Shrewsbury, 1st ed., 1997. 272 pp., photo-plates + maps. D.j., 24 x 16cm. Small bump to top o/w FINE. The author made an outstanding contribution to the history of the RAF. Although written in the form of an autobiography, these memoirs are more a commentary on the author's colleagues in the RAF, and their way of life. He describes his training in Egypt with only the bare minimum of navigation facilities, and his subsequent highly challenging operations flying through east and west Africa. In 1936, after qualifying to specialise in air navigation, he was posted to the Air Ministry to write Air Navigation, for which he is best remembered. It became the classic text book published in 1941 which turned thousands of wartime civilians into RAF aircrew. An instant success, it was translated into many languages and used at all RAF training schools. In November 1941 he commanded a squadron of Whitleys in the Battle of the Atlantic. He was then appointed Chief Navigation Officer at Coastal Command HQ, where his operational experiences led him to initiate significant changes in the role and status of navigators. His story reveals rarely recorded insights into the comradeship which characterised the RAF, and also highlights the important contributions that he made to its operational efficiency.
