  • '... has some explosives left over. so decides what happens with a really big bang' I love you mythbusters!

  • The explosive did most of the damage! This was not a proper experiment.

  • The only thing they left out and would have to be tested is, Well that plane is standing still and not traveling at a cruising speed of 300+ knots. I Guarantee you their Findings would change drastically on a plane that they had turned into a drone and did their test(s) at actual altitude and speed. .

  • hmmmm yeh this is really bad its at ground lvl

    

  • Yeah thanks for teaching terrorist how to do it!

  • @marioo360

    you're a smart one aren't you ?

  • Too many factors not accounted for????

    43 people need to search google for "OUT-FLOW VALVES"

  • there not 38000 feet in the air

  • @venter234

    Thats why they pressurized the airplane to simulate being at 10,000 meters or 33,000 feet.

  • Apparently terrorists don't watch this show

  • BUSTER MADE IT <3

  • time to see what happens with a big hole huh? : 3

  • Ballowall: The narration explicitly states that the pressure differential between the inside of the craft and the outside is the same as would exist with a pressurized (to ~0.75-1 atm) aircraft flying at 10,000 m (32,800 ft).

  • you also have to take into account the lower air pressure high in the air.

  • There have actually been cases where people were sucked out because of decompression.

  • in 850 km/h the suction that happens in the small spot in a window can be really enormous and has no relation to the try of this video.Also the differential pressure between 1 bar pressure in the aircraft and less in 33000 feet level flight is really much bigger than lets say 1.8 bar in the video and 1 outside.suction to pressure near zero is much huger!!

  • I would also like to point out, that most aircraft are pressurized for 100 or 200 feet above the altitude they take off from. So if you have the same atmospheric pressure inside as you do on the ground.. of course nothing will happen. Try it with a plane pressurized at 500 feet flying at 30,000 feet at 500 mph. Tell me there would not be an explosive decompression.

  • They didn't test this from altitude, nor moving. Pressurizing an aircraft at sea level is useless. Seriously discovery channel? Don't you have enough money to potentially trash a dc-9?

  • @Kopihucky. Here here! Whoever thought that what their doing is acurate and questions the belief that what we see in the movies is real, got an "F" in aeronauticts! lol! At 30,000 feet, even the most smallest hole, like the gun bullet hole, can cause decompression. All it takes is just one tiny hole, which can become bigger depending on location, for it to cause decompression.

    These guys just forgot that you need outside pressure for it to work. And a huge hole made by bombs does not prove it

  • @DeltaEagle7700 A hole causes decompression, not immediate explosive decompression, which was the myth being tested. The recent american SWA emergency landings after flying ~150 miles with a 5 foot hole in their passenger cabin roof is the latest example.

    The myth was about making the plane instantly explode by poking a small hole in it, leaking some pressure. I also find it funny that you had to say "no really, a hole in the plane will cause it to lose some pressure" as if it weren't obvious.

  • A DC10 went down near Paris in the '70s. The rear cargo door failed. Then, basically the floor of the plane and all the passengers went out that cargo door! Turned the aircraft inside out!

  • Being sucked from a bullet hole I've only seen in Alien Resurrection (4), and on a spaceship... in the vaccum. Slurp... Sounds more like it.

  • It actually does decompress... Ever heard of Air Crash Investigation Hanging by a Thread?

  • Wouldn't the suction created by air moving at several hundred miles per hour be more of an issue then the decmpression? Plus this should have had a live pig in there.

  • @OliverKrystal They already tested that, its negligible.

  • @OliverKrystal you hit the nail on the head..... the decompression, coupled with the suction from the speeding wind outside the plan, would create an enormous vacuum.

  • The fact that a plane is flying, the fact that its flying at 30,000 feet, the fact that its flying at cruising speed, the fact that the interior is pressurized, account for the enormous pressure difference that will explain 'explosive decompression'.

    UNBUSTED

  • @DracoRenaissance They already tested that.

  • there hearing is gonna go in couple of years

  • @superpwnageguy they are using ear protectors idiot.

  • @MrAzzman31 They only help reduce the noise not fully protect the ear.

  • I am very, very sorry, but there is one BIG problem with your experiment: You conducted it ON THE GROUND. Rig the plane up to fly by remote control, take it up to 30,000 feet, AND THEN try it!

  • hahaha "small holes ain't gonna do it. So now its time to see what happens with a big hole...he...hee.hee..."

  • buster at 3:54:

    "Man, y'all need to stop fuckin' playin', for real!"

    in a deep black man voice.

