Be honest, did anyone else think the equipment under their plane seat was a parachute?
Yea
I know someone who did.
I think not unless you're not listening to the Cabin Crew's instruction before boarding.
Not scientific though... but how about give the plane a parachute big enough to break its fall
I once flew in a 1930s biplane with an open cockpit and the parachute was embedded in the backrest. When you buckle up, you're actually buckled into the parachute at the same time.
Here’s the thing, not everyone needs the specialist skydiving equipment. Just me.
😂
“What do you mean I need to buy a ticket for my emotional support tandem sky diver???”
@EsteemedMortal According to the TSA "You may transport parachutes, either with or without Automatic Activation Devices, in carry-on or checked bags" so you wouldn't even need another ticket
That’s what I’m talking about!
@@redhood5074 he meant for his tandem skydiver(human) not for the equipment
This channel is specially designed to answer all those questions that I had when i were a kid and nobody could answer.
Thank you a lot for the effort and the love that you put in all these videos, I love them!
Thank you so much for that comment 😊
The answers he provides are not the ones adults need. However these videos are great for small children with adhd.
@@Make-Asylums-Great-Again What even are you talking about lol. They're perfectly explained for "adults"
He didn't answer anything, an engineer with an associate's degree could have told you he's wrong.
@@DebunkedOfficial you feel that good lying to people for fake content? How about you pay for an engineers opinion before you make a video that limits people's perspective. CZcams creators take zero responsibility for falsly leading the ignorant.
Can you imagine the human crush that would occur when the pilot gave the order to abandon? A plane would have to hold under 180kn at a reasonable altitude for quite a while with incredibly cool customers as passengers to have a successful evac. But if the plane is THAT controllable, it is also controllable enough to land safely.
At least a chaotic brawl might provide some level of distraction during an otherwise emotionally distressung time.
@@SofaKingShit It's the little things...
Imagine you hardly have space to move your arms but suddenly 300 people are supposed to get changed into this equiptment at the same time.
equipment?..a backpack with straps in a rare occurance to try to save ur lives...what a inconvenience...lol oh boy.
someone didn't watch the video
@@energygoeswhereattentionflowswhat is THE MOST important thing the flight attendants tell you not to do in the case of an evacuation? DO NOT retrieve your hand luggage. Can you guess why? Now imagine 300 or more people all doing the one thing that is most dangerous in an evacuation. Just give it 5 seconds’ thought and you’ll see why hundreds of people retrieving and donning backpacks will kill far more people than it could ever possibly save.
If the plane was actually in danger of an imminent crash, people would be rioting and pushing others and trampling them just to get to the door. Keeping a parachute under the seat should be fairly easy to get on, but getting out would not be
This video is good at making minor inconveniences look impossible
Great video. From a licensed skydiver, I see one flaw. Yes, it takes 25 supervised jumps to get certified to be a recreational skydiver, but there are much less complicated emergency parachute rigs which may be able to be used in an emergency. For example, both George HW Bush and John McCain bailed out of their planes and without any prior parachute jumps. Still would be impractical to implement on the scale described in this video.
Solution, design commercial plane with with hatch at the back and gets certified for parachute jumps. Have a backpack w oxygen gas inside.
Are you sure, they didn't have even jumps from tower? I guess, these are not recorded. Being naval aviators, I think, they had at least some basic training. But I have another story, told by bomber pilot and former parachute instructor. How helpless he felt, while bailing out at night. And ended up with broken legs and heavy concussion. Ironically his plane landed itself safely and was repaired before crew recovered from injuries.
@@trex2621 death or broken legs, what sounds better?
@@Vanadium In these conditions either of us would have died anyway.
A few things comes to mind. In Military industry, pilots would have to jump with their own parachutes in case of being shot down. But it got replaced by seats with parachutes that shoot themselves out of the plane.
And then we have Airborne. Yes, makes sense why they are considered elite. Not only they have all this training, and have to do it in active combat zones, I remember that you need to be able to use the right landing position to avoid breaking your legs, and there's a risk of getting your parachute all messed up on itself if you let it fail the controls, plus there's the risk of it getting stuck with another person's parachute, and it can end up stuck in a tree and let you hanging there. And then again, Airborne are trained to jump out of good planes, and when it's going down like the video says, they mostly always die, either by fire or getting shoot by the AA guns, or by a failed landing or parachute.
So yeah, if even the military had to make it so pilots have a easier way to eject than to take lessons with Airborne, which normally carries about some dozens paratroopers, imagine training the millions of people who probably will fly 6 times in their lifetime.
The guy who jumped into the jet turbine was just tragically hilarious.
Thats my favorite part
4:29
Quick grab the parachute! You ready!?
"Yeah I got this! Alright I'm ready!!!"
Okay jump!
"gerani-NOOOOOOOOO!" (Splat)
"Uh... Okay next exit!"
the guy who gets split in 2 tops the list for me
Propeller guy from Titanic has nothing on him
Great video. Adding to your cost factor would be not just the size of the equipment, but even if you could get that into a seat somehow. It would bring the total empty weight of the aircraft up, needing more fuel or reducing passengers to offset.
Thinking outside the box, the commercial plane itself could have parachute-like devices to slow it down if in freefall. Those could help to reduce speed to a somewhat survivable one, in an emergency. Space capsules and some military jets already use similar devices.
correct, this should be the question everyone asking
Cirrus jets come with a chute
A parachute strong enough to hold a n airbus a320 for example would use all the storage capacity of the plane and probably be too heavy to fly anyways
@@squirrelhallowino29 It's already being done on other flying machines. You can get the same effect with several smaller parachutes placed in strategic places, like airbags in a car. It doesn't need to be heavy or bulky to be effective.
Yes i know that, but an airliner is a ginourmous fully loaded plane, there's no space for a parachute that can hold an airliner@@SevenSixTwo2012
This video editing was one of the most fun I've ever found on youtube!
