This is one of the most infuriating flight accidents I've seen. It's hard to find excuses for those three in the cockpit. Their stupidity and complete incompetence cost them and all those people their lives.

[@JoeB2490]

Worth mentioning is, that the crew was on very short alert. The original plane and crew could not execute the flight due to some problem with the plane. They where on very short notice (just two hours) but more importantly, they where already waiting for weeks on the island, as the company didnt want them to fly the plane back empty. Safe to say, they where desperate to leave. The report states that human factors and the split second decision of the captain to continue take off was influenced by these factors. Not an excuse though.

[@christopherpetit1718]

Basically a single insect ended up taking down a Boeing 757, because a veteran captain didn't cross check the other air speed indicators, or even listen to the relief pilot who was trying to fix the problem.

[@longdonglarry]

@@JoeB2490 to continue the take-off was not the problem. I'm stunned by the incompetence that they were unable to compare all those speed indicators and make a conclusion. Especially the captain. Man, that guy should not even have driven a bus.

[@JoeB2490]

@@longdonglarry It certainly was. You are drawing the wrong conclusons. We call it flying "ahead" of the plane. Thats why we check at 80 knts if eerything is going to plan. Once airborn with a smallish failure like this this escaltes quickly as the work load is already high. Yes, it is a minor failure one would think its easy to deal with. But in reality, in the sitaution it self it can get out of hand fast. Dont forget: The human mind works way way way worse in stressfull conditions. Thats why its absolutely critical to fly ahead of the plane. Because it keeps stress levels low and therfore decrease chances for human error.

[@longdonglarry]

@@JoeB2490 I agree. Rotating with that malfunction was certainly the second mistake(the first mistake was to not question the working conditions of the tubes after sitting unprotected for weeks), but still somewhat forgivable. At least not fatal. But how the hell can you not compare the 3 speedometers with each other once airborne? And the cherry on the cake: You get the stall warning and still ignore it. It seemed like the 3rd pilot knew what was going on but had no balls to advise the cap. in a clear manner. You see that often when plane accidents happen in certain cultures. The cap. is god and as a FO. you'd be crazy to question his decisions no matter how false they are. It sounds like you are a pilot and I understand that you guys don't call out other pilots even for the worst mistakes, but I'm wondering what you're really thinking in such a case. The AF crash is another one of those.

I think it's not while crossing the ocean on Autopilot for hours and hours that a pilot is learning to handle problem situations. I think the total flying time is almost irrelevant (or even maybe a disadvantage) when encountering a stress situation. A pilot with that much experience runs on 'autopilot' himself so much that an unexpected issue can become 'impossible' or 'unlikely' in his experience that he doesn't know how to handle it. Every accident video (and I've seen a few) starts with how many flight hours the cockpit crew has accumulated. I think a more important figure would be the total sim time and the results of the pilots performance during that would be more relevant, don't you think?

[@c-puff]

I was once doing a back to back flight from LA to South Africa via France with Air France. Because of my country, I needed a transit visa to be on the French airport. This means I am allowed on the airport but I am not allowed to leave it. While at France, about to fly home to South Africa, the pilot announced they were having trouble with one of their indicators and there would be a delay. About 15 minutes later, the pilot came on again, sounding annoyed, saying they were still having trouble with the indicator, and they plan to reset it a 2nd time, and if it did not reset the way it was supposed to, the flight would be aborted. This was a little terrifying to me, because I had no idea what I was supposed to do as a solo traveler with extremely strict stipulations regarding my visa. Obviously now I know there are hotels on the airport itself where you can spend the night. But at the time there was no way for me to connect my phone to wifi to contact my family back home and let them know I would be delayed by a day. (this was the late 2000s). Luckily, the pilot came back on saying the system reboot fixed all issues and we would be able to continue our flight. The rest of the flight was completely uneventful. The full delay was between 30 - 40 minutes. It was scary for me as an individual at the age of 22 traveling by myself as to what I was supposed to do if something was delayed this way, but it was also a useful lesson, because before this point, I had no idea that something like a malfunctioning DISPLAY was enough to abort an entire flight. And it taught me how overly cautious flying is. (which as a nervous flyer was a relief) Perhaps in retrospect the flight should have been aborted at the first malfunction ^^; but it all worked out ok in the end.

Insects in the pitot tube are a fact. I'm a pilot, a few years ago two friends and I flew a Cessna around Australia. We stopped for a few days on the far north coast and when we took off we discovered we had no airspeed indication. After we landed we discovered a wasp had built a nest in the pitot tube. Exciting addition to the trip!

