On July 31st, 1992, a Thai Airways Airbus A310 carrying 113 passengers and crew mysteriously vanished over the Himalayan mountains in Nepal. There had been no distress signal from the pilots.
Days later, the wreckage was discovered miles from anywhere the plane should have been flying. How had the crew of this flight ended up so far off course? When investigators analysed the flight data recorder and cockpit voice recorder, they were baffled.
For years, flight 311 would serve as a case study for airline pilots worldwide, and as a cautionary tale for anyone flying into mountainous areas. This is the story of Thai Airways flight 311.

This incident shows us the importance of situational awareness and sharing of workload between the pilots. Even if the first officer wasn't allowed to become a captain, it doesn't means that he is not allowed to fly the plane. This accident had multiple factors like no Radar, no cardinal directions or self-dominance which could have been prevented.

[@ripwednesdayadams]

I have noticed a pattern in a lot of aviation disasters. Specifically in situations where pilots make a mistake without realizing it. When the plane alerts them to the problem, the pilots often think that there is a problem with the plane instead of realizing that they made an error. Are electronic or mechanical problems common in planes or are the pilots over confident in their abilities?

[@georgittesingbiel219]

After watching a number of these videos, I'm convinced that the pilot is usually unschooled in operating a plane's computer system. The younger FO often will have a better understanding, but the older pilot will disregard the FO. Just my opinion.

[@dylanbennett958]

@@georgittesingbiel219 I’ve noticed that too man. I’ve heard several of his stories where the younger less experienced pilot is completely disregarded because of an ignorant and arrogant pilot and moments later everyone is dead. Not even enough time for the co pilot to at least get in a “I told your dumbass” I don’t quite think a lot of people truly understand just how quickly things can go bad and when they do time might seem to carry on but it’s truly extremely fast. You’ll hear a lot of passengers say “it felt like we’re falling forever’ but for the pilots they feel they don’t have enough. I heard a fighter pilot say once when they do there extremely low flying maneuvers they have something that tells them how quick it’ll take for them to hit the ground from the height and speed they’re traveling at and sometimes it’s only 2-3 seconds. SECONDS!!!! Think about that. So basically one small mistake at that moment is going to be catastrophic

[@gernhard.reinholdsen]

Overconfidence is my guess

[@MisterPlanePilot]

As a pilot, I can tell you that is human nature, to nearly automatically disbelieve what an outside stimulus is telling you and instead believe and look for anything to affirm your current mental model. It is called confirmation bias. Humility is an extremely hard thing to have as a human, and the best pilots have it. There are a lot of incidents just like this one where the pilot doesn't believe what the information is telling him, but what you haven't heard is the many more where the pilot realizes he did something wrong, believed what his aircraft was telling him, and quickly fixed it.

if you're spatially disoriented, from your perspective you've just been teleported to a random position and orientation and should proceed as such. maybe they should implement that as a feature in flight simulator training, sometimes you fly into some clouds and suddenly you're facing the wrong way and 10km north. maybe add it to the lore of pilot stories as a new type of gremlin that teleports your plane when you least expect it. then you don't have to risk questioning your superior's innate sense of reality itself and getting into an argument about who's right, you can just point out that the gremlins did that thing that they sometimes do where they teleported the plane, we gotta re-figure out where we are.

This is a good description. I once suffered spacial disorientation while piloting a boat in extremely thick fog and turned to an incorrect heading, which was going to bring me crashing up onto an island - and this was WHILE my full-color GPS chartplotting display (boat version of avionics) was right in front of me. It never happened to me before and never since, but I count it as one of the scariest moments of my life. Fortunately within a few minutes I was back on course. I imagine adding the variable of altitude makes this much worse all around. This can also happen to novice boaters at night, but you actually tend to pick that up and get used to it fairly quickly.

Yeah. That was stupid - The blame is with faa for allowing idiots to be pilots. Old school pilots who didn't rely so heavily on computers , and those trained by them directly are much better pilots - they tend to find a way to land a plane in all kinds of bad shape. They use common sense and experience and often figure a way to get unlandable planes on the ground safely. Because their minds are sharp and they know how the planes equipment all works. Whereas , folks who rely on computers, rely on computers to know how the plane works and wholy on the computer for navigation - can barely land a perfectly good plane in adverse weather , much less can they solve problems, improvise , and land a crippled plane.

[@alexburke1899]

@@aaronwalker8847 Old school pilots had more accidents and died more often though. I don’t think technology has made air travel less safe. It’s still almost always human error and rarely a computer error. I agree modern planes are more complicated and it would be hard for a old Spitfire pilot to figure out but I still think they are much safer. There’s always going to be untrained pilots and airlines that don’t provide enough training. With bad weather and mountains it’s kind of impossible to fly without being instrument rated and with modern gps.

