"SKY SPY" is the enthralling autobiography of Ray Holmes, who joined the RAF Volunteer Reserve in 1936 and graduated from pupil to fully fledged fighter pilot, flying instructor and photo-reconnaissance pilot during the Second World War. His was a varied war, flying many different tupes of aircraft in a wide assortment of situations. Most notable, however, were his sorties in the Hurricane and later, the Spitfire. In the Hurricane, he was the first fighter pilot to shoot down a German bomber over London during the Battle of Britain. He flew sweeps over France, protecting convoys, and was sent out to Murmansk for five months to teach the Russians how to fly Hurricanes. On his return from Soviet Russia he became involved in photographic reconnaissance, photographing targets far into German from six miles high in his specially equipped Spitfire.
