[@JohnStedman-d4s]

@@A220-enjoyer Petter has recently revealed that he left the employ of Ryanair a year ago and is now a full-time KZbinr and online trainer. This was a bizarre and highly questionable choice since it will inevitably mean that he is no longer really "speaking from within the aviation industry" and is becoming unable to establish fully objective and credible responses to current developments in that sector. A shame, because Mentour Pilot was formerly taken quite seriously as a barometer of the strengths and weaknesses of Airline Operations, and is now losing much of that status. Unfortunately, much of the "aviation internet" is now biased towards entertainment, juvenile approaches and hyperbole, and many knowledgeable people are cancelling their Subscriptions to such Channels. My Firm is now spending very little time perusing such Content, and will soon be withdrawing entirely from KZbin and other so-called "social media", in search of more substantial and worthwhile content.

The refueling of the aircraft was not the cause of the fatal accident, but the tower actually allowed two giant aircraft to move on the same runway at the same time in the thick fog, invisible to all three parties, creating room for the crew to make mistakes!

You have made an excellent documentary about the accident on Tenerife. Thank you for your expertise. I am a survivor of this accident. I am 1 of 75 initial survivors and was 1 of 14 walking survivors who were treated at Candelario Hospital and released. In addition, I am 1 of 2 photographers that Sunnday afternoon. The post impact photo that is in this video is one of mine. I give you my permission to use it. (My film was stolen by a Dutch fellow named Hans Hofman who sold copies in western Europe.) I was sitting in 30C, the row in front of the exit door over the wing. Upon impact, part of the ceiling disappeared and I climbed out of the hole above my seat onto the left wing. I found a woman on the wing sliding towards the inboard engine which was on fire. I pulled her further out on the wing, tossed her off the leading edge, jumped off and ran. Once I got away I stopped and looked back. Then I saw KLM and realized they had run ito us. Just then a fireball exploded on the wingtip of Pan Am and the whole plane caught on fire. I ran further away then stopped and took 5 photos of the plane to document what I was seeing. In 2015 I released a book about my experience and more titled "Never Wait for the Fire Truck" by David Yeager Alexander which is available on Amazon. I also wrote about aircraft interior safety and runway safety. Also, I was interviewed by Jon Ziomek for his book, shown in your video, titled "Collision On Tenerife". Thanks again for your good work.

Dear David, sir, @David_Alexander you are evidently one of history's heros, as well as a resource of primary source history. It was interesting to me when also just now reading about how your fearlessness in flying again, immediately, was not deemed consistent with PTSD - while, as a prior PTSD sufferer myself, this is now known to be one of the early symptoms of it. Could the Jeff Bridges movie Fearless have been influenced by your shared revelations of the delay in your apparent symptoms in that era? By the way, were there also further aircraft behind yours in the queue behind their refuelling? Either way I guess no 747 could in those days do a standing 180 degree turn without a tow-truck: it makes no sense to me that ATC insisted on their idea of a taxiing route! So ridiculous to allow two planes on the runway, even for a second! But, did you ever hear from the woman you saved? ✈

I was a flight attendant for Pan AM at that time . That night I flew to Brazil( Rio de Janeiro) two of my friends were working that flight and both of them didn't survive. I learned of the tragedy late in the afternoon while I checked with the hotel lobby of any changes to my schedule. The clerk informed me of the tragedy. It was a sad time for all of us at Pan AM. I still think about my friends. Rip Carol Thomas and Miguel Torrech my dear friends. I can't believe that I am still around after all these years. I quit Pan am in 1982 and went back to the university for a master degree and became and educator. It was a wonderful time my ten years with Pan AM,. I saw the world and became a better person .

Many years ago when I was a kid… I believe it was a 737 we were in.. we were about to land in Switzerland and just before the landing gear touched the runway the pilot violently pulled up. So hard it physically hurt and harder than you’d ever guess a commercial jet could maneuver. A bunch of people screamed. It was because someone made a mistake and another plane started crossing the runway in front of us. Shout out to that pilot 🤞

Such an unfortunate incident, weather was poor, fog, rain, temps dropping. A very slow trek on the runway, could not see one another, the tower could not where any planes were. Unfortunate they did not have ground radar, if so, they could now exactly where they were. No centerline lighting, inoperatalbe.

