I’ve flown into the lukla airport before! Did the Everest base camp trek years ago. I remember it took 3 canceled flights before we finally took a helicopter. We landed in the same spot the heli got hit. Amazing place! Fond memories. RIP to those who perished in the accident.
Wow I saw that CCTV crash video all over back when it happened, but with zero context, and I always thought _“How the hell does a big airplane like that just randomly come skidding out of control down some hilly residential street? ....into an idling helicopter, no less?”_ Can’t believe I had no idea I was looking at an airport. That runway really is steep!
There's actually a published procedure for go arounds in Lukla, Jimbo Burgess, an one time instructor for a local airline that flew to Lukla discussed it on his landing video. The closure of flight operations is not only related to shifting wind direction and intensity but also because of rising clouds due to the same. I have seen bright sunny afternoons turn into murky ones within a few minutes while I was there for about a month.
💡 I'll try to offer a solution.... I have _"some"_ personal flying experience, which I'll list here: 👉 1 (assisted)takeoff in a Cessna, from a (flat)runway(with no mountains for 150 miles). Now that we've gotten that out of the way, let's solve this problem! Firstly, there's not a lot of room for "go arounds" in an airport nestled deep inside a small valley surrounded by tall mountains. But the solution is obvious! If the terrain precludes your plane from making horizontal loops while awaiting safer landing approaches, then just do vertical loops!
@@HighlanderNorth1 Once you've taken the vertical gradient of the terrain into account, you'd have to factor in the altitude and particularly the density altitude at this airport (9,334 ft or, 2,845 m) msl. Also, commercial carriers operate very close to the MTOW in Nepal, which leaves almost no room for extra performance at this altitude. As with the most recent CFIT accident involving a DHC-6-300 from Tara Air, there's little or no time to react to the sudden appearance of terrain.
airplanes have propeller blades, not rotor blades. Besides, the AS350 has composite blades that will break off unlike a certain other brand with metal blades that will keep doing damage.
You want to hear one of the worst things I’ve ever seen? 🚁💥🚶♂️ I wouldn’t normally share this but this is “Morbid Midnight”, so.. Okay. I’ve watched a huge amount of shocking videos. But a few years back on a random foreign Instagram, I saw a color CCTV video of large helicopter idling, when some poor soul didn’t see the tail rotor spinning.............. and walked _right_ into it, the rotor striking his skull in the forehead. 😳 It was like a high explosive grenade had detonated. Instantly, a huge light tan-colored cloud was produced. I later realized this peculiar color was that of brain 🧠 matter. As his body continued forward with momentum, the rotor continued to strike deeper and deeper into his head, absolutely obliterating it, until the man collapsed deceased. (This all happened in half a second but I’m describing it blow by blow.) It was for sure the most instant death I have ever seen, more instant than even a gunshot. I’ve never seen or heard about that video since, but holy fucking shit I will never walk near an operating helicopter with anything less than the highest level of caution....
Same question here. It is possible that the thrust lever was in that position trying to counteract the asymmetrical thrust from the left engine, or it normally both thrust levers were at full power and they had retarded the left trying to keep the plane going straight?
Here's what I believe: Nose gear steering was still connected to the pedals (Shown in the video) so when the Captain recognized asymmetrical thrust to the left he mashed the right pedal (brake and rudder) to correct that and re-center on the runway. Unfortunately that steered the plane hard right and that's what caused the plane to go right, not asymmetrical thrust. That's the only explanation I can see.
I guess you'll have to do a video on the recent plane crash in Nepal in a year or two. The video showing what happens in a plane crash was really creepy.
I don't fly the LET. Typically if the right power lever is in the forward position and the left power lever is not, the right engine will produce more thrust/torque. In that scenario, the aircraft will begin to drift to the LEFT, not right. as the left engine (Number 2 engine) is producing more at a higher RPM. Of course there are other factors like propeller blade angle and auto-feathering that I do not know about. If the turboprop is headed for the weeds on the left side of the runway to counteract that the crew will smash the rudder and/or nose wheel steering to the right to compensate. Again, I have never flown the LET which is an Eastern European STOL (Short Takeoff & Land) turboprop. The First Officer (Co-Pilot) having less than 900 hours to total time puts him fairly low for total flight experience as several hundred of those hours would have been gained in the training. Things can go from "routine" to disaster in a fraction of a second when operating any aircraft out on the "edge" of the limits which this airport definitely is.