It's absurd that, at any time since WWII ended (but most certainly by 1992), that any airport in the world which serves commercial flights is without basic radar services. In my view, that's as big a cause of this accident as anything else: the lack of a generally standard monitoring tool that helps prevent inevitable human errors from becoming catastrophic. Sounds like the report mentioned it as an afterthought. Why do the inevitable situational mistakes by the worker-bees always outweigh the ill-advised deliberate decisions by the bureaucrats? smh

[@rainscratch]

Fully agree. And one of the world's most perilously located airports amidst some of the world's highest mountains, often subjected to fog and heavy precipitation/cloud cover. An insanely absurd oversight. If aircraft are under strict airworthiness, maintenance and regulatory requirements, pilots are under constant health and psych monitoring and re-training, how can any airport be allowed to operate with the most basic safety requirements of such items as Radar?

[@alexl.4170]

The radar at the airport would only have a range as far as the mountains surrounding the airport on each side. In mountainous terrain, ground based radar would be useless. They would have to build a massive mast towering over the peaks surrounding the airport and put the radar on top of that for it to be of any use.

There was a reverse CRM problem that likely contributed to the AA587 disaster in Nov of 2001.

I have watched so many of these 'air desaster' stories and two things strike me as odd and should be addressed for safety. 1/. There seem to be several airports without radar, particularly in hazardous terain areas. How is this allowed? 2/. Pilots flying in poor conditions suddenly get a terain warning, they instantly give full power and pull up but still crash. Why does the terain warning not go off in time to save the aircraft in so many cases? Anyway thank you for posting these videos, they are well put together and very informative.

[@jeysonbraun4250]

1. Each country is responsible for installing and maintaining radar equipment. Some countries have less resources and radar is not always a priority. Of course, more and more are gaining radar coverage nowadays considering many of these accidents happened 30 plus years ago. 2. GPWS (Ground Proximity warning... or terrain), is done by onboard radar looking forward. It can't always work well with enough time for outclimbing the obstacle if the aircraft is going very fast and /or the terrain ahead is too steep, as in a sheer cliff ahead. Especially back then, 30 plus years ago, without GPS and computing power we have now, If it was programmed for more of this sudden climbing terrain, the GPWS would give many false alarms on more normal descents and approaches, making it a problem as well.

[@huskkyy]

@@jeysonbraun4250 Hi, just for clarification, GPWS does not have its own radar system. It’s GPS based and works off of a pre documented terrain map

[@jeysonbraun5205]

Hi, I don’t think you are correct… GPWS works off the Radio Altimeter using it’s radio waves to map off obstacles within a certain altitude/distance. First iterations came out in the 1970’s well before GPS. Today GPS nav programs do warn of obstacles and altitude conflicts but that is not the same as GPWS.

[@huskkyy]

@@jeysonbraun5205 Hey, I am an A350 FO and I’m not familiar with systems on other aircraft however in the airbus, I don’t believe it’s tied into the radio altimeter, electing to use aircraft position and velocity to determine whether the aircraft is at risk of a collision. You’re right about the GPS statement though, I misspoke there and you’re right that GPWS was working before GPS was used in aviation. They do however did have IRSs and did have an accurate picture of aircraft position and velocity, even before GPS. However, in the 737-800, A3XX family, and even the Q400, it’s entirely computational and position based and does not use the Radio Altimeter or Radar. GPWS and EGPWS in the airbus is disabled with the IRSs in ATT mode, meaning it does not keep track of position rather just how the aircraft is moving. Again, I could be wrong in other cases however for my aircraft specifically it’s not tied into the RA.

I love your videos and I literally have nothing to do with aviation. Been watching non stop for 2 weeks now

Excellent content

Thank you very much!👍

I went to kalkani in Nepal few weeks ago where the memorial for the deaths from the crash and I saw alot of names of those people who sadly passed away

Radar installed at an airport. It's an interesting concept. I guess knowing where things are as important? Fascinating.

[@roncoburn7771]

your videos are great

[@FalcoGer]

Never assume things. And certainly never assume GPWS alarms are false unless you can clearly make out the terrain visually, and even that isn't always simple with snowed in mountains looking like clouds. Also I don't understand how any airport where airliners are landing, don't have radar, much less so airports where there is an elevated risk, such as mountains all around.

[@bogdiworksV2]

cost cutting, most likely. Related, have you ever watched videos of those dangerous roads in like Pakistan or the Andes? In countries with less stringent safety rules, drivers/pilots put up with conditions that to us look crazy.

[@Matthew...1979]

I just Adore your channel. You keep me entertained at work when there's down-time, and I regularly continue watching when i get home from my loooong shift. I have Microsoft Flight Simulator on my Xbox Series X and tend to recreate your stories on my own. What an amazing channel. I'm extremely grateful to have stumbled across it. Thank you sooooo much!

[@nightchieftain]

Thanks for making the vid! Watching the vid fresh at the end of my night shift. Greetings from traumatology dept!

[@Onoelo23gf]

Do note that the pilot was required to do very little. Apart from autopilot handling, the captain took over R/T commn. Keeping track of the compass is ingrained into a pilot. That's buggerall of a cockpit load at relatively low speeds. Only a poor pilot will turn 360* in place of 180*. Think of a fighter pilot who flies solo, handling everything from start-up to switch-off. The aircraft is at high speed and altitude variation is very large, to be completed in a short time. He is brought up this way and finds switching over to an airliner easy to handle. He requires snap-snap R/T commn. He might find it confusing for a few months till he understands all civil terms used, that too at a leisurely pace, but that is what a simulator is designed to do.

