I've thought this video might get me nervous around planes.
Now I think I am afraid of cars either.
I don't even think I would know what was going on by the time the 18 seconds are up... rip
You wouldn't know. It's actually supposed to be a pretty pleasant way to go. You feel very intoxicated then black out.
Bradley Noneofyourbizz so,what you’re saying is...you would have absolutely no idea that you are dying...?
No, not at all. Just as with medical anesthesia you might be very aware that you are slipping away. So, if you are aware of the symptoms you might know you are dying but it's not painful, by any means.
You’d know because an oxygen mask would be dangling in your face. That’s why everyone should pay attention to safety demonstration video before a flight. When a mask dropped, just don’t think and grab it like your life depend on it (well, it is); AND because there’s seconds before you black out, you should put on yours before helping even your kid (you can’t help anyone if you blackout)
never taking off my airplane seatbelt again, not even to excrete wastes
Lol why am I seeing a bunch of comments with like 4 likes
This is why I have my seatbelt on for the entire plane ride 😅
LifeWithErick
Try doing that for a 12 hour flight I don’t like my seatbelt on a two hour drive
Hi kuya Erickkkkkkk
Sameeeeeee 😂 plus I'm terrified of heights so I get so nervous when I go in a place
Aaron Smith You can wear your seatbelt loosen, it’d be comfortable but still prevent you from getting thrown up to the ceiling
I'll just take the bus...
The Ace Of Spades thats worse in my country with an average of 5 bus accidents per day
But, why? He literally just said in the video you're way more likely to die in a car accident. I know you're joking but I've never understood aviophobia.
The Ace Of Spades to another country😂😂😂
Well, you don't understand and neither those who have them because phobias are not rational, they just happen.
You mean the Airbus?
Darn, I can only move 2 African Bush Elephants. Well there goes _that_ idea. 😅
adam mac 😂😂😂
Sooo, a mouse is enough to move the elephants... enough to open the door (!?) New rule: no mice on commercial aircraft.
Lenard Segnitz sir, we have found mice in your bag, please wait in this room for further questioning 😂
n4gauge ehhhhhh that’s mean
You wouldn't get sucked out of the plane. Some small loose articles might fly out, but Mythbusters tested the explosive decompression thing. It has very little power behind it and the pressure change lasts only a moment so unlike in some stupid movie called "US Marshalls" you will not have a continuous vacuum cleaner effect. I want to write that James Grider busts in rage a window in a jet airliner he is in by spawning the Wykkdik of Fhekris through the panes. People should buy my "Impact" a James Grider novel on Amazon so I can afford a used car.e lasts for only a moment.
I love your voice crack at 2:28
I think your throat is getting dry. Have a glass of water.
Drink Water my throat was actually really dry when you said that
Drink Water it actually was im getting water
Drink Water a great reminder, thank you
I think even if you DIDN’T say that, ASAP Science wound know because of your name!
Drink Water hail hydra
This is great for my anxiety yay
get your shit together, then u won't have anxiety bullshit in first place. then try traveling
plane doors are also opened to the inside of the plane and the hole is smaller than the door itself. You have to PULL to open the door, but the pressure inside the plane is basically pushing the door shut. Kinda like trying to push a big object through a small hole. Can't do it.
Some people are much more susceptible by anxiety than others. Its not just a mindset, it's like it's hardwired into the brain.
kols3332 sorry to say, it’s not that easy.
kols3332 I’m not even going to try to explain how much of a fool you are. My time won’t be wasted on some dumb troll.
0:20 to 0:30 might lead to a MISCONCEPTION: the atmospheric pressure varies with altitude not only because they are pulled stronger by gravity at low altitudes and weaker at high altitudes, but because the air column above every molecule also exerts force (superposed with gravitational pull). In fact even if the gravitational field had the same acceleration regardless of the distance from the Earth, the pressure would still change with altitude. If any math is required to explain, please reply.
yea, totally
Actually gravitational force (and thus acceleration) does depend on distance. But the difference between 0-10 km is quite minuscule.
True, but we don't even need to go as far as 10 km. 3 m underwater adds about 29430 Pa of manometric pressure (1 atm = 101325 Pa), and what is 3 m relative to the radius of the Earth? So we can assume that the acceleration stays the same at 9,81 m/s².
headed to comment section for this ! thank you for pointing it out.
