On the morning of July 6, 2013 a #boeing 777-200ER from #Asiana Airlines is on approach to runway 28L in #SanFrancisco. Everything seems fine in the cockpit as the aircraft descends down. It soon becomes apparent that #flight241 is too low on the glideslope but by the time the flight crew notices this, it's too late. Why did The pilots continue? Why was this not noticed sooner and why did the #autothrottle system not activate? Let's investigate...

Happy Halloween Peter, I wish you and the family 🎉. you wrote to me by email that you would possibly post a video before the turn of the year about the terribly tragic Air France 447 2009 accident.

But as I said, I hope this video comes before the turn of the year. “Happy halloween Peter , önskar jag till dig och familjen 🎉. du skrev till mig på mail att du skulle eventuellt lägga upp video innan årsskiftet om den fruktansvärt tragiska Air France 447 2009 olyckan .

As a retired 777 Captain, I am familiar with this accident. Once again your explanation and depiction of what happened is magnificient. This crew had many opportunities to go-around and never chose to do so. No justification whatsoever for what happened. When you go-around it takes longer to get to the gate and you make more money. There is no motivation to be a hero and land out of a bad approach.

[@carbon1255]

The justification on the part of the Captain was to pass his line check and the workload. Ideally, the 3rd pilot should have called the go around due to the workload, but they were all reliant on the aircraft keeping speed.

[@mikefendel]

A go-around is not a failed approach. A go-around is the proper corrective action of a failed approach. Anyone recognizing aircraft condition that is beyond acceptable parameters should be required by company policy and regulation to call out clearly “GO-AROUND”.

I’m guessing that this incident had most of the crew and passengers survive because of the low speed and relatively slow decent rate. Being the end of the flight, the plane probably had much less fuel in it. That being said, I can only imagine what it must have felt like to be those that were ejected out the back when the tail broke off. I’m happy for those that survived… but the amount of lasting mental and physical trauma from something like that would probably be career ending for most.

Two corrections. 1: According to the San Mateo County Coroner's report, the student lying in grass near the runway was alive when she was run over by a fire truck. Tragically she was killed by the fire truck. 2: Per helmet and truck videos from the scene, she was initially not covered in firefighting foam. One or more firefighters saw her prior to the foam application and waved a truck around her, assuming she was deceased. A maneuvering truck ran her over a short time later. Her name was Ye Mengyuan and she was 16 years old. Respectfully, the video should be corrected.

[@kadrikarakoc807]

[@gregsomlai297]

On July 19, 2013, the San Mateo County Coroner's office determined that Mengyuan was still alive before being run over by a rescue vehicle, and was killed by blunt force trauma. On January 28, 2014, the San Francisco city attorney's office announced its conclusion that the girl was already dead when she was run over. It's beyond horrible, but I hope that the latter conclusion is correct. Because otherwise it's even more horrible.

First thing I did was turn on the TV and there it was, the accident. Lucky that most of the people escaped safely, I can only imagine what the ATC had to deal with for the remainder of the day. Our 14hr flight turned into 26 hours inside the aircraft due to taking off with minimum fuel for the only available shorter runway, then going to Seattle for refueling. Surprisingly it was the quietest longhaul flight ever, I think the pax were so terrified and exausted with all the delays, we all just wanted to get home.

[@MikkoRantalainen]

It's interesting that Asiana had company policy to use autopilot at all times possible but still the training didn't result in full understanding of the various autopilot modes. I would have assumed that with such a heavy emphasis on autopilot, fully understanding the autopilot behavior in all modes would be critical.

[@MentourPilot]

Yes, but it’s always an issue when the pilots THINK they understand something but they really don’t. Those knowledge gaps are only exposed in very peculiar situations, like this one..

[@JeanClaudeCOCO]

Most people don’t always remember fully what they learn in school so for Asiana to opt for autopilot in all times is surely one way to be over reliant on something and not emphasizing manual or on going training as a reference point is really bad policy. The rigidity of their leadership structure also played a role in this fatal outcome. If line of communication had been open and not closed the instructors would have step in and avoided this and the pilot would have been sent to more training courses. Clearly he wasn’t ready for the 777.