  • all of sudden everyone becomes an expert lol

  • @sundoghrs Yeah I love how people who probably really have no idea about this stuff, sit and criticize guys who have been tinkering professionally most of their lives and know alot more then most can know.

  • ????? was this aired in the US?

  • ehm the explossion blew the plain up , damn so shitty these lads must feel like apes. fucksake

  • @TedFnBuckle nah, they did exactly what they set out to do. Speaking of apes, you type and spell like an untrained ape. Maybe you should worry more about your own shortcomings before you bad mouth others? Just a thought.

  • @zeppelin67637 Relax , i aint judging them in person, is shit what they did, and this aint english class i type how ii like mistakes or not, i type faster than i think. cool or wha.

  • what happens when there is nothing left to suck, this is when decompresion takes effect, you cant replicated that on ground becuase u dont have consistant vacum on out side of plain damn i love my spellings jaysus whjat donkeys do we have on this planet, plus one other thing the air is so thin ouside a plane 50-60 thousand feet, there for plain is like a balloon, fat heavy air burtsting into light air is easier to break plain apart, my god should i have been a nasa enginere.

  • @TedFnBuckle jetliners definitely do not fly at 50-60 thousand feet

  • of the HUGE pressure differential between the cabin pressure and the extremely low exterior pressures. By testing at sea level on a stationary plane proves nothing! they may as well taken a spoon scooped up ice cream with it and concluded....yup this made Rosie O'Donnell fat!

  • @Slider10218 you may of noticed they took sea level into account by pressurising the plane much further than it normally would be, so as to simulate difference in pressures at 10km,  i do admit tempreture and velocity would have effect but they did note pressure difference

  • this is total bullshit first off you cant preasurize the cabin i dont care what you use on the interior with the aft door down and second we explosive decomp happens the are at cruising altitude which ranges between 18000 and 36000 which have an amazingly different preasure factor than sea level in some airplane graveyard. You have the -18 Celsius or lower temps at five to six miles up plus the 400-550 cruise speeds which create an even lower pressure out side the plane! it explodes because

  • Comment removed

  • try opening a door at 10000 meters.

  • Try C4!

    FOR SCIENCE!

  • u have to count the speed of the plane it has to affect too right?

  • A DC10 went down outside Paris when the rear cargo door failed. Basically, the floor of the aeroplane exited out this door turning the plane inside out!

  • Haha, thats the old Hawaiian Airlines xD

  • Is the pressure DIFFERENCE really enough for the test, or would the plane materials behave differently at a different set of pressures with the same differnece?

  • the 1 main factor wasn't accounted for and that's that they weren't at 30k feet.

  • I find this show entertaining, however there are certain myths where I am left scratching my head and can't help to feel that they did not account for separate variables. The airplane flying in the air with 300+ Mph of wind moving across its exterior creates a very low pressure on the outside of the plane. The air inside ( no velocity) hasmuch higher pressure than the high velocity air just outside the window(bernoulli's principle). They missed this, and the 300mph wind pushing on the damage

  • problem with this test is..... part of the damage is caused by explosives so it's hard to really tell what truly was damaged from explosive decompression alone.

  • 1:34-1:39 That's what she said.

  • Grandpa Boyd calmly explains, like you asked him what kind of fish he caught this morning, "This is a hundred-grain shaped charge that is designed to take the side out of this airplane."

  • @Deathrape2001 Sounds as though it's a London accent. So, they must have an American accent for it to match? What about English and American actors in the same movie? I know ... STOOPID, right?

  • @forevercomputing U R a troll & don't believe a word U R saying.

  • Speed doesn't interfere with explosive decompression in any meaningful way. Furthermore, though the test was made at sea level, if you pay attention you'll see that the pressure differential is the same (the aircraft is overpressurized).

  • The plane is at sea level . Is not a real esenario.  Preasure outside most be much lower. Plus speed??!!!

  • Yeah, well they can't really do it on a real plane, so they work with what they got. This show is mainly for entertainment purposes. I do agree though, there are usually variables they don't account for, but then again, you gotta figure it's kinda hard to keep account for everything with limited resources.

  • i hate the person that's doing the voice thing..

    it's like the guy from brainiac.. hate that show

  • @iTzMist it's called a narator

  • Indeed, I like the new guy better. I don't know Brainiac, but I bet we would be of same mind.

  • I don't understand this...

    The explosiveness of the de-pressuring would only occur if the plane was going at a high speed through the fabrics of the air, such as when it was in the air and flying through it. A plane sitting on the ground, not going and sitting in one layer of the air, would have the pressure comparable to you standing at a level altitude watching a plane with its engine on, wearing a blue, heavy-duty earmuffs

  • Breaking every bone to make you skinny enough.

