Before this many of the pilots training with No. 20 AFU received their Beam Approach Training at RAF Feltwell. Both No. 1538 BATF and No. 20 AFU remained at RAF Croughton until 18 October 1944 when the airfield returned to Flying Training Command. On this date No. 1538 BATF disbanded and No. 20 AFU retired to Kidlington. RAF Flying Training Command needed the station to reform No. 1 Glider Training School. The decision to reopen glider training came about when the army finally agreed that the glider pilots should be RAF. From the beginning both the RAF and Army had differing opinions as to who should pilot the gliders. The Army felt the Glider Pilot Regiment was an elite force and that the pilots should be from the Army or at the very least trained to the same standard. The Army even rejected a proposal from the RAF to have a RAF pilot sit in the second pilot or co-pilot seat. This changed after Operation Market Garden. During the Arnhem portion of that operation 460 glider pilots were either killed or captured, with another 150 wounded. The Army agreed to let the RAF help fill the vacancies in the Glider Pilot Regiment. Of the planned 1,000 trained glider pilot target figure, to be reached by April 1945, the RAF proposed to fill 500. No. 1 GTS arrived at RAF Croughton on 1 November 1944. Training continued until after the war and even included the addition of a Glider Instructor Flight. During August 1945 No. 1 GTS came under the command of No. 21 Heavy Glider Conversion Unit RAF at RAF Brize Norton. Flying and training ceased on 25 May 1946. With No. 1 GTS leaving RAF Croughton, its remaining aircraft, Hotspurs and Masters worth preserving, moved to No. 3 GTS at RAF Wellesbourne Mountford. Postwar – United States Air Force use From 1947 to 1950 the Station remained fairly quiet and forgotten except for its occasional use as an ammunitions store. That all changed towards the end of 1950 when the USAF took over the station when the 1969th Communications Squadron at RAF South Ruislip formed a detachment at RAF Croughton. This began RAF Croughton's new communications mission. Over the next several decades the units stationed at RAF Croughton changed many times, but the mission remained communications. In 1955 this detachment became the 1230th Airways and Air Communications Service Squadron