Imagine if they actually play this video in the planes before take off...
M&M's may you sub to me? my channel lit i promise !!!😂
M&M's Well then according to a lot of people in this comment section they will be showing false information
Hey bro, wassup
Goddamn, for sure the airline would go bankrupt because no one would ever fly again..hahaha
GARYSHAWN No.
Nearly impossible to punch and break an airplane window?
Hold my beer
Can always count on you guys to answer some of life's biggest questions. Thanks for that.
I can feel the sarcasm all the way over here
Filtered not nice
Actually, I'm now more worried that the pilot will be having a bad day and open the doors from the cockpit.
Will Brown that's exactly what i was thinking... Oh great...
adam mac OMG IKR! ASAP science make life easy and healthy for a fat hefty boy like me!:D
2:16 is completely false.
The windows are rounded not to reduce drag (they are flat with the outside panels anyway) but to avoid stress accumulation on sharp edges which, overtime, leads to cracks and catastrophic failure of the panels.
They actually linked to a video about this: [14] ua-cam.com/video/7rXGRPMD-GQ/v-deo.html
Thanks the comet for that. I have the impression that they rushed their video this time.
I counted 3 main mistakes :
"The pressure is higher because the gravity is higher" That's wrong. That's because of the weight of the air column above it.
For example, at the center of the earth, the gravity is canceled ( if there was an air bubble at the center of the earth you would float in seemingly weigtlessness, because you are pulled equally in all directions) but that's where the pressure is the greatest because all the materials above it do have a weight directed to the center of the planet.
"You couldn't open the door because of the pressure acting on it" Wrong again, as the pressure is greater inside than outside, the net force would go toward the outside, as the door open outward, it's actually HELPING you open the door.
"windows are rounded to minimize drag" You explained this one.
""You couldn't open the door because of the pressure acting on it" Wrong again, as the pressure is greater inside than outside, the net force would go toward the outside, HELPING you open the door."
Although I agree this video felt very rushed and was very poorly explained they are not wrong about this one, the passenger doors open inward thus the internal air pressure forces the door closed, it is physically impossible to open them outward due to the shape of the frame and door.
Yeah I saw that later... As I saw that the doors open outward, I jumped to the wrong conclusion, my bad. But how with the informations given in the video was I supposed to know there was a security lock of this kind :/ ?
It's not just a security lock. The doors area plug type design, causing increased pressure to hold it in place. You always have to pull on a door from the inside to open it.
I'm a flight attendant and we are actually taught this stuff during our trainings. Useful time of consciousness, cabin pressurisation, decompression.
Thanks for posting this vid. Amazing job 🙌
2 errors - In the event of a depressurisation aircraft will typically descend rapidly to 14,000ft (unless terrain is a factor) where passenger/cabin crew oxy will no longer be needed, however they will stay at that altitude to the limits of the cockpit oxygen (usually hours) then descend further to 10,000ft where they will remain there until destination. - All of this to save fuel. Secondly - There is no control of the electronic locks for the cabin doors in the cockpit. This function is automatic on all modern airliners - The only thing pilots get is a warning if the locks aren't functioning, in which case a cabin crew member will 'guard' the door until differential pressure is enough that the door would be impossible to open.
Steveth6 Is there even a lock on doors that prevent you from opening it? I thought when flight attendants “arm” the door, you can still open it with the slide inflated immediately. (I’m not challenging you, I don’t have a definite answer)
What would happen if the door burst open and the Kool Aid guy jumps in: “oh yeaaahhh”
He's there to take you to hell.
Lmfao. best comment ever.
The sweet release of death is cherry flavored.
giant juice drink monster cuases death of 234 passengers and crew. families are wanting justice.

These are usually pretty good but there are two sizeable goofs in this one:
First: 0:23 : air is denser near the ground due to hydrostatic pressure from the weight of the air above it. Gravity is not different enough between the surface and the edge of space (~100km up by convention) to cause the massive difference in pressure (2200000x) [2] because that distance is tiny compared to their average distance from the earth's centre of mass (6371km). [1]
Second: 2:10 : windows are rounded to eliminate stress concentrations at corners. This prevents cracks but has nothing to do with drag. They aren't sticking out into the airstream and so can't contribute to drag.