Hmm strange
Thanks 😊
If a crash is inevitable, but the plane can still glide to a lower altitude and still have air brakes, are parachutes still not a good option?
@@hixta If the airplane can glide, the crash is evitable. What parachute WILL do is giving the crew an option "B) F* it, take the parachute and ditch the plane"
please step outside today.
This question has been on my mind for at least 20 years now.
Well I hope we put that one to rest? 🙂
I don't mean to be rude, but wouldn't 20 seconds of thought make it clear that putting all the passengers into chutes and getting them to jump *would never happen* ?
@@pkz420 Install a chute on the plane itself.
Great animations. I laughed through most of this and love that it’s both entertaining and very informative. Keep up the good work!😂😂
Was a skydiving instructor for 25 years and this is a great and funny video that explains why parachutes are not practical. Have been explaining this to many people over the years. Sensory overload on exit is another reason people can not be trusted to use one even if supplied.
did not mention the fact that you would need hire people to pack, check, and certify the chutes as a miss packed or faulty chute would also equal certain doom.
What's better 100% death rate with a crashed plane, or 50% with some dying on parachutes?
Idiotic take. Lots of people would gladly buy their own chutes if there were a proper way to exit. .
@@garrysekelli6776 still they would need to be checked and certified even if it was byod.
@@stewarde17 nah. It would be up to the passenger to check his own chute.
@@garrysekelli6776 sure if the airline wanted to be found liable for lawsuits
Also:
1. Parachutes only work if you are properly attached to them and for obvious reasons this should be done _before_ the emergency occurs so you'll spend an extra 15 minutes at check-in being fitted with a 5-point harness that will be digging it's way into your naughty bits for the duration of the flight. You can't even do a #2 with that thing on so diapers are probably in order.
2. Random people cannot be trusted to pull the cord when they are hurtling out of the plane at a gazillion miles an hour so they will have to be tethered to a line that pulls the cord for them. Again; no time to do that as the plan is crashing down so you have to be attached before take-off. 200-300 people. Try it.
3. Disembarkation will take minutes and during that time the plane will still be doing several hundred miles an hour so the passengers will be landing in a long string of several dozen miles of... well wherever the plane happens to be flying. If you are lucky it's water near a shoreline with lifeguards but it's most likely you'll end up in the ocean with resque several hours away. If you are unlucky you crash on the motorway and get run over, or land in a jungle and never be seen again, or get tangled in powerlines or just get hanged by a twirly landing in a tree. You may even get a short expedition on a mountaintop, hey at least you got to see snow!
4. Danger #1 in parachuting is breaking limbs when you land the wrong way and we're not talking a gently "ouch", we're talking bones sticking out. There *willI* be no ambulance waiting for you, you're just one of 200 others that have landed in the middle of nowhere so you're going to bleed out. A quick splat in the plane would be a much mode dignified way to go.
Not to mention that to empty a large and uncontrollable airliner before it hits the ground that gives you about 3 minutes to evacuate some 400 or so people. That is over 2 per second, so suffice it to say almost all of them would likely end up tangled in each others chutes. This would of cause result in improper deployment of the same and certain death. You would somehow need to co-ordinate each wave leaving from the doors of the aircraft around the same time to deploy at different altitudes to make sure they have room for their chutes not to interfere. This is simply not practical. Then again if the aircraft is so badly damaged that it is unable to make a much more survivable emergency landing it is fairly unlikely the forces involved would allow egress anyway. Trying to move around in a crowded plane where everyone is effectively weightless would be tricky enough and probably needs some additional training. Trying to do the same in the more likely scenario where you are immediately pinned to the floor, sides, ceiling, or front/rear bulkhead by a force several times your own weight would be near impossible. Especially with the injuries you would likely sustain when removing your seatbelt and immediately being flung into the above by that g-force. If the plane can't fly and land there is after all something catastrophically wrong with the aircraft flight controls so it being in the sort of unusual attitude that will cause this is likely.
I would rather be hurt, lost, and waiting for help than dead. So i will take my chances.
@@traveonramey2474if you would parachute out of a commercial plane, you would be dead even before than touching ground.
@@traveonramey2474 You'd never get out the door of the plane anyway. You're far more likely to choke and die on the cookie that you were served on the flight anyway. Flying is already miserable and expensive enough. You want to make it worse?
Highly trained and disciplined military personnel take 1 second per person per door to exit an aircraft in flight. And, that is only after they are rigged and inspected for a parachute jump.
Imagine 100 untrained and panicked people trying to rig their own parachutes and jump out of a tightly packed and cramped airplane. Half of those people couldn’t even properly put on the currently used oxygen masks during an emergency. And, all of these people would be impeding your way. How long do you think it would take the average person to exit the airplane from the start of the emergency?
If the plane was still controllable enough to execute a controlled evacuation I think I would take my chances on the emergency landing. Most aviation accidents with total loss happen so fast that there would be no time for an evacuation.
Good explanation and I like the animations. As a solution to all of this, I envision a passenger jet with a detachable passenger section. Something along the lines of the cargo plane from the old Thunderbirds kids show. I could be one big container, or split into smaller sections, with parachutes on the container and perhaps inflatable bottom to make it a life raft if it lands in water. Or, for a more technological future, the container itself could be a self-landing drone.
I dig it, but the construction of such a thing would be very heavy. It would cut into airline revenue, and we can't have that...
Parachute the plane itself with a top hatch that greatly reduce the drop speed of the craft itself
There's also the fact that a lot of air routes travel largely across vast expanses of ocean or arctic where a parachute wouldn't do you much good.
