Distinguished Flying Cross.
First cross awarded in 1929 with citation:
"For extraordinary achievement while participating in an aerial flight. On 4–5 September 1922, Lieutenant Doolittle accomplished a one-stop flight from Pablo Beach, Florida, to San Diego, California, in 22 hours and 30 minutes elapsed time, an extraordinary achievement with the equipment available at that time. By his skill, endurance, and resourcefulness he demonstrated the possibility of moving Air Corps units to any portion of the United States in less than 24 hours, thus reflecting great credit on himself and to the Army of the United States."
Second cross awarded in 1929 with citation:
"For extraordinary achievement while participating in an aerial flight. During March 1924, at McCook Field, Dayton, Ohio, Lieutenant Doolittle, piloting a Fokker PW-7 pursuit airplane, performed a series of acceleration tests requiring skill, initiative, endurance, and courage of the highest type. In these tests a recording accelerometer was mounted in the airplane and the accelerations taken for the following maneuvers. Loops at various air speeds; single and multiple barrel rolls; power spirals; tail spins; power on and power off; half loop, half roll, and Immelmann turn; inverted flight; pulling out of dive at various air speeds; flying the airplane on a level course with considerable angle of bank; and flying in bumpy air. In these tests the airplane was put through the most extreme maneuvers possible in order that the flight loads imposed upon the wings of the airplane under extreme conditions of air combat might be ascertained. These tests were put through with that fine combination of fearlessness and skill which constitutes the essence of distinguished flying. Through them scientific data of great and permanent importance to the Air Corps were obtained."
Second DFC awarded in the form of a bronze oak leaf cluster to be worn on the ribbon of the first DFC. War Department, General Orders No. 16.
Third cross awarded in 1942 with citation:
"For extraordinary achievement as Pilot of a B-25 Bomber and Commanding Officer of the 1st Special Aviation Project (Doolittle Raider Force), while participating in a highly destructive raid on the Japanese mainland on 18 April 1942. Colonel Doolittle with 79 other officers and enlisted men volunteered for this mission knowing full well that the chances of survival were extremely remote, and executed his part in it with great skill and daring. This achievement reflects high credit on himself and the military service."
Third DFC awarded in the form of a second bronze oak leaf cluster to be worn on the ribbon of the first DFC. War Department, General Orders No. 16.
