McDonnell F-4A Phantom II in the NASA Flight Research Center hangar undergoing maintenance inspection in preparation for a flight. Notice the large inlet on the right side of the fuselage, the tandem cockpit, and the wing tip folded in an upward position. The F-4A (Navy serial number 145313) arrived at the Flight Research Center (later redesignated the NASA Dryden Flight Research Center) on December 3, 1965. It was damaged by an inflight explosion on July 25, 1967. Able to land despite the explosion, it was later returned to the Navy.
