Just my observation of all these flight dramas is...pilots should first learn to fly gliders (not rely on engines ) that way they will actually FLY .Then introduce engines.They seem to lose all perspective when they have no engine power !

[@tarassu]

15,494.5 hours of flying time is irrelevant information. Please keep it up to 2-3 "significant figures" for flying times. And pretty much most data (maximum 3 significant figures is acceptable as all extra is memory clutter inside our brains) like weight, fuel on board etc (you can also add "about" to specify rounding). Therefore 15.500 hrs of flying time and 7700 hrs of flying time. DO NOT be more precise. Thank you :)

"has to be excused" - The end never justifies the means and does not and should not absolve the flight crew of remediation to train and fix their errors. Had the flight crew understood bleed load hogging and closed the pressure valves to slowly bring engine number 4 back up to speed at a proper altitude, then they would have increased their chances to gracefully recovered from the pending disaster without risking all the passengers' lives. The only commendation here goes to the engineering of the aircraft for holding together through over 5g accelerations. Future passengers now get to unknowingly endure the horrific possibility of repeating these events with the same as-yet-untrained flight crew as they continue to fly with no remediation and therefore no belief they themselves could have done anything differently.

I’m an ATP and an FAA gold seal flight instructor certificate. Also hold every fixed wing certificate out there over the past 35 years. I’m medically retired now but need an aviation fix often and these videos really go along way toward keeping me in touch with the knowledge I can no longer use but still enjoy thinking about. I, like so many others, believe pilots should go through aerobatic training and when an airline pilot should have extensive training in simulation recovering from severe unusual attitudes. I had some great sim instructors who loved to place me in unusual attitudes to recover from. One instructor would place us in a night IMC scenario with a mix of malfunctioning instruments or engine loss. Once successful and time permitting, we be given nothing but our emergency instruments. One thing I noticed, while instructing, a lot of pilots panic more when they loose automation than when they loose an engine. Hand flying in a high mental load environment often results in an incomplete sim session or an outright failure. I realize these scenarios are extremely rare in real life but they do occur therefore we need to train for them.

Honestly, this is one of the stories less well suited to build trust in the aviation system, as the pilot(s) mishandled it quite a bit. Cant say i blame them, but still. He has a few stories like that, which is a bit disheartening. Like the one with the pilot that felt superior due to his experience and started lecturing and looking down on his second pilot, which ended in a huge tragedy. Or the one with the airport that had horrible safety standards and a lot of broken stuff, where you just end up asking yourself how that's even possible. But those are the exceptions, not the norm. There is also a planeload of videos that really make you look up and respect those pilots for their decisionmaking and how they handle stress. Like the Hudson Miracle, or his currently newest video about a beoing nearly crashing into a mountain, which i really enjoyed. Or the one where a passender had to land a plane, where you really felt all the experts coming together to help. Amazing stories.. even more so because they are real.

[@WorldTravelerCooking]

One of the fundamental problems though is that we, as humans, only understand facts when they are situated in narratives. If you don't understand how the instruments are showing something so heavily messed up, it will be very, very hard to understand them. Confirmation and continuation bias both come from this. I totally understand how this works. I am not in aviation but I have worked on large, complex IT systems and I have been bit by similar cognitive biases. What I am wondering is how the captain (pilot flying here I think) failed to notice the roll until the upset was so heavily developed. I would have expected an instrument scan to notice the roll before that point.

I was on a ATA (American Trans Air no longer in business) L1011 coming home to Indy from Vegas back in the 90's that made a 1000 foot drop in a split second. We actually went over a patch of turbulence so strong and the captain later told us over the intercom that there was a downdraft that robbed all of the lift from the wings. When we finally stopped dropping and the lift caught back up, the amount of G force we felt was incredible. Just before it happened the attendants were going up the aisle with the little drink cart and they suspended drink service. If they had not, that cart would have been airborne for sure. I know if I didn't have my seatbelt on I would have smashed the overhead. We were flying over the Rocky Mountains in the late summer/early fall. To fall 30,000 feet in 2.5 minutes would have been so much worse. We diverted to Omaha immediately and spent 6 hours there while they checked over the plane. 7 hours later we were airborne again.

If you mean the artificial horizon, attitude indicators can definitely fail, and the most likely reason is from a loss of power scenario. Which they thought they were experiencing. They can also fail as a result of rapid changes in speed or direction, which they definitely did experience.

