During the Second World War, the RAF employed Special Duties pilots and aircrew on operations across a wide range of extraordinary flying. In many instances, selected and trained crews flew specific sorties, seeking out small targets of utmost importance to the war effort. Rare and previously unexplained duties that incorporate 'siren raids' into Germany and the maintaining of radio contact with agents in occupied France provide accounts that have rarely been evidenced. Some of these operations were filmed by cameramen and RAF Special Duties includes an account, revealed by one such pilot who accompanied the de Havilland Mosquitos which attacked the Gestapo headquarters in Copenhagen. In many instances, 'flying logbooks' and official documentation support this exceptionally well-researched book, which includes accounts from Radar Counter Measures, Tactical Reconnaissance, 'Special Window Forces' and encompasses aircraft diversely spread between heavy bombers to the light aircraft engaged in spotting targets in Italy.
