Commander Pauline Gower MBE was given the task of organising the women's section of the ATA. The first eight women pilots were accepted into service on 1 January 1940, initially only cleared to fly Tiger Moths from their base in Hatfield. They were: Joan Hughes, Margaret Cunnison, Mona Friedlander, Rosemary Rees, Marion Wilberforce, Margaret Fairweather, Gabrielle Patterson, and Winifred Crossley Fair. Overall during World War II there were 166 women pilots, one in eight of all ATA pilots, and they volunteered from Britain, Canada, Australia, New Zealand, South Africa, the United States, the Netherlands and Poland. From Argentina and Chile came Maureen Dunlop and Margot Duhalde. Fifteen of these women lost their lives in the air, including the British pioneer aviator Amy Johnson.