As an engineer, I understand how design evolves over time and you learn from your design being in use. You can never predict all scenarios, but I’m a bit taken aback by how so many accidents have made the airline industry evolve to be safer. Some of the changes should have been implemented from the start like clear taxiway markings. Such a basic item that might have helped avoid this collision. There will always be the human factor, but I just don’t understand how some basic design principles aren’t implemented until there is an accident.

[@Mattipedersen]

@@daCubanaqt I actually just commented on several recent near misses, that could have ended in a similar fashion, which could easily be resolved with the implementation of a GPS System at all Airports, that would allow all pilots to see where other Airplanes are in the Airport, in relation to them, etc. This seems obvious to me, but as we all know, more often than not, changes aren't made until there is another accident and more loss of life.

Your ability to convey the significant points of an accident concisely and accurately is remarkable. Congratulations and thank you.

[@bsadewitz]

I once was on a commuter train during a prolonged delay, and happened to be seated adjacent to where one of the conductors was standing. I struck up a conversation with him, and eventually asked why we'd been sitting there for so long. This was the busiest rail corridor in the US, and such delays are rare. He told me that someone had deliberately walked out onto the track in front of another train, killing himself. I wasn't expecting that, but what really stuck with me was this: He said that he knew another engineer who had been involved in a similar incident. Someone had walked out onto the track well ahead of his train. He applied the emergency brake, but there was nowhere near enough distance to stop; commuter trains on this line go up to at least 79mph. The conductor told me that the experience of sitting there, watching over many seconds, powerless to do anything, as his train plowed right into this person absolutely wrecked this guy's life. He fell into a severe depression, and there was no way he'd ever drive a train again. Now, thinking of this disaster, I can't begin to imagine how the surviving crew felt.

To think that it could have been avoided by the KLM captain simply asking on the frequency, "PanAm, are you clear of the runway?" I know it's not SOP for aircraft to talk directly to each other, but under these conditions, given the poor visibility, the confusion, and the language problems with the controller, it seems like a perfectly reasonable thing to do.

Yeah, the lack of simple communications seem like part of the problem. I'm sure that if you eliminated the controller, the Pan Am crew could have gotten through to the KLM captain what his own crew kept trying but failing to communicate, that they were still on the runway. My first question on hearing of accidents like this used to be whether the aircraft involved were on separate frequencies or not. Can't believe they are on the same ones but just don't hear the obvious.

[@mrkipling2201]

It seems like the KLM captain, Van Zanten, thought he was above doing things like that. The impression I get is of a man who was full of his own self importance and king of his domain. That's why his first officer and flight engineer didn't say anything about what he was doing or question his actions. I'm pretty sure that they knew he was not following correct procedures and was in the wrong but didn't say that. If only they did. If only they had tried to overrule Van Zanten and took over the flight controls. Yes they might have been fired, but at least they would have still been alive to get another job. 583 people wouldn't have unnecessarily perished either. The fact that this disaster was so avoidable and unnecessary, and was due in a big part to someone's huge ego, is even worse.

Very sad and unnerving. A surviving Flight Attendant spoke to the professional investigator as to why many of the passengers remained seated in the American 747.

Pan Am was for people going on a cruise around the Canary Islands (and most of them were older people) and the KLM was chartered by a tourism company (and I think the lone survivor worked for it) and had mostly younger passengers including children. I flew a charter flight once with Iberia and to a passenger it doesn't seem much different but I don't know administratively how they are run by airlines. At that point van Zanten was spending most of his time doing simulator training and I think his flying time per month was less than 20 hours according to one account. I tended to be skeptical that they were looking for him (though I can understand that it's very possible that they would select him) but who knows? I think the accident shocked a lot of people with both airlines. I think the most important thing that came out of it was the issue of cockpit resource management and how to address any shortcomings and to improve it. I think it's had a great impact. JetBlue's landing gear situation and United Airlines 232 (which is the case most often cited) among others.

Actually, KLM has always strongly disputed the findings of the investigative reports (both the Spanish authorities and The Airline Pilots Association (ALPA), which place the immediate cause of the collision on Van Zanten's actions in starting his take off roll without clearance.