[@tomstravels520]

[@josephdantes1605]

Captain was probably out of his element. There were a bunch of warnings thrown at him. He probably wasn't able to tie them all to his own airspeed indicator, or realize his faulty air speed indicator was causing all of this. So if his mind is thinking about how to deal with these warnings individually, he definitely lost sight of the bigger picture. Seniority probably finished them off. Lots of airlines/cultures respect seniority where you don't question the most experienced guy.

[@mycroftsanchez901]

Souns like a culrtual thing going on there where younger pilots are unwilling to challenge the senior pilot, it's happened in Korean and other aitlines. One of the pilots was aware of the issue as he kept shouting ADI but the captain ignored it. A sad and preventable accident.

[@juliemanarin4127]

You're right! If I were the junior pilot my mouth would be working overspeed! Sorry but it is my life too...among all the innocent crew and passengers in the cabin!

[@stevesteves945]

It's called crew resource management (CRM), and it can absolutely be a cultural phenomenon. If the cockpit power gradient is too steep, the first officer may be reluctant to challenge the captain if they observe them making mistakes or raise questions if they feel concerned about something. It's interesting that you specifically mentioned a Korean flight that crashed as a result of CRM. In most cultures it's taught that authority should always be obeyed and never challenged, but in Korea it's particularly stringent. I'd suggest looking into the sinking of the MV Sewol for a perfect, yet heart-breaking example of this. In 2014, a ferry with almost 500 people onboard, primarily Korean high school students, began capsizing off the coast of Korea. The ferry sank over a time period of hours, giving the kids ample opportunity to escape, but the captain ordered them to remain in their cabins. The captain then abandoned ship, and the kids remained where they were as instructed as the ferry was gradually sinking. There is even cell phone footage taken by the students that show the inside of the ferry listing heavily, almost sideways. You can see the students almost standing on the walls of the ferry, yet the students remained put. 300 people died.

Pitot tubes should have a system that blows high-pressure air out of the tube before flight to ensure that there isn't a clog. That would also blow off any tube covers that a crew might have forgotten, or blow a hole in the tape that brought down another flight.

[@SamPinchesMakerShop]

Or even just pressurise the tube enough to confirm no obstruction

[@davidt8087]

Or rather than redesign it, just put pitot tube covers, you know, like how it's done everywhere today from small planes to jets. Of course then there's that one flight where the pilots forgot to remove the pitot tube cover. And the fact the airspeed on thr captains side increased is what you learn as a PRIVATE PILOT with like 20 hours. If your pitot tube is blocked and static port is working, then your airspeed works like an altimeter, if you go up speed goes up

The day was cold bright and sunny and the walk around did not show any ice on the plane. We had vfr conditions and were able to return to the airport safely.

[@procrastination2204]

Seriously. I've never flown any aircraft before so I don't know what it's really like in there, but just from watching a few dozen Green Dot videos, every development in this story was completely predictable and I knew exactly how to solve each part. And when he said that they were decreasing their speed, I was already saying "so are they at least going to listen to the stall warning?" and of course when it came, they did not. Obviously it's a lot harder to think clearly when you're in that emergency situation and with all the contradictory alarms blaring and everything, so it's easy for me to criticize from behind a screen without having lived the experience. But for fucks sake if you can't handle something as simple as 1/5 speed indicators being incorrect, a problem that you knew from the moment you powered on the engines, then what the hell are you doing being a pilot?

[@juliepeasley7131]

It appears that aside from passing a rigorous testing process for a captain position, they really don't have to show that they can and will handle difficult situations proficiently. In other words. A captain may have 10k plus hours in an aircraft but it could mean very little if he was lucky his entire career. You are basically a passenger for those 10k hours if nothing ever goes wrong. Its not like a fighter pilot that may face difficult situations every flight. Some of these guys have a great record with thousands of troubl e free flights. But the moment they have to make their money and take charge, they crash. Ive seen lots of supervisors in different professions that once they are put to the test, they can't produce. Maybe simulations should be more comprehensive and challenging. I don't have an answer but not knowing your speed should not result in this, ever.

