[@midiplaybox3453]

I am shocked. I think pilot training is completely wrong. I think we're going to see a lot more plane crashes until something changes. I guess the basic role of the person who sits at the controls of the plane and calls himself a pilot is to maintain the aircraft within safe flight parameters. During flight 100% of the time the pilot needs to keep an eye on the artificial horizon and speed, everything else he needs to do is a secondary task.

Yeah the cpt was already complacent and lost his situational awareness. If he had taken 2 seconds to scan his instruments (since they were IFR at the time), he would have noticed the discrepancy between the altitude indicator and the yoke.

[@salernolake]

The chairman of Canada's nuclear industry regulatory agency used to joke that he wished that the reactor operator chair could be equipped with automatic clamps. These clamps would automatically lock down the operator's arms for 5 seconds whenever a high level alarm came in. This would force the operator to first study the instrument panel and gain situational awareness, before releasing him to take action. He was joking when he said it, but he was also highlighting the risk of an operator taking action before they've read their instruments and formed a clear picture of the problem, and the required corrective action.

That advice has saved my life more than once. For professional aviators, I imagine that making sure to bypass certain instincts, looking at the instrument panel, and avoiding confirmation bias are probably some of the important life-saving habits.

@@ycoyle2803 , I also find myself thinking in terms of situation awareness. I don't drive a car, but have had a few narrow squeaks because of careless or dangerous drivers - very narrow squeaks when I was off in my own world instead of paying attention to my surroundings. Turns out that listening to music while walking down the road is way too distracting.

[@mikoto7693]

@@MentourPilot Its definitely working, I’ve taken similar lessons from your videos myself. There are some curious similarities between our jobs in terms of importance of following safety SOPs even if it’s a little little slower or annoying than cutting those tiny corners. No doubt you’ll understand why when I tell you I’m an ACS agent cross trained in most of the ramp duties. (I’m not entirely compatible with spending time doing nothing waiting for another aircraft to clean and provide bowser service so I voluntarily undertook most of the ramp training so I can go out and assist them. If I’m working the shift passes faster.) Similarly the lessons in situational awareness transfer into my job and supplement the training already provided by my employer. You might be pleased to know that teaching me about how the mind works when startled and surprised have actually had practical applications during the nine months or so that I’ve worked on the apron, particularly right after a very near miss when the driver of our van somehow missed the incoming Ryanair 737 following the yellow line to taxi to the assigned aircraft stand. It was already beginning to turn to cross our path when we approached. I was seated behind the driver and we skimmed by so close that I could have reached out the window and patted the 737 on the nose. Once past the 737 I had to be firm in insisting the driver pull over at the nearest safe spot because the startle and surprise would make him far more likely to actually cause an accident if he continued to drive back to base. Besides it was inevitable that Airside Ops would come for him quickly so there really wasn’t any point to carry on driving and the easiest thing to do was just wait for them to arrive. Admittedly I’ve always wondered what went through the pilots minds during this incident. From my rudimentary understanding I doubt that there was anything they could do to stop quick enough. They were taxiing and apparently it can take a few seconds for the engines to spool down if they killed the engines or put them into idle and I have no idea if the parking brake is capable of stopping the aircraft while it’s taxiing. I still don’t know how he missed it, planes like that are not subtle. Similarly it’s helpful to simply be aware that prolonged stress and fatigue can affect the mind while I’m under those conditions out there. Having learned about CRM was the other main takeaway and sometimes I think it might be worth learning more specifics would be useful when our supervisor expects us to do something dumb like attempt to clean a 737 without a GPU yet available in the middle of a night shift. Fortunately that doesn’t happen often and most of the time I enjoy the job despite some of the downsides. Oh and if you ever fly into BRS and I’m around I’ll say hi.

