X-15: The World's Fastest Rocket Plane and the Pilots Who Ushered in the Space Age, Zenith Press, 2014, 8.25" x 10.25" inches, 144 pages.
by John Anderson and Richard Passman
In X-15, the exciting story of the X-15—the iconic rocket plane of the Cold War space race—is recounted by John Anderson, Curator of Aerodynamics at NASM, and Museum volunteer Richard Passman, who was Chief Aerodynamicist for the Bell X-2. This experimental space plane was on the cutting edge of hypersonic aerodynamics, and its winged reentry from space foreshadowed the development of the Space Shuttle decades later. Launched from the wing of a modified B-52 bomber—again foretelling a concept that would be used decades later, in this case by SpaceShipOne and SpaceShipTwo—the ship rocketed higher and faster than any manned aircraft of the time. Designed to approach seven times the speed of sound, it was the first hypersonic aircraft ever created and was engineered to function both in the Earth’s atmosphere and at the edge of space. Illustrated with period NASA and USAF photographs, as well as exclusive Smithsonian photography of the first of three X-15s built, X-15 captures the risks and dangers of the X-15 program as Anderson and Passman follow the test pilots (including Neil Armstrong) who pushed the very limits of their piloting skills to master groundbreaking experimental technology. Even with the fatal crash of the third X-15, the overall success of the program helped pave the way for NASA to continue to the Moon.
