Amazon.co.uk Review
The term "rocket plane" now conjures images from vintage pulp sci-fi. But in a programme that began years before Gagarin and Shepard launched the space race, NASA's X-15 research vehicle ambitiously arched towards the fringes of space, expanding the speed-and-altitude envelope of manned flight like none before it. In the course of a 199 flights over a decade, the X-15 became the first manned aircraft to rocket past Mach 4, 5 and 6; soared some 67 miles above the Earth (earning a handful of its dozen pilots their Astronaut wings, though ironically not Neil Armstrong, later first to set foot on the Moon); and crucially gathered the cornerstone data that enabled the Space Shuttle's return from space a couple decades later. Authors/historians/archivists Dennis Jenkins and Tony Landis have produced nothing short of a landmark history of the X-15's pioneering effort, which, they argue, was the most productive flight-test programme ever)--the first truly comprehensive chronicle of every phase of its pre-history, development and often perilous journeys (USAF pilot Mike Adams was killed on one of the craft's final flights, while several others suffered injuries in mishaps). Fueled by an obvious passion for their subject, the authors skillfully boil a daunting body of history, technical data and personalities down into an eminently accessible chronicle of technical achievement and human bravery. In doing so they've drawn on a wealth of documentary materials and interviews from pilots, NASA and USAF sources and key personnel from North American Aviation, the X-15's manufacturer. Pilots Scott Crossfield and Bill Dana (the first and last to fly the spaceplane, respectively) have also contributed written introductions.

Synopsis
The X-15 is the only vehicle so far that has been flown by a pilot (rather than a computer) into space and back, routinely surviving re-entry temperatures. The X-15 was also the fastest airplane ever built, over twice as fast as the SR-71 Blackbird! It was also the highest-flying aircraft ever to take to the skies, in it five Air Force pilots became astronauts taking the X-15 into near-space. Nineteen years before the Space Shuttle, the small, black, rocket-powered, bullet-shaped X-15 showed it was possible to fly into and out of space. There had never been anything like the X-15; it had a million-horsepower engine and could fly twice as fast as a rifle bullet. The X-15 set records that stood for years. Hypersonic is the most extensively researched history of the X-15 programme yet produced. Written with the co-operation of surviving X-15 pilots as well as many other programme principals it is based on six years of research in Air Force, NASA, and North American archives. The book describes the flight programme in detail,. This includes the most authoritative flight log ever assembled; derived from the original flight data recordings.
The book also describes each of the experiments that were flown aboard the X-15 late in its career when it became the workhorse of the space programme, carrying such things as startrackers destined for the Apollo programme and missile detection systems that would later be sent into orbit on satellites.