[@radfem2010]

@@sct913 They sure did and continued to run ads claiming they never had a fatal accident even after Tenarife, their argument being it was a charter flight and thus didn't count. But it's not uncommon for disputes to happen in investigations and there's the option of a minority report like happened in PSA 182 (1978), SilkAir 185 (1997), Egypt Air 990 (1999) and some others. The NTSB also took the nearly unprecedented step of releasing/leaking black box information on China Eastern 5735 (2022) even though it wasn't the leading agency involved in that investigation. Disputing investigations when there's more than one agency involved (which can happen according to the agreement airlines work on when determining jurisdiction for the investigation and all parties that can participate in that) happen. Particularly in cases like SilkAir, Egypt Air and to an extent, Malaysian Air. I assume the NTSB possibly released that information in anticipation of a similar issue with China Eastern but that's just speculation. SilkAir had the advantage of actually having a lawsuit by the families of passengers filed against Boeing (in relation to the documented (and fatal in two out of three documented cases) servovalve issues with its 737-200/300 series. And Boeing received a trial verdict against it siding with the families. Albeit from a trial where not all evidence was allowed. From what I've researched of Tenarife (which took the life of 583 including the mother of a family friend) is that there were a chain of events that took place that led to that crash. For example, take out the terrorist threat/bombing at Las Palmas Airport from the equation and it probably would have never happened yet you can't write in a report that the terrorists caused it by initating the chain of events because that's not accurate. Sp anish ATF and both airliners, were major factors as was the weather and issues with Tenarife's ability to handle a larger load of planes including two 747s. What is true is that the KLM flight was a charter flight (as PAN AM flight was) not regular service. What is true is that Capt. Van Zanten was the Captain on that flight. What is also true is that at least one of the three member crew, the first officer was certified by him. What was true is that he was considered to be KLM's most senior and venerated pilot, and was literally the face of KLM (on billboards). What appears to be true is that he was the one that was sought out to be assigned to the investigation team. Some doubt exists because there's an assumption that they would not seek him out b/c they would already know he was dead but it's possibly true. Charter flight. Lots of confusion after a plane crash with fatalities especially when post crash fire is involved. Van Zanten took off without clearance. Even if there'd been a sound distortion impacting communications that doesn't equal clearance. The Pan Am crew seemed disoriented from the fog that blew in off the mountain which can happen quickly in Tenarife. Was it even appropriate for the ATF to authorize taxis and takeoffs on an active runway in conditions of such low visibility? Was ATF distracted by a televised soccer game (and wouldn't the sterile cockpit rules apply to a sterile ATF room(s))? How much active flying time (outside a simulator) did Van Zanten have in an average month and in the months preceding the crash? What is Simulator Adaption Syndrome and did it play a role? It seems to be clear that at least with KLM, the penalties towards going past authorized flying/duty hours might have factored into Van Zanten and his crew's state of mind. They are human beings not machines. One major development that came out of the Tenarife disaster was Crew Resource Management, which imo is one of the most important improvements made. United 232, US Airways 1549, Southwest 1380 and others have helped show how that can work during a crisis. And the thousands every day we don't learn about.

At the time of this accident I was a Pan Am flight attendant. I remember the captain and first officer well. A couple of flight attendants I knew survived. This disaster rocked us as crew members to the core. Watching this video 45 years later, still brings me to tears. Like all aircraft disasters, it’s never just one event but a confluence of events any one of which might have changed the outcome. But the overriding cause I see, was the impatience of the KLM captain. I learned when flying in the ‘70’s, one needed to have patience above all and be flexible. One never knew what events would conspire to disrupt one’s intended plans. I’m still gobsmacked that captain after his long career was not prepared to be more patient. It would have saved his own life and almost 600 other souls. RIP my friends. Well done video. Thank you.

I was in the third airplane, an Iberia airplane that was following the KLM from Gran Canaria to Tenerife because of the bomb scare. When our pilot was landing in Tenerife he immediately, after touching ground, went up back into the sky. So many years later I still remember being strapped to my seat and feeling the plane go up and after several moments the pilot said that we were going back to Las Palmas. We landed in Las Palmas, the plane stopped at the old airport and people were running towards the plane, including my parents (I was 14 at the time and travelling alone). My parents didn’t mention the accident but when they started to receive condolences letters from friends thinking that I was in the KLM plane as I am Dutch, they explained about the bomb scare in the airport of Las Palmas, the crash and the fact that people waiting for their loved ones didn’t know which plane had crashed, KLM or Iberia.