[@rolandregamey3749]

In my opinion Boeing could have done a lot more to prevent this upset to escalate beyond recovery. In-flight thrust asymetry should be treated as something out of the ordinary and result in some kind of alert. Also, the bank angle warning could be improved by adding a call out into which direction to turn. In this case: "Bank angle! Turn right!". This is already the case for the TCAS and GPWS. TCAS adds "Climb!" or "Descend!" depending on the action required to avoid collidig with another airplane. GPWS adds "Pull up! Pull up!" when the airplane gets dangerously close to terrain. By just saying "Bank angle!", the pilot needs to quickly figure out the direction to turn to rectify the upset situation. This is an unecessary step in a critical situation. Could there be a reason why the direction to turn has not been added to the callout? I would love to hear your thoughts on that. Thank you Mentour team for yet another excellent accident presentation. It feels like each new video gets slightly better than the previous ones. Keep up the good work, and RIP all crew and passengers on this tragic flight.

[@LiliumAtratum]

It's not the first accident that happens because an autopilot silently compensates for an unusual situation. The situation gets worse and worse, until a puzzling warning occurs or the autopilot disconnects itself entirely. Do you think some kind of earlier warning could be implemented into the autopilot? Something like "I am still managing what you told me to do, but this is getting increasingly difficult and I will shut down in X seconds". I think this could help this and other similar situations.

[@elkeospert9188]

Good idea! It should even be possible that the autopilot checks different possible reasons causing it making it harder than normal to fly the way he should and it this case also give a "Check for asymetric trust " warning as this is one of the possible reasons and could be detected by comparing the thrust of both engines. Also the "bank angle" warning does not tell on which side the problem was detected which could be added Or in general: In my opinion it it not enough if the computer gives warnings and errors - it should also try to find the reason for that warnings and errors by using data from all of it sensors and determining the most propable reasons and give hints to check and recover. But the biggest mistake in my opinion was that the ground service did not react on the repeating problem with the trust levels. It might be okay to clean the connectors if that fix the problem - but as it is not normal that these connectors have to be cleaned so often it should be clear that the real problem must be somethere else and had to be identified and repaired. It is like if I get a low oil warning in my car. I can try to fix that by refilling some oil and if that solves the problem is is fine - but if I get another low oil warning a couple of weeks later it is not a good idea to just refill some oil again and I also have to find out the reason for this repeating problem....

[@Vanha21]

As the Boing stat to implement things as like MCAS to antique plane first flight was 1967, almost 56 years ago, nothing can go wrong. First thing that make the things harder is control wheel to follow the autopilot as it is obviously clue what it wants to do, but also same time it is not show how things are going relative to horizon other than in the instruments that are behind the control wheel.

[@elkeospert9188]

@@LiliumAtratum But a computer can analyze a lot of data in very short time and is not impacted by stress and in situations where pilots not have time to work through checklists I think given the pilots hints that (most probably) causes the problems and should be checked first would be helpful. And I assume that using all available data a software could determine the correct problem in more cases than pilots (which anyway also have to rely on the data presentend to them) In this case the asymetric trust was "known" by the computer and if could be calculated how much impact it has. If that explains the problems the auto pilot has to keep direction it is very probably also the reason for that problem. Another example for that I mean. If the altimeter of the pilot and the one of the copilot are delivering different values it is difficult for pilots to find out which one they should trust. GPS is not very accurate in the measurement of height - but if GPS says that you are on 11500 feet and the alitmeter of the copilot shows 12000 feet while the altimeter of the captain shows 6000 feet it is a very good reason to indicate that the captains altimeter is most possible wrong. You can have test pilots and engineurs working on such "decision helper" using all data from all sensors on ground without any stress and hurry and then code this into a software which could apply all that "knowledge" in a fraction of a second when it occurs in the air.

It's such a muscle memory thing for two high time pilots that, if it didn't actually happen, would seem totally implausible.

[@jochenheiden]

I am an aircraft mechanic and when we “clean/reset connectors” it’s our way of doing *something* to clear a write up when we can’t duplicate a discrepancy on the ground or don’t feel like digging any deeper. It’s sad but it’s the reality. Pilots, if you ever see this sort of corrective action for a write up, it’s probably not really fixed and will probably come back.

