Years ago, I made several videos showing you how to open the different doors of a Boeing 737. And in at least one of these videos, I told you that it is practically IMPOSSIBLE to open a passenger door in flight…and yet, in May this year, we learned that an Asiana Airlines passenger managed to open a door in an Airbus A321, while the aircraft was on approach in South Korea. So, how is this possible? Stay tuned!

Passengers should be thankful for hairdryer for free.
This video was incredibly entertaining and informative. Thanks for helping me to overcome my fear of flying
Should they now over pressurize the cabin for landing so this can't happen again?
@@mballer AFAIK they slightly pressurize the cabin, bringing the cabin altitude slightly below the actual landing altitude.
When I heard this story i thought "I hope Petter covers this"
Thanks for making wishes come true ☺ ♥
When engineers design a foolproof system, the universe conspires to design a better fool.
Wow, well said!!
I have a t-shirt that says that.
Engineers know that given enough time and people they will try everything. So many laymen were concerned, so many pilots covering this up for safety. But the single fact that opening a front door could've resulted in a slide going into the engine, possibly letting any fool to bring down a plane with zero tools. That is not fool proof, that's engineering so fool accepting, or malice accepting, that it should never be publicly accessible. Airliner doors should not be less secure than the child lock on an old honda.
lol
Yes, warning labels perform the same function.
15:00 “A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.” - Douglas Adams
Correct
Sadly so true
cant call them complete fools if they beat "the system".
I would argue that those who designed the system are the fools in this case for thinking they could design a foolproof system.
Had to edit this because people dont read any further. And so: This was a joke......
I said that a few comments down the line already.
Hopefully people will now read it and stop responding. Because to be honest, it makes you look like fools to me to be honest, responding to something which basically should have been clear enough not to be taken serious.
But i guess that is the world we live in these days.
Like people who see a sign that says "DANGER
Do Not Enter" but read it as
"PERFECTLY SAFE
Come On In"
@@bertjesklotepino Yes they can. Foolishness is not the same as being mentally incapable or having less than stellar intelligence. A fool is someone making stupid things, and it is a fact of life that _everyone_ makes stupid things at some point rendering themselves a fool.
Thus, your argument is invalid.
The real story is that the man was seated next to the door and said to the guy next to him, "I watch this great CZcams channel called 'Mentor Pilot' and he explained that it is completely impossible to open these doors in flight...see, no matter how hard I pull...OH MY GOD! HE LIED! HE LIED TO US ALL!"
I can see Rowan Atkinson playing that role 😅
there was a pilot convinced that he could not retract the landing gear while on the ground, there must be some interlock.
His copilot did not believe him. The copilot was right.
🤣🤣
😂😂😂
underrated comment!
Difficult design problem here: to design a door that can ONLY open in an emergency but also will open reliably in EVERY emergency. Add to that that emergencies are by their very nature hard to anticipate and catalogue.
I regard the design a success: nobody was seriously injured.
I suspect the guy succumbed to intrusive thoughts and it’s amazing it hasn’t happened before.
What you are suggesting is a door that is also a qualified psychiatrist.
Yes, I work on fire alarms and can assure you that locking a fire exit from the inside of a commercial building will get you into serious legal trouble if it prevents people from exiting during an emergency.
I think as he mentioned tho, on many types of planes the seats next to the exits are occupied by flight attendants, so there’s not as many chances as there otherwise would be for a regular passenger to attempt to open the exit
This kind of reminds me of the problem with bear proof trash cans. It's hard to design a bear proof trash can because the overlap between the smartest bears and the dumbest humans is way too big.
Yes, I understand that it's impossible to create a door that will work in all situations, and it doesn't make me nervous to fly - like it was pointed out to us, it's super-crazy-rare. I bet you have a better chance of, saying, being in a car accident, and nobody thinks anything of getting into their cars every day.
A perfect system is impossible, I imagine, so I appreciate that they've done the best they can. We expect them to do their best, and they did; we can't expect more.
As for the idea of intrusive thoughts, well, I don't mean to be rude, but, as a person who has Anxiety Disorders, I'd just like to point out that it really would be best to not guess at if he had a mental illness, and, if he did, what it was - so very many mental health issues (if that was the cause) could have caused it, there's zero reason to jump to the conlusion of intrusive thoughts.
Well, actually, now that I re-think that, I suppose there's no harm in pondering weather he suffered from a mental illness. But I do think that we should not guess at which one - intrusive thoughts are possible, but so are hundreds of other things.
Intelligence has limits. Stupidity has none. 😂
Reminds of the incident where an older Chinese woman was observed throwing coins into a jet's engine for 'good-luck'!
Stupidity like not using metric system, you mean, right?
@@Joker44131 stupidity in general, not just metric system
Or it was a mental illness. There's already so much stigma against the mentall ill, don't make it worse by calling a potentially mentally-ill person 'stupid'.
@@Joker44131 No.
This Mentour Episode was a complete breath of fresh air.
Take my like and get the heck out!
Yes it was a blast!
And some fuel fumes
😂
Breathtaking
As a frequent flyer who likes the window seat, it has always been a privilege to be given the responsibility to look after the emergency exit. I actually felt important like part of the team 😂
Now I gotta fight idiots too, on top of my high ranking door position?? 😭
At that point apply to be an official emergency door watcher lol
Yes people it's a joke
HODOR
@@camlo1134are you serious? That's not a real thing.