[@B_-.-]

They can fail, but there's several and they'd fail independently. The chances of all 3 failing at the same time is extremely low. What's more, is there are vertical speed indicators and altimeters that would've shown that the plane was actually diving also. In essence, there should always be enough info to know if you're flying level in terms of altitude. Bank not so much, but it's still extremely unlikely you'd lose all instruments indicating bank angle.

Why a gimballed ship's compass isn't fitted to all airline dashboards I'll never understand! Seems too much emphasis on automation and too little on remaining "situationally aware" (knowing up from down for instance!).

[@seventh-hydra]

@@B_-.- Keep in mind reliability, and awareness of systems from pilots, was a lot lower in 1985. I can understand where these pilots were coming from. And they took the right procedures to attempt to correct the false "issue." Aside from attempting to re-light the engine too soon. I feel like people are coming down way too hard on these pilots. Especially compared to the reaction I saw for Air France 447, a modern crew on a modern plane, yet somehow everyone acts with sympathy towards the "confusion" of the pilot who was doing nose hard-up in a stalling aircraft. 🤦 After being told to go nose down by his co-pilot _and_ captain.

[@B_-.-]

@@seventh-hydra I didn't say a word about the pilots. I just explained that a failure of every instrument indicating that the plane is climbing/descending is extremely unlikely, even in 1985. "Pilot error" is an overused phrase that pushes blame onto pilots when in actuality, the people who are responsible for them - airlines - should be held responsible. There are some causes where a pilot does something totally stupid, but 90% of the time, you can root the issue back to lackluster training, lackluster experience, or a trail of small issues that no one put together previously.

[@hposnansky4222]

At Hamilton Standard we designed and built the engine fuel control, as well as the stator vane control scheduler for that P&W engine. One of the tasks of the fuel control is to limit both the acceleration of the engine to prevent the turbine temperature to exceed a certain limit and the deceleration is also limited to prevent flame out.These functions override the power lever function as does the altitude compensation. In those days the TIT (turbine inlet temperature) could not reliably be measured. This temperature was computed by measuring the much lower compressor exit temperature and then a temperature increment was computed by the fuel controller based on the compressor pressure , to determine density, rpm to to determine airflow , and the fuel flow limit was computed based on the allowable increment to reach the TIT allowable. At high altitudes the density is low, nearly a fourth at 42000 feet, making the temperature very sensitive to fuel flow. Bleeding compressor air on that engine will reduce the compressor exit pressure significantly and limit the fuel flow more than on the other engines, resulting on exactly what was observed: a noticeably slower engine acceleration, to protect the turbine from overheating In other words: the engine (and fuel controller) were working as designed at that altitude.

[@NicolaW72]

The NTSB really missed an opportunity to recommend measures to mitigate fatigue and monotony in the cockpit, because it was brought up in the report. Even jet lag was mentioned, as the captain went through so many time zones in the past week. Jeddah to Taipei, then a couple of round trips from Taipei to Japan, and then Taipei to LA all in the last week. The NTSB could've recommended limits on how much load a pilot takes on on a weekly basis, or how to make the autopilot more pilot-friendly, and not merely mask problems, or how to make sleeping in planes more achievable for the pilots.

The Air crash investigation episode on this is my favourite of all time.

This incident fascinates me so much, because it's the union of two things that rarely happens. Firstly, the pilots make big mistakes in dealing with their situation. Secondly, those mistakes resulted in the plane falling from the sky. Those two things would usually result in an in-flight breakup, or just a crash that would kill everyone on board, and the pilots would be seen as incompetent. However, that didn't happen. What happened instead was that the plane somehow stayed together, the plane was very high at the start, so they had more time to fall and figure out what to do, and they saved the airplane and managed to land it safely despite problems with the elevators (well, the problem with having almost no elevators left on the plane lol). It's the union of the pilots screwing up so bad AND the pilots getting themselves out of a situation that you would forgive a pilot if they couldn't recover from it. Usually it's one, the other, or neither, but almost never both. It's the union of the best and worst of what a pilot can do. Something not mentioned in the report nor the video was that the captain crossed so many timezones in the past few days, which may have affected his judgement via jet lag. He also didn't get good sleep during his rest period (rested for 5 hours and slept for 2 hours) to the point where he was in the cockpit at times during the rest period, which may have also caused problems with performance.

[@jtjames79]

Design flaw also. That first procedure with the bleeder switch should have required a checklist. These things only require checklist because Boeing doesn't know how computers work. So that's a design flaw, sort of an ongoing one. SpaceX can land a rocket booster on a boat with nothing but GPS coordinates and a few consumer computers.