So if you manage not to:
- get chopped in half by plane parts
- get eradicated by the planes engine
- keep your lungs intact
- don't freeze to death during the jump
- remain conscious in the thin atmosphere
- manage to reach the surface safely
you're probably going to freeze to death in the cold waters of the ocean
They can show the old Air corp winter and desert type survival training films while in flight Like how to make a tent from a parachute etc
Better than crashing into ocean at mach 1. Lmao. Would take the chance any day than just dying.
sooo how about the plane having space shuttle-like parachuts then?@@KraytTheGreat
@@KraytTheGreat
So if only some rich people and corporations managed to:
-design new planes with this emergency in mind
-don't take hundreds of peoples per flight to be able to afford the ceo's monthly electricity bill
-design special parachutes easy to use
-design it in a way that it also acts as a life preserver
-make it so the equipment comes with a jacket
-make it mandatory to wear it during travel
also, surface temperature of the oceans on average is 20c
the oceans are rarely in a state like jack sparrow is going through some serious shit nearby.
I would prefer taking my chances. The alternative is watching people shit themselves in panic, crash into the ocean and drown not knowing where is the exit or where is up or down, that is obviously if I'm still alive after the crash.
5:10 hahaha those poor passengers slamming onto the fuselage had me in tears.... i feel bad now
😂
Indeed some large banging nosie there 🤔
What an incredibly well explained video. Good animation as well. Subbed!
I’m surprised you didn’t compare the average non lethal injury from an airplane crash and skydiving. Assuming the severity is similar, first responders would find you much more easily if you stick with the group. And there’s a good chance that the other passengers could provide some kind of first aid
Your videos are cool
I can see the effort and care put into the script, the visuals and research.
Not only that, but Stu is also really charismatic, and seems to enjoy what he's doing.
Keep it up!
Thank you Davi 👍
Long to put on properly, lack of training to operate and land, lack of oxygen at altitude, crowd panic, and you may simply be fairly safe trusting the pilot. Also I love the style of this channel the animation is amazing!!!
Great video, so detailed and neatly done and well explained! One minor nitpick is that when you talk about the cost you appear to be double-counting some things. For example about the oxygen apparel I thought that was being included in the earlier analysis. Aircraft design was definitely part of earlier analysis, so you can't count it twice that 1) normal aircrafts don't work and 2) it costs money to be redesigned, as they're the same point. Let's say if you count the redesigning as a money problem then you can't count it as an insurmountable physical risk like it sounded earlier. Hopefully that makes sense.
My son used to ask me the sorts of questions this channel answers. "Why is the sky blue?" "What do rockets push against?" "Who is Mandy and why did Barry Manilow send her away?"
The story of the Gimli Glider is so incredible, I will never forget that!
🤯
There is a movie about it, but I think it could do with a big budget remake 🤔
Informative and fun. Provide parachutes for commercial airlines really cost huge amount of money... And... More risky(more than 90% passengers are likely lack of knowledge in parachuting).
Very well crafted ad, good job!
@6:15 even heard the sound of the lungs going out 😂 appreciate the details in this bro, had a good laugh.
Funny, entertaining, and extremenly informative video! I also loved the smooth segue into the commercial. Well done :)
Thanks 😊
One thing you forgot: wenn people jump from great night's and with 500 mph of speed, the jumpers will be dispersed in much bigger area than it's feasible to search with helicopters or planes. Above water the chances of survival will be much less.
At that speed you practically instantly die. There are crash sites where aircraft disintegrated at great height, where the bodies they found were all without clothes and body hair. Basically scrubbed clean by the airflow during the "egress".
That seems unlikely given the tensile strength of hair and the 6 or 7 G deceleration for a couple of seconds is not unsurvivable. Flail injuries are possible, but I doubt it would remove body hair unless this is caused by entering a cloud of burning kerosene.
So you're saying crashing into land double the speed has much higher survival chance? lmao.
@@MGZetta No, I'm saying that the people are much harder to find in the sea. They are drifting away, drowning, going under, being nibbled on by sharks, etc. On land there are only animals to nibble on them. They won't move much if they are dead or wounded.
And since they jumped off by parachute, the crashing part of the plane is of no concern.
@@moranjackson7662 A complete stick of military paratroopers drowned because they were dropped 5 minutes too early and not retrieved in time. So imagine civilians.
Good breakdown. This is why it shows that u need to go depth to analyze something instead of assuming that an idea is good just cuz it sounds good.
Thank you for answering a question that was lingering in my head for so many years.
Glad to have answered it 👌 Thanks for watching and commenting 👍
I’ve brought my Skydiving Rig on a commercial flight many times(traveling to skydive elsewhere). And every time people would ask me about this. I’d explain basically everything in this video and assure them that if the plane goes down I’ll be just as dead as everyone else :) and that my Rig is about as useful as their neck pillow in an emergency… probably less so, not as soft you see ;)
😆 brilliant comment, thanks!
I've also brought mine, but when people give me funny looks, I like to say, "just in case"
just jump when the plane is about to crash

Thank you for watching and commenting 😊
Having done sky diving a few times , there are a few reasons why there wont be any Parachutes on commercial planes , first is cost would be ridiculously high not mention the chutes will need to be checked regular , two if for example the aircraft was a airbus a 380 which can hold between 400-500 passenger the panic that would ensue would be ridiculous a lot of chutes would be twisted with each other if they all jumped at the same time and may create unnecessary deaths. Not to mention that passengers would need oxygen tanks if they are to jump above 14000 ft (hypoxia above the 14000 ) so the chute would only been used at that height and below. Then there's the weight all this would add to the payload, which intern would maybe affect what passengers can carry on board . There would also need training , and what if passengers have kids ? , truth of the merry is planes are still the most safety way of transport in the world and crashes etc are rare.
I've seen that most plane crashes happen so low and within 5-20 seconds that you probably won't have time in 90% of plane crashes
If the plane is at a high enough altitude to make parachutes a lifesaving option, the plane has altitude enough to buy time to remedy the issue or choose another runway to land on.
Such a comment could only be produced by a mind with extremely low IQ
If a passenger plane is at a high enough altitude to make parachuting an option, then the cabin is pressurised and you're NOT opening the door without a small explosive.
not if youre flying over a mountain range
@@aetheriality The cool thing about mountain ranges is you can navigate away from the highest elevation.