Yes, it's an joke
When ever I board an aircraft I reassure myself with the knowledge that the flight crew want to live just as much as I do.
The germanwings Alps crash proved that is definitely not the case
@@TheTransporter007 Before reading your reaction, I thought the same!
There are more examples of that "not being the case" :-(
Even without knowing about the crash in Alps, how he would had knowledge? Did he talk to the pilots? All he can have is an assumption and airline track record.
@@pavel9652 Of course, one can't know anything for sure. But, the relatively low incidence of suicide in our society leans heavily that way. Then, consider that most people planning suicide may look to also take with them those they blame for their situation, most do not want to hurt other noninvolved people. Lastly, consider that most commercial airliners have a flight crew of 2 or 3 people, that lessens the chances of one pilot taking control. I am far more worried about incompetence, pilot error, and diversity hires.
@@BryanTorok True, but he said he reassure himself with knowledge, which he doesn't have ;)
A couple of years ago a woman opened an overwing exit door after the plane had landed and arrived at the gate. Apparently she felt that it was too hot inside the plane, so she stepped out onto the wing to cool off while waiting for the line to start moving. A flight attendant convinced her to come back in. She was not prosecuted but she is now on the no-fly list.
What a goof. Petter and Mentour Wife talked about this event once.
I remember that lady... ugh some people.. 🤦♀️
@@sashabenoit1518 Was that not the case where they had been delayed, leading to hundreds of passengers being crammed into a metal box for 2 hours with no AC in >30C weather? Someone else had already fucked up.
Smart gal! That would definitely reduce temrerature inside! I bet shes the one that fucddles iwth the thermostate at office, just to piss off everybody xD
This reminds me of someone pulling the emergency stop button at a train stop as the train was going past. Apparently she wanted to get off closer to her home.
Never underestimate the sheer power of human stupidity.
exactly. smh
Or insanity.
I agree wholeheartedly. I work for an airline and sometimes am completely dumbstruck by people. I regularly have to try to talk rationally to passengers who are hostile. They want a better seat that they didn't pay for or drinks before takeoff or a bag that doesn't fit on board and they look at me like I'm trying to ruin their vacation. I look at them and wonder if there is going to be an in flight emergency. And yes.. I do think about something that happened over 20 years ago.
Or, as my first boss once told me: "you can make things foolproof, what you can't do is make things Bl***dy fool proof"
That's why washing machines and dryers now have a warning about putting children inside
I knew it was because of the low altitude that the door had no trouble opening, but what you said about how the slide could have possibly been sucked into the engines really is chilling... It could have gone so badly, and we're so lucky it didn't. Thanks again for a great video!
Bro. Spoiler
It should be so that the slide won’t work if the engine is running
@@brianmilo7662 Then don't read the comments before you watch the video.
@@Jwellsuhhuh I'm sure there are circumstances in which you would need the slide, even while the engine is running. And who knows what else such a 'fix' would effect. That's the thing - it's not a simple thing, not a simple fix, it's multi-faceted, and there's so many situations and issues to consider.
@@Jwellsuhhuhthere should be an interlock on the emergency doors to keep it locked while the plane is flying. What good would it do to open the emergency door while they are airborne, not like they have parachutes onboard. Im not saying its an easy fix, but an actuator set with a fail open solenoid comes to mind. In cases where the the plane is still in the air and the plane still has electricity, solenoid will be engaged, but once its on the ground and power is cut (or lost), solenoid retracts
In the early 90's we were on a 10 hour flight from Dusseldorf to Orlando. My son, about 3 at the time, was restless, got up from his seat and tried to open the door. The flight attendant saw him, smiled and asked if he wanted to see the pilot instead. He was gone for about a half hour and I had no idea what went on in the cockpit. The flight attendant escorted him back to his seat as he carried airline toys, coloring books and flight pins. Wow, things are different now.
I got one of those wings the first time I flew as a passenger to Rome Italy
A selfish few have ruined it for everyone
Yeah, im 43, and I remember when I was a little kid, I was really into anything mechanical or electronic, and my father took me up to the cockpit, and they showed me around, and I think maybe even let me sit in one of the seats briefly, though I could be confabulating that lol. But I do remember getting some of those toys and stuff. This would have been in the mid-late 80s. I remember being astounded by how many buttons and screens and stuff there were, lol.
A lot changed after 9/11.
I guess the big issue here is any lockout added would need to be insanely overengineered and redundant because the problem of someone opening a door when they shouldn't is far less of an issue than someone needing to open a door and it remaining locked.
I am absolutely shocked that there's no lock on the door. Presumably engineers have known for decades that it is possible to open the doors of the plane at anything below 1000ft but have just kept quiet about that particular extraordinarily dangerous problem. As you say, there would need to be redundancies, but I always assumed there was a button that the pilots switched to unlock the doors or the locking mechanism went on altitude or, as mentioned in the video, engine spooling. All it would take is an emergency button like a fire alarm in the cockpit and then in the cabin away from the door always by a flight attendant.
@David in an emergency where pilots lose control of the electronics in the cabin that's a potential hazard
already fitted on 737NG overwing door.. and it is an headache to test
@@David-ud9ju What happens if the pilot are incapacitated? Or the electronics has failed, or the circuit interrupted.