[@tomstravels520]

[@sarowie]

@@tomstravels520 Change hats and think like maintenance. The plane is scheduled to lift of in 2 hours - otherwise rescheduling of the flight guest. You need to do handle some more service items on that plane also take time, but you have other planes that you need to handle - otherwise even more rescheduling. Then you look at the trouble shoot and maintenance guides: Some are painfully detailed and specific and need to be done. Others are simply non existent (or you don't have them at hand, because the error described/reported does not lead to that guide). Note that when you test and disassemble systems you have no direct procedure for, you need to be extra careful. Even flipping a switch the pilots are supposed to check every time can cause an accident. Incorrect reassembly will make the problem much worse instead of helping. So... when moving something is risky, dissembling is risky, testing is risky, ... isn't less risk just to leave it be...? Off course, a mechanic can escalate: When would you label a system inoperative? When would you ground a plane?

@@sarowie that depends how important the system is and how much redundancy is available as backup if it fails again. Exactly what the MEL is for. But if autothrottle keeps failing repeatedly then either disable the autothrottle (doubt anyone wants to fly like that), dedicate a team to concentrate solely on that aircraft or if you’re really unsure then get the people who made it in and have them look at it. We have had aircraft problems before that we couldn’t fully diagnose and had to call the manufacturer to look at it (eventually found the cause and procedure added to manuals). The same goes for TK1951 that kept having faulty RA. Although in that instance the design of the 737 didn’t help and it wasn’t clearly communicated not to use autoland

[@scottburling4857]

As an engineer, I am quite surprised that the auto systems didn't alert to when they are unable to perform their functions. Seems like it would be very useful for the autothrottle system to alert to an unexpected throttle position (say to due to a stuck throttle), regardless of asymmetric thrust. Likewise for the autopilot to alert to it hitting the limit of it's control range. Given human weakness at monitoring stuff, would have been better for an alert that something was wrong to come well before the bank angle alert.

[@LPMusicON]

Yeah it's something that seems to be common factor that some of the messages that the aircraft is providing maybe could be more clear instead of general X issue. It's not like they can't afford more detailed messages that'd still be concise

[@flyingdaytrader]

As a pilot who flies his bonanza, these accidents constantly remind me the importance of checklists and actually verifying the item on the checklist. It's easy to say for instance on take off that, "engines in the green" with a quick glance, but looking back how often have I actually verified that vs just called it out as a memory item. I have made it a focus on my flying lately to get much better at checking items off and not just going through the motions. I'm also doing more flights with a CFI even though I don't need any additional training per the regulations, just so I can practice emergency procedures more. The more comfortable I am hand flying the plane the better I am at addressing emergencies.

[@Dheeraj71192]

A question, how much are the pilots trained to hand fly before they are regular with commercial flights?

[@flyingdaytrader]

@@Dheeraj71192 depends on where they are coming from, US trained pilots do a fair bit of hand flying as they go all the way up through CFI. From there it will transition to more time in simulators with more automation. Most of time after that point will be learning how to deal with automation failures and recovering from them so you will be learning how to manually take over from automation but your training is heavily tilted towards working with automation then not. Also depending on your flight school as you gain certifications, if the school has more advanced technology in the planes you are encouraged to use it. Even when flying regularly pilots often hand fly take off and landings to keep stick and rudder skills up. Generally speaking as a pilot you learn to use automation as a tool in the cockpit but are familiar with how it can fail and how you are to take over. That being said many foreign training programs are very heavily tilted towards automation. Also many of these Asian and other foreign airlines require pilots to use auto land and turn over most of the thinking to automation. While everyone who flies has a level to professionalism to them, I would much rather a US or a European trained airline crew over an Asian crew simply because those crews are much more likely to have a smaller startle effect and can hand fly the planes well. But that's my two bits.

Also not picked up is the controls binding. A long running problem on this plane with all attempts at fixing appearing to be blamed on the electronics. Surely the logs should be audited by maintenance and the real fault found and fixed.

did previous crews never notice it ... or just not report it ? AFTER the United Express aircraft went off the runway at Presque Isle Northern Maine Airport ... then PREVIOUS flights started reporting the ILS problem !

