No 1 School of Technical Training (No 1 SoTT) is the Royal Air Force’s aircraft engineering school. From 1919 to 1993, the No 1 SoTT was based at RAF Halton and from 1920 until 1993 the School was the home of the Aircraft Apprentice Scheme. This scheme, which included Sir Frank Whittle "father of the jet engine", trained RAF technicians on a 3 year course, the graduates of which were the best trained technicians in the RAF and would usually go on to become Senior NCOs.
In 1952 the No 1 SoTT received royal recognition when Her Majesty Queen Elizabeth II presented the School with a colour. The colour was received on behalf of the school by the 63rd Entry of aircraft apprentices; the colour party being Sergeant Aircraft Apprentice (S/A/A) F.M. Hines, and identical twins S/A/A’s Clive and Richard Grant.
From 1993 to the present, the No 1 SoTT has been based at the Defence College of Aeronautical Engineering, Cosford (formerly RAF Cosford).
