and other countries. 106 Entry, which passed out in December 1966, was the last of the Aircraft Apprentice entries. A three-year Technician Apprentice scheme, a two-year Craft Apprentice scheme, and a one-year Administrative Apprentice scheme were initiated in September 1964, with 107 Entry being the first Technician Apprentice entry, 201 Entry being the first of the Craft Apprentice entries, and 301 Entry being the first of the Administrative Apprentice entries. A one-year scheme for mechanic apprentices was also subsequently introduced (the 400 series entry apprentices). Alumni It is estimated that as many as forty percent of the "Trenchard Brats" or the "Poacher's Brats" (as the Cranwell Apprentices were called because of their Lincolnshire connection), achieved commissioned rank, and a considerable number achieved Air rank. Graduates of this scheme include several former officers of Air rank, including Air Commodore Sir Frank Whittle, father of the jet engine, Marshal of the Royal Air Force Sir Keith Williamson, Air Chief Marshal Sir Mike Armitage, Air Marshal Sir Graham Miller, and Air Marshal Cliff Spink The Brats' alumni association, a registered charity, is called the RAF Halton Apprentices Association (RAFHAA), or Old Haltonians. It publishes a magazine called The Haltonian three times a year. A triennial reunion for Brats is organised by the association. RAF Halton has its own memorial to the brats opposite Kermode Hall, very close to St George's Church, which contains stained glass windows commemorating the 40,000 or so apprentices who were trained there. Brats are also remembered at the Halton Grove, which is part of the National Memorial Arboretum, Alrewas, Staffordshire.
