On 22 Oct. 1922 Lt. Harold Harris was testing this plane equipped with experimental ailerons and hassling with a Thomas Morse scout when, in a tight turn, the ailerons went into flutter and the plane disintegrated. Harris jumped and became the first US military pilot to be saved by a parachute (which he only grudgingly put on that morning). This happened at McCook Field in Dayton, OH 125 years to the day after the first successful descent by parachute from a baloon in 1797 in France.
