The unusual aircraft flew some 2,500 research flights and contributed to the advancement of many of the flight technologies integral to today's fleet. Prior to its retirement, the TIFS, a 1955 Convair, was the oldest operating aircraft in the Air Force inventory. (U.S. Air Force photo/Ben Strasser)
