It wsa only 9 years after the Wright Brothers made their historic flight when a young American motorcycle maker opened a new chapter in the history of flight. In 1942, Glenn Curtiss achieved an airborne speed record of 46.5 miles per hour, and the quest for speed was on. QUEST FOR SPEED traces man's relentless push to soar higher and faster. It relives dramatic breakthroughs, like Chuck Yeager's 1947 flight in the Bell X-1 that shattered the sound barrier at 670 m.p.h. And it features some of the world's most advanced aircraft, including the SR-21 Blackbird US Reconnaissance plane that cruises at three times the speed of sound, at altitudes above eighty thousand feet. QUEST FOR SPEED is the story of a rare breed of adventurers willing to push remarkable machine to their limit -- and sometimes beyond.
