The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting the Distinguished Flying Cross to First Lieutenant (Air Corps) Harry A. Sutton, U.S. Army Air Corps, for extraordinary achievement while participating in an aerial flight. Between the dates 15 and 22 December 1926, Lieutenant Sutton at Santa Monica, California, at great personal hazard piloted an O-2 airplane in test to determine the spinning characteristics of this type of plane, which resulted in invaluable data being made available to airplane designers. This test was voluntary and above the call of duty and reflect great credit on the Air Corps and the Army of the United States.