[@fraginz]

Here I quote from the report: "... .The differences in engine parameters during aircraft descent and the right thrust lever late on the take-off roll while the A/T engaged, most likely might have resulted in the thrust levers split. The Quick Access Recorder (QAR) data recorded 7 thrust levers split occurrences between 2020 and 2021. No pilot reported on these occurrences in the AML. Most of the pilots stated that they did not recall the occurrences." "If the FMC CDU INTERACTIVE TEST was performed for thrust lever movement problem during the A/T system engagement will result to FWD LOOP or THROT SPLIT fault messages. The subsequent trouble shooting steps would use procedure contained in the AMM chapter 71-00-49 (Power Plant-- Trouble Shooting (Engine Controls)). Similarly, for pilot report of thrust lever split event, the same troubleshooting step should also be in accordance with the procedure in AMM chapter 71-00-49, which contained maintenance steps to check the friction of the engine control cable. Therefore, the termination of the trouble shooting after the BITE test result of “no faults” and without the pilot report of thrust lever split, resulted in the engineers stopped the trouble shooting steps and not proceed to examine the engine thrust control as required in AMM chapter 71-00-49. This is likely the reason why the defect prolonged."

[@CaraVerde]

Two words in the report shown in the video that caught my attention the most: "Automation complacency". Series of intricate automations that has happened in this case was originally intended to help reducing pilots' workload. Unfortunately, the pilots failed to closely monitor the reasons about why the machines made those series of "decision"/automations ASAP. So then when everything became critical, they reacted ONLY to one part of the series (and sadly, the compensating one). If they somehow reacted to the attitude indicator or the thrust levers instead, maybe this wouldn't happen. It's frightening to have the feeling, that if they fly the plane manually from the start, the accident wouldn't happen. They could recognize those problems ASAP because there are no room for them to be complacent. I'm not saying automations are wrong, of course. But we can see in many situations, the more automated the environments, the more the tendency of people being complacent.

24:03 I'm not a pilot but when you're flying in clouds and hear "Bank Angle" warning, shouldn't you look at the attitude indicator and maybe backup attitude indicator to figure out what to do, instead of looking or feeling the yoke? When you consider what could possibly fail in a modern jet, attitude indicator is maybe the most reliable data input you can have.

[@melondoc]

I think that's one thing I've picked up from a few of these videos - although we like to think that every Captain is going to be a Chuck Yeager who will react with 'ice cool' logic in a surprising situation or upset, most pilots are normal humans - if they're not getting regular training on upsets they can just freeze or brain fart like the rest of us.

[@obitouchiha4739]

Most of the time, the Yolk would tell you the correct angled position of the aircraft, but in this case they were unlucky. The Instruments in general is the most accurate, unless of course the information given is false, which would make the yoke more accurate.

One thing I thought about watching the above video, has there been any discussion that you know of regarding changing the “Bank Angle” audible alert to include the direction? Something like “Bank Angle Left” in this case. We will never know if an alert like that would have triggered this captain to better recognize this event, but it seems to me it might have triggered his hyper focus on the yoke to recognized the incongruence between the yoke position and the alert for the “Bank Angle Left”. Perhaps he might have taken the moment longer to find his artificial horizon? I am a Paramedic by training and I am also very aware of alarm overload and fatigue in some situations. Adding extra detail to the audible alert may not be preferred for other very good reasons. Thanks for your time.

Hah, that’s similar to my experience with the introductory training to working safely on the apron and aircraft stands.

I recognised UPS flight 6 immediately and I still feel sympathy for that poor first officer and what he endured alone for the final minutes of his life. But yeah much of the things I’ve learnt from this channel built the foundation of my understanding of aircraft which I’ve since built on. 😆 You know that the lessons have truly sunk in when he apologised for being technical at the start of this video and the responding thought was “this is technical?” Before the thought scatters while following the narrative.

