Home Aircraft Depot, Henlow
WWI The Home Aircraft Depot was set up for reconditioning of aircraft and their engines.
Post-WWI It was the only unit of its kind at home in the Royal Air Force entirely devoted to the reconditioning of aircraft and their engines.
By 1931 The Home Aircraft Depot, part of the Royal Air Force, was the only unit in Britain entirely devoted to the reconditioning of aircraft and their engines. Also the centre for final training of aircraft riggers and fitters in the service - for this reason a proportion of the repairs and overhauls necessarily arising from the use of aircraft is diverted from its normal route back to the manufacturer's works and taken to Henlow.
Presumably later the site of the R.A.F. Technical College, Henlow
