Visited with Gangeox recently.
Raf Upwood is located next to the village of Upwood, Cambridgeshire. It is close to Huntingdon and Raf Alconbury. It closed in 1994 and is now derelict. Only the Aircraft Hangers remain in use but belong to a private company.
The site was requisitioned by the Royal Flying Corps in 1917 and opened in September of that year. It was known as Bury, being close to that village. At this time it was only used for night landing as a satellite field for 75 Squadron based in Elmswell, Suffolk. The site was expanded in 1918, with new buildings being erected including five hangers and a watch tower. It was then renamed to Upwood. As World War I ended the air field was no longer required, so in June 1919 it closed, all the buildings were flattened and the land returned to the local community.
The Air field was reopened in the early 1930's as Britain saw the need for an improved Airforce. New buildings were built and the base designed to house two medium bomber squadrons with room for a third if needed.
