Diary of a Bomb Aimer is historian Campbell Muirhead's personal account of flying with twelve Squadron bombers over Germany during World War II. Campbell Muirhead kept a meticulous diary of his wartime RAF service from the day that he set forth to train as a pilot in Canada and the USA in 1942 to the end of his wartime service with twelve Squadron Bomber Command. He was unable to pass the flying course and decided to retrain as a bomber because he wished to become operational as soon as possible. The book is particularly emotive as Muirhead reveals in the common parlance of those wartime days, truly reflecting the emotions, fears and feelings of those caught up in that mighty conflict. His diligent observations of life in the RAF from joining-up, crossing the Atlantic, training in the New World bring back wartime life as it really was. His descriptions of the perils of flying on bombing raids deep into the heart of Germany reveal the many different aspects of life in a front-line squadron in a way that can only be told by one who was there.