@@syndrome5372 That's why i always bring small explosives everytime I travel

😆 thanks Melissa
So in order to successfully parachute jump from a jet liner, you not only need extensive training, but also need to have the plane fly at conditions in which it is already performing a likely very safe emergency landing at the nearest suitable runway.
Indeed 😆
This is the best reason why not have parachutes.
Why would captain order them to jump if he is landing it safely? Lmao. Why would you need licence to jump to save your life? You ain't collecting points, you're trying to save your life. Lol. If you fail, that's a fucking good try instead of those died in the plane because they don't have a licence to pull a rope. Lol.
@@MGZettaYou are a child and you don't know what you're talking about.
But what if the airliner has pilots?
They could lower the altitude to sub 14,000 feet, slow the speed down and depressurise the cabin so that the doors open?
The passengers may not have any training but if the pilots are convinced that a safe landing isn't possible then the passengers may wanna fancy their chances anyway, rather than just dying in their seats.
If they have enough control of the plane to do all of that, then they probably have enough control for an emergency landing on water or in an open field.
@@dexteradams6515That would be my thought as well.
@@dexteradams6515but the plane going below 14,000 feet will happen in absolutely every situation.
@@MrHarumakiSensei Not if it crashes on a high mountain.
@@RobertR3750 OK, you got me there!
An interesting video! Though I think with a few changes you could make it something that people would pay for. It's the illusion of safety we're talking about here. You'd just need a door that can be ejected, and procedures to get the quickly plane down below to where the oxygen is, and then all you'd need is a simple parachute per passenger. I think perhaps you're overthinking the vital need for training, in an emergency situation someone hands you a parachute it's going to be better than nothing, and you just pull the handle when you're falling and hope for the best. Assuming you can fight your way to the exit through a crowd of desperate people. Perhaps that's something people would pay extra for, to have that reassurance of potential survival in a situation that usually you're completely at it's mercy. But even then I'd still have to agree it's really rather pointless, perhaps something for you to ponder while you find yourself pinned to the back of a falling plane by extreme G-Forces. 😆
The chute could easily be designed with an automatic release so no one had to pull any handles. Biggest problem I see is getting a planeload of passengers out 4-6 doors in a reasonable amount of time. I bet 90% of them will freeze when they are in the doorway (to be then shoved out energetically by the people behind them whose trousers are starting to smolder).
I can totally see something like this being a thing if plane crashes were likely. But they're such one-in-a-million scenarios that, you know, it will always be a waste for the airlines.
It's not like seatbelts, which are necessary because car accidents do happen to people throughout their lives.
The real simple solution would be to put 4 to 6 giant parachute on the top of the plane. If you save the plane you definitively save people inside.
This one was one my favorites! Really funny and I learnt a lot 😁
What about equipping the whole plane with several parachutes like the ones for them spacecrafts
Some small planes are installed with parachute systems capable of supporting the whole aircraft in a slow and survivable descent back to Earth. In theory, it could be possible to simply scale this technology up and apply it to larger planes. Though there are critics who have some serious concerns with the feasibility of attaching parachutes to massive airliners.
@@DebunkedOfficial It's been researched. An airliner is a fragile beast, you'd need to have many attachment points, and the weight of the system would greatly inhibit passenger capacity and range. Then you'd have to slow down to a speed that would destroy the parachutes.
But airliners no longer fall out of the sky as they did in decades past, so it's moot anyway.
All Cirrus airplanes, including their little jet, have parachutes, as do many light sport and experimental aircraft.
@@DebunkedOfficial Cannot be done, because metal fatigue.
@@UncleKennysPlace thanks for the extra info 👍
@@andromaxbse6459 How does metal fatigue figure into a one-time event?
A lot of these points can easily be challenged. Speed of 500 mph and altitude of 36,000 ft is a healthy plane. One that is struggling to stay in the air is likely slower and lower. I've been trained on skydiving and they're right, about six hours is appropriate for individual jumps, but in life and death, I think most would take their chances with a parachute rather than surviving a crash. Getting people out of the plane on time would certainly be the biggest challenge and not hitting anything upon exit would be a challenge as well. However, saving a few people is better than saving zero people. Another huge challenge that they didn't mention is the terrain below. Landing a parachute in the forest or mountains could easily mean death on impact. A water landing might result in a slower more painful death than dying in a crash. I tell you what though, if I'm about to crash over Kansas, I'll take that parachute every single time!
The outside air you encounter at 1/3rd normal density and -40 °C would wick away perhaps 25 kW of heat from a smooth 30 °C surface.
Initially, the skin would be able to conduct enough heat away to satisfy this with a small difference in temperature. 100 Microns of skin could shed this heat with a 5 °C temperature gradient, dropping the skin surface to 25 °C. However, we can see that by a depth of about 1 millimeter, we can only transfer about 300 W / m^2 * Kelvin, vs about 218 for the outside air. This suggests that the skin surface temperature will drop to just over 0 °C. Frostbite to the outer surface of the skin is likely past this point.
Given the specific heat of skin is perhaps 2 kJ/liter/K, we are talking about cooling down a volume of 1.8 Liters by about 20 Kelvin on average by drawing initially 25 but decreasing to about 15 kW out of it, I would say it's fair to assume that it would take around 2 seconds for the skin to begin freezing, and perhaps 10 before the frozen layer of tissue is a millimeter in depth.
However, this is more like being attached to an airliner and left freezing and flailing in the airstream. It is not what would actually occur because as soon as you leave the plane, you would begin decelerating aggressively. The terminal velocity of a flailing human is around 60 m/s at normal air densities. It would jump to around 100 m/s at this altitude. However, you are moving 250 m/s. Meaning you would acutely decelerate at about 6.25 G. Potentially a little more because you're above critical mach number.
This would mean rapid deceleration. After a second you're moving 200 m/s and a proportionate decrease in heat transfer has occurred. Another second and you're at 170, another 150, another 130, another 115, another 105, another ~100 and now falling at an angle instead of directly forward.
