Lancasters of No. 83 Squadron Pathfinder Force as they climb out over the east coast of England en-route for Peenemunde on the warm summer evening of 17th August, 1943. Brilliantly navigated in darkness right over the target, the masterbomber’s aircraft, seen in the forefront of Robert Taylor\'s painting, made nine dangerous passes over the target, directing operations. During the next 55 minutes Hitler’s secret weapon establishment was almost totally destroyed by the bomber crews that followed his directions.
