Book excerpt: In 1961, pilot Robert M. White flew a hypersonic rocket-powered airplane six times faster than the speed of sound and higher than 300,000 feet above the Earth's surface. This is his story. Tracing his childhood on the rough streets of Manhattan during the Depression, his years as a pilot and POW during World War II, his service in Korea and Vietnam and his rise as an experimental test pilot in the Air Force, this autobiography is a testament to the role of persistence and excellence in the life of a man whose aeronautical feats are now legend. It is the portrait of an extraordinary man in pursuit of the American dream and a glimpse into a remarkable time in America's aviation history.
