RAF Cammeringham, UK
RAF Cammeringham (formerly RAF Ingham) was a Royal Air Force station used by RAF Bomber Command between 1940 and 1945 and the Polish Air Force until 1946. The airfield was located between the A15 (Ermine Street) and B1398 roads, 10.3 mi (16.6 km) north of the county town Lincoln, Lincolnshire, England and due east of the village of Ingham. Mainly used as an overflow airfield for nearby RAF Hemswell and later as a training establishment, its continued use was limited by damage to its grassed runways. The airfield closed in early December 1946. The site had been considered as a potential stand-alone airfield as early as 1936 but building did not commence until 1940 when RAF Hemswell needed additional capacity during the expanding World War II bomber offensive. Initially no squadrons were based at the station and it was used exclusively by Hemswell as an overflow site. Detailed surveys were undertaken in preparation for the building of the concrete runways then needed for heavy bombers, but it was decided that the contour gradients were unsuitable and the runways remained grass only. However between 1940 and 1942 a concrete perimeter track was constructed, together with three hangars (1 x B1 and 2 x T2 types) and a technical site. A total of 36 pan-type aircraft standings were constructed in two phases.