I love these videos! I'm in mechanical engineering and we come across many troubleshooting experiences similar to the venn diagram you showed, though not with such dramatic consequences. Just the other day we had replaced the transmission in a piece of machinery and the new transmission made grinding noises at every shift. we drained the oil, send a sample for analysis.. asked the manufacturer for oil fill procedures, checked and double checked again and again and still, in every test drive, that grinding noise came back. We put the machine on jackstands and ran some tests in the shop with one mechanic driving the machine with it's wheels off the ground and the other one sitting next to the open hood looking at what was going on in there. It turned out to be the powertrain assembly not being properly lined up on the engine mounts and the cooling fan being too close to the radiator shroud. At every gear change, the motor would jolt slightly and the fan blades were grinding against the shroud. All that time, the logic seemed to be that an issue fixed with the transmission must mean the this problem also came from the transmission!

Oh wow, I had no idea other people also have this problem. My parents love watching Air Crash Investigation and through simply living with them while growing up meant I ended up watching it as well. I grew to strongly dislike the series because of the irrational desire to see the pilots succeed in saving the aircraft and everyone aboard even though I knew it had happened long ago and they didn’t make it. I stopped watching once old enough to be able to watch a different programme in another room and avoided such documentaries for years afterwards. It doesn’t happen very often now as an adult thankfully. The only lingering effect is that I find the terrain warning a bit unsettling because one of the few memories I have from watching when I was a kid regarded the pilots being really confused by different and contradictory warnings being given by the aircraft. It was unfortunate that they didn’t heed the terrain warnings. I don’t remember any of the details because it was decades ago but my guess is that it was a problem with blocked pitot tubes.

@@lxdimension yeah by the time they realized they were at over 100 deg bank, and the thrust levers were still wrong remember. Impossible to recover, we are talking about a few seconds from being somewhat in control to unrecoverable (unless they spotted the levers)

[@xonx209]

If it is usually not necessary to split the thrust, why not add a mechanical linkage to prevent split unless explicitly unlinked to allow split.

[@spogeo45]

Excellent video. I enjoy the technical aspects and you explained this tragedy so well.

[@tipsynailsbymichelle]

Don't know a single thing about aviation or how to fly a plane, I just love your videos, the explanations, illustrations etc just make it so worthwhile watching.

[@wasimkhan-gf5on]

Far far greater technical explanation with proper graphical representation rather than unnecessary dramatic episode Keep it up 👍👍 love from an automation engineer 😉

[@TacticalNudes]

A family member worked on the maintenance facility company at the time the crash happened. The company was in a lot of financial trouble, struggling to find funds/income, and this specific plane actually was serviced in the city that my relative worked in, if i remember correctly. This crash devastated the company basically, which is already a mess. well idk if this significant information but i thought it's worth a share.

[@lhw.iAviation]

Petter, you are one professional pilot who present information in an understandable format and you have an extremely talented production crew. Glad I got to know you!! 🎉

[@MentourPilot]

Thank you so much on behalf of the whole team

[@amanduuuh_7117]

This is just so terrifying to me. All he did was be distracted for like 15 seconds and then turn the wheel and bam. All those lives lost. I'm a bit opposite of many comments. I never had a fear of flying before and flew quite a bit. Now after watching these videos, idk how we don't have more accidents. If just one detail is missed, one step taken incorrectly, it's done for everyone. I have so much more respect for pilots after this. Feel like I want to bring mine a huge gift basket on my next flight 😭

[@livinghypocrite5289]

"If just one detail is missed, one step taken incorrectly, it's done for everyone." But it wasn't just one detail missed. It was the lack of proper maintenance, which ended in two systems failing (the autothrottle system and the CTS-system), that was combined with the pilots not monitoring their systems which led to being surprised and out of surprise reacting the wrong way (partly because of wrong training). I'd argue that this wasn't just one missed detail, but a lot of them on different levels, that had to come together.

[@sleepysera]

@@livinghypocrite5289 I think part of what's so unexpected is also the timeframe of potential recovery being so small. Maybe it's just me, but unlike something like a bus where I obviously expect a crash right away if the driver messes up, I always was under the impression that, with the usual altitude planes travel at, there would be a lot more that could be done if something goes wrong. Hearing about how basically one wrong input at the wrong time is enough to bring a plane down, because there's only seconds between the input and the crash too despite the high altitude, is pretty shocking 😅 In this particular case, of course several factors combined, but ultimately none of them would have mattered if the pilots had just taken a single look at their thrust levers. It amazes me flying is as safe as it is with how little can cause major upsets, just means the average pilot is doing that great.