@@David-ud9ju The risk of needing to open an emergency exit quickly and not being able to because of a failed redundant locking mechanism is higher than the risk of some bozo opening a plug door at low altitude. This popular aircraft model has been in service around the world for 29 years and this has happened exactly one time that we know of with only minor injuries and minor damage to the aircraft. It's pretty rare that somebody is able to even attempt to open a door unnoticed by fellow passengers.
As a private pilot, I know I’ll never need to deal with most of these type situations, however these videos are always very informative and educational regardless. I really do appreciate the time and effort that you put into these.
Thank you! Glad you liked it, that’s why we work as hard as we do.
a bot reworded your comment using AI
Never know when you might want some fresh air... and forget you're the one flying. 🤷♂
@@jeffrey.a.hanson if he forgets he's the one flying, he will likely face MUCH bigger problems.
Did it ever happen that some schizo entered the cockpit?
I agree. The armed doors, easy and quick to open in an emergency, probably saved way more lives, compared to the 3 minutes of discomfort we have seen here one time only in history.
But once people know this is possible, imagine what a terrorist could do with that knowledge.
@@themobseat What could they do? Opening one door at low altitude doesn't affect the aircraft at all, as we've just seen here. They could jump out I guess. No one will be sorry to see them do so.
Security and safety are often at odds with each other. Security measures like locks, fences, barred windows, etc, are safety hazards, and safety measures like emergency doors are security weaknesses. In this case, security would want to make the emergency doors more difficult to open, which would be a disaster for safety. It was an isolated, relatively minor incident, so they'll probably leave things as they are.
Boeing exit doors over the wings automatically lock when the planes wheels are off the ground. The same thing could be used on the A321 doors.
@@dannydaw59 How does that work if the landing gear is ripped off during a crash landing, or when belly landing or ditching, or if the aircraft tumbles and ends up upside down, etc? How do they make sure that the mechanism which detects whether the wheels are on the ground doesn't malfunction? If Boeing implemented it, I'm sure they thought of all that. I'd actually like to know.
@@ironcito1101 Importantly only some of the doors on a Boeing lock that way I think, so if the locks won't open people can still use the other doors.
Sounds like a Free Market vs Controlled Economy debate...
Acute observation and great explanation. My mind was a little blown here ngl
It took 30 years to happen but now I fear it will be imitated.
THAT could be a problem and if it is, the design will have to change.
Are there so many people outside who like to spend years in jail? I think not. The good this is, it is simple to identify and arrest such non brained person.
@@hesspet don't underestimate the people willing to throw their lives away for a spec of clout
@@hesspet It's also very dangerous for the plane. As a engineer you have to idiotproof your designes and this is a fault in that principle.
@@hesspet
People jump from bridges everyday.
After a BA smoke in the cabin incident back in the 1990s, it became a published procedue that we could open the 747 Door 5 Right below 1,000 to vent smoke. We were even taught to combine seatbelt extensions to hold the door handle in the cracked open position by a few inches. Never saw it happen in real life!
This is what they tried on the South African Airways 747-200M "Helderberg", which crashed into the Indian Ocean, to open up the door for a little bit to lighten up smoke. Sadly, it did not work.
Surely aircraft have better ventilation systems than to "open the door by 5 inches". Doesn't stop the problem at 20,000ft. Was the incident caused by a problem with the plane, or simply by passengers smoking? Smoking (cigarettes) on BA wasn't fully banned until 1998.
@@andrewmurray1550 it more for fire smoke
@@andrewmurray1550 It’s pretty hard to have a better vent than a large opening.
Also: planes fill with smoke during a fire very quickly. That’s why there is the design requirement for everyone to get out in 90-120 seconds.
You can find content on a pretty devastating incident where a plane in England burned on the tarmac with extremely high casualties because people couldn’t get out in time.
@@Canleaf08 That's an interesting idea. It doesn't appear in the inquiries so I am going to assume that someone, possibly you, just made it up.
Each of Mentour Pilot's videos is like attending a university masterclass, I learn so much and the explanations are so thorough and clear. Thank you Petter, you are a credit to your industry.
This is a big issue going forward. On the one hand, they need the doors more secure. On the other hand, the doors are meant to be open upon touchdown, in the event of an emergency. All it’d take is one emergency landing with a cabin fire, the doors not opening due to a new “safety” mechanism, and a lot of lives will be lost.
@@jensnobel5843you seem very knowledgeable on this. Thanks :) Do you have recommendations on videos / articles to look this up if I'm interested?
I wouldn't call it a big issue. Isn't this ultimately something that can very easily be solved by just not selling the seats directly next to the emergency exit doors to passengers? There's no need to keep an eye on them during cruise altitude since the pressure difference makes it impossible to open them, and during take-off/landing, they are out of reach of anyone not directly seated next to them. Anyone unbuckling and getting up to mess with the door during that phase would attract immediate attention by the cabin crew, which could intervene. I doubt this is gonna have any influence on how the doors are made to work and just affect procedure instead.
This already happened in 1980 with the loss of Saudia Flight 163. The cabin remained pressurized after a landing with an in-flight fire and all 301 people onboard died from smoke inhalation.
One of the reasons for the confusion over why the doors could open is that the media, and in fact the title of this video, continue to say the door was opened "mid-flight." As you so well explained, it could happen only because it was not "mid-flight" but at very low altitude.
“End-flight” 😝
It didn't happen on the ground. Quite dangerous when it did happen, for reasons mentioned in the video. It happened in flight at still high speeds and high enough above the ground to be fatal for anyone who ended up outside the craft, and risks to the control surfaces and, in different circumstances, to the engines. Having flown a few types of gliders, problems close to the ground can be more concerning than higher. I wouldn't minimize it.
