The RAF Pocket Book issued in 1937, and amended to 1939, is in many ways the RAF equivalent of Staff Duties in the Field, issued to ground forces. It covers administration, discipline and signals. Of particular importance to airmen it also deals with air navigation, meteorology, airmanship and many other important topics, including liaison with the Navy and the Army. It also covers explosives and weapons in 17 chapters which give a very detailed picture of how the RAF thought and worked in the years leading up to the Second World War. A rare find, this book is recommended to everyone.
