Lockheed Martin NF-16D Fighting Falcon VISTA

The General Dynamics (now Lockheed Martin) F-16 VISTA ("Variable stability In-flight Simulator Test Aircraft") is an experimental aircraft, derived from the F-16 Fighting Falcon, which was modified as a joint venture between General Dynamics and Calspan for use by the USAF. The F-16 VISTA testbed aircraft incorporated a multi-axis thrust vectoring (MATV) engine nozzle that provides for more active control of the aircraft in a post-stall situation. The resulting aircraft is supermaneuverable, retaining pitch and yaw control at angles of attack beyond which the traditional control surfaces cannot change attitude.
