The 33rd Flying Training Squadron is a United States Air Force squadron based at Vance Air Force Base near Enid, Oklahoma. It is a part of the 71st Flying Training Wing. The squadron was established as a medium bomber unit on Bolos, Marauders, and later B-25 Mitchells. It became a heavy bomber squadron in February 1944, and was later equipped with B-29s and B-47s before being inactivated in 1963. Just under thirty years later, it was reactivated as a flying training squadron.
