Lockheed P-80R. On June 19, 1947, at Muroc Army Air Field (now Edwards Air Force Base), Calif., Col. Albert Boyd flew this P-80R to a new world's speed record of 623.753 mph, returning the record to the United States after nearly 24 years. The Army Air Force's quest to capture the world's speed record -- then held by a British Gloster Meteor -- after World War II led to the creation of the specialized P-80R. A high-speed variant of the standard P-80A Shooting Star, it had a smaller canopy, redesigned air intakes and a shorter wing with an extended leading edge. In addition, the engine was modified, armament removed and replaced by a fuel tank, and all drag-producing openings sealed.
