Royal Air Force Bourn or more simply RAF Bourn is a former Royal Air Force station located 2 miles north of Bourn, Cambridgeshire and 6.9 miles west of Cambridge, Cambridgeshire, England. Bourn Airfield was constructed for RAF Bomber Command in 1940 as an airfield for nearby RAF Oakington. It was used by No.101 Squadron RAF Vickers Wellingtons for training purposes from 23 July 1941, two more raids on the 8th and 23 May 1944 were made, the latter damaging two parked de Havilland Mosquitoes. As the strategic bombing offensive intensified, the losses mounted. By the time of the last operational sortie on 4 April 1945, a total of 164 aircraft had been lost, either from the squadrons based at Bourn or from others trying, and failing, to land on the field. The average age of aircrew was 23 and over a third of these were under 20 years of age, of the 886 listed names,648 were killed and many of the 35 injured subsequently died of their wounds. The number killed was probably greater than that of the population of the village at the time. 97 Squadrons Avro Lancasters were replaced by the Mosquito IXs of 105 Sqn in March 1944 and these Oboe-equipped aircraft were able to identify targets with great precision and then mark them accurately. In December 1944,162 Squadron was formed at Bourn with Canadian-built Mosquito XXs and XXVs which flew almost nightly to Berlin, the two squadrons operated together from Bourn for much of the rest of the war. From 1941 to 1945, damaged Short Stirlings were repaired and test-flown from Bourn and these were transported to the airfield from the Sebro factory near Madingley which later continued its work with RAF and United States Army Air Forces, Consolidated B-24 Liberators. The Bourn and Madingley units together employed up to 4,500 personnel, by 1948, the station was closed and the last sections were sold off for agricultural use in 1961. Now the Rural Flying Corps uses part of the runway for light aircraft, on Bank Holidays, Bourn Market uses much of the old runways for stalls.
