American astronauts may have lived the dream of seeing space, but they never would have made it without Guenter Wendt. In The Unbroken Chain, this unsung hero tells his story, and he's got the right stuff. Wendt, who immigrated to the United States from Germany in 1949, got a job as a mechanical engineer for McDonnell Aircraft that launched his space career. He eventually became the man who supervised preparations for every mission from the Mercury program through the early shuttle flights. He was the last person the astronauts would see before they closed the hatch, and he became something of a legend at NASA. The Unbroken Chain features Wendt's accounts of his career highlights, good and bad, as well as behind-the scenes revelations about missions and personalities. Three sections of great photos accompany the text, and best of all, the accompanying CD-ROM features a tour of Cape Canaveral hosted by Wendt himself. A must-have for space buffs, and a great accompaniment to the NASA Mission Reports series, also from Apogee Books. --Therese Littleton
