ST3660 : RAF Locking site after demolition I wonder how many airmen/airwomen passed through this training camp? I was trained there on three occasions during the 1960s. It was a major training facility for electronics, with emphasis on practical training; theory being undertaken at Compton Basset, Melksham and other Witlshire camps. Prior to that it was used to put together aircraft which then taxied down the very wide road to the airfield some 5 or so miles closer to Weston.