I’d never get in a plane run by an airline called yeti. Those 72(74 according to some reports I just checked) from last week are another testament to my decision being rational. They routinely make top five most dangerous airlines list.
I was up there trekking when I heard the news of the crash... getting the flight back was more than a little bit nerve-racking, seeing the wreckage still there at the side of the runway
This is good reporting. One tip is that airplanes have propellers, helicopters have rotors. V-22 Osprey tilt rotors have 'prop-rotors', but that is getting ahead of ourselves here.
All things equal, if the right engine was making more power the aircraft would yaw left not right. After watching another vid of the accident I believe the nose wheel was positioned to the right from the beginning of the take-off roll. Advancement of the right engine power lever was in response to the aircraft turning right and not the cause of this accident IMHO. This vid even highlights the nose wheel switch @ 7:38 but no mention of it is made.
Probable Cause The commission concluded that the probable cause of the accident was aircraft's veering towards right during initial take-off roll as a result of asymmetric power due to abrupt shifting of right power lever rearwards and failure to abort the takeoff by crew. There were not enough evidences to determine the exact reason for abrupt shifting of the power lever. Contributing Factors 1. Failure of the PF(being a less experienced co-pilot) to immediately assess and act upon the abrupt shifting of the right power lever resulted in aircraft veering to the right causing certain time lapse for PIC to take controls in order to initiate correction. 2. PIC's attempted corrections of adding power could not correct the veering. Subsequently, application of brakes resulted in asymmetric braking due to the position of the pedals, and further contributed veering towards right.
Yeah, I noticed the pictures as well... found it a tad fishy... It wouldn't be the first time a foot-position issue interfered with an aircraft's performance one way or another... SO while I can't claim expertise on this particular airplane, I CAN suggest that the nose-wheel switch in the picture being on "pedal" instead of "MANUAL" seems to mean that it changes the controls from the rudder pedals to a tiller wheel, so that after the low-speed taxiing is done, it's to be switch for the runway, to prevent rudder from over-compensating a wind issue with a wheel, which can roll a plane right over... AND they didn't do that... I have doubts about this whole "right lever abruptly moving" business. It's forward of the left, suggesting someone tried to use added thrust, but (being a turbo-prop) the engines just didn't have time to spool up thrust before the damage was done... Exactly the kind of "oversight" that can happen when pilots with an already sizeable workload get into a rush... or what some call "Get-there-itis"... The next thing you know, just a tiny bit of toe pressure and the whole take-off roll goes to hell in a handbasket... Sorry to offend anyone here, but evidence speaks on its own to some degree if you just LOOK... AND throughout Asia, there's a dubious habit of sub-optimal investigations, reports, and... if we're honest... safety on airplanes. ;o)
Yeah I’ve never seen that in another post crash investigation before, kinda surprising now that I think about it. But none of those ever had a helicopter rotor come striking through the windshield...
Having flown in and out of this airport I can confirm that it's harrowing. There have been so many accidents here, honestly, I've never been as terrified on a plane in my life than when I was in/out of Lukla. The planes are always old and rarely serviced correctly. Plus I'm sorry to say this, but Nepalese air safety isn't what it should be; Yeti is absolutely notorious for being poor with their safety record. There are so many accidents here due to the short and steep runway, the mountains and terrain, the weather and also because pilots landing here usually have to rely on non-electrical/sight based flying on account of the regular power cuts in the region. Honestly, I wouldn't recommend Lukla airport at all.
"The planes are always old and rarely serviced correctly. Plus I'm sorry to say this, but Nepalese air safety isn't what it should be; Yeti is absolutely notorious for being poor with their safety record. " Where do you get this BS from? Let's see you provide some verifiable statistics that prove your claims. There are over 1100 flights per year into Lukla from Kathmandu and the vast majority arrive without incident. The flights are ALWAYS sight based ( Visual Flight Rules (VFR). So what? The pilots are highly skilled and the planes always go through regular maintenance checks. Apparently your plane and pilot got you home. My pilot took off on a muddy grass field. I flew out of Lukla before the asphalt was installed on the runway. Wasn't scary at all.
