U.S. Marine Corps test pilot Lt. Col. Fred Schenk flies a mission May 10 in F-35B Joint Strike Fighter test aircraft BF-1. The mission expanded the aircraft’s flight envelope in short takeoff and vertical landing mode, and was the 200th flight for the aircraft. The F-35B is the variant of the Joint Strike Fighter for the U.S. Marine Corps, capable of short take-offs and vertical landings for use on amphibious ships or expeditionary airfields to provide air power to the Marine Air-Ground Task Force. The F-35B is undergoing test and evaluation at NAS Patuxent River prior to delivery to the fleet. (Photo courtesy of Lockheed Martin)
