Airlocks
Airlocks are small chambers that separate two different environments and allow the passage of people between these different environments. Generally they contain two airtight doors and a means to equilibrate the environment of the chamber to match whatever area is being entered. Fictional airlocks may sperate the interior of a spaceship from space or may separate the interior of an undersea habitation unit from the waters of the ocean. They may be paired with a decontamination chamber, especially if located on an off-world research station or alien planet. Airlocks are home to mutinied ship captains, alien creatures, and deep space raiders preparing to board.

Designing Fictional Airlocks
Overview
When designing airlocks, consider the controls that operate it and where they are located. Often in narratives, airlocks are a means to dispose of an unlucky person or an unwanted creature into space. They may also serve as a temporary jail cell. This may mean that the controls are located outside of the chamber itself.

Design
- Size and Scale: Airlocks can range from cramped, single-person chambers for emergency use to massive cargo bays large enough to accommodate entire spaceships.
- Shape and Configuration: Circular, cylindrical, and rectangular airlocks are common, but designers often employ more unusual shapes to suit the aesthetic or function of the fictional setting.
- Automation and Control Systems: Depending on the technological level of the universe, airlocks might be entirely automated or require manual operation through a complex control panel. Biometric scanners or access codes could be implemented for added security.
- Observation Windows: Large, reinforced windows are a recurring feature, allowing characters (and the audience) to peer into the alien environment or the vast emptiness of space.

Narrative Events
- Sites of suspense: Malfunctioning airlocks or breaches can create life-or-death situations, raising the stakes for the characters.
- Limbo zones: The transitionary space of an airlock can represent a character’s physical and psychological journey between worlds.
- Stages for dramatic reveals: The first glimpse of an alien landscape or a new crew member might be through the window of an airlock.