Differential thrust with higher power to the right engine would have turned the plane left, not right. Was the rightward departure cause by an attempt to counteract that via steering input?

@@driveman6490 I would think the full power on right side was an attempt to keep the plane from veering right. I’ve been up flying my 182 when my right seat passenger decided to stretch and full depressed the right rudder. If something like that happened, it would be tough to correct. I also flew a Mooney once that had a tendency to have the left brake stick. My partner hit a taxiway light and he thought it was his fault, but because I had experienced the left pulling tendency, I don’t think it was all his fault. It would help if that airport had at least some taxiway to do a proper preflight. Also, if it were me, my first turn out of parking would be right to use every inch of runway.
Good video and analysis. Just a minor suggestion: I wouldn't call the the propellers of a fixed wing aircraft as "rotors". The term rotor is generally reserved for the main rotor and the tail rotor seen in helicopters.
Imagine that you're flying somewhere in Asia and for some reason the pilot is forced to make an emergency landing and chooses this airport. Then you remember your comment and realize that fate is a bitch.
is it me or is watching this channel making me want to be a mountaineer and also go to lukla and the fact that i can’t stop thinking about all these disasters and wanting to know more is making me smarter and more interested in these kinds of vids.
That last photo shows what happened. Someone had their toes on the right brake and it was locked up. I've seen it before, a student pilot came in to land on half of the cross runway at YAMB with a slight tail wind (this was due to F-111's using the main runway). Dude had his toes on the brakes, locked up one wheel and in order to skid straight he locked up the other wheel. End result, off near the grass and two blown main tyres/tires. Took about 10 of us to carry the Piper Tomahawk off the runway and onto the grass.
I think it's worth mentioning that there have been incidents of propellers going into the beta range un commanded on Let 410 aircraft. If this occurs on one engine there would be an asymmetric thrust issue resulting in the aircraft veering left or right. In this case it seems the right engine was the problem. They added right engine thrust to try and control the aircraft...possibly a bit too late, or the prop did not respond increasing the thrust. The other issue with the L410 is lack of rudder authority which would have compounded their problem by not allowing them to counteract the asymmetric thrust.....In any case a tragic loss of life at a dangerous airport.
Imagine those security guards, just chillin until you see a plane coming right towards you and chopping you up to death and running over you. Must’ve been horrifying to watch too.
You have made a few omissions that make a big difference to your story. Yes, the RH power lever was further forward than the LH, but this is NOT what caused the aircraft to veer to the right. The Co-pilot who was carrying out the takeoff advanced both power levers forward for the takeoff. For some reason he did not leave his hands on the throttle levers as is the custom. This is to ensure they don't move rearward on their own, which can happen and unfortunately, on this flight it did happen. As the RH throttle moved backwards the RH thrust reduced causing the aircraft to veer right as the LH engine was still at takeoff power. The Captain, seeing this unfolding took control and pushed the RH throttle lever forward (as seen in the photos) in an attempt to control the RH swing. Sadly, turbo prop engines take a while to spool up the power and it was not possible to arrest the RH swing.
You also made a mistake by saying the police officer was struck by the rotor blade of the plane. They don’t have rotor blades. Also the throttles are just that and not thrusters this isn’t Star Trek
Had to fly in and out of this airport recently. The single most terrifying moment of my life was the flight in. And I surround myself with death regularly. Never again.
I just looked at my photos from Nepal and saw that the helicopter I took from lukla to Kathmandu after my base camp trip in may 2018 was the same one that got hit (First one).
It must have been going left, then over corrected with right brake, to make such a radical turn on a short runway. Also, they were in a hurry, did they take time to get centered and spin up in preparation for takeoff?
Another thing to note, the path of the plane was always on going to the right, correction to more thrust for right engine could've been to counteract it whilst having enough power to take off. However, the captain must've noticed this rightward direction and tried to take control. It might then have had a possible dual input scenario, if its possible on the ground. For why the sudden right turn, they must've panicked and done something else wrong.
Airoport must be renovated at least. Landing strip is too tiny and short. Pretty scary shit when you see what professionalism it requires for landing and anyway it's not enough for safty if the weather conditions are not too good.
Hang on. In photo right throttle is set to full pwr. Normally that would turn the plane left. But they went right. Are you sure it wasn’t that right engine failed to come up, so the copilot firewalled it? Maybe there’s more to the story, but in any case he didn’t just attempt to add power on one side for no reason. Doesn’t it seem like the plane here, not the crew?
