04/30/2009. Remarks by Johan Visschedijk: "The first YF-17 prototype was loaned to NASA Dryden Flight Research Center, Edwards, California, from May 27 to July 14, 1976, for maneuverability studies at transonic speed, collecting data on after-body pressures, vertical-fin dynamic loads, pilot physiology, and infrared signatures.
Subsequently the aircraft was used by McDonnell Douglas and Northrop in support of the F-18 program, the direct development of the YF-17, ordered by the USN as the F/A-18 Hornet on May 2, 1975. The aircraft is preserved at the Western Museum of Flight in Hawthorne, California."