[@chnet968]

@@JeanClaudeCOCO I think the instructor should have intervened earlier, either overtaking the control and/or call out go around. Even on driving lessons on car, if the instructor sees any sign from the learner that leads him to believe continuing practice driving on the road is unsafe, he would have to tell the learner to stop the car, swap the seats, and have the instructor driving the car back to the driving school.

[@hubertbrunner2915]

I agree. In my career I have come across so many pilots who only used V/S as other modes like FLCH and VPath/VNAV modes especially in association with A/T where not clearly understood. It got worse after the introduction of fully automated GPS approaches followed by ATC shortcuts and subsequent visual clearances when the approach then had to change to managed mode and/or subsequent visual clearances.

[@philipjamesparsons]

Airlines like to talk about having pilots understand automation. From my experience of three Boeing aircraft, I don't think that the design engineers truly understood automation themselves. Many times have I seen these aircraft doing things that cannot and should not happen when flying on automation. If you are wondering what the heck the automation is doing, use a lower level of automation or fly manually if your skills are still up to it.

[@billakers6082]

SFO approach control always keeps you high and fast due to San Jose, Oakland air traffic and volume of arrivals. You have to be ready for the slam dunk because it's coming.

As a pilot I would like to say that it doesn't matter what kind of speed protection is available in an airplane in the way you operate the airplane. It is the pilots responsibility to fly a safe airspeed, no matter what. The speed protection system is a last defense against stalling, it is not the other way around. The most important thing is what Mentour also said: keep flying manually, also with A/T disengaged from time to time!

PF also was worried about passing his line training rather than safety alone, might be reason for no go around despite being the only one to know the true gravity of the situation. 90% PF’s fault I’d say. 10% instructor and RF. They can’t know until it’s communicated, they’d have to be super super tuned in to notice. Considering 10 hours of smooth flying, circadian low, and lack of communication, you can’t put the blame on instructor and RF.

See, the whole point is that Asiana taught them to rely on automated systems as much as possible, and in fact, you can see this in the world of cars, too. There are Tesla drivers who have been _killed_ because they let the car drive itself, thinking it was fully 100% equipped to handle everything without the "driver" (or, rather, passenger-behind-the-wheel) needing to monitor anything. In both cases, this is _not_ what the designers of these vehicles intended. Just like with the Tesla, aircraft will have auto-pilot, but as the pilot flying, it is still one's responsibility to monitor the state of the aircraft and be aware of what it's doing at all times instead of just assuming the computer is functioning properly, or in this case, as intended.

Unfortunately, I was at SFO that day and watched this accident happen in real time. It was a gorgeous day and I had just dropped a friend off at the airport and decided to do some airplane watching from the observation deck. I had been watching planes land and take off for about 30 minutes when I caught eye of the Asiana flight. From my perspective I could not tell anything was wrong until the impact with the sea wall. I watched the impact and the airplane tumble down the runway. I was using my binoculars and also my telephoto lense on my camera. It was terrible to witness and at first I thought I could not believe what I was looking at. To witness a commercial plane of that size crash and almost cartwheel down the runway was unbelievable. I stood there in disbelief with other people who were plane spotting and watched the emergency response to the accident. A SFO police officer came to the platform and asked if any of us saw the accident and, of course, we all did. We were asked to write a statement of what we witnessed and to provide any photo documentation or recordings of the accident which I gladly complied with. It was a sad and tragic ending of what was a beautiful day in the Bay Area and I found myself not able to concentrate for days afterward.

I’m 43 years old and have been terrified of flying all my life and have never been in an aeroplane at all. I started watching your videos and due to the information you give and a very supportive other half I took my first holiday on a plane last year (2 hour flight). I’ve now been on holiday 4 times on planes so cannot thank you enough for giving me the confidence and freedom to fly; you have changed my life. My last flight was the longest I have been on 4 hours from Turkey to England on a 737-800. On that flight home I was on row 2 and saw the pilot leave the cabin and talk to the cabin crew, get some snacks and re-enter the cockpit. While I’m cruise I’m now really relaxed as from your videos I understand that being high up gives us options should anything happen. However when the captain did this I became nervous again as I remembered what happened on the German wings flight many years ago where to do-pilot locked everyone out of the cabin with disastrous consequences. What has changed from a procedure process to protect against this reoccurring? Many thanks

[@mehmettufan7914]

After germanwings accident ,airlines put some extra rules to their cockpit procedures. When one of the pilots wants to use toilet or lieve the cockpit to stretch the legs for example, there must be a cabin crew inside the cockpit during flight crew absence.