@@bearcubdaycare I was talking about the public's understanding, not the danger. We've been told a door cannot be opened mid-flight, and that's true, as explained -- it wasn't.
90% flight, late flight 😂
Semantics. To many, I'm sure the term "mid-flight" is synonymous with "in-flight." And the plane was most certainly still "in-flight."
Your mate 74 Gear pointed out that in the movies in case of emergency many sheets of paper are released into the passanger cabins.
True xD
😂 I also love that the title of his video was something like “I lied to you”
I really love Mentour’s very rational, unbiased explanations with a lot of technical information described in a very simple way.
As an armchair aviation enthusiast who has never pursued his dream of flight for one reason and another, but still holds an intense interest in aviation, I really appreciate the detail you go into explaining things.
Coming from a cabin attendant on the type - great video with a lot of technical detail. I'm surprised the door managed to open, as the power assist on the emer exits is weak, or at least weaker than the one on main exits. I wonder how they'll deal with this in Asiana, where I fly we always need to chose and brief ABPs for unassisted exits in the cabin. Also I'm a bit surprised that this hasn't happened sooner, children or even adults get stupid ideas about those doors sometimes, hell we even had one lady confuse main door for the lavatory once. Then again it mostly happens higher up when seatbelt sign is off and pressure differential is higher.
Either way great vid, hope more people will see it
Thank you Dominik, I’m glad someone with your background found it informative and correct.
I think that's the point - for most of the flight it can't happen, it's only possilbe in a very small window.
@@tomriley5790 yeah fair point, though I'd day it's because people are busy looking outside the window during the landing/takeoff, not just because it's short period. If people are bored they get stupid ideas, the longer the flights the more annoying the passengers get.
I wonder if the flight being a short daytime flight was a contributing factor. If the passenger were instead stuck on a 6 hour night flight, he would have had time to adjust to the monotony, get numb from sitting in the seat for so long, and be tired and sleepy from the long day of travel.
@@theultramage it could be the case too, everyone is different afterall though from my experience the longer the flight the more problematic the passengers get. Nobody likes being stuck in a small, crowded metal tube for long
I was once in 1A on a A321. A woman took her 2 young children up to the toilet at the front, leaving a 2-3 year old boy to run around while she took her girl in first. We were descending to land before the fasten seatbelts sign was illuminated. After trying to pull out the catering trollies and successfully unlocking some of the them which the one cabin crew managed to catch the boy went to my side of the plane at the exit and made a huge lift on the exit lever. After all, levers are there to be pulled aren't they ;-) Anyway I was afraid that he might actually unseal the door and cause a painful cabin decompression, so I gave him a kick/shove with my foot to keep him away from the door. The door stayed in position and cabin crew dived over to grab him. His mother came out of the toilet totally unaware.
Did you kick him as hard as he deserved? And did the parents call the police when you landed?
I hope you gave him a Bruce Leroy kick
I generally kick or shove all children under the age of 12 when joining a flight in economy. You know you'll want to at some time, anyway...😁
@@memofromessex Nah mate because it didn't really happen at all. Obviously someone would leave a 3yo boy on therir own and nobody else on the plane would see them doing anything and stop it.....
@@memofromessex 😂
I look forward to a possible video about how the "extra" emergency exits doors on a 737 Max-9 work when it is fitted with an actual door (rather than the plug that failed on the alaska air flight).
I'm curious about how the plug function and opening functions along with where the emergency slide if fitted. Thanks for all the great videos and very professionally presented information!!

Your Presentation is Quite Interesting & have been following over a year. Keep up the good work, do well in life & our love to your 2 pet's. Abhijit from India.
Paratroopers (Jumpmasters & Air Force) open these "kinds" of doors every day for low altitude static line jumps so I knew that it was possible, but it would have to be at low altitude. The doors on the airplanes that we jump from (C-17s specifically) have angled shield walls and platforms that you can step out on when exiting the aircraft. (I'm not sure what the correct nomenclature is for those items)
So you don't get the "blast to the face" even when you are standing in the door as the first jumper.
Hell of a view though. Unless it is 2:00 in the morning.
I believe in that situation, the plane is also FULLY depressurized before the door is opened (by fully opening the outflow vents to dump any residual pressure before attempting to open the door). I'm not familiar with the operation or design of the doors on the C-17, but if I recall correctly, the C-5, C-141 and some other USAF planes commonly used for jumps have doors that are pulled inward during the opening process and then slid upward or to one side inside of the aircraft cargo/troop compartment instead of outward like most commercial aircraft so that no part of the open door is outside of the aircraft. I assume this is the case for the jump doors of a C-17 as well. Aside from the main boarding door on the left side of the plane between the flight deck and wing and the rear ramp, I think the other doors open inward. (I could be wrong, but that seems to make more sense.)
I never jumped from a pressurized plane. And pressurising the plane with skydivers could cause their AADs to mailfunction, so they usually turn them off in such a case, afaik
"It would be utterly impossible to open a door mid-flight"
_Boeing :_ Hold my bolts
Anyone that understands air pressure and how it increases as the plane is higher would know the answers to the questions asked.
Great job explaining and I love watching your videos!