  • I remember that is was in Hawaii, the top of the plane ripped off due to metal fatigue. if the plane was in the air at 10,000 meters it would be doing like 400 knots, out the window you go whether you like it or not.

  • People have to understand that this is a TV show. No one is going to base a new product on something Mythbusters have confirmed or busted. Stop getting so technical

  • lol don't be silly.They're not allowed to masturbate. they'd burn in hell.

  • @SingHouse What an odd thing to say. Presuming that your version of "terrorist" is now what select people want from you from a particular event early this century. My version of labelling someone a "terrorist" is the same that is detailed in the dictionary pre 2000.

  • @forevercomputing Cut the krap, clown. All the Earth knows 'terrorist' is just code 4 'N E 1 who doesn't lick the poo from jew azz". But of coruse, since everybody in the UK has their tongue so far up their himey rectums, of course U deny it's true =))

  • @Deathrape2001 Let me know when you finished growing up....

  • @forevercomputing Everythign I say is true & U know it. Go on with your 'kill-the-messenger' nonsense. Enjoy your trolling.

  • @SingHouse that made my day man!

  • That single bullet hole is all good and well if barney Fife is in charge of training hijackers until the end of the world. Shouild have done it all in a wind tunnel. Mythbusters is normally pretty cool. This one seems halfish.

  • Explosive decompression should happen at that height. There was a case (Hawaii) of major fuselage damage when one panel started to peel on the roof. It held as a small crack, then sucked an air stewardess out. She was stuck in the crack for a while but her weight combined with the pressure from within and outside the cabin sucked her and part of the fuselage away. It just took off so it wasn't very high ergo this couldn't happen but you could imagine what circumstances you'll need for explosion.

  • I agree with most people here that the experiment is not very well controlled. At Mach 0.8 at 37-40,000ft, the outside air pressure will be CONSTANTLY lower than inside. In this experiment the pressure is allowed to equilize very fast which would not happen in reality.

  • @Neutrinoghost if the pressure doesn't equalize fast, then you don't have explosive decompression do you.

  • I see your point, but in reality, the force of the explosion would be greater than demonstrated.

  • I like Mythbusters and all but sometimes they are just plain wrong. They didnt account for the fact that planes are traveling at really high speeds, and the outside pressure at 30000 feet.

    These are key factors they shouldnt miss.

  • this experiment is EPIC FAIL

    they forgot that the plane is flying like 350MPH+ and there is WIND and with that kind of wind speed it will suck you out

  • Too many factors were not accounted for!

  • true

  • 9 out of 10 times they miss huge factors which is annoying but the show is still fun and it is still just a TV show , not a Boeing/etc experiment.

  • @CooCurrent such as?

  • @spiderchocolat3 Well you gotta think when flying several hundred miles an hour, the air pressure could change more dramatically because of the airflow over the whole could act as a suction device like a perfume bottle for example. sucking the interior air out faster then just the air pressure difference.

  • @CooCurrent Like?

  • What they fail to test is whether it would be different at 35,000 feet with significantly lower outside air pressure...

  • somehow i dnt really agree with this experiment. i think buddy got sucked out cus of the rapid amount of air pushed out the window by the explosive. not by cabin pressure. a better way to experiment this would be to simply open the window instead of blowing it off. then we know for SURE that the only contributing factor is the cabin pressure alone.

  • your wrong

  • elaborate

  • the blast is between the window and person the blast would throw them away from the hole

  • With explosive decompression, you're not so much sucked out as pushed out from the pressure.

    But I don't think you're right anyway, although it is an interesting concept!

  • ok let me try and be a bit clearer.. when there's an explosion, gases expand so rapidly that it ends up creating a vacuum. and where there's a vacuum, shit gets sucked in..to add to this, since the cabin is pressurized anyway, most of the gases from the explosion will expand towards the outside. this will give a direction to the vacuum as well. so wht i'm sayin is, in addition to the cabin pressure, there was a vac. ouside the cabin which further caused buddy to get sucked out. To be contd.

  • but that is just a gut feeling.. i could be wrong. BUT i stil think they should've just popped open the window without blowing it off. the explosion obviously added unnecessary variables to the equation.

  • Wouldn't the biggest danger be the combination of speed/altitude/pressure? With the speed destroying even more of the window until the decompression becomes very rapid.

  • now time to see what happens with a big hole LOL!

  • i dun like the commentators voice in this one

  • Same here. I think this is for the British version. Just different commentary.

  • Extra!!!:))))

  • iwanOtOsmith,go study some physics.You are talking total crap.Maybe you forgot to take your medication.

