Initially, recruiting was limited to officers and NCOs only, recruiting for the original RAF companies being undertaken by the AAF. However, with the coming of the Second World War, airwomen were to join the ranks and, by mid 1943, there were 182,000 women serving in the WAAF, in all the RAF trade groups. In common with the AAF, the women's force became less 'auxiliary' as the war went on; but on the outbreak of war, the WAAF consisted of 234 officers and 1500 airwomen, all of whom could be considered pre-war volunteers in the true auxiliary mould.
