In (Real World) ExplosiveDecompression, if a pressure vessel's structure were to be compromised, all of the gas held inside would rush out until a state of equilibrium has been achieved (if this pressure vessel were in space, this would effectively mean all the gas would be blown out). Keep in mind that there's only 14psi between 1 atmosphere and vacuum. It would take a very large hole to produce actual explosive decompression. Consider an automobile tire at twice that pressure differential; if it gets a hole in it, the air leaks out. It does ''not'' explosively decompress unless the structure of the tire fails completely (e.g. if it is overheated).

Not so in soft science fiction. If explosive decompression were to occur, a constant wind will appear and attempt to blow the entire contents of the room out into space, and will only cease once the hole has been closed. This may even occur for several minutes, even if in real life the hole is big enough to allow all air to escape in a matter of seconds. Another common variation is for the wind to be just strong enough to make people's clothes flutter but just weak enough not to actually blow them over -- unless they have the unfortunate chance of being the [[DisneyVillainDeath bad guy]] or a RedShirt, that is.

However, sometimes this trope is justified. If the enclosed space is relatively large while the hole is comparatively small, it can take hours until the air becomes too thin for people on board to stay conscious. Even a hole that looks quite big in a relatively small space could allow anyone inside to savely leave the area or attempt to fix the damage [[ over the next couple of minutes]].

The "remaining air" fact is also neglected in sci-fi. As the air leaks out, the air pressure inside decreases. The inside should become increasingly impossible for a human to operate in ''long'' before all the air is out.

Often occurs when somebody or something is ThrownOutTheAirlock.



[[folder:Anime and Manga]]
* The Franchise/{{Gundam}} franchise uses this a lot. Sometimes it's justified (an Island 3 space colony holds around 1,600 ''cubic kilometers'' of air), and sometimes it's less so (''Anime/MobileSuitGundamThe08thMSTeam'' has a room in a ''Magellan''-class battleship decompressing for a ridiculous amount of time).
** Usually, the really worrisome holes in colonies are caused by mobile suits' nuclear reactors exploding[[note]]as seen in the first episodes of ''Anime/MobileSuitGundam'' and ''[[Anime/MobileSuitGundamUnicorn Gundam Unicorn]]'', with Amuro slicing a Zaku in half and Marida blasting a Jegan with her funnels respectively[[/note]]; some later machines use an adhesive spray to seal up smaller holes, and in ''[[Anime/MobileSuitGundamF91 Gundam F91]]'' the bad guys have developed a weapon specifically to avoid causing a reactor detonation.

[[folder:Fan Works]]
* During a segment of ''Fanfic/LegacyOfChRihan'' set in the aftermath of the Hobus supernova, a massive hull breach opens on the bridge of the IRW ''Albintian'' and the communications officer is sucked out before the emergency force fields can engage.
** Blown out. EXplosive decompression.
* In ''[[FanFic/SovereignGFCOrigins Origins]]'', a ''MassEffect''[=/=]''StarWars''[[spoiler:[=/=]''[=Borderlands=]''[=/=]''[=Halo=]'']] MassiveMultiplayerCrossover, ''Normandy SR-2.5'' suffers an airlock breach from outside. Mass effect fields kick in and there's only a slight movement of air prior to that, averting the trope entirely.

[[folder:Film - Animated]]
* Averted in ''WesternAnimation/PenguinsOfMadagascar''; the penguins puncture holes in several passenger airplanes, but there's none of Hollywood's usual continuous-wind-blows-everything-out-of-the-fuselage involved.
* When Catwoman is ThrownOutTheAirlock in ''WesternAnimation/BatmanReturnOfTheCapedCrusaders'', the air continues to rush out for long after it should have ended.