How quickly does the post in Las Palmas work for people to have heard of the tragedy, figure that you might be on the flight, wrote a letter, send it and have it delivered in the 30 minutes it takes for the flight from Tenerife to Las Palmas?

[@bwacuff169]

I'm trying to figure out what you're saying: so, your plane was one of the last of the redirected planes to arrive at Tenerife. And your plane was supposed to land right after the KLM had taken off, then get at the end of the line of the planes that were waiting to take off at that point - all of which would have landed at Las Palmas before your flight (had there been no bombing). Basically the ATC at Las Palmas decided to not let your plane "cut in line" just because you were in the air when Los Palmas ATC had resumed operations. Your pilot touched down - saw the wreckage/fire - then immediately executed a go around that ended up with you landing at Las Palmas.....having "cut in line" anyway, because of the crash. I'm not calling you a liar or anything like that: I'm just slightly autistic and my brain has to figure out all the mechanics of something like your story or it drives me nuts. I'm guessing English is a second language for you and you're having a little problem writing what happened to you in a way a natural speaker of the language would.

Seeing these depictions of the events, leaves me frustrated. Let me preface by saying I have two former ATC's in my family. I am quite an aviation buff. And so on. Once the aspects of this incident leads me to ask, why with such low visibility was not the airport not placed in a stop all traffic status? Failing that, the CVR transcripts as described indicate to me an abject failure to adhere to standards and practices of communication between aircraft crew and Controllers. Also, the use of non standard language seems to be a major issue. IMO this accident was absolutely avoidable if those who were in charge of both the tower and the KLM flight had just adhered to procedures.

Twenty or so years ago I was a passenger on a flight out of Atlanta bound for Denver.

The captain repeated an old pilot's aphorism, "It's better to be on the ground wishing your were in the air, than in the air wishing you were on the ground." After a delay of about forty-five minutes, which included some hard rain and wind strong enough to rock the stationary plane, we took off.

[@witchy90210]

I dont think there has to be completely authoritarian for the scenario to happen, as its not written rules that lead to that environment. I dont know if its bias from how its normally presented, but I think that Van Zanten's high regard and others not questioning his seniority, and the rules KLM had in place and him wanting to follow them are a large part of the fault. If that one rule hadnt been in his mind so strongly, and the penalty being so strict none of this would have likely happened.

[@StevePemberton2]

@@witchy90210 The rules are designed to prevent pilots from being overworked and flying without enough rest. Many accidents in the past were caused by pilots being fatigued, or at least that played a major role. In this case the captain took off without receiving takeoff clearance, which is something that is extremely dangerous and has a high probability of causing an accident, as it did in this case. You seem to be suggesting that they should eliminate the work hours rule and go back to having tired and overworked pilots just because of what this one pilot did.

[@CrownedWithLaurels]

@@StevePemberton2 The other commenter didn't suggest that at all. That's a real "so you hate waffles?" response. There's a difference between having limits on flight time, which is obviously necessary, and exposing pilots to personal criminal liability for breaching the flight time restrictions, which is a terrible, counter-productive idea.

[@StevePemberton2]

