In WWI Turnberry housed No. 1 School of Aerial Fighting (Loch Doon, to the east, was used for a School of Aerial Gunnery). The school merged with No. 2 (Auxiliary) School of Air Gunnery, becoming No. 1 School of Aerial Fighting and Gunnery, renamed No. 1 Fighting School (North-West Area) on 29 May 1918. It provided pilots with three-week courses in the arts of aerial gunnery and combat. It was disbanded on 25 January 1919. The Turnberry Hotel was used during the war as a hospital for the wounded.[4]
Inter war period
Following the end of the conflict, all land and property requisitioned for military purposes was returned to civilian ownership. Golf courses 1 and 2 were rebuilt and renamed "Ailsa" and "Arran". A memorial honouring lost airmen at Turnberry was erected on the hill overlooking the 12th green of Ailsa.[5]
Second World War
With outbreak of the Second World War, the hotel was again commissioned by the British government as a hospital, and the golf courses were requisitioned for air training for the Royal Air Force.