[[folder:Film - Live Action]]
* ''Film/StarTrekNemesis'', when the Enterprise's bridge is blown open.
* A running theme in the ''Franchise/{{Alien}}'' Franchise:
** ''Film/{{Alien}}'' and ''Film/{{Aliens}}'' feature this during the final ThrownOutTheAirlock scenes. ''Aliens'' has the more dramatic touch where a little girl is about to be blown out of the spaceship, but Bishop manages to [[TakeMyHand grab onto her]].
** In ''Film/AlienResurrection'', the monster is not simply shoved bodily out of an airlock, but blown into the vacuum of space through a small broken port window. It was not pretty.
* Naturally, ''Film/GalaxyQuest'' ''had'' to have this trope.
** Strangely enough, it was ALMOST justified: the living quarters were being decompressed as a form of torture. The wind actually died down as the pressure started dropping too low, although it was going too slowly to cause THAT much wind, and didn't kick up again until they broke the seal into the still-pressurized hallway.
** There's also the part where the rock monster trashed a pack of the bad guys and ended it with busting clear through the wall of the ship; you see an external shot with a bunch of stuff flying off after them but no sign of that particular hallway afterward, so it's hard to tell if it's subverted or played straight.
** Downplayed during the ThrownOutTheAirlock scene.
* ''Film/{{Goldfinger}}'' uses a variant of this trope, where incredibly big people are blown out of an incredibly small hole.
** It may be actually possible to perform this, as [[ this video]] of a crab being sucked entirely through a hole many times smaller than itself demonstrates. Also related, the Series/{{MythBusters}} [[ squeezing a meat dummy into a diver helmet]] merely by removing its internal air pressure. Scary, scary stuff that may provide a basis for this in reality, though movies are frequently known to exaggerate those well beyond realism.
** In the original novel for ''Literature/{{Goldfinger}}'', Literature/JamesBond deliberately caused it (while in the film it is an accident), supposedly having been inspired by a real-life event.
* During a DreamSequence in ''Film/{{Apollo 13}}'', the door on the capsule opens during transit to the moon. The astronauts cling to the capsule against the wind for much longer than it would take to let all of the air out. (But then, it was a [[NightmareDreams nightmare]]).
* A pressure dome on Mars breaks in the original ''Film/TotalRecall1990'' and the resulting storm is enough to pick people up and fling them through the hole. Even Arnold Schwarzenegger has to cling to a railing as if he was inside a tornado.
** Although that includes air rushing from other parts of the large interconnected colony, not a single room.
* An inversion and aversion can be found in ''Film/TheAbyss''. When an entire windshield of a minisub at the bottom of the ocean cracks as it uncontrollably descends into the [[TitleDrop abyss]] it implodes immediately. When there is a small crack in the hull of another minisub at its normal operating depth, it slowly fills with water, albeit higher than the level of the crack.
** It continues filling to a higher level than the crack because it won't stop filling until the air left inside the sub is at the same pressure as the water -- i.e., a few hundred atmospheres.
*** But the air is already at the same pressure as the seawater outside--the drilling rig is under the same high pressure, hence the use of the "moon pool" for coming and going. It's why Lindsey and the soldiers took eight hours to equalize pressure before leaving the sub.
** Realistic in the case of the glass as the cracks grow until the glass becomes weak enough to fail catastrophically as it is resisting an incompressible fluid while containing one that is very compressible.
* After Crow breaches the hull in the pre-movie segment of ''Series/MysteryScienceTheater3000'' TheMovie, the entire room starts uncontrollably decompressing until Tom Servo is blown against the hole - and is just wide enough to plug it up, as it so happens. Immediately after, Mike pulls him out and casually puts Crow's WWI helmet over the hole.
* ''Film/SnakesOnAPlane'': When [[Creator/SamuelLJackson Agent Flynn]] shoots out a window, the compression is powerful enough to destroy part of the wall, and lasts long enough to suck every single snake out of the plane.
* The sci-fi BMovie ''Film/MissileToTheMoon'' ends with the LadyLand society being destroyed this way.
* Played realistically in ''Film/{{Gravity}}''. An astronaut has to open an airlock quickly to take shelter from an oncoming [[FlechetteStorm cloud of space debris]]; the hatch slams open from the sudden outrush of air, nearly breaking her grip on the handle.
* Played somewhat realistically in ''Film/MissionToMars''. The ship is holed by a shower of micro-meteoroids causing the ship to decompress. The holes are small enough that the wind currents produced are subtle and it takes several minutes for the atmosphere inside to become too thin to breathe. In any case, one of the astronauts quickly and methodically goes from breach to breach sealing the holes so the rest of their air doesn't escape.
* ''Film/WorldWarZ'' has a scene where a grenade is set off in an airplane, during an outbreak of zombies so it really was the best idea at the time, the resulting hole manages to blow out everybody but the two characters that threw the grenade and strapped in. The plane crashes as a result of this, but the film does at least show one of the engines was damaged in the explosion.
* In ''Film/RevengeOfTheSith'', General Grievous deliberately shatters a window on his ship to escape from Obi-Wan and Anakin. The Jedi are left clinging for life until some emergency shutters activate, while Grievous (whose life support suit lets him breathe in space) uses a GrapplingHookPistol to climb the outer hull.
* ''Film/{{Airport}}'' is probably the TropeCodifier, at least for its use in films. When the mentally unhinged passenger sets off his suitcase bomb in the aircraft bathroom and blows a hole in the side of the of the jet, the decompression is severe enough to suck him out the hole and, and wreak havoc the whole length of the passenger compartment. (It even blows the bathroom door ''out'' into the walkway.) ([[ You can see it here, starting at about 1:25]].)

