During the Second World War, RAF Lancaster bombers took the war into the very heart of Hitler's Third Reich, pounding its ciaties and industrial centres with more that 600,000 tons of bombs. lancasters flew some of the most daring bomber operation of the war including the intrepid daylight attack on the MAN diesel engine factory in Bavaria in 1942, the legendary dams raid in 1943 and the attacks on the German battleship Tirpitz in 1944. Surprisingly of the 7,377 Lancasters built, only tow survive today in an airworthy condition. One in Canada and one in Britain. This manual gives a rare and fascinating insight into how the Lancaster is constructed, how it is flown and operated and the all important details of how it is serviced and maintained to keep it airworthy.