God bless and safe travels
Panic attacks, intrusive thoughts, and the "knowledge" that "nothing is going to happen", go a long way. I remember playing around with the door handle in the car as a child. I played around for an hour on the drive to the vacation destination, knowing that as long as I don't pull enough, the door is not opening. But it did, and the next years I spent with the child safeties on. Ugh.
Unrelated but years ago there was a kid with his parents boarding a 747 in Australia and he grabbed onto the control stick for the jetway. Unfortunately it had not been turned off and it moved the jetway and damaged the plane door. The flight had to be cancelled and a replacement door had to be flown in. Very costly, tens of thousands of dollars overall from what I remember but I don't think the family was charged for it.
@@StevePemberton2oh man, such a shame that that family got away with it🙃 I'd be ashamed if I were the mother and try to fix things😅

LATEST NEWS FOR @Michael Duncham !!!: Diabilities and consequences of disabilities can differ! For ppl with more than Hommer Simpson IQ, there's no news at this time.
Airbus: our door can be opened...
Boeing: hold my door, seriously it's falling...
Having worked on a320 and A321 aircraft, I always thought this would be possible, as opening the doors made them rise up out of all the latches around the edge, before they move out and sideways. Obviously when there is no or negative differential close to the ground. It’s not good to see it happen though.
I asked ground engineers a few times about B757 and B767 aft-of-wing emergency exits as they are hinged at the bottom and seem to just hinge out. They didn’t know, but from your info they likely have an interlock.
There is one thing I would love to know .. why is there a ‘fasten seatbelt’ light in the PSU panel of the B737 that you would only see lying down .. this is about row 11 on -800 aircraft I have been on recently. This is in addition to the usual lights visible when you are seated.
Thank you so much for the explanation. As soon as I saw this news story I told my girlfriend, “Mentour Pilot will likely do a video on this, and I can’t wait to see it!”

I'm the wife of a 6'5" husband and we're often seated next to the emergency exit doors. I can honestly say I have never looked at the door and wondered if we could open it in flight!
I really like Petter's cosy, story telling corner - it kinda lulls the listener into some kind of safe feeling, despite the scary topics ✈😨🛩
The production quality of this episode is crazy!
Thank you! I’m so glad you thought so
Agreed! Our compliments to those who handle your graphics.
@@cod-the-creator Really?! Why do you say that?
I mean, obviously this is a story about an incident that has just happened. But I was personally quite pleased with how it came out. I would love to hear what’s you thought was so wrong with it?
TL;DW: Exceptionally low pressure difference during landing, a armed emergency assist, a smaller and unguarded door. And someone with way too much determination.
I come and go from this channel, binging and then waiting more more videos to listen to while working. It always seems to be shortly before needing to fly for work. 😂
I've never been a nervous flyer in all my 50 years. I have to say though, these videos sure are working on it.
Same. 🎉 Go us for facing the fear!
I def have to be careful with CZcams videos about air disasters. You can click something to make them stop showing up on your page if you want.
@@kiwimusumeits impressive how this pilot from this channel still keeps flying and getting on planes without developing intense anxiety from all this kind of content
As a now-disabled senior, I won't be flying anywhere cuz I don't consider myself a safe passenger for emergency evacuations. But with an aerospace background on DC8s & 9s from the 60s/70s, I appreciate your detailed explanations !!!
Even as an Airbus Pilot, I am quite sure that the DC9's (At least the -80s) had the door system where it would fold over itself and the inside of the door would be showing out when it was opened (like a hinged door). I think it would be much harder for it to actually open in that case. What Petter got slightly wrong was that on larger Boeing aircraft (B787/777), the door functions like on the Airbus, sliding outwards instead.
@@thejailbreaker8675 I don't remember. As the designer/analyst for the computerized FAA-required provisioning system, I knew the parts explosion and the maintenance schedule like the back of my hand. Now, knowledge and memory fails...
What about the squat switch, which is used in aircraft to detect weight on the landing gear so that certain systems can ONLY be operated when the aircraft is physically ON THE GROUND ??
From an engineering point of view, we have a saying: "If you try to make something fool proof, nature will just invent a better fool."
While that might not sound very nice, it actually has a more complex meaining. While you can try to think of all possible things that could happen to your design, it's unlikely that you can consider every single circuumstance that might occur. In the end, the part is only as good as the circuumstances you were able to predict. That should not mean that you shouldn't try to make it as perfect as possible, but you will likely never cover it all. And since over-engineering is a thing, you have to compromise to what is reasonable in terms of functionality, safety, maintainability and costs. Especially safety is a tricky subject. What is safe under one condition might not be with another parameters, but only one failure might be necessary for a disasterous outcome.
On the other hand it advises you to be cautious. It means that you can't rely perfectly on any piece of engineering and have to monitor performance and need to look over feedback etc. constantly.
That's very good insight!
Exactly - you can never design for every possobly scenario - After all, when Microsoft were designing the security on the Xbox360, nobody could have ever anticipated that some enerprising hacker would actually drill a hole into the security chip in order to sever the security connection!
We design things as best we can, trying to anticipate every realistic scenario, but sometimes, something comes way out of left field that nobody could ever have thought of...
I love this channel. The only thing is that a question that could be answered in less than 5minutes take whole 17 minutes
There is always a choice.
If I choose to explain these complex incidents in less time, it will mean skipping important underlying factors which makes it understandable for people with less background knowledge.
Remember, just because You understand something, doesn’t mean your mum will.
That’s why I try to be as thorough as possible with my videos.