[@michellegrayson789]

I am a nervous flyer. I'm the sort of person who likes to have control and total understanding. Despite my fear, I've taken several flights in my time. Ultra long haul ones too. My next trip is from New Zealand to the UK via the US next month (with 3kids). I am going with Air New Zealand...if course because of their safety record. Then with Singapore...again, safety. Your videos are addictive! I don't know why, but they are really helping me with my fear. I have learned so much about aviation from you. I find myself spouting off in great and complex detail to anyone who will listen! Can't wait for the next video.

[@bitzanu1]

Extremely well explained. I really enjoy these videos. Keep up the good work! 👍

[@bwuepper439]

It seems that systems that are implemented to make the pilot's job easier actually can make the pilot's job more difficult when those systems fail without the pilots being aware of the failure and it's ramifications.

[@MentourPilot]

Yes, that’s unfortunately always the case.

[@gdehms]

I know things are vastly more complicated than it seems from my couch, but I do feel like a mild amount of _extra_ computer guard rails + human oriented UX could have prevented this issue - if a significant difference in thrust is detected, you could have a chime that says in a human voice "Thrust asymmetry" every so often until confirmed as intentional on the flight computer. Gmail bugs me when I try to send an email that says "attached are photos.." without any attachments... I feel like a plane should be able to do something similar for pilots. I'm sure someone smarter than me thought of this and maybe they found it would be too spurious / annoying for the vast majority of pilots. ¯\_(ツ)_/¯

[@bwuepper439]

@@gdehms I guess I was thinking about other accidents that killed many. For example, the recent Boeing 737 Max accidents could have been avoided if the MCAS had been implemented better. I also think of Lada Air where the thrust reverser had deployed in flight. I wonder if the pilots could have shut down the engine quickly would that have made a difference? There are enough sensors in airliners that a decent program could provide a more intuitive interface to the pilots, not replace their judgement.

[@vasilivh]

@@gdehms there's of course always a balance between too many and too few warnings. If the plane warned the pilots of every single thing, there would be warning chimes ringing in the cockpit all the time. So some of the more obvious faults causing autopilot disconnect, like asymmetric thrust, are left for the pilots to discover since it's right in front of you (thrust levers and engine instruments both immediately reveal the problem). In this case, though, the thrust asymmetry warning wouldn't have worked regardless, since the system that should have detected it wasn't working. And since the pilots didn't react correctly to the bank angle warning due to being startled, it's a bit unclear if another warning on top would have helped. The pilots were already in trouble after losing situational awareness in IFR conditions, they just didn't know it. Perhaps a "look at your instruments" warning every 20 seconds would have been useful here..

[@arun120977]

What a sad, sad story. The best training would have been for the pilots to pay attention to instruments. But the real culprit is the safety culture of the country's board and the airline.

[@thureintun1687]

yes we have a tenancy to ignore the value of human life here in S E Asia Don't know why? 🤷

[@landmanland]

The most difficult part seems to me training your reflexes to always quickly assess THEN react. Not so much applying immediate a (perceived) solution, but following a set of visual and mental steps.

[@sarowie]

true for the last seconds. but... an instrument and/or flight control scan would have shown: Engine levers in disagreeing position. Engine with wildly different performances. With those indications, the correct action would be obvious. Artificial horizon showing a wrong direction: Hold the flight controls/increase input - not the "corrective" action, but at least not making things worse.