[@jtjames79]

@ The 5160 came out in 1983, and Boeing is still not up to that level. The only reason there isn't autonomous fixed wing auto pilot is because nobody has paid for it. For multirotor I can solve the problem with the computer the size of a quarter. Not because it's easier but because the early adopter tax was paid a long time ago. Yes it requires a certain level of hacking skills, but that's almost entirely because there are no standards forthcoming from the FAA to automate against. Something that should have started in the early '80s. So like 40 years of "not invented here". Literally no one from Boeing ever thought to ask John Carmack to help.

AS engineer here, these days we try to build thing a bit more closer to the edge, meaning it won't be over designed like it used to. But for structural components they are designed to take 2.5 G sustained (something almost never really happen in-flight in turbulences), on top of that safety factor is usually 1.5. that means the plane can take at least 3.75 G load. This must be destructively tested on wings already went though cycle testing, mean a pair of wing will be loaded and unloaded many times, like bending a paper clip. After it passed the cycle testing, it will be loaded to that 3.75 load. If it didn't fail, more load will be put on there untill it breaks. The test is usually done with everyone present (quite impressive to see), including FAA because the 2.5G requirement is written in airworthiness detective, no test, no certificate.

In fairness, it's not always black and white like that.

[@reyjusuf]

I remember the Mayday/Air Crash Investigation episode of this flight. One passenger interviewed said "we landed safely, thats all that mattered. They got us into it, but they got us out of it."

[@Gadget0343]

I remember this one. What I remember from it, the plane went supersonic in the dive and the shock waves are what ripped the tail apart. The wing was bent but still within limits. I thought the pilot lowered the gear as a speed brake, but that does not seem to be the case. The plane was sold to a church group and flew on for many years. It was recently put up for sale or was repoed or something.

Global Peace Initiative, linked to the Brahmananda Saraswati Foundation. Religious? Yes. Church group? Not quite. Swami Brahmananda Saraswati (aka Guru Dev) was the Shankaryacharya of the Jyotir Math monastery in Uttrakhand, a state nobody has heard of, that is located right between Uttar Pradesh and Tibet. Guru Dev's most famous disciple in the west was TM founder Maharishi Mahesh Yogi.

[@TimothyChapman]

FAA: "All commercial aircraft must withstand at least +2.5g vertical load." Boeing: "We'll build our aircraft to withstand 50% more than that." Pilots: Exceeded *THAT* by over 30%. I remember another video I saw on this accident. It's incredible that the plane wasn't ripped apart by the *combined* overspeed and over-g loads. I'm pretty sure that the safety margin that is from VMO to VD (design speed) was not designed to be used in this manner.

[@laredobenjamin7438]

I'm not sure, but maybe it's because the certification is based on the maximum stress the structure could encounter in flight, which means that it probably includes a fully loady and fully fueled plane. Had this incident happened just a the beginning of the cruising phase with a fully filled center tank, the structure may not have been able to whithstand the forces, and the plane would have broken.

[@Dmoneyaka]

Actually at one point it was a 100% of 2.5G

[@dmytrogubskyi4355]

"We'll build our aircraft to withstand 50% more than that" - it's not Boeing's decision. It's a regulatory safety factor of 1.5, imposed by the authorities as well. And even that, as I recall, is not an ultimate structure limit, but the limit at which the plastic deformation starts (as it did in this case too), so… yep. Still - this is an example of impressively strong structure.

[@AaronShenghao]

Even the Boeing Engineers were amazed seeing the plane after it landed. Lucky it was a SP and 747 was initially designed as a military transport. The plane is a write off.

[@fritz46]

Over 50 years ago while certifying in the altitude chamber, I learned to ALWAYS trust your instruments. Thank goodness this aircraft wasn't flying at night!

[@hotlavatube]

Talking about the limits of the airplane, I'm reminded of American Airlines Flight 587 where the first officer used such aggressive rudder control, the vertical stabilizer tore completely off. Apparently AA was partly to blame due to how they, at the time, taught to use the rudder for wake turbulence recovery.

[@NickanM]

My dad is a pilot and he gets mad when he sees failures like this in the cockpit, because a lot would’ve changed if the pilot had declared emergency and used the rudder.

