This is the story of one of the RAF's oldest and most distinguished heavy bomber squadrons in WW2, although an outline history of the unit since it was formed in WW1 and its post-war history are included. It was the first operational Stirling Squadron, the RAF's first four engine heavy bomber, and flew the first long-distance raids into the heart of Nazi Germany. This new aircraft was a break-through in terms of range and bomb load but it was also an aircraft that suffered from many teething problems. Long-distance navigation was also a black art before the introduction of radio navigation systems and the squadron suffered many fatalities in those early wartime years. Having gained expertise in their task the unit was the first to be equipped with the H2S navigational aid and eventually became one of the original elite Pathfinder squadrons. When the Lancaster came into service the Squadron re-equipped and joined 8 Group and had the dubious reputation of suffering the third greatest loss of aircraft in Bomber Command. It did however participate in more Lancaster raids than any other 8 Group squadron. Read Less