[1] Relevant equations here: en.wikipedia.org/wiki/Newton%27s_law_of_universal_gravitation#Gravitational_field
[2] en.wikipedia.org/wiki/Kármán_line
What about the big mistake at 1:40 ? The pressure actually try to help you open the door, not the opposite... As they open outward...
It's not a mistake because both are true. :P
You don't want the door occupying precious cabin space during ground operations so they end up out of the way somehow but you also want to make the pressure work for you. There are lots of different clever mechanisms to do this. Some examples from videos on youtube:
A) the door's left and right edges have slightly inward slanting features (narrower in the direction away from the fuselage) while the top and bottom edges are parallel to the direction of opening. The door opens inward, rotates around itself and then outward around the frame's hinge. In flight, the pressure holds the door up against lugs around all edges and is restricted against the initial opening motion by the pressure.
ua-cam.com/video/TUIsU9okKjw/v-deo.html
B) Door expands as it closes to grab top and bottom edges. Looks like the middle also goes down and behind some lugs in the left/right sides for the same effect as above.
ua-cam.com/video/vRwph9xzxf0/v-deo.html
C) Door pops in and slides up (works because fuselage is circular)
ua-cam.com/video/ovhJpY-WKGQ/v-deo.html
PointLineBox thanks for clearing up the force on the door. I was thinking the same thing as the other guy.
So planes have backward submarine hatches.
It's hydrostatic pressure from the air above you... due to gravity - cannot calculate hydrostatic pressure without g. They should have worded that clearer I'm sure.
I’ve been watching these videos whenever I am bored and they are finally on trending, I love this channel.
Without watching the video I have concluded that I will die if the door bursts open...
tell me if I'm right.
Isaac Argueta-Valle you are
Isaac Argueta-Valla CONGRATULATION! You got the right answer here’s your prize! ->___
Not exactly, you might die, you might not. Here are 2 examples:
Turkish airlines flight 981 was flying when its cargo door blew off. 6 passengers got sucked out of the plane because off decompression and the rest died on the crash.
Wikipedia of flight THY 981:
simple.m.wikipedia.org/wiki/Turkish_Airlines_Flight_981
Another example is aloha airlines flight 243. its whole roof blew off but everyone survived except for one flight attendant, who got sucked out of the plane. There was many injuries but here it is on Wikipedia:
en.m.wikipedia.org/wiki/Aloha_Airlines_Flight_243
Thank you for reading this far.
Anyway, like he said in the video if you are trying to open the door manually you might as well be pushing three elephants and an electronic lock is keeping it closed.
In short, you might die, and you might not. Just hope that you won't.
Sorry for making you read this ridiculously long reply on your question but I hope this helps.
So unlike the other comments saying "correct." Well, there's a different side.
So short short story I'm trying to say to the other comments:
"HA YOU'RE WRONG"
lol I appreciate it, thanks.
👌
18 seconds? Damn.
Vaibhav Kulkarni That is why you put your own Oxygen mask first.
Boarding a plane in 10 minutes, so thanks for the heads up. :D
SORRY! But at least you know how hard it will be for the door to open now. :)
AsapSCIENCE, I wasn't being sarcastic. XD I personally love flying. But thanks for debunking the myth. :D
Maria Camilla Thiago, They were triumphant! :D
I'm surprised that this video neglected to mention that doors on large aircraft actually open to the inside. It acts as a plug, with the air pressure inside the cabin sealing it against the airframe. A pressurized cabin _helps_ the door stay in place.
Love you guys! always killing it!
Michael Goodrum nah this video is terrible. Many falsehoods in this one.
The windows aren't rounded to reduce drag, it's to redirect stress on the fuselage around them
My day would go *ajar*
The Science Biome As a man of puns myself, even I must admit that one's a bit of a stretch lol
Hopefully those with the Wright attitudes with make better puns.... it's in the air now. Cleared for take off on the punway! Hopefully it takes off. And I give props to those who try.