  • here are a few experiments. to show that the pressure drops inside the plane when going up.

    1)buy a packet of crisps and look at it at the high altitude, it will be bulging sudgesting that the pressure in the packet is higher than in the plane,

    2)get a half empty bottle of STILL water, when at high altitude it will be bulging and when you open it it will fizz, once opened, close it again untill you land. The increased pressure will hav crushed the bottle,

  • maybe you should study physics at the university of these nuts

  • I am currently studying A-level physics, and reeived a A in my As exams. My marks were 87%, 92%,100% in my two exams and practicals. I hope to study physics/Natural sciences at Cambidge university with Nottingham being my second choice.

    I know what i'm talking about thank you very much,

    Maybe you should become more open minded and be prepared to accept that you can be wrong, a important quality for a physicist to have

  • An important quality for a physicist to have.

  • The main flaw in the test is conducting it on the ground. A different pressure of 8 psi at sea level means that the inside pressure is just 54% higher than the outside pressure—but at 35,000 feet, the inside pressure would be 3.3 times that of the outside, which is nearly 7 times more than the ratio in the test.

  • Yeah but it was the best way to test the myth, if they blew a small hole the whole plane might fall down down there is no more plane to test on! :D Unless they are rick enough to afford another to test on,

  • this is one of my favorite mythbusters episodes.

  • i agree with alot of what people are saying, the speed of the plane + its altitude would be major contributing factors.

  • Wait. Wouldn't the air pressure around the plane when it is at 30,000 feet be less than that at sea level therefore increaseing the effects from rapid depressurization? They eould have to super pressurize the cain to get the sae results at sea level

  • When airplanes say they pressurise a plane they actually remove air from the plane, lowering the air preassure, so at sea level the pressure in the plane is lower that outside(so if a window was blown it would suck inwards).

    This is better for the plane at high altidues because the pressure difference is lower (when compared to sea level vs altitude level) and building and maintaining the plain is a cheaper process.

  • iwan0t0smith if they removed air, you would suffocate

  • yes, if they removed all the air,

    they only remove enough to make the pressure difference much less noticable between the outside if the plane and the inside. this is much less that the amount needed to suffocate, or even make you short of breath

  • you have to be fake....no one is that dumb

  • Who are you calling dumb.

    here are a few experiments. to show that the pressure drops inside the plane when going up.

    1)buy a packet of crisps and look at it at the high altitude, it will be bulging sudgesting that the pressure in the packet is higher than in the plane,

    2)get a half empty bottle of STILL water, when at high altitude it will be bulging and when you open it it will fizz, once opened, close it again untill you land. The increased pressure will hav crushed the bottle,

  • you can't bring water in planes anymore :(

  • Nice try, but what you're talking about is de-pressurization, which is useless. It is okay if something is pressurized as long as it's system is closed, like the human body.

    btw, here is definition for you:

    Cabin pressurization is the active pumping of compressed air into an aircraft cabin when flying at altitude to maintain a safe and comfortable environment for crew and passengers in the low outside atmospheric pressure.

  • well speed would be a factor.....air rushing over a hole causes a vacuum effect....

  • i think the plane scene was prom a final desination movie.......?

  • The only thing missing from this test is the airspeed of flight. The air traveling over the plane during flight would work like an airbrush, sucking what ever it can out.

  • not to be a critic or anything but how can they afford to blow of the side of an airplane

  • Airplane Graveyard.

  • it was a airplane that wouldent fly anymore

  • Myth BU-

  • I doubt speed would be a factor, moreover than the fact that a small whole would still be there, even at 10k feet whilst flying.

  • i think they missed two critical factors

    1. Altitude

    2. Speed of the aircraft

  • Well, they did their best to match the characteristics of the altitude by pressurizing the plane to the appropriate level, but I guess the speed of the aircraft is important to take into consideration.

  • If you watch the full episode you'll see that they're covering that by using both a vaccum on the outside along with an oxygen unbalance to reinact the Altitude outcome.

  • if you watched the whole episode

    ull see that they pressurized the plane much like in flight

  • They compensated for altitude with the air pressure, but speed would be an interesting factor.

  • altitude was copied by the air pressure with the compression thats what they were testing. speed of the aircraft wouldnt do much it would just make the pieces fly further.

  • The compensated the altitude by increasing the pressurization of the cabin.

  • Speed would be interesting, but I don't think it's that much of an important factor.

  • (as mentioned before) All factors wasn't included so they couldn't have a definitive answer. But its a television show, right?

  • how long did it take to pressurize the plane... at 10,000 ft that time would be instant... right?