I am a private pilot and have landed at this airport as a passenger and believe me! it takes nerves of steel to even be a passenger especially when you know exactly everything that can go wrong during the approach and landing ( a controlled crash) is more of the correct word for this landing..
If the right engine was shifted to full power then why did it veer off to the right? If the differential thrust was on the right side the plane it would have veered to the left in the opposite direction. Am I missing something? Those levers may represent the prop feathering system and if that is the case if he accidently feathered the right side prop that would then make the left side produce more thrust then the right and cause the crash. Those are not the throttle quads you show in the video, they control the feathering of the blades.
Unbelievable to hear that the officer actually survived the accident for a awhile. Most people would be pronounced dead immediately for... lots of reasons.
The government should look into making this airport better and safer, because tourism is such a big thing and people should not be scared to go there just because of safety issues
This video is a bit of a factual disaster; fixed-wing aircraft don't have rotors, they have propellers; throttle levers aren't called "thrusters", and as several have already pointed out below, having the right throttle advanced significantly ahead of the left would indeed create asymmetric thrust, but it would yaw the aircraft left, not right. Dude needs to get his facts straight and actually understand a little about his subject before posting videos like this. That said, the scene at 7:45 with all the blood and particulate matter on the cockpit panel is pretty chilling.
I'm not claiming to be a pilot or expert but if the right engine was at full power and the left engine was at half power wouldn't the aircraft pull extremely & uncontrollably to the left ?
For a show about an aircraft disaster I wonder how you got propellers confused with rotors. I watched a vid on Lukla yesterday and it was stated only captains have permission to fly in and out of there. A second officer should not have been in charge. The left and right engine throttles as found after the crash were contradictory to how the plane would have behaved, you got that wrong.
My understanding is that when the ca handed the plane over to the fo, the nose wheel was canted to the right unfortunately. Procedure is to stand on the brakes, add full power and then release the brakes. If course the plane veered to the right immediately. Looks like one of the pilots reduced power to the left engine.. But was too late. Distance from the edge of the runway to the dropoff.. Maybe about 5ft.
He's copying the channel chills, who actually has a speech problem, tons of RUclipsrs are faking it on purpose because they think it's cool and makes them unique 😂
This airport is an accident waiting to happen so no surprises there. I expect that most of the passengers accept the risk in the same way as they accept the risk of dying on a mountain.
5:38 - BRUH. After the plane collides with the helicopter 🚁, peep the bottom right quadrant and the people there scattering. A large piece of debris is hurling towards ONE unlucky man who saw the wreck and ran for his life. In the process attempts to jump over a suitcase only to be met mid-air with said debris(maybe a door? Lols).
Why would the plane veer to the right if the right engine thruster was shifted to full power? Seems that would speed up the right side of the plane causing it to rotate to port.
This makes no sense The abrupt shifting of right thruster would yaw the plane to the left. I think you mean left thruster was shifted . This 1st officer forgot he was in a twin and only used 1 throttle !!!!!
There seems no role of asymmetric thrust, something like wind, or uneven patch of runway made pilot feel, his plane is going left, he panicked, and pushed right thruster to max, but it didn't correct cuz thruster wasn't playing any role, something mechanical like stuck steering or boken steering column....
I made a bit of a mistake on the subtitles for Captain Rokaya, he was not 118 years old, and was actually 48 years old. Not quite sure how that one happened or how I missed it 😅😂my goof guys!

There have been so many accidents here, honestly, I've never been as terrified on a plane in my life than when I was in/out of Lukla. The planes are always old and rarely serviced correctly. Plus I'm sorry to say this, but Nepalese air safety isn't what it should be; Yeti is absolutely notorious for being poor with their safety record.
There are so many accidents here due to the short and steep runway, the mountains and terrain, the weather and also because pilots landing here usually have to rely on non-electrical/sight based flying on account of the regular power cuts in the region. Honestly, I wouldn't recommend Lukla airport at all.
"The planes are always old and rarely serviced correctly. Plus I'm sorry to say this, but Nepalese air safety isn't what it should be; Yeti is absolutely notorious for being poor with their safety record. " Where do you get this BS from? Let's see you provide some verifiable statistics that prove your claims.