​@@CrownedWithLaurels You are correct they did not literally say that there should be no rules on work hours. In fact I am quite sure that if asked they would say that they are not against such rules. However rules without any type of enforcement or disincentive are more like guidelines, not laws. And yes I realize that the commenter is likely also not against having some type of disincentive or penalty, in fact they mentioned their opinion that the problem was “the penalty being so strict”. However that was an interesting choice of words, "strict", instead of severe which is what they likely meant. However either word gets to the heart of my point, because severity of punishment and strictness are very much related. It has to do with how important it is for the rule to be followed, i.e what are the possible consequences of someone ignoring the rule. In the case of airline travel it doesn't take much effort to imagine what those consequences might be. The suggestion of the commenter was that the work hours rule did not need to be so strictly enforced, which implies that it’s not quite so serious of an issue that someone needs to go to jail for it. I understand that viewpoint, and there is a valid argument whether criminal penalties are necessary, could other penalties be used such as suspension or demotion. But the other viewpoint on this is that hundreds of lives are depending on the fitness of the flight crew, so to what extent does the strictness of the rule need to be dialed back? And anyway it is extremely unlikely that the captain was worried about going to jail. For one simple reason, all the captain had to do was simply follow the directive given by the dispatcher and not take off from Las Palmas later then they were allowed to, however inconvenient that might be to him and his crew and passengers. Just like you likely don't worry about getting arrested for shoplifting every time you go to a store, because you know that all you have to do to avoid this is not stick something in your pocket or purse and walk out of the store without paying for it. Enforcement at a criminal level would likely occur only if a captain purposed refused to obey a time limit given to them, for example if the captain said to his flight crew, “That’s a stupid rule, I feel fine, we’re going now I don’t care what the rules say”. The pressure that the KLM captain felt, yes because of the rule, was the possibility of his plane getting stuck in Las Palmas overnight. But that is a normal situation for pilots to be in for many types of reasons. For example what if the time constraint was the Las Palmas airport curfew on takeoffs, i.e. a scenario where if they didn't get to Las Palmas soon enough there was a risk of not being able to take off prior to the nightly curfew. In that situation the captain would have felt the exact same pressure, and yet no one would be blaming the Tenerife accident on the inflexibility of the Las Palmas airport. Even if most curfews are solely for neighborhood noise reasons, not safety. The sensationalized idea of jail time for the captain is a red herring in my opinion that distracts from the more important issues in the Tenerife accident. I was replying to the specific commenter’s statement, _“If that one rule hadn’t been in his mind so strongly, and the penalty being so strict none of this would have likely happened.”_ This puts the majority of the blame for the accident on the rule, as if the captain should have been allowed to think that it would be okay to sometimes continue flying after exceeding the work hours limit, as long as they had a good reason for it. In fact this opinion has been stated by many other commentators on this topic. Even though the commenter here did not use those exact words, it is pretty clearly implied by the fact that they put the majority of the blame for the accident on the fact that the captain knew that he was not allowed to violate an important safety law. I don't buy that argument, and that is the opinion that I was expressing.

[ So DON'T MAKE ANY CRITICAL MOVE until you have the whole picture! ] If such technology had been available in the mid-'70's it might not have prevented the Tenerife disaster. But if not, it looks like the blame would've been fully on van Zanten's shoulders, plus on his copilot & flight engineer for not wrestling him out of his seat and going to thrust reversers, spoilers + wheel brakes.

There is a documentary account of this accident told in part by the surviving Pan Am crew and sole survivor from the KLM passenger list (who got off the aircraft to stay with her boyfriend) among others directly related to the accident or investigation. The Pan Am captain (or first officer? Anyone?) was extraordinary. A truly wonderful man. Essential watch. It may have been an AirCrash Investigation special or 'the other one''? (Same anyone?). Very possibly the finest work of its type. If you watch that documentary you are left with no doubt who was responsible for the accident. Unlike Mentour Pilot who gives the Dutch Captain an easy time (and a boy scouts pilot badge), here he is portrayed for what I believe he was. A narcissist and accident waiting to happen.

I told my wife and our friends I did not want to take the flight and that I was feeling very weird about it, they were taken aback saying we could not possibly miss the flight. I insisted, it even got embarrassing! As it happens a short while later our flight was actually cancelled due to low visibility and bad weather, I was very relieved and calmed down. We took a flight later around dawn, as the weather temporarily improved. (likely the last flight before the incident) The same day a few hours later this terrible accident happened.