Okay, I'm not the most avid aviator in the world, but I DO love my experimentals... (ultralights for those who aren't sure)... AND I have to point something out (and a question involved)... I've worked on and with a LOT of engines. Under a given load, I've NEVER seen an engine that didn't have a consistent output. That means, wherever you set the throttle for a specific speed one day, it's going to be the same (or VERY close to it) on any other day or time under the same load... In the experimentals, at least, most seasoned pilots could tell you if you've got an issue, just by the throttle setting and air-speed indicated... Say, 80% throttle, and you're doing 60 knots, they KNOW you've got trouble. If it's "running rough" they can even diagnose that, practically on the spot. "Oh... backfires and misses... You're either out of gas, or the fuel lines are clogged." Things like that... SO the question... Is it really THAT big a trick to LOOK down at the throttles for whatever the autopilot's doing and then match to the air-speed indicated and say, "Yeah, that makes sense." OR "Nope, this one's busted, too. That CAN'T be right." Look, I'm not about bashing the people involved. I think the FAA and NTSB (among others, et al) have done enough analyzing... I'm interested in a clever detail to think about while you or anyone is aspiring to be a pilot or to improve yourself AS a pilot. Maybe take some time and occasionally STUDY those throttle positions as they associate to the actual speed of the airplane. Then if something weird, like this, happens, you have an easy, quick, personal check you can do that will lend acknowledgement to what the issue actually is, almost instantly... If you're throttles slip back under the autopilot to 30% and the speedo' keeps insisting that you're going 280 to 300 knots (or something ridiculous) you can grimace and say, "Welp, this one's FUBAR, Cap'. You got a good airspeed over there?" AND get into the QRH, and start on those procedures and check-lists, rather than scratching heads and butts and wondering if the aliens have finally hacked into your plane's brains and took over... ;o)

[@IIIlIIIIlIIIII]

You're right. In fact, in the handbook each pilot has, there is a chart tabulating engine throttle, pitch angle, and resulting air speed. It is possible to fly with no airspeed indicators using this chart (and this has been done in emergencies before).

[@gnarthdarkanen7464]

@@IIIlIIIIlIIIII Thanks, I thought as much... which makes what these guys did even a tad more confusing. ANYWAYS, it's worth at least a foot-note somewhere so the relatively inexperienced can "catch up quick" and maybe learn so they don't repeat those kinds of mistakes. Even without the chart, a casual "visual assessment" should make some sense of things. You know? Then one pilot can start "doing the hard math" (referring to charts) and the other can get back to focusing on flying the plane. ;o)

I know that, 26 years later, things are better, but the main thing is responding appropriately under extreme real-world pressure.

Good video. I thought I was familiar with this incident but in fact you've drawn my attention to the fact that only the Captain's ASI was defective. This makes it particularly perplexing. Presumably, his experience stopped the other 2 pilots being more assertive. Truly a gross CRM failure, the plane was perfectly flyable.

We have a small mud wasp in Australia which builds its nest in any small gaps or holes during the warmer months of the year. It catches small spiders, paralyses them and entombs them along with wasp eggs in a chamber constructed within the mud - the spiders then becoming food for the newly hatched wasps. I have on numerous occasions gone to start a brushcutter or mower only to have it refuse to start. Experience has taught me to check things like exhaust outlets or air filter boxes. It's surprising, but true, that these insects can pack enough mud into the exhaust outlet of a small petrol engine to prevent it starting. And just because you checked yesterday doesn't mean that it isn't clogged today. They are very fast and tireless workers. I imagine that such an insect could render a pitot tube utterly useless in about half an hour.

[@rcairflr]

@15:37, he describes the Pitot probes as sticking out and measureing airspeed. It is not that simple. Airspeed is actually a difference in pressure between the pitot probe and the static port. The static port is simply the pressure at the given altitude and what is used to indicate altitude. The Air Data computer also has a correction called SSEC (Static source error correction), it is a calibration that takes into account the angle of the pitot probe and the angles of the fuselage that affect airflow into it. So the reason the blocked pitot port gives a reading at all, is because when the bug blocked th pitot tube, the ground level pressure got locked into the pitot probe (approximately 14.7 PSI). As the aircraft ascends, the static pressure goes lower and lower. So now the difference in static and pitot pressure gets higher, giving airspeed indication. But also at the same time, the SSEC correction is also doing its thing and also affecting the airspeed reading. As the announcer said, this should have been a very basic troubeshooting by comparing all 3 indications and throwing out the one that was different.

