In 1978, the first group of space shuttle astronauts was introduced to the world -- twenty-nine men and six women who would carry NASA through the most tumultuous years of the space shuttle program. Among them was USAF Colonel Mike Mullane, who, in his memoir <I>Riding Rockets,</i> strips the heroic veneer from the astronaut corps and paints them as they are -- human. <P> Mullane's tales of arrested development among military flyboys working with feminist pioneers and post-doc scientists are sometimes bawdy, often comical, and always entertaining. He vividly portrays every aspect of the astronaut experience, from telling a female technician which urine-collection condom size is a fit to hearing "Taps" played over a friend's grave. He is also brutally honest in his criticism of a NASA leadership whose bungling would precipitate the Challenger disaster -- killing four members of his group. A hilarious, heartfelt story of life in all its fateful uncertainty, <I>Riding Rockets</i> will resonate long after the call of "Wheel stop."