P.s no 9/11 jokes, those are plane wrong
22640cal you're a legend lol. Do you mean Wright Altitudes tho? ... Puns always make you look trying too hard sadly
22640cal LMAO is your name how much I need to eat in a day to be as clever as you?
Lord 😂😂😂
I love these guys so much they're so disarmingly cheerful
Disagree with what you said in the early part of the video. The atmospheric pressure decreases as you increase altitude because there's less atmosphere(weight) above. If you take a 1" square column of air that goes from sea level all the way up to the beginning of the Thermosphere, that column would have weight. The higher up you go, there's less weight of the air above. The only thing the Earth's gravity does is keep the atmosphere in position. The way aircraft doors are designed, which is like a plug from the inside, it would be virtually impossible to open the door once the cabin is pressurized.
electronicsNmore well said
Well, the fact that this column of air has a weight is of course due to Earth's gravity.
YES. This is what I was looking for. Even though I think it was in the later part of the video. I disagree with the way the cabin pressure was explained. Since the pressure inside the cabin is far bigger than the pressure outside, if the door opened outwards, then it would be extremely easy to open them if there was something wrong with the lock mechanism, but since they open inwards first, you basically have to lift a shit-ton to pull the door inwards and then open it. A plug is a great analogy, actually.
I heard the explanation and started to think that it doesn't really make sense and dug a bit.
Abi Gail That's true, but it wasn't the best way to explain it.
John Doe LOL.....You must be a Bernie or Hillary, they love using that line.
The air pressure is higher in sea level because of the column of air above, not because gravity is stronger. You see at the ISS at 400Km altitude the gravity is only 12% lower then at sea level and air pressure is practically zero.
Round windows are for diminished stress of the airframe. Comets started to crash in the 50's because of square windows. More info on the channel RealEngineering. I disagree with the reduced drag affirmation.
Roberto Horn soo, any published science links?
Roberto Horn NERD!!!!!
About the pressure it's basic physics:
From Wikipedia:
Hydrostatic pressure
In a fluid at rest, all frictional and inertial stresses vanish and the state of stress of the system is called hydrostatic. When this condition of V = 0 is applied to the Navier-Stokes equation, the gradient of pressure becomes a function of body forces only. For a Barotropic fluid in a conservative force field like a gravitational force field, pressure exerted by a fluid at equilibrium becomes a function of force exerted by gravity.
The hydrostatic pressure can be determined from a control volume analysis of an infinitesimally small cube of fluid. Since pressure is defined as the force exerted on a test area (p = F/A, with p: pressure, F: force normal to area A, A: area), and the only force acting on any such small cube of fluid is the weight of the fluid column above it, hydrostatic pressure can be calculated according to the following formula:
p ( z ) − p ( z 0 ) = 1/ A ∫ z 0 z d z ′ ∬ A d x ′ d y ′ ρ ( z ′ ) g ( z ′ ) = ∫ z 0 z d z ′ ρ ( z ′ ) g ( z ′ )
(the format was ruined, look it up on the wiki)
where:
p is the hydrostatic pressure (Pa),
ρ is the fluid density (kg/m3),
g is gravitational acceleration (m/s2),
A is the test area (m2),
z is the height (parallel to the direction of gravity) of the test area (m),
z0 is the height of the zero reference point of the pressure (m).
For water and other liquids, this integral can be simplified significantly for many practical applications, based on the following two assumptions: Since many liquids can be considered incompressible, a reasonable good estimation can be made from assuming a constant density throughout the liquid. (The same assumption cannot be made within a gaseous environment.) Also, since the height h of the fluid column between z and z0 is often reasonably small compared to the radius of the Earth, one can neglect the variation of g. Under these circumstances, the integral is simplified into the formula:
p − p 0 = ρ g h
where h is the height z − z0 of the liquid column between the test volume and the zero reference point of the pressure. This formula is often called Stevin's law.[2][3] Note that this reference point should lie at or below the surface of the liquid.
10Km flight altitude is about 0.15% of Earth radius, so it negligible. The formula p − p 0 = ρ g h can be used in which g is a constant. It's not g that influence the pressure, only the altitude.
About reduced drag from round windows... That's the problem. There is no research on window shape and the drag they cause.... I can't see why it makes sense. The video further reading does not explain that as well. If you find something share it with me.