* Played quite realistically in the Creator/RobertAHeinlein book ''Literature/FarmerInTheSky''. During the trip to Ganymede, a bit of space junk penetrates the hull of the ''Mayflower'' in the dorm compartment where the protagonist and twenty other boys happen to be staying. The hole is explicitly only the size of his fist, and after the automatic failsafes seal off the compartment (locking the boys into the decompressing room), he's able to plug it with one of their foam-rubber pillows.
* In ''[[RepairmanJack Conspiracies]]'', a gateway into another dimension opens up in a basement and starts sucking in everything around it, air included. The effects are portrayed realistically, right up to a character shackled near the gateway feeling his eardrums suffer as the air pressure drops, then recover when the windows break and new air is drawn into the cellar.
* Usually played realistically in the ''Franchise/StarWarsExpandedUniverse''. The atmosphere leaves a little craft pretty much instantly. In ''[[Literature/XWingSeries Solo Command]]'' a flagship's viewport is blown out, and there are a few moments where surviving crew can try to crawl to safety before the bridge is automatically sealed to prevent total atmosphere loss. A space station in ''Literature/GalaxyOfFear'' takes a minute before it's totally vacuum.
** When someone shoots a hole in the hull of ''Star of Empire'', in ''Literature/GalaxyOfFear'', atmosphere starts venting. Someone manages to plug the hole with something larger, keeping it there via air pressure, but the characters know it isn't sealed and after escaping the room they have it sealed off.
* Justified in ''Literature/TheAtrocityArchive'', where the sucking hole is a hole in ''reality'', working on sucking Earth's entire atmosphere through an interdimensional portal to [[spoiler: an alternate Earth where the atmosphere has frozen solid after the Jotunheimr sucked all the heat out of its home universe.]]
* In ''Literature/{{Ringworld}}'', the titular structure has a hole in it with air continuously leaking out into space. It creates a huge storm that looks like an eye from the side. However, given how incredibly huge Ringworld is, it would take a ''long'' time for all air to leak out. WordOfGod is that the erosion caused by the resulting superstorms would end all life on the ring long before that, though. There is another hole in the ring, caused by a meteorite impacting the outer section, creating a mountain on the inner side with a hole at the top. However, the mountain (and the hole) is above the atmosphere, so the leaking from this is negligible.

