Description
Joe Walker as X-15 test pilot, with the second X-15 aircraft. US test pilot Joseph Albert 'Joe' Walker (1921-1966) made 24 flights in the X-15, including several record-breaking ones. The X-15 was a rocket-powered research aircraft designed to investigate flight at hypersonic speeds. Three X-15s flew a total of 199 missions between 1959 and 1968. The X-15 was carried into the air by a converted B-52 bomber and released at high altitude. The pilot then ignited the X-15's rocket motor. It was the first plane to reach the edge of outer space and set records for the fastest manned aircraft (7,274 kilometres per hour, or Mach 6.72). Photographed in 1961.
