Author McDonald was director of the Space Shuttle Solid Rocket Motor Project at the time the Challenger space shuttle exploded. He also was one of the individuals who warned NASA against the launch, and one of few on the inside who never signed a confidentiality agreement. This is McDonald's insider story, a retelling of the tragedy direct from the Launch Control Center. A skilled engineer and executive, McDonald was the only individual singled out for retribution by NASA and Morton Thiokol, his employer and the manufacturer of Challenger's solid rocket boosters. This is an even-handed take on an American aerospace tragedy. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