At 100 m/s, the air is only capable of causing frostbite vs a layer of skin that is 5 mm thick or greater, meaning that it would likely take minutes to reach that point.
So there might be enough time to freeze the very outer keratin surface of exposed skin (which isn't an injury) but it seems highly unlikely that serious frostbite leading to necrosis would occur on exposed skin. You would have time to feel cold for a matter of seconds before falling down into warmer, denser air. As we have established that the chilled layer wouldn't even reach that deep, there's also no issue of core temperature dropping and hypothermia. You're just not exposed to the conditions long enough for anything like that to occur.
Just take the time to try and imagine how everyone felt sitting in that Jet gliding for 17 minutes with no engine noise.... 😮
There’s a pretty good mayday episode on that crash where they do interviews with some of the crew and passengers
I don’t have to imagine. I’ve been there and done that in a military transport C-141 over the Pacific Ocean. It’s not as scary as it seems. A little unnerving. But, not scary. Then again, I was a paratrooper. I was also probably still groggy from being asleep on a pallet of parachutes. Isn’t that ironic? Don’t cha think? A little too ironic, I really do think.
@@deanfowlkes No scary for someone like you who are trained, but imagine hundreds of women crying and screaming all the time
@@tiagobordin6580 - You may be right. I think it is more about the personality and less about the training. I was that way before the training. It was because of that personality that I went through the training in the first place. Heights, speed, big crowds, public speaking, etc don’t scare me. However, the things that do frighten me would probably make you laugh. 🤭
What about one giant parachute for the airplane?
Explosive bolts knock off the wings and tail and the fuselage floats gently to the ground.
Some small planes are installed with parachute systems capable of supporting the whole aircraft in a slow and survivable descent back to Earth. In theory, it could be possible to simply scale this technology up and apply it to larger planes. Though there are critics who have some serious concerns with the feasibility of attaching parachutes to massive airliners. Thanks for watching!
The thing is, the plane already has a parachute, their wings
@@DebunkedOfficial it would be a cost thing again as the weight and space required for such rare use emergency equipment would mean the cost per seat would go up massively and the check in luggage weight would probs have to decrease too
FIRE HAZARD. Are you talking about equiping explosive bolts near the wings where jet fuels are stored? And deploy a massive flammable textile?
@@aaaaaaaard9586 I'd not even considered the fire hazard as I'd rejected the idea based on cost and weight before even getting there. Jet A1 is more akin to diesel than petrol
The only solution I ever came up with that makes parachutes feasible would be a static line system hidden in the void above the passenger cabins with access points at each door.
Weight is still an issue but not as much, people get to the door, put on a harness and jump followed by their already open chute.
Of course people would just panic and it wouldn’t work because of this but this I think is the best solution should airlines ever start using them.
LMAO!!!! The people dinging off the wings I CANT 😂😂😂
One thing not mentioned is the recovery of passengers. Imagine if all 350 passengers onboard A350 or a 787 would be able to jump from a plane travelling even at 200km/h at 10000 feet, that would cover an area of small country. Good luck finding injured people from the area. Even if they jumped on land and not an ocean. And like mentioned before, if a plane can fly at 10000 feet and stable speed, that plane is capable to land and no-one has to jump.
the idea is survival...finding them later is easy...actually as per your numbers and assuming every person will take 5 seconds to jump then they will be spread in an area of 3.9km diamtre, Definitely not a small country...a busted old helicopter can find them
@@mizzorian You're assuming that all of them jumped from the same spot in the matter of seconds. Truth is, if such a case were to happen, you'd be more likely to have the first person jumping about 3 minutes & like at least 10 kilometers away from the very last guy in the plane, due to the fact that the plane is still flying at a speed comparable to an f1 car on the track, when these passengers jump. With that said, your spread would be more likely to be well above 30km in diameter, than within 3.9km.
@@FalconWindblader actually we are both wrong...I dont remember my initial calculations, but running my numbers again gave me a diametre of 98km...that is huge area
@@mizzorian I wasn't wrong. i did note that the numbers i came up with was conservative right from the start, & the actual numbers could be way bigger.
@@mizzorian Plane flying even at low speed of 300km/h, and lets say it takes 5 seconds for one passenger to exit the plane, that would be 0,4km per passenger, multiple that by 300 passengers, that would be 120km. And as we know, five seconds is never gonna happen per person, counting the winds and other factors, I'd say all 300 passengers would spread in area about the same as Slovenia.
It would also depend on the fall; I doubt passengers like on AirFrance would have the ability to get out of their seats because of the intensity of the fall. The descent would need to be steady to where the G forces would even allow them off.
I live in Finland, and I'm watching that part about the temperature just before the windchill effect thinking "Put on a jacket and stop crying... oh... right, the wind..."
The smoothest transition to an ad in the history of CZcams!
Alternative is put parachutes on the plane. Or, allow passengers with proper parachute training and qualifications to bring their own parachute, temperature suit, gas tank, and modify each passenger plane with access to a lowered back door to parachute out. But, that's a lot. Lol
Flying is the safest way to travel. Far Safer than driving and even walking.
Flying via Squirell suit roof top BASE jumping IS NOT safer bruh!
Flying is the second most safe form of travel. Only lifts are safer. (Or so I have heard)
Its very sad cars are so dangerous. They, in North america, are killing similar amounts of people to guns. Its sad we(More specifically North america), live in such a a car-centric world.
These animations are fantastic I don’t know how you did it
This is like saying, if you’re in a crowded mall and shooting starts, just stand still and don’t move, you don’t want to risk trampling others. smh 🤦🏻♂️
I think the most realistic is ejectable seats,so the passenger straps on the seat,oxygen supply is on the seat aswell,and they get ejected below the plane
Wouldn’t work, the plane would be falling faster than you at the time of ejection and you would slam into the under belly. The amount of force to eject you fast enough downward would likely snap your neck.