[@davidt8087]

Blocked pitot tube+working static port= airspeed increases during climb and decreases in descent. Literally 20 hour student pilots know this. But I'm beginning to suspect aviation knowledge isn't paramount or important in other countries like parts of Europe, most if not all of Asia, middle east, Africa, and the central and south America's. Why? Poorer countries, people can't afford flight training, so the airline gets involved hiring people and training them for free. In those countries you Can fly a jet on the right seat in as little as 250 hours. What motive will the airline have when training their pilot and what regulations will countries have where the people are poor and can't afford flight training? First, the airline will probably be subsizdied by the government, and regulations and safety stuff will be very relaxed. And the airline only cares to fill the right seat quickly, so they focus mostly on everything it takes to get from A To B in standard Conditions and maybe a few hours of emergency conditions, which very quickly those pilots forget. Plus they're taught to over rely on autopilot. Combined this sets up a recipe for disaster when even the mildest malfunction occurs. Even a private pilot in the US, would not crash this plane and would quickly realize what's happening with the airspeed indicator. Like ffs

Love your content I keep watching your videos over and over. Thank you and have a great day 😀😀

[@RobertHollander]

Quoting the video, "If the airspeed gets too low, the airplane will fall out of the sky." I'm trying to put a positive spin (pun intended) on this and I can't think of anything to say except that's not true. To state it in simple terms (even though the phenomenon is not aerodynamically simple) an airspeed that is too low will cause the aircraft wings to stall. If no action is taken to recover from the stall, eventually the aircraft will crash. However, stall recovery is a crucial part of pilot training, even for beginner pilots. Proper procedures for stall recovery are practiced repeatedly. Rarely do stalls result in accidents and never do they simply cause an aircraft to "fall out of the sky."

[@OccidentalonPurpose]

I'm not even a jet pilot and this is one of the most frustrating one of these videos I've seen.

[@mahqindia2414]

That captain was very lucky to survive 24000 hrs of flying. Sometimes experience makes people rigid and resistance to change

[@davidt8087]

24,000 hours where he used autopilot 99% of the time and nothing ever went wrong or nothing serious. The one second something went wrong that he couldn't handle quickly by pushing a button or following a checklist he's inckmpotence was clearly demonstrated and he crashed. In the US private pilots know exactly what it means when the airspeed reads 0 then suddenly seems to work when climbing. It indicates a blocked pitot tube. And a non imbecile pilot would realize the first officers speed indicator was working right from the start and at rotation speed they were able to take off normally, meaning the speed was correct on the FO side. Rather than use that side, the standby airspeed, etc, the captain and whole flight crew just showed they were not compotent. They were simply direct airline hires. In poor countries where the masses can't afford flight training airlines hire people for free, and train them directly from zero to first officer in jet at 250 hrs. To save costs, they only teach the absolute minimums to go from A to B plus a few emergency scenarios which are quickly forgotten because failures happen rarely. In the US, aviation knowledge is paramount and so is safety and you can't fly for an airline until 1500hrs and the airline hires you once you have 1500hrs, they don't pick you up from the street and train you from zero to 250hrs to fill their right seats. This kind of pilot making is disastrous. Correct me if I'm wrong but if you're in south America or Africa or asia tell me how do you even become a pilot outside of being luckily chosen by the airline academy and trained freely? General aviation doesn't even exist in Asia or Africa. Who can afford it anyway?

[@efficiencygaming3494]

The part where the captain compared his faulty instruments with those of the first officer and declared that "both of them are wrong" infuriated me. How did he come to that conclusion when he didn't even bother to check all the other indicators in the cockpit? A gut reaction? It's not like he could have known that from prior experience... The captain was probably aware of all the flying experience he'd amassed and fancied himself the finest aviator in the world, when in reality he was only extremely lucky up to that point and was grossly unprepared for an emergency...

Given the critical importance of Pitot tubes, why are they not built to blow out a puff of air as part of the start-up routine, to ensure that the tubes are clear (e.g. to blow off a missed tube cover)? Why not also have a backup tube in the body of the aircraft, that could be automatically deployed when the regular tubes malfunction, or do not agree? I also don't understand why the aircraft would not automatically ignore the reading from a tube that shows a reading different from the other two tubes and substitute the reading from the backup tube - that's why you have a backup in the first place.

[@SeekingTheLoveThatGodMeans7648]

If a pitot tube clogs on the ground, shouldn't this be immediately seen during the takeoff roll once significant motion is underway and be part of a takeoff configuration alarm? This would seem to me a last chance to catch the situation before the craft leaves the ground.

