The song is also particular in that the bass uses a different tuning from the two lead guitars, the bass being in Drop D while the guitars are in standard tuning.
A sequel to this song called "Return to Hangar" was included on Megadeth's ninth album The World Needs a Hero. It tells the fictional story of the life-forms said to be contained in Hangar 18 coming back to life and killing those inside the building before escaping.
The "Hangar 18" video is themed after the song's lyrical concept. It depicts the torture of aliens and, at the end, shows all the band members in freezing chambers. The video was shot in San Pedro, Los Angeles at a Water & Power building. Coincidentally, the band would film the video for "Crush 'Em" on this same site nine years later. An edited version of "Hangar 18" is typically shown on MTV2 which has the song length cut down drastically. During the intro to the video the song "Dawn Patrol" from the Rust in Peace album can be heard in the background.
