A comprehensive history with descriptions of the world's most significant aircraft employed as "eyes in the sky." For almost as long as there has been sustained heavier-than-air human flight, airplanes have been used to help gather information about our adversaries. Less than a decade after the Wright Brothers flew at Kitty Hawk, Italian pilots were keeping tabs on Turkish foes in North Africa. Today, aircraft with specialized designs and sensory equipment still cruise the skies over foreign lands and seas, trying to spy out secrets. Spyplanes is the comprehensive history of manned spyplanes, beginning with those Italian airplanes puttering above the North African desert and continuing through every major world conflict to culminate with jets cruising at supersonic speeds 85,000 feet above the Earth's surface. Nearly seventy-five aircraft from eight nations are profiled, pictured, and accompanied by a specification box. Included are purpose-built spyplanes, as well as legendary fighters and bombers that have been retrofitted for the purpose over the years. In addition, the authors feature preliminary chapters discussing the history of aerial surveillance and a host of sidebars that explore considerations such as spyplanes in military doctrine, events such as the Cuban missile crisis, the downing of Francis Gary Powers' U-2, the 1992 Open Skies Treaty, and the USAF's current Big Safari program. Spyplanes also expands beyond fixed-wing planes to include notable helicopters that have been outfitted for recon and surveillance. From prop-driven to jet-powered aircraft, this is the ultimate history and reference source to those "eyes in the skies" that have added mind-bending technologies, as well as an element of intrigue, to military aviation for more than a century.