[@holyfordus]

It wouldn’t set off the takeoff configuration horn because faulty instruments have nothing to do with the state of the flaps, slats, etc. Those had all been set correctly on the flight, anyhow. The problem was something that would only be caught by the two pilots cross-checking their respective instruments during the takeoff roll, which they did. They *should* have aborted the takeoff then and there, but they wanted to get going. Patience pays.

[@davidt8087]

⁠that doesn't explain the crash. It's just sheer inckmpotence plus in poorer countries people Dont get hired as pilots, they beckme pilots by being trained from zero to first officer for free by the airline directly. The only motive the airline has is to fill the right seat as quickly and cheaply as possible. They don't care much about teaching pilots aircraft, aviation, weather, and so much more other knowledge, and etc. Just the basic minimum regulations, knowledge, and piloting "skills" to from a to B in standard Conditions, with maybe a few hours of emergency procedures which the pilots forget. It's completely different in the US where safety and aviation knowledge is highly emphasized and paramount, and first officers become first officers after 1500hrs of self dedication to get that many hours. Not in other especially poorer countries. Airlines just pick names and then start them off to go as quickly as possible from zero to airline pilot .

[@philmorris8862]

One of the most important aspects of a good pilot is a clear head and the ability to think quickly and rationally under pressure, and of course experience and training. However at night when the computer or other systems malfunction, as systems are want to do, it is the ability of the pilot to remain calm and think logically that makes the difference. Here for what ever reason, the Captain could not do that. This could be for any number of reasons such as a head cold, allergies, loss of cognitive ability from age or other causes, alcohol or other drugs, or just not having that ability to begin with. We will never know what precipitated the Captain's confusion and slow witted actions, but this is a perfect example of how deadly poor decision making can be in a modern aircraft. Also at some point one of the other pilots should have just taken over and made themselves heard. But do not forget the first mistake which was not to abort the takeoff when the speed indicator was not working and the failure to follow other check lists. The series of blunders that eventually led to a situation that required clear thinking was seriously negligent. 🌵🌵🌵

[@corneliakobilke4638]

Ive flown out of this airport many times…thanks for telling this!

[@kevinmalone3210]

It's always a chain of events that lead up to these accidents. A faulty airspeed indicator, on the Captain's instrument panel. He could've easily aborted takeoff and went back to the terminal to have it repaired. Then the Capt makes a big assumption that the airspeed is wrong, by just going by his own airspeed instrument when there were 4 other indicators to tell him what the correct speed was. The crew didn't bother to question to Captain's erroneous conclusion, and just went along with his call, incredible! Poor cockpit resource management skills to say the least! The autopilot put the plane in a pitch up attitude, causing the plane to stall, and the crew didn't notice this, until the plane started stalling, when all they had to do was disconnect the autopilot, and take appropriate measures to counter the stall, nose down, increase power, gain airspeed and gradually pull the nose up.

Apparently they ran a series of simulator tests using the Birgenair accident as a model, with experienced pilots in the seat. Every single pilot, when faced with simultaneous overspeed and stall warnings, froze up. I can't help but wonder if the captain's age played a role, too. 61 is very old for a pilot in civil aviation, especially as I doubt Birgenair strictly enforced rest periods or had good refresher training. I've seen photographs of the guy, and he was not in good shape either.

A few observations. I've actually experienced the tunnel vision that causes pilots to ignore the obvious instruments which are working causing them to lose situational awareness. Not related to flying, but when I get the idea that something is missing and panic, I begin to feel the fear that it's gone then I can't actually see it right in front of me. Like an email with contact info. On to the pilots. 1) The captain actually did something early on which since it was left uncorrected is what led the plane to crashing. He turned on the autopilot when the airspeed indicator it relied on wasn't functioning and he knew it wasn't functioning. I know that pilots don't always know exactly how the autopilot works. Did the pilot know this and just forget or did he not know it? If he knew that I would think he wouldn't have turned it on in the first place. 2) While all 3 pilots temporarily lost situational awareness, not realizing the plane was headed for a stall, both the FO and the relief captain did seem to figure it out and kept trying to get the captain to pull it out of the stall, but the captain never seemed to understand and therefore follow their hints which then morphed into panicked commands which either were ignored or came too late. Notwithstanding the captains confusing orders NOT to pull up.

One important point to add is that this crew wasn't expecting to fly that night, they were called up replacing another flight and they had remained in the Dominican for a long period before that.

In engineering, we have the notion of a regression test suit that must be passed before every release of a product. Over time, this test suit accumulates all the experiences from real failures encountered in the field with the objective of never allowing a past failure mode to repeat itself in production.
