Don Charlwood, a wartime navigator with the Royal Australian Air Force, was posted in the winter of 1942 to 103 Squadron at Elsham Wolds, Lincolnshire. Here he tells the breath-taking true story of a wartime bomber crew facing the hazards of bombing strongly defended targets such as Essen, Dusseldorf and Berlin, and writes sympathetically and understandingly of the hopes and fears of the crews as squadron losses mounted.