[@Powerranger-le4up]

Though Germanwings probably could’ve been prevented had people learned from the crash of LAM Mozambique Flight 470 where the captain locked out the first officer and done the same thing. Ironically, LAM already had that policy of having a flight attendant come in when one needed to leave the cockpit. It just wasn’t followed the day of that crash. Germanwings didn’t have that policy at all until that crash.

AFAIK, the most important point was to enhance the monitoring of the mental status of pilots, both at the time of employment and during the career.

We must trust a lot of people in society, we cannot have someone monitoring everyone who has a job where he easily could cause fatal harm. The truck driver should not suddenly drive on the sidewalk.

Regarding the controversy about a passenger being run over: this happened as the airport firetruck was maneuvering to aggressively fight the fire due to a lack of clarity if passengers were still on board the aircraft. There were several feet of foam now surrounding the aircraft, obscuring the previously visible body, which unfortunately was run over. It may not have been marked with a cone due to how quickly it became covered and how close it was to the flaming aircraft on arrival of this truck. Autopsy found a lack of dust, smoke, water, or foam in the lungs of the victim, indicating her death preceded the arrival of firefighters. Of note, the two ejected fatalities were the only two passengers not wearing seatbelts. Even if injured, you can survive this severity of impact in a modern plane....but not if you get thrown hundreds of feet down the runway.

I flew the 787 as a Captain based in KSFO for several years. The 787 is very, very similar to the 777 and the training to move from one to the other is a short course primarily focused on differences and limitations. Our procedures prohibited the use of Flight Level Change (“FLCH”) below a certain altitude. The HOLD mode was well understood but there were still several recorded incidents in which FLCH and HOLD were used. This accident changed everything. The recalcitrant pilots that had flown older aircraft had been holding on to “Level Change” and “Vertical Speed” (“VS”) and seemed to have a great reluctance to use the latest technology to use LNAV and VNAV modes. In fact, among those of fully bought in to the GPS based LNAV/VNAV paradigm, the “V/S” was short for “Very Seldom” as was something that we typically were reluctant to use because of the lack of speed protection. FLCH was generally considered to be a mode that carried a number of threats and was only used with a high emphasis on strict CRM protocols. The Vertical Navigation mode provided all of the speed protections as long as the Auto Throttles were left engaged. This accident is a case study in poor training, a lack of system knowledge and awful CRM. My briefing about missed approach was that any pilot or qualified jumpseater should not be reluctant to call for a missed approach. The third pilot was probably the only one with complete situational awareness and should have called for a missed approach the moment he pushed up the throttles. Such a waste.

Of course, that likely means that your body is less responsive to the external influence of blue light and so on that help adjust us to a shorter cycle and induce sleep but there are many other influences too.