Graphic of g x altitude : en.wikipedia.org/wiki/Gravity_of_Earth#/media/File:Erdgvarp.png
Graphic of atmospheric pressure x altitude : en.wikipedia.org/wiki/Atmospheric_pressure#/media/File:Atmospheric_Pressure_vs._Altitude.png
Attention to the axes. one is in Km and the other in m.
Roberto Horn àqqAqQq
When did they say that it’s because gravity is stronger? I only heard them say “because gravity pulls on the air molecules” which is correct since the weight of the air above them is due to gravity acting on the air molecules above them
I have always wondered what would happen
JayJay the Makeup Boi i think air crab investigation has some videos like this. Everyone close to the door dies and the rest survive in most cases.
Are air crabs edible?
Nyi Nyi Htun LMHO
Alan Alban That sounds painful XD
JayJay the Makeup B
AsapSCIENCE I started watching your videos about just an hour ago and I really can't help myself to watch more and more of it, it's already 1:30 in the morning and I still have 8 am class haha. I just subscribed to your channel and yeah I just hope to extend my appreciation upon discovering it. :) Looking forward to be more entertained and more knowledgeable for the next days with you guys. Thumbs up.
Love all the extra plane facts to put people at ease. Nice video!!
News report in 2 weeks: Crazy man opens airplane window after seeing ASAPSCIENCE VIDEO. Lawsuit pending
LOL inside job
Sim Sim 9/11 comments incoming
this crazy man can also move 3 elephants if he wanted, apparently
You need a force of many elephants to open an airplane door midflight. Your joke doesn't make sense.
redstone craft guy He said window.
please note: you hear on the news about EVERY plane incident. Imagine if they reported every CAR death daily...
Its been yearss you still havent changed......Thank......You
Yess u guys uploaded !!
2:09 the bullet still has the caseing on it!
James Maron
And the windows are not bullet proof. It was on mythbusters
That may be true... But the combination of the layering and air pressure standard 9mm and many sub sonic ammunition won't have enough inertia to penetrate all the layers.
I'm a flight attendant and I approve this video.
We feel official now! Free flights for life?
AsapSCIENCE if you ever come to Europe, sure :D
Lydie Bousch me too! ;)
You would probably die because flight attendants generally are not in a seat with a belt. So...fun!
Scallywag yes we do. We are seated in jumpseats with harnesses around our waist AND shoulders. Stop watching old movies and get out in the real world, this is the 21st century, OF COURSE everybody is safe in an airplane.
You 2 are so adorable. Thanks for all the great videos!
Congrats for getting on trending!!
Oh just make me more nervous to fly LOL!😂
Crevetta Actually, sense you never fly as much as you drive, of course it's less dangerous. granted, you don't crash mid air but still. if everyone flew personal planes it would be way more dangerous but not as dangerous because you don't have as much risk of crashing.
Crevetta If you read my comment I said that. I am aware that crashes are less likely in the sky.
XxMemekipxX last name It's normal for people to be more scared when flying. What do you expect? It's rare, but plane crashes are more dangerous than car accidents are they're a lot more scarier too
Tech Freak this comment literally doesn't matter because it does not apply to the real world. If there were billions of planes in the sky then no shit it would be more dangerous. But we live in reality and the truth is you are much more likely to die whenever you step foot in a car than in a plane
The thing is even though flying is statistically safer compared to other forms transportation, once the accident strikes your chances of survival are very slim. In the event of a plane crash you will likely die on impact. Your chance of survival may increase or decrease depending on where you are seated in the plane, and the angle of the plane when crash landing. At least when you're driving a car you have much more control over it, as a passenger in an airplane you do not. In conclusion, the fear of flying largely stems from two things: 1) lack of knowledge regarding how airplanes function and operate, 2) the fact you have no control over the plane if something were to happen, meaning your life is effectively in the hands of the pilots.
I don't understand the 114 statistic is that the chance of being in a car crash through your whole life or each time you get in a car or something per distance travelled?
Thinking about it... I'd say there a chance you'll be in a car accident once every 114 journeys.