Im sure there are other channels who explain these things quicker and in less detail, if that’s what you are after.
Have a great day.
@@MentourPilot oh...yes now I understand thanks. Background knowledge is very important some people may not have it. Me too in other fields I do need a lot of explanation ( background knowledge ).
Thanks once again...I truely like your channel.
I honestly astonished the door was so minimally damaged, seriously strong design there
When it comes to assigning blame, it is best to wait for the final report. However, a incident like this that teaches the viewers about physics, design, and engineering, without assigning blame with the exception of a known fact (a passenger opened an aircraft's door in-flight), can be safely discussed before the final report is issued.
In addition, kudos to Petter for stating the situation that the door opener was experiencing (possible stress due to employment loss) and likely mental illness. When this incident was discussed on other forums, there were some people equating the perpetrator with a terrorist and proposing that he should have been pushed out of the aircraft.
It's the internet, people always call for the closest equivalent to a public execution they can think of in the safety of outraged anonymity. I wouldn't attribute too much value to that kind of talk.
@@sleepysera Reminds me of when my country's Miss World was later found to have been charged with shoplifting, & 1 of my schoolmates commented that she should've been thrown into a river & fed to fishes
Thank you for the excellent explanation, Petter. As a Korean who flew and very much likely will fly on Asiana, I was quite worried when I saw the news of this incident. Thanks for the explanation and keep up the good work!😊👍
On a side note, Even though I know that emergency exit row seats are highly desirable for the legroom and airlines profit from the extra few dollars that they can collect from the seats, I believe that keeping the exit door handle in arm's reach from the seat was at least part of the reason why this incident happened so quickly. Maybe requiring airlines to distance the seats right next to the emergency exits from the doors a certain distance(at least out of arm's reach) might help?
@-o1008
The fact that your English is better than 99% of my fellow Americans' depresses me greatly. Well-done, you! 🙂
@@lisahinton9682Thank you! I had the privilege of learning English in the US when I was little, so nothing to be depressed about here! Without your people's help, I would never have been able to watch Petter's wonderful videos, much less reply to your lovely comment :)
This is lovely.... The explanation was so detailed that it appeared as though I was watching a livestream of the incident.
Keep up the good work sir.
Hey, I have been watching all your videos on aviation accidents/incidents and they really are binge worthy. The amount and quality of technical information and professional observations you give are truly outstanding.
That being said, I would love to see you make an episode about Independent Air Flight 1851, that crashed in Santa Maria Island in Azores. I find it an interesting one since reportedly there were multiple causes to it, which immediately reminded me of the cheese model you talk about so much in your videos, and also because it happened in the Azores, where I was born and have been living most my life. Anyways, thank you for all these hours of story telling and learning you have come to provide, fly safe!
On a side note : This is also the reason why spacecraft like the International Space Station, Orion, Soyuz etc. all have inwards opening airlock doors/hatches which ensure that they can never open accidentally due to mechanical or human failure. The pressure differential between the spacecraft and the vaccum of space makes this virtually impossible. The otherwise very good movie "Gravity" starring Sandra Bullock for instance, show this completely wrong with outwards opening hatches on the ISS and TianGong , which for outlined reasons do not exist. ;-)
Great info! Thanks
How did the freemasons get out to play golf on the moon all those years ago?
always better to have physics help you than to fight against it 🤣
@@MattyEngland You depressurise the airlock, which makes it a vacuum on both sides of the door.
Dragon and Apollo (after Apollo 1) have outward opening doors.
The reason I feel safe when flying is quite simply because of the pilots.
The way I see it, as long as they want to go home they will do everything in their power to land safely.
And that keeps me safe too 👍
True that, but that does not prevent pilot error
Cheers
Mostly true, but if you look into the past....pilots have cut corners on procedures cause they got impatient and caused disasters.
@@acidgambit8138 Fair comment.... but who put the bad pilot in a position to be flying other people. I hate the phrase "pilot error" because a bad pilot or a poorly trained pilot was hired by an airline despite their inadequacy.
Your life in an airlines hands
And you should be able to expect on any form transport you buy a ticket for is operated by someone who is competent and fit for purpose
I appreciate your interaction and civil manner but I also anticipate some backlash from haters
@@tomdavis3038 I hate the phrase "pilot error"
Who puts the pilot in the cockpit?
I don't include you in this statement because you have been civilised in your comment.
But I also expect backlash from people who simply think pilot error is the reason
Again I ask the question; who puts an inadequate or poorly trained pilot in a cockpit?
Not the case with Egypt Air Flight 990, Malaysia Flight 370, and that German one that crashed into the Alps (I don't remember the Flight number on that one). It's certainly why I don't like some calls to reduce the number of pilots to 1.
Yet again Mentor is the place for so much technical detail yet very understandable and not too overwhelming to follow. Thank you!
This is similar to the story about trash bins in Yellowstone Park (I think), where they have to make it bear-proof while still human-usable. The problem is there is a good technical overlay between the smartest bears and the dumbest humans.
Hahaha!