The weight and drag of the right landing gear being gone forces KLM 4805 to roll to the left, and Pan Am 1736's vertical stabilizer slashes the underside of KLM's own left wing like a razor, severing hydraulic lines and ripping through the outboard fuel tank. Once clear of the Pan Am jet, KLM 4805's left wing almost hits the ground, and only full right rudder from Captain van Zanten manages to save it. The plane nearly stalls as it lifts off, due to the damage to the left wing, and is again saved just in time. Onboard Pan Am 1736, the clock is ticking. The first class lounge has been ripped open, but the main cabin is still sound. It's only a matter of time, however, before the fire eating its way through KLM's jet-fuel-soaked landing gear climbs to the stub of the left wing-and from there, to the fuselage and central fuel tank, spelling doom for the 300+ people on board. To make matters worse, a second fire breaks out in the remnants of the upstairs lounge, caused by sparking severed electrical wires. Most of the passengers are elderly, and the emergency exits on the left side of the aircraft are unusable. For the crew, this will be the evacuation of their lives. Six minutes after takeoff, the first MAYDAY call from KLM 4805 comes in-and for the first time, the Los Rodeos tower realizes to their horror that not one but _two _planes were in distress. The KLM flight crew, only just beginning to realize the extent of the damage to their plane, initially wanted to circle back and land at Los Rodeos-but Los Rodeos has only one runway, and between the burning wreck of Pan Am 1736, its evacuating passengers, the fire trucks, the ambulances, and their own ruined landing gear, that runway was completely unusable. They could either try for Las Palmas, or ditch in the sea. As KLM 4805 acknowledged the transmission, the ATC crew could hear the unmistakable sound of an uncontained engine failure. Engine no. 1 had ingested part of Pan Am's vertical stabilizer, damaging the fan disc beyond salvation. In the KLM cockpit, a grim mood reigned as the flight crew saw the enormity of the task in front of them. Engine no. 1 had failed and was spitting flame. Their left wing was bleeding jet fuel-fuel that could ignite at any time. Because of the severity of the tailstrike they had endured while rotating early, the crew was unable to pressurize the plane. Once at Las Palmas, they would have to belly-land their massive airliner, as their right main gear was completely gone. And, to top it all off, pressure in three out of their four hydraulic lines was steadily dropping. Soon, their aircraft would be all but uncontrollable. Captain van Zanten felt a cold chill run through him as he realized what he'd done. He had been rushing to get home to his wife. Now, he might never see her again-and his recklessness might have doomed hundreds of people to a fiery end. Somehow, he would have to fly his barely-controllable massive airliner to Las Palmas and belly land it. Soon, that cold chill was replaced by determination. He had gotten them into this mess, and he would get them out of it. If anyone could do it, it was him-one of the best pilots in KLM. And if he died, that would be alright-so long as his passengers and crew didn't have to pay for his mistake. They were going to Las Palmas. And all because of a broken fuel truck.

@@starwarzchik112 and don't forget that if PanAm had taken their assigned exit from the runway they'd not have been there when KLM was taking off. Had they called in their decision to not take their assigned exit KLM would have waited. Had the tower crew known that the exit they assigned to PanAm was suboptimal for a 747 they'd have assigned another exit and not authorised KLM. Had ATC procedures been the same at Tenerife as at Schiphol van Zanten would not have misunderstood the permission to line up as permission to take off (at Schiphol those were always the same, when given permission to enter the runway you have permission to take off unless explicitly told otherwise). Had the tower crew not been distracted by the football match on the radio they might have been more observant. Had there not been overcrowding at the airport because of a lot of diversions due to bomb threats at other airports PanAm would not have been there at all. Had the weather been different the tower crew and the KLM crew would have seen the PanAm aircraft still on the runway. That accident was such a bucket list of bad things happening all at once, yet still van Zanten is vilified for it despite doing everything according to his training and experience, when IMO the main direct culprit was the PanAm crew who failed to notify ATC of their decision to use a different runway exit from the one they were assigned. But as so often there's not a single factor that was solely responsible, nor a single person. Everyone involved made mistakes, whether through complacency, lack of experience, overconfidence, or distractions is irrelevant to the final outcome and only important to the people making recommendations to prevent similar accidents happening in the future (which after Tenerife meant mainly worldwide standardisation of ATC phraseology and procedures, and probably a more rapid introduction of ground radar at fog prone airports. And all of that failed to prevent a very similar accident (though luckily with less loss of life because the aircraft were smaller) at Milan Linate years later when a SAS MD80 series airliner taking off slammed into a business jet that had entered the runway without permission, again in fog, after getting lost on a taxiway.

[@richardprasad6810]

