F2, a "flying body configuration" built by Northrop. The audio  sound effects are from a crash that occurred on May 10, 1967, at  Edwards Air Force base in California (although the dialog heard was  recorded by Majors). The test pilot, Bruce Peterson, hit the ground  at 250 mph, tumbling six times. He lost use of his right eye and had  to stop flying, ending his career. Understandably, Peterson has said  that he hated reliving his accident, week after week, courtesy of  the show.
