Douglas' So-Called ‘Solution’ DOOMED Them! United Airlines 608 & 624

[@khosrowzare8301]

Good to know the Douglas safety culture managed to survive all the way to 737Max.

[@redwaller1]

This is exactly what I was thinking about.

[@pjohan74]

That was exactly what we all were thinking about.

[@321ssteeeeeve]

Or the C17

[@fareedmasood]

Agreed 100% ❤👍

[@tourmaline07]

I was thinking that Douglas not documenting crucial design changes to their pilots and trying to hide things from the regulators seemed all too familiar - even in a company they ended up buying half a decade later ;) Also to a group of concerned pilots "everything's entirely satisfactory - us shoving as much CO2 at aircraft fires as we can manage , but there's a few little vent holes which you need to open first against your intuition before you know you're on fire so you don't get incapacitated.... ['putting in a system which could trim the aircraft nose down very quickly without indication , and which would keep doing so every five seconds even if you tried to counteract those trims unless you did something counter-intuitive to turn the autotrim off] is all good and dandy , now shut up [stop telling us we need to specify simulator training for this magical new system and killing our potential sales and $$$] ....

[@alzo7891]

“Do not share with CAA.” That Douglas culture that now runs Boeing has roots.

[@MentourPilot]

That’s what I thought.. when it first read it

[@Isnt_that_Aaronic]

The defence knew this was an admission so tried to hide it. I hope they got disbarred

[@vidura]

You also have to be quite psychopatic to do what they did with the warning.

[@khosrowzare8301]

The fact that the chief pilot wrote it is even worse. If it were a random suit, it would be less disturbing. Everyone knows they are part lizard anyway, but the chief pilot should really know better.

[@gr8xr7]

[@ThatWouldBeCareless]

I'm so used to aviation as you describe it today, with layers of safety nets. It's so weird to hear something so safety critical relying on unpublished procedures done from memory. It's amazing how far the industry has come in a relatively short time.

[@aaaaaaaard9586]

I see that everyday on the road, granted not the same industry

[@jursamaj]

Well, it was "unpublished" because it was never meant to **be** a procedure. Douglas never intended pilots to cross-fill the tanks.

[@MeppyMan]

I was flying in GA in the 80s and 90s and saw plenty of that sort of thing going on. Attitudes have come a long way since then thankfully.

[@MGower4465]

​@@MeppyManTell me about it. I took *a* flying lesson in the late 80s, my parents bought a block of time as a graduation present. Mind, I had lived airplanes firever, studied the physics. Instructor decided it was a great idea to wrap up the first lesson by flying along the river *very* low, not quite dipping the tires. This in a Cessna 152, not an aeribatics aircraft. I got home, told my oarents ti get their money back - I refused to fly with that instructor again. I didn't know how to fly, but I did know that was not safe. A year or so later I heard he lawn-darted and crashed, possibly as a result of trying an inside loop too low. Again, in a utility/trainer plane. He d8d3n't take anybody with him.

[@UnknownUser-j3n]

You can add safety nets to the planes, not to human greed and corruption. I am sure they are as much in force today as they were back in the 1940s.

[@XpOzgamingx]

The Douglas company becomes McDonnell Douglas, which becomes part of the modern Boeing company. A history of covering up design flaws that has been written in blood.

[@rauljosechaves3291]

I thought the same thing. I'm curious, but I don't remember reading about old Boeing or Airbus trying to cover and deceive regulators like Boeing did after DC merge and DC did in the past

[@Isnt_that_Aaronic]

Now. You have to think about Douglass greatest casualty. Lower than expected returns on shares. The humanity/s

[@NathanSimonGottemer]

@@Isnt_that_AaronicTHY981 did cost the company a lot of money. Sadly those that suffered those consequences were the employees and not the execs that made the choices that got 400 people killed

[@giftofthewild6665]

[@philippal8666]

I have deep respect for those who trained problems directly on the plane, with no simulators.

[@RoyalFusilier]

You've got a point. "Hey, we think this aircraft has a potentially fatal design flaw, you down for a quick jaunt?"

[@ibrahimkayikci2146]

​@@RoyalFusilier test piloting and test driving are not the safest occupations, similar to stunt piloting. There are things hard to test with simulators. Asphyxiation risk is one of them.

[@essiebessie661]

The old timer pilots (like Dad) often said the simulators didn’t train pilots to handle emergencies realistically. You just can’t react the same as when you think a mistake will kill you.

[@mangos2888]

I suppose they also think no practice is better than simulated practice, too. ​@@essiebessie661

Agreed! Was about to say this myself.