Thank you for this. I remember the first thing that I thought when watching this accident was how 3 experienced pilots in the cockpit all failed to recognize the approach was low and slow - it seemed like the most basic error, something that struck me from what I remember in my PPL lessons 25 years ago, compounded by the pilot flying pulling up without increasing power. But your explanation explained the chain of events and errors that led to the descent going wrong so clearly. You also explained the technical aspects of the way the B777 systems so well, and how they contributed to this sequence of events - this was exceptional. So much I want to ask, I want so much more detail. From the media here in Korea, couple things I remember from the aftermath - there was a lot of talk from Asiana about how the ILS approach was not operating, but also that the autothrottle had not worked properly - if I remember right, this was also something that the flight crew all mentioned in interviews after the accident. The detail you shared about the training session which did not adequately explain what protections the autothrottle actually offered, and the misconceptions the pilots were left with (not realizing the protection they were counting on did not exist in certain modes) was really telling. Discussion on pilot forums after the crash mentioned the way both major Korean airlines relied so much on automation. I remember reading an account of a foreign training captain working here who failed a senior Korean captain on a simulator flight for not being able to handle a visual approach, requesting vectors etc. because of this reliance. It was known here that the PF had very few hours on the B777, but your little detail about how he was apprehensive about flying a visual approach on his first line check was striking. You also handled the issue of the hierarchical culture that exists here very well - I have lived here for so long, and it really was/is a powerful force everywhere (business, medicine, law) and I can only imagine way this must manifest itself among commercial pilots, especially with so many former military pilots in the senior ranks. It might be too easy a conclusion to draw, but it surely was a factor. Thank you again. Was on the OZ flight to and from SFO last month, now OZ 212, operated by an A350, landed on 28L, I think. Brought a few small boxes of chocolates for the cabin crew - just a little thing, just wanted to show some appreciation

The most important thing is to always check the thrust and height. These pilots should never fly again as they are not able to understand these basics.

[@Pilotme1]

Im so happy that i came across your channel, now im looking every day your videos, really really good explenations. Keep going with your videos.❤🎉 wish you merry christmas and happy new year!

[@justmoritz]

Well told. And I get (for the first time really) why being able to fly a plane fully manually and get a "feel" for the ac is just as important as fully understanding and relying on the automation.

[@hannamiros]

I was just rewatching the past episodes, just saw everglades and helios and the recent emirates. So glad there's a new one. Even though I don't fly, I find your videos really comforting and informative. Also could you do a video on the first commercial around the world flight? I recently read an article about it and found it fascinating. Thanks for your content ❤

[@FlywithMagnar]

Petter, it's not easy to explain the automatic systems in airliners like the 777, but you make it sound easy. Another factor that may have affected the communication between the pilots is the culture often seen in East Asia. Authorities are highly respected, and even when the trainee considered the line instructor to be one of the better to work with, there might have been a barrier.

[@ebaystars]

the "automatic" systems are mainly disparate relying on Mk 1 eyeballs only to scan, and yes indeed cultural problems I know about I live in asia...

[@jwenting]

The automated systems take some time to get used to, yes. And usually they do a pretty good job, but when used incorrectly (like here) they can hide serious problems until it's way too late. I've done quite a bit (as in 2000 hours or so over the years) of flying 777s (and far more in other Boeing and Airbus aircraft) in Microsoft flight simulator and X-Plane and that's what I learned (and that's just counting the quality addons, not the stock models which are much simplified). Sadly my medical history prevents me from ever getting a pilot license, and has prevented me from pursuing my childhood dream of becoming an airline pilot ever since failing my service medical 35 years ago, or I'd quite likely be that senior long haul pilot by now flying a 777 or similar.

[@japsnr]

your explinations of systems are fantastic

[@TheForbinExperiment]

I’ve only recently discovered and subscribed to your channel - but I wanted to commend you on the outstanding content. I’m not a pilot, but have been a lifelong lover of aviation. As they saying goes, it takes an expert to explain complex ideas simply. Amazing work. Thank you.

[@Aldairion]

I have been looking forward to your perspective on this incident. It's fairly fresh in my memory and it's interesting to learn the details again. Also, these animations are getting next-level! Keep up the great work!

[@MentourPilot]

Thank you Rahul!

[@m118lr]

I remember this really well. Was astonished at the carnage BUT also very surprised with how many survived. I MUST SAY, your videos..editing, graphics, etc..the whole enjoyable “experience” is like that of a movie, OR quality documentary. Seriously top-notch stuff! Great work..

[@aireconcorded]

Every tower controller working at SFO for this accident were awarded the Archie League Medal of Safety from NATCA in 2014, thanks to how flawlessly they handled this event. Same year my dad was awarded one. Love how quickly the six degrees of separation work on such an event as this. I love how you told this story! One of my favorites to rewatch!