Not just in Yellowstone Park and not even only in National and Provincial Parks in general - you need bear-proof garbage containers (and food storage) in any place where bears live close by. That's not just in the outback, but also inside many towns and some cities in several U.S. states and in almost all Canadian provinces. Besides, bear-proof containers don't protect bears only. It already happened to me that i opened a non-bear-proof container to put something in and instead found a terrified raccoon that had trapped itself inside... 🦝
Elsewhere in the world, there are similar problems. I once read a story about a city in New South Wales where people have to secure garbage bins against a specific species of parrots and the trouble of the rubbish getting scattered all over the place keeps coming back because those parrots keep learning, getting smarter and smarter over time... 🦜
@@IngoSchwarze Yea I mentioned Yellowstone because that's the story I read about, but it makes sense that anywhere with bears has to deal with this. Didn't know about the parrots hahaha Thanks for the info :)
every time you make something 'as fool-proof' as possible, somebody makes a better 'fool'.
The moment i heard about the incident Mentour Pilot came into my mind, I SO WANTED to watch a video on this, Great work! You should do this more - make short/quick video about on-goings in avaiation and on recent incidents.
I will, if you guys like me to.
I’m actually really excited to do some different content than historical incidents and accidents
@@MentourPilot we would highly appreciate it if you have time to do this! I was checking out your video when the news came out. It would be very educational for the general public!
Very well explained, as always. I understood everything expect "inches".
Mentour Pilot, the current news channel, has emerged! Thanks for the video!
Not really. I will only do this when there is a clear, logical explanation and no one was hurt.
But I’m hoping to do more of them!
@@MentourPilot 👍
Oh I was hoping you would cover this one! That was fast too! Thank you.
I don't think there will be any technical changes due to this incident. At altitude so low emergency exits can still be used at some airports, so absolute pressure switch is a no-go. Electric locks controlled by engine rotation maybe. For sure we will not see emergency exits fully staffed, when airlines are already trying to limit staff members to minimum (I could even imagine PM being forced to do steward job soon).
I hope you are wrong there but we shall see.
there might well be a case where an engine is stuck on or the sensor gets disabled before an evacuation is called... any interlocks preventing emergency doors from being opened are REALLY problematic so hopefully there will be no need for them.
Tayla: I could see an alarm being added to the handle cover that's armed whenever the plane is off the ground. That way someone would certainly notice and hopefully stop them.
@MentourPilot if there would be any active interlock for sure there should be some backup override system accessible from passenger area. Emergency exits has to be operable even in case of crew incapacitation by people without airline training even in situations some (or all) systems are down. I can imagine, that interlock could freeze, rust, become INOP due to other faults or just be overlooked in maintenance. Given the fact, that cabin pressurization is the most important countermeasure at most vulnerable altitudes - we should only see ways to ensure maneuverability and some engine protection against deployment of front emergency traps. So topic is very hard and while one troubled person should not be able to take down airliner, one person should still be able to escape real danger.
As always A BIG APPRECIATION to your work, knowledge, skills and COMMITMENT to the airplanes/airlines business and all of us interested in it!
Be well!

Thank YOU for watching! Glad you liked it
I love it how you fully E explain in intricate detail so that your story is fully understandable. 👍
Thanks for video, people must remember the plane coming for landing and like you said, was only 650 feet high when he open the door.
The moment I saw this on the news I knew in my heart that this video would come 😂 didn't expect such a good one this soon!
My team and I have been working flat out this week to get it produced.
We always try and give that little extra in these productions, that’s why it takes time.
This video greatly explained my questions.. thank you sir 😊
Outstanding job,, Captain! Your videos are always so informative.
Just got smarter. Never knew about how and why you can’t open a door during flight. Thanks
That’s why I’m here. Glad you liked it!
From my previous interest in and from watching your videos as soon as I heard it happened at such a low altitude I knew it had to have at least partially been possible because of the pressure on the door not being as much as at high altitudes. I didn’t however know about the extra gas cylinder assist when the doors are armed and that made it all the much more possible.
Thanks for the confirmation on my thinking, the additional information and great video explanation!
I think the important thing here is Captain Petters explanation and assurance to any nervous flyers is that although the passenger was able to open the door, no one's life was actually endangered. At cruise altitude unless a heard of elephants was onboard, the opening of the door was totally impossible. Like Captain Petter, I look forward to the investigation and recommendations (if any) are made by the investigation team. I trust Captain Petter you will do a follow-up to this when more information is known.
I watched another video explaining the reasons the door was able to be opened. I really like the way you fully explained it. Way better than the other one I watched. Kudos and keep up the great work
I love that you made a video on a very recent event! I was wondering if you would eventually make one, but so happy we are watching it today!
If no one is seriously injured, and I think I can add something to the story, I will.
Thanks for watching
Quite shocking! Thanks Petter for sharing!
You're very welcome!
Great explanation Petter. Thank you.
I found that very informative and why certain things different happen. I was for years a bit of a nervous passenger, but only during take off. I watched some of your videos and it made sense and now I am far more relaxed when flying and enjoy the experience more. You do a really great job. I just now have to get my sister over landing, which she always hates, but once down she is ok. I love your videos and always watch the new ones you release.👍👍👍😊😊😊
Best explanation of this incident by far!
