Novato, 1st ed., 2000. Vi + 322 pp., photo-ills. D.j., 24 x 16cm. FINE. At the beginning of the Cold War the United States conducted a secret air war against the Soviet Union. As the struggle began, these pilots were the pathfinders who flew into the unknown, seeking information on how the USSR might be preparing an attack on the West. Flown by a handful of U.S. and allied aircrews, these photographic and electronic intelligence-gathering missions were unknown to the world at large. To tell this story the author draws on previously top secret Soviet and U.S. documents, as well as the recollections of participants on both sides.