[@ginamiller6015]

I’ve got to think adoption of GPS is going a long way to mitigate this kind of situational awareness difficulties. Navigation has got to be a much easier task now.

[@tabuti23]

Poor crm,poor airmanship by captain.. 😕

[@MrSturdystratus]

Well done. New subscriber here

[@majorvonhapenallthetime8602]

No radar is simply pathetic. It's akin to relying upon a couple ROC observers, trusting to luck on their aircraft recognition and phoning in their sighting to the control tower.

[@augusthoglund6053]

You'd think it would take one day of thick fog for people to realize this

[@user-jd3kb4of2b]

Great video! Can you also do an episode on another accident at Kathmandu, the US Bangla 211 from 2018?

[@pmc2999]

Sad that the hubris of the Captain made him unwilling to listen when he was warned a mistake had been made.

[@rexhall1130]

A trend in many of these accidents is no radar.

[@SteveMangezvo]

Im no aviation expert but im starting to think that its almost criminal for an airport not to have radar

[@raven_1133]

Quality as always.

[@awfominaya]

I just keep getting a sense from these videos that if the way point isn't where you expect it to be, gain altitude then figure it out up at altitude. Is this taught? Why so many cases where pilots seem to think the flight management computer must be wrong. Misplaced waypoint = I did something wrong. Right?

[@nocomments5029]

Some people can’t admit mistakes. Mistake gives them too much shame. So they gaslight and project the mistake onto someone or something else. Cluster b

[@Jjjkluejnek]

It took 4 attempts to reach controller during a landing in monsoon. That’s just pathetic.

[@lyedavide]

There will always be people who, justifiably or not, think so highly of themselves that they become arrogant and belligerent towards those working with and under them. In this case, if were the first officer, I would have relieved the captain of his control of the aircraft, and dealt with the consequences later. Better to lose my job than my life. One man's ego killed everyone on that flight. That is the real tragedy.

[@CAROLUSPRIMA]

Excellent as usual. My hearing isn’t what it used to be and a bit more volume would have made this perfect. Thanks.

[@jacksak]

Maybe wear headphones? I have bad hearing but wear phones which make a big difference.

[@CAROLUSPRIMA]

@@jacksak Yeah I wear headphones on my smartphone but watch on TV. It’s a little bit of trouble to synchronize these but worth it. Thanks.

Thanks for the feedback, I'll increase the sound levels in future vids.

I often use subtitles on videos, and Green Dot speaks very clearly so these work well on this one. Another option.

@Steve Robinson I'm not sure what's 'funny' about a tragic loss of life. You must have a very twisted sense of humour.

[@-theislander-5888]

does NO ONE have/look at a single compass in these fking planes?????? it boggles the mind.

[@harmeetsingh9446]

Arrogant pilot who thought the first officer was incompetent was himself woefully incompetent and shouldn't have been allowed pilot license in the first place.

I was watching the video and realising that I’m watching it on the day of their crash anniversary 30 years ago 🙏🏻❤️😭💔

[@SeekingTheLoveThatGodMeans7648]

I wonder why not a bird's eye view of the plane and its past path on a display chart that has a preset compass point (typically north) at the top. That would show very quickly that the craft was in the wrong place and/or pointed the wrong way -- and if so, also how it got there. This would have to be modified for flight near a pole, of course.

Sounds like we need to stop building airports near mountains. Idk. Just a thought.

[@cantfindmykeys]

My friend flew into a small village in the Himalayas for a few days on a small plane over terrifying mountainous terrain. Night before he flew out he went to the only bar for a drink. These 2 guys were shooting pool and drinking and he played a game with them. He wanted to get some rest for his early morning departure and they wanted to continue drinking and playing pool. But he said No thanks and went back to his hotel room. Early next morning he boards the little plane and hears his name coming from the cockpit. The 2 guys from the bar the night before were flying the plane. True story.

[@neilfoster814]

This seems to be a problem with many Asian airlines. the Captain is God, and must be treated as such, anyone else is clearly inferior to their status and must NEVER question the Captain. As clearly shown, this leads to poor CRM with one person often overloaded with tasks, leading to mistakes going unchecked. This HAS to change, or accidents like this will continue to occur.

[@xItzSpruce]

Theres ppl from my home country in from Finland. Anyways idk why but these videos are insteresting idk why. Best one in my opinion was the one that when the plane managed to glide without any passengers dying

Ridiculous and absolutely hate it that very minor things on Airbuses are always pointed out as "issues" and the relatively higher level of automation is spoken in a negative tone whereas even real and serious issues on Boeings are brushed off as "another contributing factor" or "the stepping stone for better safety" and therefore in a positive light.

[@SMaamri78]

And on top of the tragedy is the fact the captain died without realizing his error. He died thinking he was right.
