A Popular Mechanics Best BookWinner of the American Institute of Aeronautics and Astronautics Gardner-Lasser Aerospace History Literature AwardFinalist for the American Astronautical Society's Eugene M. Emme Astronautical Literature Award"We all watched in shock and disbelief when Challenger was lost. Probably no one felt more disappointment and regret than Allan McDonald, who had warned us not to launch that day. His story tells of loss, grief, and the eventual rebuilding and recovery."--Robert "Hoot" Gibson, former Space Shuttle pilot and commander "A major contribution to a difficult episode in the history of human spaceflight."--Roger D. Launius, Division of Space History, Smithsonian Institution "There have been many accounts of the circumstances surrounding the loss of the Space Shuttle Challenger on 28 January 1986, but few, if any, give as much of an insider's view as this book."--Quest "McDonald argues convincingly that the Challenger accident need not have happened, had his warnings been heeded; therein lies the tragedy."--Space Policy "A major contribution to the literature of the management of technology as well as to the history of the space program."--Choice "Whistle-blowing yet rigorous and fair-minded book."--Spaceflight "An even-handed take on an American aerospace tragedy."--Book News "Recounts the decision to launch Challenger, the investigation of the accident, and the return of the shuttle to space flight. McDonald's book is, like the shuttle itself, a massive, complex, and fascinating work."--Florida Historical Quarterly Allan J. McDonald retired as vice president and technical director for advanced technology programs at ATK Thiokol Propulsion in 2001. He was the director of the Space Shuttle Solid Rocket Motor Project at the time of the Challenger accident and, later, vice president of engineering for space operations during the redesign and requalification of the solid rocket motors.
