The United States Air Force celebrated its 66th birthday Friday at the Air Force Memorial near the Pentagon.
The celebration included a concert by the United States Air Force Band and the Singing Sergeants, as well as a ceremonial demonstration by the Air Force Honor Guard.
The Air Force was created Sept. 18, 1947, as a result of the National Security Act. The youngest branch of military, it had previously been a division of the United States Army.
