FAIRMONT, Okla. (AP) — A preliminary federal report says a biplane performing acrobatics flipped over into an inverted flat spin before crashing 10 minutes after takeoff in northern Oklahoma.
Fifty-five-year-old pilot Randall Lee Harris and 25-year-old Air Force Lt. Dale Bryan Shillington died July 21 when the Runyan/Harris Skybolt 300 experimental aircraft crashed near Fairmont.
The undated National Transportation Safety Board report says an area resident watched the airplane barrel roll, climb and tumble, then roll over into an inverted flat spin.
The witness watched it disappear behind trees then he heard the crash.
The report says Shillington's wife told the agency the flight was arranged "last minute."
A final report including a possible cause of the crash generally takes several months to complete.
Fairmont is about 75 miles north of Oklahoma City.