[@bennewman566]

15:30 It's the Civil Aeronautics Administration in the 40s, not the Civil Aviation Authority (which is the UK's aviation regulator). To be fair, there have been a lot of names for it, so it's easy to get muddled. I've listed them below for anyone interested: 1926 - Aviation Branch (of the Dept. of Commerce) 1934 - Bureau of Air Commerce 1938 - Civil Aeronautics Authority 1940 - Civil Aeronautics Administration & Civil Aeronautics Board 1958 - Federal Aviation Agency 1967 - Federal Aviation Administration edit: sorry for being a bit nit-picky, but the history of aviation regulators is a topic I am very interested in so I couldn't help it.

[@jedisith25]

Being a lifelong enthusiast of planes and the history of aviation, I find these "window into the past" episodes utterly captivating and believe they would make a fantastic series. While I’m not a professional in the field and lack formal qualifications or commercial experience, I hold a profound admiration for the pilots, crew, and all those who contribute to aviation. It's remarkable how these episodes thoughtfully address past accidents, highlighting the progress and advancements in the industry over the years. They provide a refreshing and distinct viewpoint. Please continue producing them-I’m eager to see more!

[@jamesengland7461]

THIS!

[@ChaJ67]

I was once a passenger on one of the last DC-6's flying people inside of the continental United States. Way back I was in the Boy Scouts and we took off from the Coronado naval base in a DC-6 to fly out to San Clemente Island, a military controlled island. I remember very well the four piston engines thrumming away and flying a lot lower than a jet airliner, bouncing up and down in the more turbulent air at that lower altitude while over the Pacific Ocean. It wasn't a long flight from Coronado to San Clemente Island, but of course it did take a lot longer in a DC-6 than a modern jet airliner. I heard they finally decommissioned that DC-6 some time after I went to the island with the scouts. But this was in the early 1990's when I flew on that DC-6.

[@fridgeffs5662]

I'm an engineer. At 14:00 as soon as I saw the air inlet I was like dont tell me they're unintentionally pissing fuel out of the plane. Oh my god. Who made that system and didn't put a valve in?

[@CalcG]

yeah this whole airplane is so asinine to me. but i guess it was the 1940s and we didnt have the experience to make fixes like that and take safety as seriously as we do now.

[@Juan-qv5nc]

I'm a regular person and thought the same until just before "Oh my god". Instead I cursed.

[@giftofthewild6665]

I started watching your videos because I really has a severe case of aviophobia. I still has the phobia but I gained something different from your videos: my English is getting better! I'm learning English as 3rd language and my listening isn't very good yet especially with heavily accented British English. But whenever I watch your video I can understand every words you said without turning on the subtitles. Your pronunciation is just so clear that I can understand everything even when the explanation becomes too technical. Thank you for helping me learn English and I hope I can overcome my aviophobia too. Thank you for your good work!

Your english sounds good! For non-native speakers it's easier to understand other non-native speakers. This channel is perfect in that regard as Petter speaks in a structured and clear manner. Moreover, in contrast to e.g. TV series, Petter speaks at the same volume. In TV shows, the loudness may vary making it even harder to understand. It may happen though, that you get a quite "technical" vocabulary. I was often told that I don't speak like a native as I use academic vocabulary for every day stuff (I just don't know better).

[@wilfreddv]

To be fair it causes way less panic that way, I guess...

[@vasilivh]

@@wilfreddv carbon dioxide causes severe agitation and hyperactivity before unconsciousness and death, so a cabin (and cockpit) filled with CO2 is paradoxically way more panicked

@ Oof - wouldn't fancy that then. Its remarkable how much power these massive companies have, that they can bypass all sorts of safety regulations to maximise profit. Still, par for the course I guess its just...a worry.

[@NicolaW72]

[@aimeedean1]

I really wish you'd find it in your schedule to do a video on the Comet and how the crash investigators gave the first real roadmap for how they solved these accidents. I think it's interesting to find out just how they went about investigating and what practices and lessons learnt way back in the 1950s are still used today with investigating air accidents. Pretty Please Petter!

[@MentourPilot]

I’ll see what I can do

[@NicolaW72]

Indeed.

[@trinity72gp]

The evolution of Air crash investigation 👌🏾

[@Simple_But_Expensive]

So McD was covering up design flaws for profit. Years later Boeng buys them out, but keeps the management team. Suddenly, Boeng starts having accidents caused by design flaws attributed to things like quality control inspections being cut to save money and design flaws not being communicated to pilots or the FAA. Correlation? I get the feeling Starliner and 737 max are the tip of the iceberg.

[@Juanguar]

Do keep in mind that this is before Douglas merged with mcdonall So you could say that culture is embedded in Douglas

[@mz00956]

well let's be honest. McD bought Boeing and got Boeing to pay for it

[@aaaaaaaard9586]

What do you expect, companies to prioritize safety over profit? The aviation industry became safe thanks to external audit and political pressure not the high moral standard of manufacturers. This is sadly not the case in the automobile industry where everyone blames the victims and drivers, not the oversize 3 ton death machines designed to maximize profit.

