From the back cover:

The RAF’s most successful heavy bomber of World War 2, the Avro Lancaster formed the backbone of Bomber Command during the large-scale night bombing campaign against occupied Europe. In this, the first of two volumes on the British bomber icon of World War 2, noted English aviation historian Jon Lake recounts the early daylight raids, the first ‘thousand bomber’ raids on Germany and the epic ‘Dambusters’ mission of 16/17 May 1943 by No 617 Sqn, as well as myriad other sorties to numerous German targets in 1942-43. This volume contains more than 100 photographs, 30 all-new colour profiles by leading aviation artist Chris Davey and specially commissioned scale drawings of the Lancaster B I/II by Mark Styling.
