Air power has always been linked closely to science and technology. The very reality of flight depended upon a technical innovation. Unlike other services, where machines merely support the mission, technology is for the Air Force at the very heart of its existence as an institution. As a consequence, the USAF and its predecessor organizations have always recognized the singular importance of science to their survival. This book describes and analyzes the methodologies and conclusions of the five main science and technology forecasts undertaken by the Air Force since before its birth as an independent service.
