Clipped the top of a barn before impacting a ploughed field. Pilot, Major Stephen W. Simmons, was buzzing his in-laws, since they own the property. He was in the process of completing a loop, starting at 140 feet with a top of only 4,759 feet. Unfortunately he wasn't able to complete the loop and never ejected. Time of the crash was 18:00 hours, 4 miles from Tulla, Texas. Eye witnesses said the aircraft lost power and then crashed. Simons was a pilot with Delta Airlines and was flying a cross-country mission from Hill AFB back to NAS Fort Worth.
