F-18 HAARV High Alpha (angle of attack) Research Vehicle was an American modified McDonnell Douglas F/A-18 Hornet used by NASA in a 3-phase program investigating controlled flight at high angles of attack using thrust vectoring, modifications to the flight controls, and with actuated forebody strakes. The program lasted from April 1987 to September 1996

In 1991 flight of High Angle of Attack Rsrch Vehicle (HARV) with thrust vectoring.

Nobody knows exactly where "Rat 55" lives or precisely what technology it uses to accomplish its mission, but it sure is an exotic beast. The USAF's secretive NT-43A testbed is a highly modified 737-200 that goes far beyond ground-based radar and infrared signature testing on stealthy aircraft by plying its trade high up in the sky in their target aircraft's natural operating environment.

The Experimental Curtiss-Wright XP-55 Ascender (1943) never achieved the sort of performance that was originally promised as it was massively underpowered.

Curtiss-Wright Ascender The Curtiss-Wright Ascender prototype was born out of a United States Army Air Corps request for a higher-performance, more heavily armed fighter with improved pilot visibility over existing aircraft.

The Douglas Globemaster II, nicknamed "Old Shaky", was a heavy-lift cargo aircraft built by the Douglas Aircraft Company. The was the primary heavy-lift transport for United States Air Force Military Air Transport Service (MATS) during the and early

30 October 1963 when the U.S. Navy decided to try to land a Hercules on an aircraft carrier, the USS FORRESTAL. Lockheed's only modifications to the original plane included installing a smaller nose-landing gear orifice, an improved anti-skid braking system, and removal of the underwing refueling pods.The crew successfully negotiated 29 touch-and-go landings, 21 unarrested full-stop landings, and 21 unassisted takeoffs.