@@nightmarekanna2922 yeah, i dont get the downwards
Cost of an ejection seat is about $140k. That's ignoring the cost of engineering a way to install them all. We'll roll that into the cost of your ticket, not mine. Also the weight added by the ejection seats would be more than half of what the plane can carry. So I'm guessing you're the one who will take one for the team and leave your stuff behind?
@@claytonberg721not that serious lol 😂
300 ejectable seats? You'll likely die by hitting another passengers
He hasn’t even mentioned the fact that g forces probably won’t allow you to even get up from your seat when the plane is falling from the sky 😂
It depends on how it's falling, planes have wings, they don't just fall out of the sky like a rock, they usually glide.
@@norma8686 did you see the most recent Chinese airline crash?
@@Lowkeyyshorts he said "usually"
Meh. Einstein 2nd law of motion says that you are moving the same with plane. And you could stand. Sort of...
Come oguys, what happened to your imaginations?
How about it's in an uncontrollable spin (pick any direction) , pinning everything to the roof, sides or front to back...
Simply because most accidents happen at takeoff or landing when a parachute would be useless and stuff that does happen at altitude usually happens very quickly.
Not sure how the CZcams algorithm directed me to this video, possibly some sort of mind reading involved as I have wondered this many times!! Thanks for clearing it up, bit I would still take my chances with a parachute over hitting terrain at 550+mph!! 😂😂
I was never nervous about flying until I was in Europe and I flew on Roman Airlines and the first announcement from the pilot was "we who are about to die salute you"
So what happened?
LOL 🤣
Amazing video as always.
I thought that planes were designed to glide (relatively calmly) back to safety, much like Flight 143 (8:20). I want to know more about Fight 447 now (8:03).
When I got inside a glider for.the first time in my life they made me wear a sports parachute with absolutely zero training. The pilot said that if we had a mid air collision he would try to turn the glider upside down and I was to open the canopy, unbuckle myself and pull my rip cord. 😅
As it turns out, the best thing you could have in the event of an airborne emergency is the plane itself. It is the best parachute, and will protect you the most from anything and everything that could ever possibly happen to you even if it is simultaneously the thing that is failing. Its kind of interesting to know that if you are in danger of crashing, the thing that would be responsible for your death is also equally responsible for your survival, and then the pilots are there to figure out how to turn a sinking ship into a lifeboat. So when you think about it the odds of surviving an emergency are much more in your favor than you think.
Not really. In most fatal plane crashes, the main body of the plane (where the passengers are sat) ends up breaking into several pieces, with the front usually ending up getting crushed from the impact force. The tail end tends to snap away. The sudden stop in momentum alone would launch your body and face with so much force into the seat infront of you. That little waist seatbelt isn't going to do anything that a shoulder seatbelt would in a car accident.
And even if you survive all this, there's still the immediate danger of fuel leak leading to a very likely combustion explosion that would incinerate the inside and outside of the plane.
There's only but a few handful of fatal airplane crashes where the full plane body managed to stay intact. Most end up as burning, crumpled debris.
@@_Just_Another_GuyGoogle is your friend if you would use it.
"Your odds of being in an accident during a flight is one in 1.2 million, and the chance of that being fatal is one in 11 million. Comparatively, your chances of dying in a car crash are over 200,000 times higher, averaging around one in 5,000."
What people don’t understand is that skydiving requires training and practice just to get to the point of not dying. I’m a licensed recreational skydiver with 78 jumps (been jumping for a year now) the average person would spin out of control immediately before passing out and would never get to pitch their pilot chute, they’d fall to their death. The course took me 3 months to finish. Learning to balance your body on air takes practice and dedication, it’s not easy to learn and then you have to learn canopy piloting which would easily result in serious injury or death for an untrained person.
so you don't like the idea of having parachute as a last resource even it was you who's in the air plane if so fair enough
@@latiforiky8940 In a commercial jet, a parachute would be a futile effort for even someone like myself considering it’s pretty much impossible to survive exiting a comercial airliner. I jump from planes that are specifically made for skydiving which don’t present to the risk of hitting the tail of it on exit
WWII pilots bailed out of planes with no training. It's nice to have multiple hours of training, but not required when the only fucking goal is survival.
@@295Phoenix Ok know it all you have no idea what you’re talking about
@@commonsense5555 Actually, I do, dumbass. WWII pilots carried parachutes and used them without training beyond watching a video of a guy using them. Yes, alot of training is needed if you want to GUARANTEE safety but that doesn't mean an untrained individual is guaranteed to die nor does it mean that an untrained individual is better off without a parachute when their plane is going down than without it.
Airlines crunched the numbers and decided they are willing to take the risk of you not having a parachute 🤣
Very interesting, I actually had that question on my first (and so far last) flight
Glad to have answered it! Thanks for watching and commenting!
😂😂😂OMG I should not have laughed so hard at the little people plinking off the plane! I'm weak af 😭😭
Titanic. 😉
Plus, when a plane is plummeting toward the ground your are either pulling multiple Gs or are essentially weightless, making even the evacuation of a SEAL team unlikely to impossible.
there is also the issue of hindsight... in an emergency it is unlikely anyone know if they are going to die or if the pilot will eventually put the plane down safely... so if everyone just risk their lives to jump out with parachute it might end up making it more likely ppl would die (due to the various factors explained in the video) than if everyone stayed on the plane and let the pilot take the plane safely to the ground and save everyone..
unless it is clear that the kind of emergency is impossible to save like if plane itself breaks apart or the plane is falling fast and seconds away from hitting the ground in which case it is unlikely u will be able to don the parachute to survive anyway...
What about a massive parachute that opens in the tail of the plane to slow decent? The type you see deploying on space craft that splash down in the ocean?
Perfect video! How about a giant airbag system, essentially turning the entire airplane into an airbag upon impact? lol
I bet that's why they call them Boeings because they would go _Boeing Boeing Boeing_ when they hit the ground
The decceleration of your organs against your seat, or other organs, is what causes injury. If there was no kinetic resistance between organs or the body and seat, then there would be no injury. Acceleration cannot kill if there is no object resisting your body's change in inertia. Kinetic resistance between a pilot and his seat is the same as decceleration. Like falling and hitting the ground. The problem is not necessarily acceleration, rather it's rapid acceleration and rapid decceleration.
