The Complete Book of the SR-71 Blackbird: The Illustrated Profile of Every Aircraft, Crew, and Breakthrough of the World's Fastest Stealth Jet

At the height of the Cold War in 1964, President Johnson announced a new aircraft dedicated to strategic reconnaissance. The Lockheed SR-71 Blackbird spy plane flew more than three-and-a-half times the speed of sound--so fast that no other aircraft could catch it. Above 80,000 feet, its pilots had to wear full-pressure flight suits similar to what was used aboard the space shuttle.