  • He says 10,000 m though. so it's around 32,000 ft.

  • they didn't test the effect of the denser flowing stream of air moving at 900km/hr surrounding the plane's exterior. that might have created a suction bigger then just depressurization from the plane's cabin.

  • interesting thought...

  • Are you saying that the air in 10k feet up is denser than the one down here?

  • no, the air has to flow around the plane when the plane is going through it. this creates a layer of denser air around the plane's outer surface. this layer of air is denser than air say 100m away from the plane. although it's possible this layer may be more dense than air at sea level, how dense it is depends on several factors like speed and shape of the plane.

  • interesting but wouldn't that denser air be present just in the nose cone for example, or wings Leading edge? or does it holds for the entire wetted area?

  • It has happened before, the entire roof of a 737 had torn off in flight before during an explosive decompression. one person was blown out in the event but the plane managed to make a landing somehow.

    I don't think depressurization in itself is enough to cause a hull-loss event in most cases, though it is still a very serious event.

  • you are talking about Aloha airlines flight 243. That decompression was caused by hairline fractures in the platings where the rivets met the door. salt water vapuors (being in Hawaii) eroded the epoxy holding the plates together. that wasnt because of a hole in the wall or window. explosive decomp usually happens because of a tear not a clean shot.

  • ah :P after i saw a plane horror, i allways used to check for small holes when i entered a plane ^^ ive traveled ALOT with planes hehe

  • I think there's something they're not taking into account, and it's the Venturi effect. Besides the pressure difference (non-altitude-related), the high velocity of the air outside the aircraft creates a vacuum inside of it. It's the same principle old atomizers use.

    I wouldn't take this experiment as a valid one.

  • Suppose they did forget about it, let's do the math. Dynamic pressure = ½rV². At about 10km, r = 0.4, so at 900km/h, the dynamic pressure difference is 125hPa. The static pressure difference will be much larger than that, so it won't change the result much. Plus, most airliners' air pressure regulator valves can compensate for up to a window-sized hole because they're about the size of a window. The much smaller bullet hole will do absolutely nothing when Hollywood physics aren't involved.

  • I just have one doubt, if they succeeded proving that a hand gun can cause decompression explosion, would the securit authorities allowd them to put the video in the air?

  • Explosive Decompression will only occour at altitudes over 10k feet with today's commercial aircraft.

  • Who let them test these things on planes? Must have been a plane junkyard of sorts where they tried this?

  • They dod it wrong. They only pressurisized inside of cabin, but outside had normal sea level air level, so they should have putted plane in big hall and pressurisize it also in sky air level. And there has been explosive decompressions in modern day, so that myth is true

  • Well, it seemed more practical to do it the way they did it. Even if they had gone with your suggestion, the result would have turned out the same anyways. However, the one factor they may have not included was velocity.

  • Absolute pressure doesn't really matter, the pressure difference between inside the plane and outside is the important thing for this experiment.

  • it will not have an effect cause they are not on a high altitude.

  • they also set the pressure inside the plane such that the plane is like flying at high altitude...

  • 2:53 red converse hehe thats awesome

  • what country is this video from, ist a different narrator

  • it's their old narrator; not a guy from a different country.

  • funny, here in europe we have this narrator. at least in finland.

  • yeah in malta too

  • Not with that pressure. But in space you may be more fucked with the small hole. (According to NASA, if you keep your mouth open and dry, you can survive more than half a minute in open space.)

  • could you imagine how much it would suck to be in outer space for more than 30 seconds? you would look like the marshmellos we put in vaccuums in science class lol

  • Open space? You mean, outside of a ship/suit? Because it's only slightly warmer than absolute zero, so there is no way in hell you will live more than three seconds. Or, I might have misunderstood. Either way, cool myth.

  • thats wrong, absolute zero is wayyyyyyy too cold in our solar system. outer space isnt even close to absolute zero

  • Absolute zero is -459 Fahrenheit (roughly) Outer space is measured to be around -454. Pretty close.

  • Space is definitely cold. But there's also no atmosphere to conduct heat away from you. The only cooling in space is radiative, and while you'd freeze in very short order (and only on the point of contact) by touching a hull in space, you'd suffocate long before you froze. On the bright side, seeing as you can't actually hold your breath in a vaccuum, you'd be unconscious in pretty short order and wouldn't have to endure the pain of massive bruising and expanding eardrums for long.

  • This a very cool video, in the experiment itself doesn't wind speed and or plane velocity play factor in it as well. Just curious.

  • wind speed has no effect whatsoever in cabin pressure.