*Wrapping yourself in an airbag won’t help, it will just contain the mess.
@@Make-Asylums-Great-Again if that were true, airbags in cars would be of no benefit.
czcams.com/video/HV4JzoeaWTQ/video.html
It's called cushioning the impact. I'm not saying it would prevent 100% of injuries, but if it were possible to put a giant airbag on a plane, it's plausible that it could save lives!
@@Make-Asylums-Great-Againeven just acceleration in itself could kill you, in fact jet pilots, need to wear special suits to keep their blood flow in place during high G maneuvering.
Many of what has been discussed here can be solved easily, the high altitude problem for oxygen and temperature is really not a problem because a crashing or falling airplane eventually drops altitude intentionally or not, second fast and high-pressured air can be solved by slowing down the airplane especially if it runs out of fuel and glide, the only things needed are parachutes and a big openable section in the back, which I think is not that hard to achieve.
But don't forget: they lock the doors! There's no possible way around that issue. Completely unsolvable problem there…
That one probably bugged me more than anything else in the video. If you're gonna say "can't parachute out because they lock the doors" then you might as well say "can't parachute out because they don't give you parachutes"
They're really not exploring the hypothetical
@@douglaswolfen7820 well, open the locks first, problem solved. :)
The issue is as he said, is due to high speed and air pressure, which is not the case when the airplane slows down, especially if the door is in the back where air drag is much less and the risk of passengers hitting the airplane is zero.
In fairness, most commercial airliner crashes that have happened throughout history which killed everyone on board happened in seconds. With a lot happening on take off or landing, or because two planes crashed into each, or a sudden electrical fault, or because an idiot Russian captain decided to let his son pilot the plane.
Either way, you'll be lucky to make it to the door, let alone skydive out.
LOL! Whenever I fly I always would joke that instead of my seat cushion being a floatation device, I would rather it be a parachute. Just a joke, but now I know the reasons it’s not ever considered by the airlines. Thanks 😂
That would be pretty expensive
Although I agree that your best best is staying with the plane (the vanishing small risk that anything will happen on your flight, PLUS, the pilots are trained to make the best go of the least destructive landing). That being said, if the plane is bad off enough that it can't stay up, chances are that it's air speed HAS dropped to the 100-150 mph level. Proof of this would be apparent by watching how quickly the plane is plummeting. Many planes have status monitoring displays on the seat screens, so if the speed was low enough, you'd definitely want to make the jump.....particularly because the best pilot in the world can't keep the plane up once stall speed is reached. Also, stalled/dropping planes tend to spin (not certain, but very likely) and that would throw the skydiver clear of hull impacts...assuming he made it to a rear exit to begin with.
6:39 I guess that temperature is really just a minor issue. You normally open the parachute just when you reach 1000m above ground, where it usually already has normal tempertures (except if you are for instance in Siberia in the winter). And falling around 10km without a parachute just takes a few minutes. Some people go into a Cryotherapy chamber with much lower temperatures like -110 °C for a few minutes and even that isn't considered dangerous except if you have heart issues.
Your time of useful consciousness at airliner altitude is mere seconds. Combine that with decreased motor skills from cold shock or hypothermia, you will have bodies falling from the sky, out of control. And, putting on an adequate pressurized oxygen mask suitable for terminal velocity would be beyond the abilities of most of the passengers. Half of the passengers can’t seem to figure out how to properly put on the onboard oxygen masks.
Unstable body positions will result in canopy failures. Lack of training will result in collisions which will result in canopy failures.
@@deanfowlkes most of your points are valid but I doubt that a "cold shock' has immediate consequences on mobility. Thermal conduction is really just a slow process, so if you come out of a cabin with 20 °C into thin air with -50 °C it will not immediatly effect your mobility. It would probably take a few minutes, as in thin air it takes generally longer. So while you will feel thr freezing temperatures immediatly, you will long be unconscious before it affects your body.
@@rfvtgbzhn - While I agree with your point about it taking time for cold shock to set in, I do have another perspective. Having had a reserve parachute accidentally open at 18,000 feet, I can tell you that it takes a very long time to descend under canopy. At 18,000 feet, the air will be near freezing level in the US regardless of the time of year. At 36,000 feet, the air will be well below freezing level.
It’s gonna be a scary experience
I’ve always wondered why planes don’t have giant parachutes for the whole plane
Its simple, it would take too much space and add weight = less room for passengers and higher cost. If there is anything airlines hate its cost, got to keep the profits.
Do you realize just how big and complicated a parachute for a commercial jet would have to be? That's not something you could just plop on.
Despite the potential issues this is the only feasible solution. It takes far too long to evacuate the passengers in the event of an emergency. I believe the system could be designed so the tail would break off and parachutes would be deployed.
Simply because commercial airliners are too heavy. Aircraft parachutes do exist, but only for small aircraft.
I remember reading once that for a 747 you'd need something like dozens of parachutes, each the size of a football field, to slow the rate of descent enough for the impact to be survivable.
@@xyz__________7218no. It’s not the space and weight for the shutes. It’s that you would need to build separate pods that could have independent shoots. The logistics of building a jet and attachments for shutes are different.
Better to just make the planes not crash.
And that's not even mentioning that you have no idea/control over where you land. Might end up in an ocean, lake, desert, mountaintop, ravine... wilderness filled with dangerous animals...
Indeed!
Okay, like NO. Look at their smiles LMAO. 7:15 I couldn't take it and died when they all started to smile xD
I died laughing when the animations slammed against the plane lol
I bet when airliners get in enough trouble that jumping out looks appealing, they are no longer traveling at 400+ mph. Also, the door openings could be equipped with a wind deflector that can go out in the slipstream and allow you to start your drop straight down (with respect to the fuselage). As far as the breathing kit, there is already an oxygen mask for every seat on board, just make them removable.
