We can date this photo after 1947 because of the acronym USAF. The United States Air Force was formed in 1947 and previously had been called the US Army Air Corps or the US Army Air Services. Prior to the Air Force being established as an independent branch of the US military, air operations were jointly handled by the Army for land based operations and the Navy or Marine Corps for sea based operations. My uncle and my father in law were in the Air Force, although they never knew each other. This photo shows two men at the doors of what is obviously a flight school.
Who Were They?
