During the Second World War, RAF Lancaster bombers took the conflict into the very heart of Hitler's Third Reich, and flew some of the most daring operations of the war. Surprisingly, of the 7,377 Lancasters built only two survive today, one in Britain and one in Canada. Produced with the full cooperation of the RAF's Battle of Britain Memorial Flight, and illustrated with incredible photographs, this book gives a rare and fascinating insight into how the Lancaster bomber was constructed, flown and operated, together details of how it is serviced and maintained.