So you are trying very hard to undo something like 10 years of commertial airliner aerodynamic development (needs more engine power, decrease gliding range) for barely any help during unlikely event of emergency during cruise.
How about advance aerodynamics further so during the same event plane just glides further, potentially reaching airport. Also during normal flight - save fuel so airline is profitable and can actually perform all required maintenance.
how do you like the idea of turning a 12h+ international flight into a 24h+ flight?
If the emergency happens at a high enough altitude and in a steady enough trajectory (eg. you're not being violently thrown around the cabin or sujected to extreme g forces) that you have the time and ability to rig up a parachute and removable oxygen mask and successfully evacuate, then there would more chance the plane could make a successful emergency landing giving you a much greater chance of survival. Especially compared to throwing yourself out haphazardly into air that is freezing and you cannot breathe.
Plane crashes don't always have 100% fatalities you know.
The issue with a scope like this is the slow transition from fact to opionion and slippery slope fallacy.
Here's an alternative *course of events*:
1. Skydiving/parachuting lessons could be taken *once*, before granting a person the right to fly. Similar to driving lessons. The person would then have enough experience to not need to be taught every single time he flies.
2. Flying code may be changed, to allow planes to fly closer thereby mitigating some of the issues experienced with higher altitudes, thereby reducing the need for oxygen masks and lowering cost.
3. Mass production can reduce the cost of the equipment through scale benefits. Cost is not something locked in stone.
4. Products would need to be produced *once*. It's not an expendable cost.
5. If you remove the need for oxygen, a parachute bag is likely to occupy a similar size to the expandable lifevest in present airplanes.
Flying at high altitudes is a cost saving mechanism. Reducing drag and fuel cost.
So... The "problems" of a commercial airliners still boil down to money. (And current technology).
I'm suprised why not more thought is put in *the premise* of the situation, but rather presented as *bare fact* whereas cruise altitude is a conscious cost saving choice.
What’s weird is that I’ve had this exact thought less than 2 weeks ago and now this video pops up in suggested
Wonder how expensive it would be to install trap door under every seat and have every seat installed with parachutes inside them.
Not quite the same, but ejector seats in fighter jets cost around $250,000. Thanks for watching
The installation of trap doors under each seat would increase the weight of the aircraft so much that it probably couldn't get the aircraft to leave the ground. That will insure maximum safety for sure!!!!
Spirit airlines: "Welcome aboard this flight, there are no seatbelts, air masks, or even seats. Please hold onto the bar in front of you and if you happen to hit your head please dont ruin the flight for everyone."
Everyone: *Head keeps hitting the bar*
Spirit airlines: *loses control of plane*
Everyone: "Where are our parachutes!"
Spirit airlines: "Thats only available in the platinum gold bundle. Plus they cost too much."
*everyone dies*
😂 Our equivalent is Ryan Air. I think you have to pay to use the W/C.
That ad was bloody smooth. Hat off.
The only reason is cost.
That's it, nothing else preventing it.
If a fighter jet can parachute, so can normal planes.
Every issue mentioned in the video can be fixed, as most passengers would prefer "injury" over "being dead".
✈️
Why not just have one big giant parachute that can deploy so that the plane won't fall to the ground as fast?
That's be so heavy and inefficient, Ticket costs would skyrocket by about 120%.
Heavy, needs to be made to suit the heaviest of passengers, not enough time to deploy, parachute malfunction, parachute cost, plane can snap, plane not be able to be used again most likely, more expensive ticket and many more
You can go lower and reduce the speed also just use basic skydiving techniques to avoid hitting parts of the plane. The hardest part is the orderly evacuation and having enough time for everyone.
I'm sure that would always be possible after a plane suffers a catastrophic failure. Good thinking.
@@shane7133 Honestly, if that was possible, it seems like the plane can still fly well enough to land as well.
Highly trained and disciplined military personnel take 1 second per person per door to exit an aircraft in flight. And, that is only after they are rigged and inspected for a parachute jump.
Imagine 100 untrained and panicked people trying to rig their own parachutes and jump out of a tightly packed and cramped airplane. Half of those people couldn’t even properly put on the currently used oxygen masks during an emergency. And, all of these people would be impeding your way. How long do you think it would take the average person to exit the airplane from the start of the emergency?
@@deanfowlkes So half of them die trying to jump versus all of them die trying to complain how stupid the parachute is. Lmao. Yall are hilarious.
@@MGZetta - Seeing how people act in an emergency, I doubt even half of them would make it out of the aircraft. It would just be a cluster gaggle of people trying to get rigged up into their harnesses, prematurely deployed canopies, hung jumpers at the doorway, people freezing in the doorway, etc. Just look at how many people can’t follow the simple instruction of leave your carryon baggage when having to evacuate using the emergency slides.
The very few who actually made it out of the aircraft would be killing themselves in piss-poor landings and killing others in midair collisions.
Then, there is the potential risk of having untrained individuals get access to parachutes on an aircraft. One prematurely deployed canopy could block access and freedom of movement in the cabin. And, you could not imagine the absolute carnage that will happen if a prematurely deployed canopy makes it out of the aircraft.
The only reasonable possible solution that I have seen so far is to divide the cabin into smaller sections that can be deployed individually in an emergency. The technology is just not there yet.
Well I jumped solo after just three hours of instruction strapped to a basic army chute in 71. Wouldn't advise it now of course as I nearly came unstuck on my third jump due to inadequate training.
You have a parachute:
Wanna leave the plane but it's too high?... I got you, wait till 13K feet then jump
There's no rightly positioned door? I got you, tell the pilot to drop the plane tyres, then go from there
Wind pressure too much? I got you, become a spear🗿
As long as the crash doesn't happen below 1K feet and you have a parachute there's a solution
Now do the video showing why you can't jump from a helicopter right before it crashes and survive.
That's actually one I've been thinking of doing 😉