[@Simple_But_Expensive]

@@Juanguar Fair enough. It seems to be a strange form of genetic contamination.

[@uzlonewolf]

@@aaaaaaaard9586 While profit is one of the reasons, the biggest reason the road is filled with 3-ton death machines is emissions regulations. Those huge machines are classified as trucks which allows them much more emissions, whereas something smaller like a station wagon is classified as a car and basically cannot meet those emissions requirements.

[@EricRush]

My father avoided flying in new models of aircraft. He wanted to give them a couple of years to get the bugs worked out. He cited the DC6 fires as examples.

[@_Dimon_]

Not a bad idea. There's also a 737 max as a more recent example.

It is now, but that was pre NTSB, in the old CAB days, and 9 years before the crash over the Grand Canyon with the (first?) very meticulous investigator, and the realization that air traffic could no longer be a freewheeling, cowboy style, adventure, leading to changing the general aviation paradigm completely.

[@joefin5900]

My first cross country flight was in March of 1958 on a United DC-6 from Stapleton to Idlewild. Great flight, great food and, great when the plane ascended and descended due to the atmosphere at the cruising altitude. On landing, great blue flames issued from the exhaust port just outside the window! Thrilling for a kid.

[@tomriley5790]

I had no idea that Douglas history of shady practices and evasion went back so far, I'd often looked at the DC10 accidents and wondered what was going on with the culture there and then obviously later post merger with Boeing and everything leading up to MCAS but this is crazy, just shows how entrenched company culture can become.... Good to know the story about why pilots have full face oxygen masks too. Also can't help wondering why didn't the pilots land in a field in the first fire?

The DC10 saga was marked by inadequate 'fixes' even after the fault was known and a 'gentleman's agreement' with the FAA to minimise costs and risks - to McDonnell Douglas.

The transition from the background of the DC6 into the day of the accident flight was a masterclass in storytelling. Brilliant as always from this channel.

[@gzk6nk]

That wasn't the end of fatal accidents caused by the DC4 / 6 fuel system. In 1967 a Canadair Argonaut (basically a DC4 with RR Merlin engines) of British Midland Airways crashed in Stockport on the approach to Manchester Airport with much loss of life. It had lost power in engines 3 & 4 through fuel starvation caused by inadvertent cross-feeding of fuel which could happen if certain fuel control levers were not FULLY pushed into position. There had been earlier non-fatal accidents and incidents to DC4s through this cause and it was thought the danger was well known among DC4 crews who would ensure the fuel levers were fully pushed home. However, that knowledge seems to have evaded the crew of this Argonaut. The crash of the aircraft, Hotel Golf, would make an excellent Mentour video! There have been suggestions that the wrong engine was shut down (one of them was never feathered), and of very poor CRM (it was a long time ago!) and also possible crew fatigue leading to poor decision making (the first engine failure happened on short final to Manchester, but instead of simply landing on the runway just a couple of miles in front of him, the captain decided to go around to try to trouble-shoot the problem).

[@hollandsemum1]

Good point. The concept of serious, detailed research into cause and effect wasn't anywhere near what it is today, so probably little forethought as to how a fuel system designed for shrapnel wouldn't necessarily transfer to a different use context.

And that was the video that finally tipped me over into subscribing and doing the Patreon thing. Excellent work and research by all involved.

[@amandaseneviratne3605]

Yay! Another video from Mentour Pilot!

[@mitchyk]

Good to know things haven't changed with companies trying to avoid responsibility. Hence me never taking any company at it's word! I love these looking back videos. To see how far we've progressed.

[@bobbydigital_BobbyinLA]

Beautiful video Petter and Team!! Your videos are pure class!

[@MentourPilot]

Glad you enjoyed it!

[@kruksog]

Love what you (and your team) do Petter. Thanks for making quality stuff.

5% CO2 is crazy. I have witnessed partial incapacitation at levels or 2% in indoor conditions in IT environmments.

[@flygirl6048]

The 1930s and 40s were the Wild West of aviation. I'm so glad for all the safety standards and procedures that we have today... Even though those standards and procedures were written in blood.

[@blatherskite9601]

Superb analysis, Petter & team. Very well done!

[@richardstaples8621]

My first flight as an 11yo boy was on a TAA DC6 flying from Sydney to Canberra on a school excursion in 1963. Great excitement. No fires.

[@memes4themasses365]

Back to back weekend uploads! , how lucky we are

[@domkelly1972]

Whats amazing about the first story is that the pilott at 42 was born in a world that basically no passenger airplanes existed. Can you imagine him explaining his job to his parents or grandparents?.

[@timothystamm3200]

They probably thought of him as similar to the conductor or engineer of the equivalent of an airborne train or a driver of the equivalent of an airborne bus.