WELL I HAVE BEEN IN MORE THEN 114 JOURNEYS AM I GONNA DIE OMG
I think they meant that a car crash leads to death in every 114 cases. It's confusing as they present it but alternatively:
- Every journey has a 1/114 chance of a crash. That is way too high, certainly car crashes are far less common.
- Everyone has a 1/114 to die in a deathly car crash. This statistic also seems too steep.
In conclusion they would have to mean what I said, but it seems strange to me too.
Well it said life threatening so i think it means out of 114 car accidents, 1 leads to death
The all powerful google has given me some clarification here.
It seems that the statistics are over a lifetime of regular conditions, so according to the report, 1 out of 114 total deaths are due to car accidents while 1 out of 9821 deaths are due to airplane accidents. The exact numbers depend on the year and I'm not sure which year these numbers were pulled from.
Going to have a nightmare about this tonight. Thank you ASAPSCIENCE
U guys make me so happy
This video does contain quite a lot of errors unfortunately :/
wezpaa | true, air pressure does not decrease due to less gravity, the plane would not break apart, that's not why the windows are rounded, ...
Excellent work as always, guys :)
AWWWW warmed our lil' hearts on a Thursday.
I like the severity of this video matched with casual background music
Thank you for this!
I usually get paranoid about that sort of thing happening whenever I'm on a plane, and I think this helped me a lot!
Again, thanks! :D
I’m going on a plane in two days and this vid gets released...
Just to add... Plane doors open inwards that's why you have to use that much force to fight the pressure difference to get the door open in flight.... which is pretty much impossible. At lower altitudes, where air pressure inside and out are equal... that's what the electronic and mechanical locks are for to prevent people from opening it.
So you'll be more than fine :) Planes are super super safe.
Alan Sabu Mathew lets hope it is :)
It is a sign .. cancel your flight
Jill Austin I need to go back to my country )):
Nam Nguyen swim there or come to me .. i will welcome you ❤️😂
2:00 "It would almost be nearly impossible for someone to punch and break through an airplane window"
So it's possible?
Don't Read My Profile Picture because nothing is impossible :p
Don't Read My Profile Picture he said also not almost
Don't Read My Profile Picture I saw you once in the comments section of a different video I did everything it said not to do. I must say it was the most ENTHROLLING segment of BOREDOM in my years on Earth.
Bryan Fullbuster can you fly without help from a machine?
Can you levitate things with your hand?
Can you summon things out of thin air?
Can you make an Boulder explode with your bare hands?
No, that’s because not everything is possible.
Don't Read My Profile Picture well if you got a nuke and and put it next to the window. Yeah, but don't you think someone's gonna see you putting A FREAKING NUKE next to the window?
It's that one that always gets you...
Crazy how something similar happened with that Southwest flight this week...
Reminds me of the woman who got sucked out of the window.. RIP🙏🏾
*i sentence an idiot to open the plane door and everything starts to get out except the people seat belted*
"HA! A-atleast i have my seat be-
*Plane breaks apart*
Hint: Planes are not designed to fly with the doors opened. Or above a certain speed. Or above a certain G-load.
tbh, this actually really calmed my nerves about this subject. i mean, i figured it was probably unlikely but i didnt know HOW unlikely, so thanks as always ASAP Science!
Way better than science class
Wrong information about the pilot locking the doors from the cockpit.. it’s the responsibility of the cabin crew but it shows on cockpit to confirm for the pilot to be ready for takeoff 🛫
Lmao I thought cockpit was an insult word
Maria Camilla Thiago I’m a cabin crew for 10 years now and I’ve flown enough types of aircraft and get training on them to know.. we are the ones who is responsible for closing and opening the doors in normal and emergency cases..
Why not fly lower in general?
Nick Slayr Music Because it burns way more fuel to fly lower due to more drag, you fly faster at high altitude, and jet stream winds help you go even faster
I like how the bullet slug was traveling with the shell still attached. Very accurate.
Can always count with you to answer some of life biggest questions.😊
Im watching this on a plane lol!
Die hard Trulexovac where are you traveling? :)
Open the door
how
Die hard Trulexovac im sure u lying
Glomo 😂😂
How does having rounded windows decrease drag??
They don't, they just smoothen out tension lines reducing the maximum stress on a given point, decreasing fatigue.