[@Maris_P]

The visuals and explenations in the vido were great to give me, a person who has no experience or knowledge in this field, a rudementary grasp of what happened leading up to and during the accident. It also did a lot to make the "story-telling" more engaging. This catastrophe is truly horrible and I appreciate that I now at least somewhat understand why and how it happened. I especially liked the final part about what consequences were drawn from the accident to increase safety in the future. I would have liked it if there had been a few more senteces on that topic.

[@michaelzilkowsky2936]

Mayday did a good program about this accident, too. Investigators later discovered that in all of the captain's flight hrs, he had fewer than 100 hrs of hand flying, which ties in perfectly with Captain John Hansen's comments (Captain of Northwest Flight 85) that 'with all the automated cockpits, hand flying is in danger of becoming a lost art.' I thought pilots were up there because of their flying skills, decision making, etc, not for their being able to understand the dozens of different configurations that can change because of a wrong switch throw.

[@fareedmasood]

Hi, your ANALYSES of these flight associated disasters are marvelous, mind blowing and the animations are ultra high quality. Wishing you a more prosperous future with more innovations and more and more sponsors too!

Where to begin? Incredible content and by far, the best aviation channel on KZbin bar none! Thank you!

[@user-xz9hu4rd2v]

I always told my first officers that when high and fast, the landing gear was the ‘great equalizer’ and to not be afraid to lower it earlier than normal because that would improve the rate of descent.

[@MikeSierra8282]

Sir, your content, especially an accident investigation is the top-notch. Thank you for your work and time.

[@pateli2008]

Petter is an extraordinary pilot and teacher at the same time. I'm amazed at his ability to explain complex subjects in simple words. I'm amazed at his ability to always go one step forward to respond the questions I'm wondering about in his stories.

[@JB-9296]

Sad for the loss of 3 lives. But I'm amazed how incredibly strong B777 is. One of my favourites along with B747 and A380. Excellent work Petter and Mentour team.👍🏻

Gosh you absolutely terrify me yet I cannot stop watching!! Brilliant video….again and again. Bob England

[@user-gm3gu2re7s]

I was on this exact flight and route less than a week before the accident, and I remember feeling that the Asiana planes approach was much slower than usual, and remember commenting about it with a friend while we were landing. I suspect this wasn’t the first time this form of unusual landing procedure was conducted on the Seoul to San Francisco route, I guess it may have even been the same pilot(s)

[@Odo-so8pj]

Drastic training faliure. System was overly complex. 4 pilots fluffed it.

[@eyyydoddska]

Been a fan of you, Mentour Pilot, since around 2019. Whenever I have almost nothing to do I binge watch your series on airline incidents/accidents. I learn a lot about basic/moderate aircraft/aviation technicalities, although I seem to have no interest being a pilot in the future. 😅 You should do a video about the recent incident involving Korean Air Flight 631-the Airbus 330 that overshot the runway in Mactan Cebu International Airport-I’m from there, by the way 😁 but of course, let’s wait for the final report after investigations have been done.

[@Fazillah]

I’d love to see you and @74gear do a collab on the simulator where you make up crazy scenarios or take scenarios from real life crashes and work together to land the plane safely. That would be dope AF.

[@Dirk-van-den-Berg]

Petter, in the beginning you make a remark about the flightcrew, that the pilot flying in training didn't remark about his insecurity, although he liked the pilot monitoring. Several years ago, a Dutch footballcoach became very famous in South Korea with the national team. One of his stories included the experience he had with junior and senior players. There was no criticizing of the senior colleagues, even though they still made mistakes. So, pilot flying was not ready telling of his insecurity because - probably - this seniority-thing.

[@MentourPilot]

That’s a very possible reason, yes.

[@topethermohenes7658]

Power difference is a bane to Korean aviation, having mandatory military training plays a big role in this I guess

[@Wolfeson28]

Perhaps still a lingering case of the same cultural hesitance to question authority figures that played such a huge role in Korean Air Cargo 8509.

[@seriouscat2231]

@Jk, the difference is that in the KLM case it was more attributable to the individual. In Korea it is a social norm.

[@janedoe9940]

That's pretty spectacular set of misundestandings and errors. But it's also amazing that despite all that happened to the plane, most of the passangers survived. Of course, that's not gonna make the famillies of the victims any happier, but at least a lot of other famillies were blessed to have ther loved ones alive. Great video, Peter!