Petter said it nicely once "Pilots who believe they are gods gift to aviation have no place on a modern flight deck." And it often is old experienced senior captains. So they grew up before CRM and don't see it as that essential than a young pilot who has never known anything different. It's why part of CRM is not just how to behave yourself but also how to deal with someone not displaying good CRM practices, for instance young FOs are strongly encouraged to speak up and even intervene if they feel it's needed for the safety of the aircraft. Humans are flawed and many procedures are designed to avoid the flaws of Savannah apes controlling 300 t steel birds at 300 knots. Checklists, lots of warning lights and indications like configuration alarm, if you drop the flaps to 20 or more without the gear down or engines on idle. But arrogance usually can't be easily corrected like someone being bad at stabilised approaches or handling upsets. These people don't belong in jetliners and most have been weeded out or have retired (or ended in fiery crashes). But a few dinosaurs are still left and especially in cultures where strong respect of elders and superiors is engrained these things still happen. Especially 20-30 years ago it happened a lot in some Asian airlines, typically senior experienced captain makes a mistake and the FO doesn't dare speak up because the captain had already yelled at them over some tiny mistake or behaved arrogantly... One crash you could tell the FO knew the Captain was crashing it but beyond one or two times making a suggestion (that would have saved everyone) they give up and await death. You gotta remember the people behind you and that they might not be ready to die rather than risking being yelled at again or fired. Which used happen. Junior pilot pisses of senior captain in management position fired (who often fly rarely and make more mistakes, they have to do extra training today because of that, while a junior pilot fresh out of training might actually be flying a lot better despite fewer hours).

This crash interested me ever since it happened. I was 17 years old back in 1977 and remember the photos on the front of Time Magazine. I had seen many documentaries on this crash and I can say without a doubt that this was perhaps the best presentation. The graphics of the crash, seeing what each pilot saw just before the impact was quite chilling and eerie, because it actually happened. This presentation was very detailed in explaining the fog as actually being clouds among other things that you mentioned that was missing from the other documentaries. Very accurate and educational presentation. I will be looking at other documentaries from you. Thank you.

The lengths the aviation industry go to take lessons after a disaster is absolutely incredible, piecing it all together. It's interesting that humans can hear the same message differently - add in the differences in language, it shows us how successful communication is a challenge and yet crucial in this field. IMO, the KLM pilot heard what he wanted to hear a few times. I also find it interesting that the new out of hours law, intended to make it safer, had the opposite effect and added stress. Had they not been in such a hurry they may have lived. One night away from his family turned into being for good. It's also interesting that all of these aviation disasters are usually down to human error, not always but mostly.

On one hand it's truly and morbidly fascinating to see how causal chains run through, leading from several events to the maximum outcome, where just one interruption in the chain, could stop that. On the other hand, of course, it's not just frustrating, but also truly bitter and sad.

I saw another documentary about this which said that after the passengers had reboarded KLM a head count showed there were four people missing and that, it turned out two children had been separated from their parents, it said that the captain of the KLM was quite abrupt and rude to some of the flight crew telling them they’d better find them, the children and their parents were eventually located and reboarded the aircraft ……… sadly yet another turn of events that led to such awful consequences that day 😢

[@johnstedman4075]

As anyone who has worked in commercial aviation will know, the unruliness, disorganised behaviour and unreliability of passengers take many forms, and it is not at all unusual for stress-provoking situations to escalate from minor beginnings. This is why many pilots choose to work for freight haulers, since cardboard boxes tend to behave themselves. The KLM flight which was delayed at Los Rodeos carried 'package holidaymakers' from the Netherlands, and many of these people would have been likely to have had little knowledge of aviation, may have been experiencing 'fear of flying' as a typical trait of the uninformed, and in 1977 were still wary of the concept of rapid international travel. The PIC of their 747 may have had seniority and experience on his side, but he had spent the previous twelve weeks training junior aviators on a simulator, which was a different proposition altogether in the 1970s. Whatever the case, Jacob Veldhuyzen van Zanten had clear responsibilities in all aspects of his duties, and these included being able to deal safely with all the implications of unforeseeable delays, errant passengers, marginal visibility, language differences with ATC services, crowded airports, having to cope with the idiosyncrasies of a second-string facility such as Los Rodeos, distant activities of militant criminals, possible exigent circumstances and numerous other occurrences. What is not understood by most non-pilots is that all of these vicissitudes are entirely normal in the day-to-day lives of Cockpit Crew and Cabin Crew, and solving such problems is what these people are trained for and paid to do on a routine basis. Except for Mr van Zanten, all others discharged their responsibilities to a reasonable standard on Tenerife that day, and 583 people would have lived beyond 27th March 1977 if one Dutch pilot, for reasons that even today essentially remain unexplained, had not chosen to execute a takeoff when he did not have permission to do so, and quite possibly took an action which amounted to Multiple Gross Negligence Manslaughter in Legal Terms.