There are over 1100 flights per year into Lukla from Kathmandu and the vast majority arrive without incident. The flights are ALWAYS sight based ( Visual Flight Rules (VFR). So what? The pilots are highly skilled and the planes always go through regular maintenance checks. Apparently your plane and pilot got you home.
My pilot took off on a muddy grass field. I flew out of Lukla before the asphalt was installed on the runway. Wasn't scary at all.
Very interesting, you do a lot of research! Excellent channel.
I've seen this unique runway many times through watching numerous documentaries on Mt. Everest. I am amazed there are not more crashes here.
Wow!! Such a great & informative video ‼️
God bless all of them, Thanks for the report.
Differential thrust with higher power to the right engine would have turned the plane left, not right. Was the rightward departure cause by an attempt to counteract that via steering input?
I checked Aviation Safety Network’s entry on this accident. It states that the right throttle lever was accidentally pulled back.
Probable Cause
The commission concluded that the probable cause of the accident was aircraft's veering towards right during initial take-off roll as a result of asymmetric power due to abrupt shifting of right power lever rearwards and failure to abort the takeoff by crew. There were not enough evidences to determine the exact reason for abrupt shifting of the power lever.
Contributing Factors
1. Failure of the PF(being a less experienced co-pilot) to immediately assess and act upon the abrupt shifting of the right power lever resulted in aircraft veering to the right causing certain time lapse for PIC to take controls in order to initiate correction.
2. PIC's attempted corrections of adding power could not correct the veering. Subsequently, application of brakes resulted in asymmetric braking due to the position of the pedals, and further contributed veering towards right.
@@driveman6490 I would think the full power on right side was an attempt to keep the plane from veering right. I’ve been up flying my 182 when my right seat passenger decided to stretch and full depressed the right rudder. If something like that happened, it would be tough to correct. I also flew a Mooney once that had a tendency to have the left brake stick. My partner hit a taxiway light and he thought it was his fault, but because I had experienced the left pulling tendency, I don’t think it was all his fault. It would help if that airport had at least some taxiway to do a proper preflight. Also, if it were me, my first turn out of parking would be right to use every inch of runway.
Aircraft have Propellers not Rotors. Helicopters have Rotors!!!!!

Good video and analysis. Just a minor suggestion: I wouldn't call the the propellers of a fixed wing aircraft as "rotors". The term rotor is generally reserved for the main rotor and the tail rotor seen in helicopters.
Damn those photos from the cockpit are...gnarly 😮
Great video. Always look forward to watching every week.
And this folks, is the reason choppers were invented. 🤷🏾🚁
I don't know where I will die
But I know it won't be at that airport
Imagine that you're flying somewhere in Asia and for some reason the pilot is forced to make an emergency landing and chooses this airport. Then you remember your comment and realize that fate is a bitch.
For me, it won't be in a plane period
@@mergingtrout3717 touché
I flew into Lukla before....its EXACTLY as sketchy as it seems here. Amazing airport.
is it me or is watching this channel making me want to be a mountaineer and also go to lukla and the fact that i can’t stop thinking about all these disasters and wanting to know more is making me smarter and more interested in these kinds of vids.
Another excellent presentation. Thank you!
That last photo shows what happened. Someone had their toes on the right brake and it was locked up. I've seen it before, a student pilot came in to land on half of the cross runway at YAMB with a slight tail wind (this was due to F-111's using the main runway). Dude had his toes on the brakes, locked up one wheel and in order to skid straight he locked up the other wheel. End result, off near the grass and two blown main tyres/tires. Took about 10 of us to carry the Piper Tomahawk off the runway and onto the grass.
I think it's worth mentioning that there have been incidents of propellers going into the beta range un commanded on Let 410 aircraft. If this occurs on one engine there would be an asymmetric thrust issue resulting in the aircraft veering left or right. In this case it seems the right engine was the problem. They added right engine thrust to try and control the aircraft...possibly a bit too late, or the prop did not respond increasing the thrust. The other issue with the L410 is lack of rudder authority which would have compounded their problem by not allowing them to counteract the asymmetric thrust.....In any case a tragic loss of life at a dangerous airport.
The airport in Telluride Colorado seems even more sketchy than this one if that's possible.
