"Hangar 18" is a song by American heavy metal band Megadeth from the 1990 album Rust in Peace. UFO conspiracy theories, or possibly Hangar 18, the 1980 film based on those theories, inspired drummer Nick Menza to write the lyrics. Shortly thereafter, frontman Dave Mustaine composed the music. Hangar 18 is located at Wright-Patterson Air Force Base near Dayton, Ohio, and it is speculated that an alien aircraft was brought there from Roswell in 1947. The song reached number 25 on the Irish Singles Chart, also reached number 26 on the UK Singles Chart. 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. "Hangar 18" was nominated for Best Metal Performance at the 1992 Grammy Awards. (wiki)
