Foreword by Dr. Roger D. Launius, Former NASA Chief Historian For the past 75 years, the U.S. government has invested significant time and money into advanced aerospace research, as evidenced by its many experimental X-plane aircraft and rockets. NASA's X-Planes asks a simple question: What have we gained from it all? To answer this question, the authors provide a comprehensive overview of the X-plane’s long history, from the 1946 X-1 to the modern X-60. The chapters describe not just the technological evolution of these models, but also the wider story of politics, federal budgets, and inter-agency rivalries surrounding them. The book is organized into two sections, with the first covering the operational X-planes that symbolized the Cold War struggle between the U.S. and the U.S.S.R, and the second section surveying post-Cold War aircraft and spacecraft. Featuring dozens of original illustrations of X-plane cross-sections, in-flight profiles, close-ups, and more, this book will educate general readers and specialists alike.

Trace the historical beginnings of the aircraft that pushed aviation-performance levels to new heights, many of which were developed into the great operational fighters and bombers of yesterday and today. See photos of pioneers of aviation such as the Bell XP-59A (America's first jet fighter). Get the pilot's story of test-flying an XB-70 Valkyrie. See the prototypes for tomorrow's Lockheed F-22.

A fascinating review of the record-breaking experimental aircraft of the future currently being built and tested by the U.S. Air Force and NASA. The X-Planes, drawing on recently declassified information, is the first comprehensive book on the experimental aircraft. 335 photos and 30 scale drawings.

This illustrated WWII history reveals the full range of experimental military aircraft that the Third Reich nearly flew into combat. From jet planes and high-altitude aircraft to radar-equipped fighters configured to deliver chemical weapons, numerous secret Luftwaffe planes reached prototype stage during the Second World War. Had these innovative aircraft made it into combat, the course of the war could have gone very differently. Renowned aviation expert Manfred Griehl explores these projects through an informative and fascinating selection of images, including numerous wartime photographs. Despite the Allied authorities' ban on research, countless aircraft were designed and tested by the Luftwaffe and German manufacturers before World War II. The research went ahead at secret evaluation sites in Germany, Switzerland, Sweden and the USSR. Though this work continued after the outbreak of war, many projects were never completed, often because the developers simply ran out of time. This definitive guide reveals the remarkable range of planes that the Third Reich failed to complete.

The revolutionary X-15 remains the fastest manned aircraft ever to fly. Built in the two decades following World War II, it was the most successful of the high-speed X-planes. The only recently broken 'sound barrier' was smashed completely by the X-15, which could hit Mach 6.7 and soar to altitudes above 350,000ft, beyond the edge of space. Several pilots qualified as astronauts by flying above 50 miles altitude in the X-15, including Neil Armstrong, the first man on the Moon. The three X-15s made 199 flights, testing new technologies and techniques which greatly eased America's entry into manned space travel, and made the Apollo missions and Space Shuttle viable propositions. With historical photographs and stunning digital artwork, this is the story of arguably the greatest of the X-Planes.

Exotic research aircraft designed, built, and flown in Europe in the two decades following World War II were the foreign equivalent of the legendary American X-Planes. Many of these advanced aircraft flown by test pilots such as Peter Twiss and Andre Turcat captured speed and altitude records previously held by their American counterparts. Some of today's most famous and successful aircraft were influenced by advanced technologies first tested and flown on European X-Planes. A significant number of aviation "firsts" occurred at secluded flight test facilities located in England, France, and Germany. The world's first jet airliner (1948), first jet transport with rear-mounted engines (1956), first VTOL jet fighter (1964), and first supersonic airliner (1969) were all developed in Europe utilizing technological advances pioneered by these rare and highly advanced X-Planes. Unpublished photographs, detailed appendix, and stories of these historic aircraft combine to produce an in-depth look at these secret aircraft.