118 year old pilot in the subtitles??
Thanks for the very interesting upload 👍
Yah, he addressed it in his pinned comment : ) Cheers!
Imagine those security guards, just chillin until you see a plane coming right towards you and chopping you up to death and running over you. Must’ve been horrifying to watch too.
How many times did it take you to get those names right? Lol Good video Broseph!
Yeah I was impressed with that!
Great video. Hopefully you’re able to do more plane accidents
You have made a few omissions that make a big difference to your story. Yes, the RH power lever was further forward than the LH, but this is NOT what caused the aircraft to veer to the right. The Co-pilot who was carrying out the takeoff advanced both power levers forward for the takeoff. For some reason he did not leave his hands on the throttle levers as is the custom. This is to ensure they don't move rearward on their own, which can happen and unfortunately, on this flight it did happen. As the RH throttle moved backwards the RH thrust reduced causing the aircraft to veer right as the LH engine was still at takeoff power. The Captain, seeing this unfolding took control and pushed the RH throttle lever forward (as seen in the photos) in an attempt to control the RH swing. Sadly, turbo prop engines take a while to spool up the power and it was not possible to arrest the RH swing.
I see the problem: the pilot was 118 years old.. acording to the text on the video at 4:02
“Lack of roads in the region”! Make that absence of roads in the region, there are none.
A bit sobering seeing all the blood spatters over the cockpit. RIP to those involved
Unfortunately, it looked like the helicopter's rotor came right through the co-pilots window
You also made a mistake by saying the police officer was struck by the rotor blade of the plane. They don’t have rotor blades. Also the throttles are just that and not thrusters this isn’t Star Trek
I love that the airline is Yeti Airlines!
Looked like two people got smeared by the plane and then smeared into the helicopter. Awful surprise to have.
Had to fly in and out of this airport recently. The single most terrifying moment of my life was the flight in. And I surround myself with death regularly. Never again.
This is the type of "airport" that really should only be serviced by helicopters
Exactly! 🚁
I just looked at my photos from Nepal and saw that the helicopter I took from lukla to Kathmandu after my base camp trip in may 2018 was the same one that got hit (First one).
happened a couple of weeks before my Mera PaRk trek - the wreckage was still by the side of the runway - making for and uneasy landing and take off
Minor correction. Panes have "Propellers"not "Spinning Rotors".
It must have been going left, then over corrected with right brake, to make such a radical turn on a short runway. Also, they were in a hurry, did they take time to get centered and spin up in preparation for takeoff?
>Samir pay attention I am begging you, you are breaking the plane!
Mt. Everest should be renamed Mt. Trash. Sad how cluttered it is.
Another thing to note, the path of the plane was always on going to the right, correction to more thrust for right engine could've been to counteract it whilst having enough power to take off. However, the captain must've noticed this rightward direction and tried to take control. It might then have had a possible dual input scenario, if its possible on the ground.
For why the sudden right turn, they must've panicked and done something else wrong.
Airoport must be renovated at least. Landing strip is too tiny and short. Pretty scary shit when you see what professionalism it requires for landing and anyway it's not enough for safty if the weather conditions are not too good.
why would thrust from the right engine cause the aircraft to veer to the right? thrust from the right engine would push it left?
Hang on. In photo right throttle is set to full pwr. Normally that would turn the plane left. But they went right. Are you sure it wasn’t that right engine failed to come up, so the copilot firewalled it? Maybe there’s more to the story, but in any case he didn’t just attempt to add power on one side for no reason.
Doesn’t it seem like the plane here, not the crew?
I am a private pilot and have landed at this airport as a passenger and believe me! it takes nerves of steel to even be a passenger especially when you know exactly everything that can go wrong during the approach and landing ( a controlled crash) is more of the correct word for this landing..
If the right engine was shifted to full power then why did it veer off to the right? If the differential thrust was on the right side the plane it would have veered to the left in the opposite direction. Am I missing something? Those levers may represent the prop feathering system and if that is the case if he accidently feathered the right side prop that would then make the left side produce more thrust then the right and cause the crash. Those are not the throttle quads you show in the video, they control the feathering of the blades.
That's almost an aircraft carrier landing
Unbelievable to hear that the officer actually survived the accident for a awhile.
Most people would be pronounced dead immediately for... lots of reasons.
