RAF Upper Heyford was a Royal Air Force station located 5 miles (8 km) north-west of Bicester near the village of Upper Heyford, Oxfordshire, England.
The station was first used by the Royal Flying Corps in 1916 but was not brought into use for flying until July 1918 by the Royal Air Force. During the inter-war years and continuing through the Second World War until 1950 Upper Heyford was used mainly as a training facility. During the Cold War, Upper Heyford initially served as a base for United States Air Force Strategic Air Command (SAC) strategic bombers and later United States Air Forces In Europe (USAFE) tactical reconnaissance, fighter and fighter-bomber aircraft in the UK.
Upper Heyford was unique among airfield in the United Kingdom as only the flight-line area required military identification to access. The rest of the station, save the commercial facilities, was accessible to military and non-military alike. Upper Heyford was also unique in that the airspace around the station (from the surface to 3500') was protected by a mandatory radio area (UHMRA) in which private pilots were required to be in contact with the base controllers on frequency 128.55 when flying past or overhead.