That’s what I aim for
Man, this story kinda hits my close to the heart. About 10 years ago I was flying back home after helping my parents move. There was a young lady with some form of social disability on the flight in the window seat next to me in an emergency isle. We started chatting early in the flight and i volunteered to help distract her as needed during the flight. After a fair bit of chatting she hugged my arm for comfort and took a nap. Initially I was a bit nervous with a total stranger sleeping with her head on my shoulder, but i decided what the heck. I didn't have anything on me worth stealing and it was only a 2 hour flight. After about 20 minutes of the flight attendants coming by checking on her and a polite head nod of approval from the Flight marshal that was on board and seated just in front of us (he later confirmed he was there to help keep watch on the young lady because the airlines knew of her disability) I started to nod off. Shortly after i closed my eyes another attendant came by with blankets, one of which she reached over and placed over the young lady... which unfortunately helped create a very scary moment. A few minutes later the young lady started to wake up and was briefly confused as to where she was... and still being not fully conscious, began to thrash about in panic with the blanket that she didn't know was covering her. Her yells scared everyone on the flight and startled me back awake. Thinking she was having a seizure, I shoved the lady in the isle seat out of her seat and moved us both into the isle thinking that i've always been told not to try to restrain someone during a seizure, but rather to try to move anything dangerous from their reach instead. However, as she got her arms free she started grasping at everything around her...which included the emergency door controls. In a moment of panic i faced away from her and leaned over her and against the inside of the plane and tried to body block her as gently as I could to prevent her from accidentally moving the door control. In hindsight i realized that was futile as we were in-flight at that moment but I wasn't thinking clearly. The air marshal and attendants came shortly after and I was briefly placed under arrest and moved to the forward most galley while they worked to calm the young lady, contact her caregivers, and eventually investigate what happened. Thankfully everything ended well once they got her in contact with her caregivers via the air-phones and she was able to explain that she just got scared when she woke up in an unfamiliar place and felt restrained by the combination of hugging my arm (made her feel like her arms were bound) and the blanket (that she wasn't expecting at all). I was released inflight, after a PA explaining to everyone what happened and that everyone was safe and we landed without further incident thankfully. But i was reminded of that because for a few moments i was genuinely worried about her opening that door inflight by accident.
Why on earth (pun not intended :-)!) weren't her caregivers sitting with her?
@@tomriley5790because it’s Amurrica and they give fuckall to keeping families and groups together on planes like they otherwise would prioritize on any other flight overseas?
why gods name was she seated beside an emergency door with a disability?
@@trevorjoneill707 This is the real question. On most airlines I've flown on sitting in an exit row is accompanied by an "are you willing and able to assist in an emergency?" and a required reseating if the answer is "no".
@@theanimaster In OP's story, he made it clear her parents weren't even ON the flight because they had to call them on the phone.
As always, a thoughtful and brilliantly explained lesson to those of us who are interested in the particulars of an aviation incident. Thank you for your time and effort in producing this!( if you come home and one of your children says " Mum, who is that strange man?", kindly reduce your schedule...)❤😊
Oh! Finally :) I was waiting for this one and you gave me more answers than I hoped for! I was wondering how the doors opened into air stream and now I know! Thank you and keep it up!
Thank you for this video Petter, when I saw the news report I did wonder if you would do a video about it. I can't imagine how terrifying it must have been for the other passengers, thank goodness no-one was hurt. Thank you for answering our questions 👍
My favorite part of the video was the detailed explanation of how the cabin is pressurized. I was always curious how this was done.
Hey Petter, great video, thanks. Please keep making them, it always takes ages for the final report and by that time, we have mostly forgotten about the incident. Your timely feedback on preliminary possible causes keeps the faith for the nervous fliers...
Thank you. But I can only do this when there is a fairly clear cause and no one was seriously hurt.
@@MentourPilot Got it, agreed.
This video was so informative, Thank You! for working on it and bring it to us.
I love your work.
Thank you for being here!
Glad you liked it!
I remember that during an onboard fire (I think it was the South African B747 in 1987) the pilots were able to depressurise the plane and fly slow enough so the doors could be opened a crack. Sadly the flight still ended in disaster.
Am so addicted to your videos Petter and have watched all of them. I enjoyed the technical part a lot in this video whenever i explain one of your technical parts to my friends they think am a pilot. I now love aviation because of your channel and your videos, you @Mentour Pilot and Kelse@74 Gear are my favorite aviation Channels. From Zambia centra Africa.
The amount of work you put into your videos amazes me every time. Btw great animations!
Glad you like them!
Yaay I’m excited to watch another video of yours! Summer holidays has been boring for me so far
Great work Petter! Please, if you can, continue with this kind of videos on this channel when an event like this happen 😬🙏🏼✈
This accident gives new meaning to "Suicide Door"😂😂😂
thank you. every time there is an aviation event i hope you talk about it
And I will keep doing that, as long as you have questions
Thanks for the fantastic coverage as always 🙏🏿
Thanks for watching! 💕💕
Thanks to Petter and his production team for pulling together a very professional explanation video with a very short time. The nitrogen gas assistance for opening the Airbus door was a detail that I had not seen before. I was wondering how the door could have moved so far forward in the wind.
I can understand that they will have to be very careful about making a modification that will slow down or possibly prevent opening the door in an actual emergency. An interlock that stops the door from being opened while the plane is moving would have to be very carefully designed to allow opening in an emergency, even if electrical power is lost.
I love your videos and your production standards are superb. Your dog is adorable. I do hope that you absolutely were not "literally bombarded" by questions though - it could be painful!
I loved this episode. It was so different and informative. You are really great :)
I loved this video. ❤ Super informative and puts my anxiety to rest.
Yep I hoped Mentour would cover this. Now we'll know what happened.
I hope you will like the video
I love how you explain things to people like me who are not pilots. Thanks 🙏
I am glad you've found the word -- "abnormal". We all learn from these series after all, thanks Captain. Keep the track towards the sky and never stop learning.
