It's used on dozens of television shows, many of them making it an ongoing threat or means of execution. Science fiction films like Alien, Sunshine, and Event Horizon have used airlocks in graphic ways to dismember or jettison one of the heroes (or main villain in the case of Alien and Aliens). Other times the airlock can even be used comedically, like in Austin Powers or Galaxy Quest.
This is a round up of all of those times airlocks featured prominently - and awesomely - in your favorite science fiction from both the small and big screens. Vote up the movies and TV shows that used the airlock the best - whether to rid a ship of cylons, or to get laughs.
At the end of the film, the only way to kill the Xenomorph discharge it from the airlock... and it's awesome.

Just as in Alien, seemingly the only way to kill the Xenomorph is to throw it out the airlock. In this case, Ripley does so with the beastly front loader.

The airlock basically becomes the central antagonist at one point in this 2015 Ridley Scott film. After having survived for weeks on Mars with food he was able to grow himself (science!), Mark Watney (Matt Damon) *SPOILER* lost everything when an airlock blew, destroying all of his crops.

In the episode "Ariel" Mal (Nathan Fillon) almost launches Jayne (Adam Baldwin) from the airlock for ratting out Simon and River to the Feds.
As well, in the pilot episode, Mal threatens Simon with the same fate if he fails to save Kaylee.

David Bowman rushes out in another pod to rescue Frank Poole, who was being attacked by HAL 9000, but in the hubbub, he forgets his helmet. Oops.
HAL then refuses to open the pod bay doors so Bowman can reenter the Discovery. Since Bowman doesn't have a helmet, he has to throw himself out of the airlock so he can get back into the spaceship.

Justin (Jack Noseworthy) is taken over by the Event Horizon and almost kills himself (very messily) using the airlock on the ship.

In prime Alien tradition, not only does the alien/human hybrid get taken out by the airlock in this one, it's taken out, slowly - piece by piece - sucked through a small hole and scattered into space.

This show used airlocks so much that it became a verb! To airlock someone was to execute them, and it happened A LOT.
