The Distinguished Flying Cross (DFC) is the third-level military decoration awarded to personnel of the United Kingdom's Royal Air Force and other services, and formerly to officers of other Commonwealth countries, instituted for "an act or acts of valour, courage or devotion to duty whilst flying in active operations against the enemy". During World War II, 20,354 DFCs were awarded, the most of any award, with approximately 1,550 first bars and 45 second bars.
