Joe Walker was the first to fly the variable-geometry wing X-5 to a full 60-degree wing-sweep angle, adjusted in flight.
Joe Walker was the first to fly the variable-geometry wing X-5 to a full 60-degree wing-sweep angle, adjusted in flight. The X-5 derived from the Messerschmitt P.1101, a German experimental aircraft from WWII whose wing angles could only be adjusted on the ground. The concept has since been used on the F-14, F-111, and B-1 aircraft.NASA Photo
