing how many sophisticated things an aircraft has and what they can cause if not properly cared for, yet how safe it is to travel with them. I'm also amazed how calm you pilots manage to be in catastrophic situations, which is the key that saved countless lives. Keep up the good work :)
I'm always impressed how you're able to add insight and details to incidents and accidents I already know and thought I fully understood.
Great stuff!
I'd love to hear your take on Korean Air Lines Flight 007. I know a big part of that story has to do with cold war politics, but there's lots of other interesting things there to do with navigation, tracking and GPS
Commercial aircraft didn’t have GPS back then
@@tomstravels520 I know. But this incident is one of the main reasons why they did end up getting it.
@@papaquonis oh I see. I thought you were trying to say it had GPS and it malfunctioned or something
If they didn't have GPS it must have been very close to happening. I retired from GA in August 1984, and some months before that the avionics repair station I worked for was trying to get approval for installation of a GPS in a light twin. The circular that came out for it (I don't recall if it was an AC, and I don't see an AC for GPS in 1983 or 1984) said to call a number in Washington if we were having trouble getting approval. I called and our GADO inspector was out two days later to get it going. He asked, "Why did you call Washington?"
Or Iran Air Flight 655.
You may already be ahead of me but a good video for next week would be the following TK981 accident where you can mention what still caused the crash to happen despite the “fixes” and how MDD promised the FAA they’d fix the issue if they didn’t issue an AD. Also didn’t this aircraft during testing have the cargo door fail in a pressure test?
Coming up
I know nothing about planes, I flew twice in my life, so I can tell you explain VERY WELL. Thank you for your work
Once again a famous and very sad accident that you have explained better than any other documentary that I have seen about this crash.
Keep up the good work, you and your team deserve an Oscar.
Take care, Jeff
Your production and editing quality has become amazing. I'm really enjoying these videos. Keep it up, Petter!😀
With hindsight one might say there is something broken with the relationship between the NTSB and the FAA why the reluctance to issue an AD?
Could it be our old friend money.
Loving these, Mentour. Keep up the amazing effort and work you're putting in to these! Always in-depth analysis, well-structured yet straight to the point based on factual information. Superb.
How on earth are you able to make these unbelievably fantastic videos!?!? You're some kind of genius that also happens to be an incredible communicator. Just perfection. I'm constantly in awe and completely addicted. You could explain literally anything to me and I would listen absolutely riveted indefinitely. Brilliant...
They were lucky that they haven't climbed any higher when the door gave way.
The damage such a small hole could cause is really terrifying.
That's why I would never want to mess with pressure vessels..
I can do a lot of stuff myself, but anything pressurised or gaseous, I won't touch. I'll hire someone to do it properly. I have too much fear/respect for pressurised stuff. It's basically a bomb waiting to go
Hey - maybe only 8-9 psi across the floor. What could go wrong?
I really enjoy these videos, this was similar to United Airlines Flight 811,where Kevin Campbell who lost his son actually proved the door mechanism had a serious fault and Boeing clearly knew this but continued using it.
AF477 Atlantic crash would be super interesting! Thanks
