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.