I feel so smart watching this!
Can you do a video like this about what would happen if the elevator cables snapped? Or how safe they actually are to calm my fears of elevators. Loved this video
I'll just take a Uber cab to Hawaii.
remember u r more likely to die in a car!
If I fell I'd aim for a pile of pillows...looks like my chances are very slim lol.
Also for any gamers out there, I make copyright free music and I need your brutally honest feedback! (You won't hurt my feelings😂)
Great watching this while waiting for my flight
Round window corner to reduce drag??? Or to reduce the corner stress acting onto the airframe skin?
@AsapSCIENCE So, sorry to say this but this is pretty much false information. a whole plane emptying itself will not take passengers with it. There is however a chance people literally right next to the door would be blown out if they dont have seatbelts on. This topic has been covered in so many science classes and videos. Your information given in this video is wrong and u should remake this video with factual information.
totaly agree
And I would like to add that most aircraft doors do NOT have an electronic lock on them that the pilot can engage or disengage. This is experience from a prior aircraft maintainer. Those that do were made within the last 10 years, but most companies just refit older craft with newer parts and such a modification is VERY expensive.
Thank you, my good sir.
Also been tested by mythbusters and its not what happened. With high pressure inside and low outside of the plane
And I'm pretty sure almost everyone can hold their breath for more than 18 seconds without suffering hypoxia.
There are a fair few incorrect "facts" in this one
That is so cool; awesome video. :)
Great video!
Science!😎😎😎
Strange watched iron fist yesterday with Danny rand and his plane crash and now this comes up, what a coincidence!
I know man tell me about it
Iron fist is good #MyNameIsDannyRand
Hi how are you
0:16 now he just put a thought in my head
LOL LOL LOL🤬🤬🤬🤬🤬🤬✌🏾✌🏾✌🏾✌🏾🖕🏾🖕🏾🖕🏾🖕🏾🖕🏾👄👄👄👄😂👄🍆🍆🍆🍆🍑🍑🍑🍑 💦
Wow y'all r some great artists too
Please explain what happened with the South West accident!! We want to know!
But I can hold my breath for longer than 18 seconds :/
Good luck holding your breath with the air in your lungs suddenly expanding... :-/
holding you breath under water is different from holding your breath under decompression
Jackson Mcquade I really hope you are being sarcastic
Jackson Mcquade uhm cool? This is much different lol
Yay the metric system has been added in the video!
The windows are not rounded at the corners for reasons of drag, as they are already flush with the fuselage of the aircraft. I would recommend looking at the original version of the de Havilland Comet. It had squared off windows, and the focusing of the stress on the windows, due to the repeated pressurization and depressurization of the aircraft led to stress fractures that eventually caused them to fail, causing some high profile accidents. The rounding of the corners significantly reduces that stress, minimizing that risk.
okay, this raised my plane anxiety through the roof.
what do you mean by "1/114 chance to be in a car accident" is this 1 out of 114 people get in a car accident? 1 out of 114 times driving, the average (sample?) person gets in a car crash? Both of these seem wildly out of context and probably isn't a very meaningful statistic
Croze may you sub to me? my channel lit i promise !!!😂
I dont know where they have the statistics from, but according to Wikipedia an airplane ride is three times more deadly than a car ride. But since a plane ride is typically much faster and longer, it is safer both per hour and per kilometer👌
Croze this is exactly what I wanted to ask. Why don't they have links to their references as a minimum if they can't explain stats properly!
Murphy9904 exactly
Just to add... Plane doors open inwards that's why you have to use that much force to fight the pressure difference to get the door open in flight.... which is pretty much impossible. At lower altitudes, where air pressure inside and out are equal... that's what the electronic and mechanical locks are for to prevent people from opening it. But at lower altitudes... opening the door is just an inconvenience and just silly for the person doing it.
Edit: Notice how the newer Boeing and Airbus doors lift up slightly when you try and open them from the locked position. They're called 'Plug doors'. The physics is still the same.