[@StevePemberton2]

What is not mentioned in articles or documentaries about this is that the 747's were not parked near the terminal they were parked in a different part of the airport located about a half a mile (900 m) from the terminal. Passengers would have needed to be bussed between the plane and the terminal. Presumably this bus would have been provided by the airport. This completely changes the picture of the logistics of the situation from what one might imagine from the descriptions. One might imagine for example that most the KLM passengers went to the terminal during the delay, and that they simply stepped off the airplane and walked a couple hundred feet to the terminal. But the logistics would have been much more time consuming than this. If we assume that there was only one bus it would have had to make several back and forth trips between the airplane and the terminal, not to mention the loading and unloading time for each trip. And then repeating this for the return trip to the airplane. With 235 passengers on board this would be a lengthy operation even if only half of the KLM passengers went to the terminal. Also since this was not an airport serviced by KLM there would be no KLM staff inside the terminal. Perhaps one or more of the KLM flight attendants rode the bus to the terminal with the passengers and then remained in the terminal with the passengers, and somehow remained in communication with the aircraft for instructions. Or else they sent the passengers to the terminal on their own and expected the airport staff to announce to passengers when they should return to the plane, which is also possible. With this in mind, when the documentary that you watched states "the captain of the KLM was quite abrupt and rude to some of the flight crew telling them they’d better find them". Who is he talking to, flight attendants on the airplane? Is he telling them to get on the bus and ride a half a mile to the terminal to go look for the missing passengers? Something about this picture is incomplete, there are a lot of missing details here.

I was told that it seemed that at the last moment, the KLM tipped it's right wing up in an attempt to miss the Pan-Am. Captain Grubbs said that if it wasn't for that last action, the KLM would most likely have gone right through the flight deck. I was told this and other details by a very good friend of mine - Victor Grubbs son. So, in trying to get out, Victor fell through a hole in the floor into the first class lounge which was on fire.He managed to get out though he was badly burnt, spent a few months in hospital but made a full recovery thank goodness. There was more that was remembered after the event, but I don't recall everything that was said now. There is an unrelated fact, another Pan-Am pilot who was very good friends with Victor used to drop by the house all the time. He wrote space stories. You may have heard of him, Gene Roddenbury.

Such a sad state of affairs for all involved in the disaster.

[@radfem2010]

@@alekhidell9373 Yeah he was the most experienced. Which I think both helped and hurt. From what I read in different sources, he spent most of his time training people in the simulator and not a lot of actual flight time the last few years before the crash. The simulator is set up to give them the circumstances they need for the training. It's a useful tool but it's not real world where things like ATC exist. It seemed like for a variet of reasons (time pressures (shown in part by his decision to refuel at Tenarife instead of Las Palmas), weather pressures, pressures he faced as the face of KLM, awaiting family, etc) His first officer had been certified by him and had less than 100 hours experience on a B747 and challenged him once according to the CVR and then was quiet after that. The FE had around 550 hours flight experience on a B747 as a FE and more flight hours overall than the FO who turned down a captain stint on a DC-8/9 to be FO on a 747. FE was the last person to challenge his Captain on clearance. From a psychological perspective, there are things in this kind of setup that make me ask questions about the CRM of this crew. Which is what ultimately doomed both planes. You're dealing with human beings. Trained and experienced ones but at the end of the day, with strengths and frailities that can factor into their actions. I think with pilots they to the very end at times believe that they can save the plane or at least not to give up. Alaskan Airlines 261 w/ the failed jackscrew was an example where they kept trying until the end and working together. Albeit arranging with ATC to make sure they "troubleshot" the airplane over the ocean instead of land where there were residences and businesses with people inside to avoid more casualties if the plane crashed.

[@eucliduschaumeau8813]

The captain said he could see all the passengers in the fuselage, most of whom were alive and screaming, right after the top was sheared off, but once the fire started, he said it went totally quiet because the oxygen consumed by the fire made them all incapacitated.
