The former launch commentator "e;offers a personal-and sometimes painful-look back at one of the darkest chapters in US human spaceflight"e; (Space.com). On January 28, 1986, the space shuttle Challenger launched from the Kennedy Space Center in Florida. Seventy-three seconds after launch, the fiery breach of a solid motor joint caused a rupture of the propellant tanks, and a stunned nation watched as flames engulfed the craft, killing all seven crew members on board. It was Hugh Harris, "e;the voice of launch control,"e; whom audiences across the country heard counting down to lift-off on that fateful day. With over fifty years of experience with NASA's missions, Harris presents the story of the Challenger tragedy as only an insider can. With by-the-second accounts of the spacecraft's launch and a comprehensive overview of the ensuing investigation, Harris gives readers a behind-the-scenes look at the devastating accident that grounded the shuttle fleet for over two years. This book tells the whole story of the Challenger's tragic legacy.
