The Flying Division, Air Training Command, was a training formation of the United States Air Force. The unit was established in 1926 as the Air Corps Training Center to be the primary pilot training center for the Air Corps. It was reorganized into one of three training commands created by the Office of the Chief of the Air Corps in 1940 to accommodate the large number of air cadets being recruited as a result of the expansion of the corps after the fall of France. During World War II, thousands of cadets attended various flight schools throughout the Central United States being trained as pilots for fighters, bombers and transports. It also trained the navigators, bombardiers and gunners necessary for the bombers to attack enemy targets in the combat areas overseas. After World War II, it became the primary pilot and aircrew training unit of the United States Air Force Air Training Command.

The Air Training Command (ATC) is a former United States Air Force (USAF) Major Command designation. It was headquartered at Randolph Air Force Base, Texas, but was initially formed at Barksdale Air Force Base, Louisiana. It was re-designated as Air Education and Training Command (AETC) following a merger with Air University (AU) on 1 July 1993.