They open outwards!! I’ve been an aircraft mechanic for 13+ years
drunkskunk2 I hate to be one of those people, but you edited post that's only 2 sentences long and missed a period?
drunkskunk2 them I'm sure you're aware that pretty much every Boeing and Airbus passenger doors open slightly inwards first and then swing out. Either way, you have to pull the door in first. Notice how the newer Boeing and Airbus doors lift up slightly when you try and open them from the locked position. They're called 'Plug doors'.
This is a quote from the A340 maintenance manual: The lifting arms of the lifting shaft (which support the passenger door in roller fittings attached to the door frame) move the passenger door a small distance into the cabin and then upwards."
Not all planes use plug-type doors that open inwards. The ATR, Dash-8, CRJ and ERJ doors open outwards because the stairs is attached to the door. The E-Jet doors also open outwards. The Dash 8-Q400 had a history of door seal problems due to poor design and cut price manufacturing.
Great thing to watch 1 hour before I go to the airport 😂
Hey, actual science. Sweet.
But if the higher pressure is in the cabin wouldn’t the doors have that Force pushing out on the door. I’m assuming that aircraft doors open in this would be why it’s so hard to open. But the emergency doors open out so there’s a lot Force pushing on that door to open thus helping the person not fighting against them. I hope someone could please clarify that’d be great!
Doors actually are like plugs. They drop into the looking rails which make it virtually impossible to blow open
What you said is actually true. In terms of pressure you are technically being "helped" in opening the door. It's other things that make it nearly impossible to open the door.
Dylan Kahn yes you are right, but the mechanisms in most doors use this to its advantage, the first movent a door makes when beeing released is inboard, into the aircraft, then from there it might slide left or move up inside the cabin. But if you try to open the door in flight the pressue will stop you making the first movement.
it will be a plane death... meh
This needs more likes!! Lmao!
Even though you just aggravated my flying anxiety by making me think of a scenario I had never pictured before, at least now I feel better for always having my seat belt on at all times except when using the restroom.
Liking this video purely because that nail polish was on point
So much for planning cross country to Washington and California. I'll take a anything that doesn't fly.
ElectroBlastLuigi but he just said you have a much greater chance of dying in a car..
ElectroBlastLuigi mabye he’s suicidal? Jk
RandomBossGamer lmfao
Lol
Airplane is one of the safest way to travel with the lowest chances of an accident happening. Did you even watch the video?
As soon as I saw the title of the video I thought "But their doors open inwards."
Unless you're trying to open the door with explosives you'd have to be freaking Superman to be able to open that door. Even the combined strength of everyone that would be able to pull on it that could fit before they got too crowded to fit any more people would not be able to open that even if it wasn't electronically locked.
Hi. I love all of your vids. I'd just like to give some constructive feedback. You said plane windows were more oblong to reduce drag, but that could be misleading. As someone who is training to pursue a career in aviation and personally know some aircraft manufacturers, the oblong shape of the windows is more to keep the stress in a roughly continuous path though the fuselage. Basically the rounded edges means that the stress flows more smoothly around the windows avoiding a point of concentrated stress. You were quite correct that the shape reduces the chances of cracking though. I hope you find this useful, and I just want to help make your content as accurate as possible.
Omg lol this video is so random but so awesome lol
2:08 "Airplane windows are bullet-proof" Demolition Ranch and other gun-related channels would like a word with you. Hint: they're not bullet-proof.
AsapScience Guys: There is an error in your logic. At 1:29, you state that the air pressure at altitude on the plane door is 17,505KG. And that 'you' would need to be able to push at least that much to even begin to open the door." There error is that at altitude, its *already* at 17,505KG of force, so why would you need to double that to 'even begin to hope to open the door' ?
The piece you are missing is the pressure rating of the door on an AirBus A380. Is it 17,500KG, 20,000KG, 50,000KG? Its the difference between the pressure at altitude and the pressure rating of the door that would determine how much force is necessary to open it by force.
I'm not sure about the 18 seconds for hypoxia to kick in either...
TLKR
ASAPscience on trending!
UA-cam is finally doing something right!
I never get tired of the music
Thank God I don't need to fly anytime soon
IM GOING ON A PLANE TRIP IN 6 DAYS D:
Akhil Parachuru did you survive
Wow seeing this after the Southwest flight incident....
Such a grim concept, made into a fun happy go lucky animation.
