context_page_description: Boreham is a village and civil parish, in Essex, England. The parish is in the City of Chelmsford and Chelmsford Parliament constituency. The village is approximately 3.7 miles northeast from the county town of Chelmsford.
context_section_description: A forest near the village was felled in 1943 to build a military airfield, and the three one-mile (1,600 m) runways of RAF Boreham opened in 1944. It hosted elements of the US Army Air Forces 394th Medium Bomb Group (flying B-26 Marauder bombers) and later the 315th Troop Carrier Group flying C-47s.  After the Second World War the three runways were adapted into a roughly triangular motor racing circuit Boreham Circuit, which held competitive meetings between 1949 and 1952. It was bought by Ford in 1955 for use as a development test track. Ford Motorsport moved to Boreham in 1963, and although some of the track was removed for gravel quarrying in 1996 the remaining track surface continues to be used for testing. Essex Police Air Support Unit have been based at the airfield and in 1990 began using Boreham airfield as a control centre for its fleet of helicopters. From 1997 to 2010, Essex Air Ambulance was also based at the site.
