The XB-70 Valkyrie was an aircraft ahead of its time. Equipped with drooping wingtips, and designed with one of the highest lift-to-drag ratios in aviation history, the XB-70 challenged the known concepts of the flight envelope and demanded extraordinary developments in engineering and construction. The test program produced promising results, including a Mach 3 flight in May of 1966. Yet after a disastrous collision later that year resulted in the loss of one of two prototypes, the Valkyrie program was curtailed. The remaining craft was retired in 1969. Originally printed by NASA and the Air Force in the 1960's, this Flight Operating Handbook taught pilots everything they needed to know before entering the cockpit. Classified "Restricted", the manual was recently declassified and is here reprinted in book form. This affordable facsimile has been slightly reformatted. Care has been taken however to preserve the integrity of the text.

Of the many futuristic military aircraft concepts created in the 1950s the North American XB-70 still stands out as the most awe-inspiring. With its huge, white partially-folding delta wing, its fuselage resembling a striking cobra and its extraordinary performance, it was one of the foremost technological achievements of the 20th Century. A strategic bomber built to outrun any Soviet fighter jet, it could reach Mach 3 with a full nuclear payload - as fast as the legendary SR-71 Blackbird but more than three times the size. However, its role as a nuclear bomber was limited after the introduction of Intercontinental Ballistic Missiles, and defence cuts eventually led to the project being scrapped in the mid-1960s. The Valkyrie had a brief, costly decade of life but it proved the continuing value of developing manned bombers. However, almost half a century after the XB-70 its predecessor, the B-52, continues in service. Using full colour artwork and rigorous analysis, this is the complete story of the ultimate US Cold War military X-plane.

From the most important leaders and the most courageous victories to the earliest machines of flight and the most advanced Stealth technology, this book presents a fascinating look at 50 turbulent years of Air Force history. Three 8-page photo inserts, one in color.

Selected by Choice Magazine as an Outstanding Academic Title for 2003 The National Advisory Committee for Aeronautics—forerunner of today's NASA—emerged in 1915, when airplanes were curiosities made of wood and canvas and held together with yards of baling wire. At the time an unusual example of government intrusion (and foresight, given the importance of aviation to national military concerns), the committee oversaw the development of wind tunnels, metal fabrication, propeller design, and powerful new high-speed aircraft during the 1920s and '30s. In this richly illustrated account, acclaimed historian of aviation Roger E. Bilstein combines the story of NACA and NASA to provide a fresh look at the agencies, the problems they faced, and the hard work as well as inventive genius of the men and women who found the solutions. NACA research during World War II led to critical advances in U.S. fighter and bomber design and, Bilstein explains, contributed to engineering standards for helicopters. After 1945 the agency's test pilots experimented with jet-powered aircraft, testing both human and technical limits in trying to break the so-called "sound barrier." In October 1958, when the launch of the Soviet Sputnik signaled the beginning of the space race, NACA formed the nucleus of the new National Aeronautics and Space Agency. The new agency's efforts to meet President Kennedy's challenge—safely landing a man on the Moon and returning him to Earth before the end of the 1960s—is one of the great adventure stories of all time. Bilstein goes on to describe NASA's recent planetary and extraplanetary exploration, as well as its less well-known research into the future of aeronautical design.