[[folder:Live Action TV]]
* ''Franchise/StarTrek'' is a big offender of this, especially in the modern series.
** But averted in an episode of ''Series/StarTrekTheNextGeneration'': when Geordi and Dr. Crusher depressurize a cargo bay to (a) put out a plasma fire and (b) get rid of some hazardous material, the wind lasted only a very short time. After that, the trick was repressurizing the bay before they passed out from anoxia. Although Dr. Crusher gave horrible advice by telling Geordi to hold his breath. In reality, holding your breath in vacuum would rupture your lungs. The right advice is to hyperventilate in advance to superoxygenate your bloodstream (which the two are seen doing), then exhale fully when decompression occurs.
** ''TNG'' actually used this as a solution to the problem of the week twice. In one episode, when stuck in a GroundhogDayLoop that ended in their deaths by way of spaceship collision, the solution was to vent the shuttlebay and push themselves backward. In another, it was used to try to force an alien lifeform to stop feeding on the ship, which failed.
** ''Series/StarTrekDeepSpaceNine'' did something similar in "Covenant". Dukat opens an airlock to kill a Bajoran woman. While the decompression lasts far longer than it should for a roughly 3 cubic meter room, it does cut off before the door finishes opening, leaving her to suffocate on the floor.
** In ''Series/StarTrekEnterprise,'' TNG's magic force field that lets ships go through but not air has not been invented, so when a bad guy takes his leave while Archer is still in the shuttle bay, he must deal with this. However, more realistically than most examples (including other ''Franchise/StarTrek'' examples), the fact that there's less and less air and pressure in the open shuttle bay every second is ''very much'' a problem.
* Averted in ''Series/{{Battlestar Galactica|2003}}'', where explosive decompression actually behaves like it should.
* Done in ''Series/{{Fringe}}.'' A saboteur on a [[ZeppelinsFromAnotherWorld Zeppelin]] is blown out of a hole ripped in the canvas outer hull near the keel. Anyone who knows anything about airships would tell you that Zeppelins are not pressurized in the first place (high-altitude War Zeppelins in UsefulNotes/WorldWarI used oxygen canisters and thick furs instead), and indeed it would be nearly impossible to do so for an entire Zeppelin airship, or even just the passenger decks, which on that type of aircraft are MASSIVE. Of course, the Zeppelin was an [[AllJustADream LSD-induced hallucination,]] but still. Olivia's airship knowledge sucks.
** It goes further than that. Either the writers or Olivia seriously slipped up on that scene. The entire point of decompression is that there is a meaningful pressure differential inside and outside. The Zeppelin was flying at a few thousand feet, tops. And it's not like the speed could have helped at all; there exists only ''one'' airship in the entire world today that is capable of traveling faster than 100 mph. This '''is''' ''Series/{{Fringe}},'' though. It's best not to look too deep into that show's fuzzy science.
* Not averted in Ron Moore's pilot movie ''Virtuality'', though -- in fact, this is one of the worst examples of all. A character is caught inside a small airlock when the outer hatch opens, and is buffeted by a huge torrent of wind for a couple of minutes before the other characters can shut the door. ''Where was all the replacement air coming from???''
* Happens in the 1970s ''Series/DoctorWho'' story ''The Mutants''.
** And in an earlier ''Who'' story ''The Moonbase'', which also features the subtrope of characters struggling to seal the hole as the air rushes out. One fan actually [[ShownTheirWork did the calculations]] to see how long it should have actually taken for decompression to happen. The results were something on the order of a few seconds. The scene in the episode lasted much longer, obviously.
** In the ''Doctor Who'' story ''Enlightenment'', Turlough is locked in a small chamber when the protective force field is deactivated letting the air escape to space. It takes several minutes for the Doctor to find Turlough, during which time it is still slowly evacuating though the hole is quite large and the room is quite small. Ironically it is also an example of ExplosiveDecompression, since when Turlough is rescued, he says "I would have exploded in the vacuum of space."
* When a plane is ripped opened in the third season of ''Series/{{Heroes}}'', air is continually blown out of the plane until it crashes about ten minutes later. (Probably due to the turbulence from the incredible windspeed outside the craft.)
* In the ''Series/{{Firefly}}'' episode "Out of Gas", Mal used this to put out a fire in ''Serenity's'' engine room. This is much more plausible because a fire merely needs to run out of oxygen to go out, and sealing/venting the room will help the fire use up all the oxygen, putting it out before it can damage too much equipment. Chemical fire retardants (e.g. the stuff in the red canisters and the stuff used for chemical fires) actually smother fires to put them out in real life, too!
** In "Our Mrs. Reynolds", Jayne [[spoiler:shoots out the viewport of an energy net-equipped space station to kill the crew and save the ship]].
*** Jayne [[spoiler:does it to kill the crew of the station. He explicitly asks Mal earlier if Mal wants him to shoot the window and Mal says it'd kill some folk, but wouldn't save the ship - so after Jayne saves the ship by shooting the arc projectors, he shoots the window to kill the people responsible for them.]]
* In the ''Series/StargateSG1'' episode "Prometheus", [[spoiler:Jack uses this to [[ThrownOutTheAirlock kill Col. Simmons]]]].
* The "remaining air" part is often ignored in the live-action marionette series, ''Series/{{Thunderbirds}}'', most notably in The Vault of Death where the worker trapped inside would certainly have died from anoxia long before he could be rescued if not for [[CartoonPhysics Fictional Physics]] which dictate that a person doesn't die until '''all''' the air runs out.
* In the ''Series/{{Supernatural}}'' episode [[Recap/SupernaturalS01E04PhantomTraveller "Phantom Traveler" (S01, Ep04)]], there is a continuous wind after the airplane door is opened by a demon.
* ''Series/TheNewAvengers'': In "Trap", Steed, Gambit and Purdey are on a plane when the main cabin starts filling with gas. Gambit opens the main door to depressurize the cabin and suck out the gas. The depressurization goes on for long enough for the pilot get out of the cockpit and still be sucked out of the plane.
* In an episode of ''Series/SevenDays'', Parker has to [[TimeTravel Backstep]] into orbit in order to keep a SpaceStation from breaking up on re-entry and contaminating the atmosphere. While he's aboard the station, one of the compartments is punctured, resulting in an astronaut being thrown towards the small hole and plugging it in. Parker and the other astronaut try to save him, only for him to tell them to get out and seal him in, as his body is the only thing temporarily keeping the air from rushing out, and he can already feel the hole expanding.