[@bucc5062]

The 624 story was an eerily similar story to what happened to the 737 Max accidents. Airline company skirts requirements, limits or does not inform pilots, squawks when called out, does little as possible and more people die. Hmm....who started running Boeing after the Merger, right, McDonald Douglass. Great video and I also appreciate looking back at older moments in aviation that helped make it safer in the future. A suggestion for a video would be the Eastern Airlines DC-10 that flew into the everglades because of a faulty light. I read the book years ago and still found it hard to understand why.

[@alexandermonro6768]

Eastern Airlines flight 401. Basically, all 3 pilots got distracted trying to find out why the "Nose gear locked down" light didn't come on, and nobody noticed that the auto pilot had accidentally disengaged.

[@jessstone7486]

@@alexandermonro6768 They failed to aviate - navigate - communicate! I've learned things from this channel 😃

[@alexandermonro6768]

@@jessstone7486 Well, they certainly failed to aviate! Navigation wasn't much of an issue, and they were communicating with the approach controller.

[@NicolaW72]

Indeed, exactly my thoughts, too.

[@bucc5062]

@@jessstone7486 I agree. The three tenants that was pounded into me as I learned to be a pilot we're aviate navigate and communicate. What's more interesting is potentially the lessons learned from CRM because the part I didn't understand was three pilots that distracted and it'll be an interesting review.

[@Car_guy31]

Douglas, or McDonnel Douglas, even after purchasing Boeing in 1997 with Boeing's own money, is doing the exact same thing with their planes. Greed never dies apparently.

[@PC_YouTube_Channel]

An American plane manufacturer disregarding safety recommendations, lying to authorities, and covering up known deficiencies?! Wow, I'm glad we've come so far in terms of regulating these companies and putting people before profit!

[@billeldon]

That will shortly be just fine, as our new “hands off industry!” regime starts dismantling all our safety advances of the past half century.

[@NicolaW72]

Yes.

[@MikeJamesMedia]

Wow... As a young man, (age 10 and 11) I flew on both the DC-6 and DC-7. Thankfully, they were normal flights, and for me, a huge amount of fun.

[@Pixx2266]

I LOVE these old airplanes and "old-timey" content like this! Thank you Petter! :)

[@MarinCipollina]

Thanks for this one, Peter !.. I think there's a wealth of history you could explore involving older incidents. I hope such stories aren't being bypassed on the basis of being too remote.

[@koini11]

Enjoyed this one. An interesting tale from the past. I appreciate the work since the details must have been harder to bring together

[@brianbrino4310]

I flew the DC6 many times and in one of my flights the far away engine caught on fire fortunately 5 minutes away from our landing Airport! The air stewardesses offered us some drinks to distract us from the problem but I did see the engine burning and started to pray in silence! It happened in engine # 4!

[@brbhave2p00p4]

The systems we had back in the day were crazy. No to minimal regulations, up with the disco ball pretty much

[@jonaskuula5218]

its wonderfull to see into the early roots of civil aviation, really gives a morbid reminder, why modern procedure and rules are so thorugh.

[@madvova118]

Mentour Pilot! Thank you for the video. Can you please do a detailed review of how new planes are tested before they are released for commercial use? For example, when they built a new plane, who does the first flight? How do they know it will work? How about the systems that they put in place, and new bank angle limits etc., it would be interesting to know.

[@CompletelyRandomlyBroken]

What a gorgeous aircraft! I've been waiting for you to do an episode on this plane. Pleasantly surprised it's not about the shape of the windows. I have also been hoping for more episodes on older models of planes. Flying used to be glamorous and luxurious. What a time to have flown.

[@catpillowws]

consistency of quality uploads is insane! :D

[@disorganizedorg]

Overall quality is top notch, but I got a giggle at the animation glitches at 3:28 with people seeming to straddle the sides of the air stairs.

[@psychomd1939]

Back in the day, Bob Hope took a USO group to Europe one year and and to Asia the next to entertain the troops at Christmas. There was another USO tour that went to the opposite continent. It featured Johnny Grant. He was the biggest thing on the air in Los Angeles . . . known as the mayor of Hollywood. In 1959, I was on that Asia-bound flight with Johnny, the dancers, singers, musicians, a couple of celebrities, et al. While there was jet service across the Atlantic at that time, there was not yet jet service across the Pacific. It was two-hour stops in Honolulu and Midway and 34 hours and 15 minutes in the air from San Francisco to Tokyo on a chartered Quantas DC-7. We didn't get to see the Gooney Birds flying - they were nesting. The return trip, a year later, stopped on Wake Island and Honolulu and was a couple of hours shorter. It was on a Navy Super G Constellation. The seats faced to the rear, except I presume, in the cockpit.

*Minor point: In this context, piston engines quit due to fuel starvation; they don't 'flame out'.* *Edit ---> More like this one!*