No VASI (visual approach slope indicator)!
No go-arounds!
Violent crosswinds!
High stakes for sure!
The government should look into making this airport better and safer, because tourism is such a big thing and people should not be scared to go there just because of safety issues
Sure...we should blow up the mountains and make a level 5000 ft runway to land 747's. Great idea.
This video is a bit of a factual disaster; fixed-wing aircraft don't have rotors, they have propellers; throttle levers aren't called "thrusters", and as several have already pointed out below, having the right throttle advanced significantly ahead of the left would indeed create asymmetric thrust, but it would yaw the aircraft left, not right. Dude needs to get his facts straight and actually understand a little about his subject before posting videos like this.
That said, the scene at 7:45 with all the blood and particulate matter on the cockpit panel is pretty chilling.
I'm not claiming to be a pilot or expert but if the right engine was at full power and the left engine was at half power wouldn't the aircraft pull extremely & uncontrollably to the left ?
For a show about an aircraft disaster I wonder how you got propellers confused with rotors. I watched a vid on Lukla yesterday and it was stated only captains have permission to fly in and out of there. A second officer should not have been in charge. The left and right engine throttles as found after the crash were contradictory to how the plane would have behaved, you got that wrong.
It's a great flight to take very exciting. Don't be put off visiting kumbu.
Asymmetrical thrust just saw this as a possible cause in a recent plane crash in the snowing conditions.
One would think they’d do static takeoffs from that runway. Run up the thrust, check gauges then release brakes. 🤔
Correct my if I'm wrong but if you add power to the right engine the aircraft should go left not right.
this airport should not even exist.
um, ya, there is a go around procedure. Look it up.
My understanding is that when the ca handed the plane over to the fo, the nose wheel was canted to the right unfortunately. Procedure is to stand on the brakes, add full power and then release the brakes. If course the plane veered to the right immediately. Looks like one of the pilots reduced power to the left engine.. But was too late. Distance from the edge of the runway to the dropoff.. Maybe about 5ft.
Very informative but the narrator has a monotonous tone. Nonetheless, I can see how this airport presents many hazards
He's copying the channel chills, who actually has a speech problem, tons of RUclipsrs are faking it on purpose because they think it's cool and makes them unique 😂
This airport is an accident waiting to happen so no surprises there. I expect that most of the passengers accept the risk in the same way as they accept the risk of dying on a mountain.
I'm so sorry.
Would a right engine producing more thrust cause the plane to move to the left...not right?
Very difficult airport.
Huge crash at Pohkara about a week ago.
How does a guy with 165 hours find himself in the right seat of a twin flying a dangerous route like this one?
My name is Lukla, I live on the 2nd floor
2 people killed and 3 named? A fourth dead in Kathmandu hospital? Good video with candid footage anyway
2 died on scene and a 3rd died in the hospital.
@@MorbidMidnight Not what you stated in the video.
@@curbyourshi1056 he absolutely does maybe watch whole video
@@kneesocks15 I go by initial reports, they absolutely so initially say that in the video.
@@kneesocks15 5:55
5:38 - BRUH. After the plane collides with the helicopter 🚁, peep the bottom right quadrant and the people there scattering. A large piece of debris is hurling towards ONE unlucky man who saw the wreck and ran for his life. In the process attempts to jump over a suitcase only to be met mid-air with said debris(maybe a door? Lols).
u think he died or nah?
Planes don’t have rotor blades. Or thrusters. Where are getting these term?
Chunks on the dash
Planes have props. Helicopters have rotor blades.
Why would the plane veer to the right if the right engine thruster was shifted to full power? Seems that would speed up the right side of the plane causing it to rotate to port.
Shouldnt the plane move towards left when right engine thrust is increased ?
thanks.
This makes no sense
The abrupt shifting of right thruster would yaw the plane to the left.
I think you mean left thruster was shifted .
This 1st officer forgot he was in a twin and only used 1 throttle !!!!!
You can't even get your commercial license until you have 1500 hrs. what was he doing in that airplane as crew????
There seems no role of asymmetric thrust, something like wind, or uneven patch of runway made pilot feel, his plane is going left, he panicked, and pushed right thruster to max, but it didn't correct cuz thruster wasn't playing any role, something mechanical like stuck steering or boken steering column....