[@LaBamba690]

This to me just seems inexcusable. First, these pilots had plenty of experience and training to know what to do in the case of asymmetric thrust but failed to do the basics. Second, every airline pilot knows for a fact that the 3 HSIs are completely independent. So to ignore them, when they all agree, is beyond stupid, it's pure, unadulterated incompetence. Third, the altimeters are also independent and would have been violently spinning when the plane was in a dive. I'll tell you, if I was informed that any one of these bozos were going to be a pilot on a flight I had made reservations for, I would immediately cancel it.

[@deathstrike]

To be honest, while I do agree with you that the cockpit resource management was exceptionally poor and that there were completely avoidable mistakes, there is one thing that affects pilots. And that is complacency, where high hour pilots and crews seem to ignore or outright deny what is unfolding in front of them. No matter how experienced a pilot you are, there is NO excuse for ignoring checklists, trying to draw one from memory, or not using them. They are there for a reason. It's unfortunate what happened to this aircraft, and if anything we as pilots should all reflect when we fly "Are we following procedure?" "Are we flying in a manner that shows our professionalism and dedication to our craft?" These questions MUST be addressed by all who call flying their profession. Anything less, and we might as well be the death of hundreds of passengers, or ourselves.

[@materliliorum]

Well, at some point, they managed to bring the aircraft back into horizontal position and to land it... So I'd say they've shown intermittent good skill...

Totally correct. Taipei Taiwan is not in China. It's the Republic of China (Taiwan) and not the PRC. The video has the Taiwan flag rendered on the tail of the plane the whole time.

I've pulled 5Gs in the back seat of a T-38C. It was pretty intense in an aircraft rated to take it with a g suit. I can't even imagine doing that in a passenger liner. Props to Boeing's old school engineers!

[@IrisRiedel6]

The fact that this aircraft was still intact (minus the stabilizers) and the passengers lived to go to the hospital or board another plane is astounding to me. I'm both freaking out and laughing hard at this whole situation. Amazing flying by the crew and amazing craftmanship of the plane. Also can't imagine the G forces.

[@mikebel74]

These incident analyses are brilliant. It’s like seeing an analysis of cardiac stent insertion by an actual cardiovascular surgeon versus a bunch of actors, dramatic music, and added drama. I mean, the incident itself was dramatic enough. Thank you for these videos. They’re highly instructive, and may prevent another such event from happening in the future.

[@filanfyretracker]

It should also be noted that the G's taken during spaceflight, especially now with everything being capsules is always Eyeballs In. A position in which you can take mid to high G loading with far less issue. Given this was G force to Feet direction on the 747 incident I bet a few passengers momentary blacked out at 5 G.

[@Mr.Scootini]

Imagine the cabin crew and the passengers at the very tail end of the plane must have felt. 😳😳

[@UKairways]

@@Mr.Scootini The tail moves about more but I always felt the nose gets the extra Gs as its doing the pitching up whereas the tail needs to go down relative.

[@konstantinkh]

@@UKairways G-forces come from acceleration, not movement, so constant rotation only adds centrifugal effects which will be about equal front and back. And if you have considerable rotational acceleration to add on top of the 5Gs due to the wing loading, the frame will definitely give out. So it's likely that the G-forces were fairly evenly distributed, and good thing that. The place where rotation does make a lot of difference is aerodynamic forces, and a sharp pitching maneuver at high speed can create additional aerodynamic stress on the tail section on top of the high loading due to vertical velocity caused by rotation effectively increasing angle of attack. Which is probably why the wings managed to hold and the horizontal stabilizer didn't. I would also speculate, purely based on the fact that permanent deformation suggests how close they came to the failure point, that maybe losing parts of the elevator helped prevent pitching up even sharper and losing the wings.

[@KnightsWithoutATable]

Yep. 4 G to 6 G is the blackout point without a G-suit on. It can be even less if you are less healthy and on your body shape. Tall people tend to have problems earlier, but there are a lot of other factors.

[@konstantinkh]

@@liam3284 That's all true, but all of these forces are going to be the same across the aircraft. You can decompose the motion into center of mass movement along the arch, which generates most of these 5+ Gs and rotation around center of mass, which is not going to contribute significantly compared to that at any sort of rotation an aircraft is going to survive at these speeds.

Same when sitting into car. In January one coworker had left home to buy groceries and ended up waking in hospital with wrist and couple ribs broken and no idea of what happened in between... Pretty sure without seatbelt he would have been as totalled as the car whose wheel Mr. Newton had taken on icy road for meeting with tree. In another case like dozen or so years ago some driver did enough speeding that when car hit traffic island etc structure, engine and gearbox literally tore through car's front.... While only significant injury was broken wrist/arm.
