Hangar 18

Hangar 18 is an Air Force base in Dayton, Ohio where the alien bodies were taken when a UFO supposedly crashed in Roswell, New Mexico in 1947. The remains were later taken to Area 51 in Nevada, and many people believe they are still there. Dave Mustaine of Megadeth explained when the album was released: "'Hangar 18' is about military intelligence – two words combined that don't make sense. I can't understand why they're hiding stuff from us. It's our country, too. But see, they run it, and the more I get into politics, the less I become a musician."

The video, directed by Paul Boyington, depicts an alien landing in Roswell. The song that plays at the beginning of the clip is another Rust In Peace track, "Dawn Patrol."

Dave Mustaine, who was a member of Metallica until he was fired in 1983, wrote this song. The main riff of this song is similar to Metallica's "The Call Of Ktulu" which appeared on their Ride The Lightning album. Mustaine had composer credits on that song, but he was kicked out of Metallica before the album was released.
