This book details the stories of Challenger's missions from the points of view of the astronauts, engineers, and scientists who flew and knew her and the managers, technicians, and ground personnel who designed her and nursed her from humble beginnings as a structural test article into one of the most capable Shuttles in NASA's service. Challenger veterans, including Gordon Fullerton and Vance Brand, describe their experiences and the differences between Challenger and her sister ships. The development of Challenger herself is explored in detail, including her design, development, construction, and preparation for missions.
