The military airfield of RAF Ingham was constructed as an all-grass airfield. It was intended as a satellite for Hemswell, and was ready for use as such on the 20th of March 1940. It was not occupied by aircraft at this time, however, rather functioning as a relief landing ground. Construction of a concrete perimeter track was started in April 1942, with aircraft being stationed at the airfield in May 1942. These first aircraft were the Vickers Wellington bombers of 300 (Polish) Squadron, which operated from Ingham until January 1943, when the squadron returned to Hemswell. 300 Squadron returned in June 1943, along with 305 (Polish) Squadron who also briefly occupied the airfield. The airfield began to be used as a training facility from March 1944, with a variety of training flights and units occupying the site. The station was re-named as RAF Cammeringham on the 20th November 1944, to avoid confusion with another station in Suffolk also called Ingham. The base was used by various non-operational training units until December 1946, when the station closed. Today much of the 650 acres (265ha) has been returned to agricultural use and most of the concrete perimeter track and the dispersal areas have been removed. {1}{2}{3}{4}{5} The airfield had three grass runways, 35 'frying pan' shaped hard standings, two type T2 aircraft hangars and one type B1 hangar. Temporary accommodation for the personnel was provided; in December 1944 these numbered 1267 men and 134 women. {6}