[@TheDiner50]

Eh. Hard and hard. Someone new at driving a car and a bird hits the windscreen? Can you expect the driver to not sway and end up crashing into something? But someone supposedly experienced and trained should not flip out and take actions that are deadly or just wrong. Have driven vehicles and had birds hit me right in the face out of no where and only closed my eyes for a split second before recovering my senses. It helps having a windscreen that can take the hit for you. Was driving a 24m long 60 000kg heavy lorry at 80km/h. 3 lane road with cars traveling next to me and nothing to stop me jumping over to the oncoming 3 lanes if the bird startled me. Ones in a position of being trusted to not make rash reactions when flying or maneuvering anything. The bird hitting your vehicle even if in your face is not meant to have you take any reaction not even hit the brakes even. Your expected to be so well aware of your surrounding and have the situation awareness to be able to quickly asses and have everything under control. The person riding with me was half a sleep and wondered what the sound was from. If not for the huge DUNK into the windscreen there was no upset but the drivers eyes blink and then everything was over like nothing happened. Imagen the damage that can be caused from just a bird or a fly hitting someones windscreen. Or bonnet flying open or literately anything. Someone not really experienced or whatever is not really ready for that. I remember the summers of having flies hit my windscreen. I'm awful when it comes to people throwing balls or anything towards me. It is just to dangers to not quickly assess THEN react. Only time it is react and THEN asses is emergency braking or getting out of a drift/loss of traction. There is no time but react. But since I started to become even half decent at driving my FPS shooter and in general sharp reflexes are just totally gone :c. It is really hard pulling a virtual trigger on someone as fast anymore. It takes everything out of me to get out of the mindset of not quickly assessing and just flick shot someone. It is really upsetting having to super focus to get flick shots off. It was not something I struggled with before driving.

[@Vince-wq8xr]

Fascinating, as always !! Looking forward to next, have also an absolutely fantastic day, Peter 🤗

[@rjbishop12]

WOW- this is one of the most convincing cases of confirmation bias that I have seen. Without looking at the throttles and attitude of the aircraft, I dare say it would have been impossible do anything different than the captain did. I am a GA pilot, and this brings to home the very strong argument for TOTAL situational awareness. I try to challenge myself by flying in VatSim events on the flight simulator, and run across many navigation challenges that keep me on my toes with regards to situational awareness. I will continue to respect this aspect of flying and try my best to stay on top of my airplane at all times, regardless of how "easy" it is to fly. THANKS for a great video!

[@periidote9778]

I'm a frequent flyer and have always been a little nervous on planes and even though a lot of these videos are accident/incident videos, they have actually made me feel safer. To learn about all of the different safety features in detail as well as the pilot training and procedures has made me a lot more confident when flying because now I can have a lot more trust and understanding of what really goes on when flying. Thank you!

[@mikoto7693]

If you think knowing how much effort is put into making each flight safe while the planes are parked on the ground being prepared for the next flight, feel free to ask and I’ll answer what I can.

[@skwervin1]

Petter, I just have to say I have been watching your channel for over 2 years now, and I love and appreciate your patience in explaining what is happening in clear, concise terms. You explain thoroughly what is happening to the aircraft, what the pilots are seeing and doing, and on occasions, what the cabin crew and passengers are experiencing as it affects the situation. You give us the facts, visuals, etc, without over dramatic re-enactments that detract from our ability to concentrate and absorb the issue. I hope that flight schools, pilot trainers, and others are using your videos as training tools to show new pilots what can go wrong and how it was dealt with before. You don't just focus on crashes, but also those cases when things have gone severely wrong and the crew has saved the situation, which is just as important a lesson as the ones that fail. One way it could be used training wise is to run the pilot through a simulator of the accident, then watch your video, then back into the simulator to see if they can improve.

I live in Tenerife but have to fly home to the UK quite often. I literally download your videos specifically to watch on the plane and it actually makes me feel safer. That’s because it gives me the confidence that so much thought and analysis goes into the aftermath of these terrible accidents that I can be very confident that statistically, it is basically impossible that the same thing will happen to me. Your video about the Los Rodeos incident (still the deadliest aviation accident in human history and one of the best videos on youtube) which took place here, brought about so much change in the industry that I can comfortably watch it on the plane and feel safe. I iust have to cover the screen so no other passengers catch glimpses of exploding aeroplanes while we’re taking off! Absolute respect to you and the team this content is some of the bet I’ve ever seen online. But please do the Spanish dubbed versions on a separate channel like mr beast does (not that i like his content particularly)but its an incredible idea as he reaches another massive audience and us spanish learners can improve our spanish while we’re enjoying your awesome videos!
