The Distinguished Flying Cross (DFC) is a military decoration of the United States Armed Forces. The medal was established on July 2, 1926, and is awarded to those who, after April 6, 1917, have distinguished themselves by single acts of heroism or extraordinary achievement while participating in aerial flight. Both heroism and extraordinary achievement are entirely distinctive, involving operations that are not routine. The medal may be awarded to friendly foreign military members in ranks equivalent to the U.S. paygrade of O-6 and below in combat or support operations.
