7 May 1975 The second prototype General Dynamics YF-16A Fighting Falcon, 72-01568, on a practice flight prior to deployment for the Paris Air Show, suffered a failure of the main undercarriage leg to extend.
General Dynamics test pilot Neil Anderson flew the aircraft until the fuel was nearly exhausted and then made an expert grass belly-landing at Carswell Air Force Base, Texas. The aircraft was not heavily damaged and the pilot was uninjured. The airframe was then sent to Rome Air Development Center Newport Site for use in radar tests. This was the first F-16 mishap.