[[folder:Video Games]]
* Opening an airlock in ''VideoGame/DeadSpace'' will cause a few seconds of windy turbulence (that's not how airlocks work!) but later an entire deck has its atmosphere vented into space with a minimum of fuss.
** While it can be understandable that internal doors to damaged sections might leak air, this also happens with doors designed to lead into space. The fact that Isaac and Kendra are hacking the doors and the damage to the ship might explain some things.
** There are fragile windows in ''VideoGame/DeadSpace2'' that when broken will blow enemies out into space and Isaac will be dragged along....before being crushed by a door closing.
* The ''{{Franchise/Halo}}'' series averts this, with the games depicting airlocks cycling realistically, and the books at least not mentioning a wind when decompression is involved.
* The final challenge in ''VideoGame/ConkersBadFurDay'' features Conker in a life-or-death battle with a xenomorph-like alien on a spaceship (long story). Near the start of the fight, Conker has to blow the airlock, producing a constant state of decompression as air keeps rushing out. This decompression lasts the entire battle, no matter how long it takes (and even if you pull it off quickly, it's still more than a bit absurd), and has to use said decompression to throw the alien out. [[SarcasmMode The ship's onboard computer helpfully reminds him of this fact]].
* Justified in in ''VideoGame/{{Portal 2}}''. [[spoiler:When Chell opens a portal on the moon, there is a continuous decompression effect until the portal is shut.]] Spaceships and the like may have a limited volume of air, but this portal has to equalize the pressure of ''an entire planetary atmosphere''. Blowing out this much air takes ''lots'' of time--far, ''far'' more time than the portal is open for.
* Subverted for what the Star Fissure does at the end of ''VideoGame/{{Riven}}''. For one thing, it's an anomaly in the Age itself that opens to a void ''that has air in it'', and just looks like a vacuum because of how badly Gehn wrote the Age. He lampshades this in his journal, but is too egotistical to think he is at fault. This is proven later in ''VideoGame/{{Uru}}'' where the same Fissure appears in [[spoiler: Relto]], but has no vacuum effect.
* Averted in ''VideoGame/SpaceStation13'' on those servers using more realistic atmospheric simulation models.
* In ''VideoGame/StarCommand'', a powerful hit near the outer hull of your ship will, most likely, result in a hull breach. As long as your DeflectorShields are down, the air will appear to be rushing out. However, none of your crew will suffer any ill effects as long as they're not near the hole. Anyone near the hole will get instantly blown out into space. This includes enemy [[BoardingParty boarding parties]] that beam in at intervals when your shields are down.
* Played completely straight in ''VideoGame/SonicAdventure2'', during most of the many missions aboard the ARK, certain portions of the space station can be blown out and you yourself can be blown into the void... and not one mention goes to what would happen if you just stood there... waiting for the air to be blown out of the entire station.
* One of the first tasks in ''VideoGame/MissionCritical'' is to repair a hole in one of the quarters leading out into space as a result from the battle in the intro. The hole is fairly small and easy to fix. When you enter the room, you see a horizontal twister of sorts but don't actually suffer any ill effects. In fact, this is one of the TakeYourTime "critical" tasks. It's not clear why the quarters can't simply be sealed off.
* Subverted In ''Videogame/{{Warframe}}''. Shooting out windows on Corpus ships will make the air rush out, but the doors will lock to keep the depressurization from spreading, though we still have the odd part about how everyone and everything remains planted to the floor. There ''are'' armored bulkheads that can seal off the leaks, but the player has to manually activate them.
* Subverted in ''VideoGame/FTLFasterThanLight'': Rooms exposed directly to space (i.e. usually open airlocks) will depressurize instantly, but adjacent rooms whose doors are open will depressurize at a slower rate depending on how far they are from the outside of the ship. Rooms whose doors are closed will not depressurize at all unless they receive a bulkhead breach, and rooms with a bulkhead breach will depressurize at a moderately steady rate regardless of whether they're open to space.

* ''Webcomic/SchlockMercenary'' has it fairly realistically [[ here]], where an accident blows a 300 meter hole in the side of Credomar, a cylindrical station[[spoiler:-cum-DeathRay]] measuring 6 kilometers by 60.

[[folder:Western Animation]]
* ''WesternAnimation/{{Futurama}}'' was probably parodying Star Trek when they did this.
* This happens in one episode of ''WesternAnimation/TheJetsons'' where George winds up traveling with a circus troupe. George accidentally plugs up the hole with his butt all the way until the ship lands, including during re-entry.
* In the ''WesternAnimation/DarkwingDuck'' episode [[Recap/DarkwingDuckS1E22WhenAliensCollide "When Aliens Collide"]], Darkwing's plane, the Thunderquack, smashes a hole in the side of an Outer Space Patrol ship, and when escaped criminal Wacko takes off in the Thunderquack, everyone left inside the OSP ship is in danger of being sucked out of the hole as if it were the opening of a giant vacuum cleaner.
