From the first American orbiting satellite, to Neil Armstrong, and Buzz Aldrin's historical walk on the Moon, virtually every major achievement in American Space history was made possible by a Rocketdyne engine. And, that record has stood true for over forty years, as today the Space Shuttle program continues to rely on engines designed and built by Rocketdyne. This book is the story behind that unprecedented accomplishment. It is the chronicle of success of one team of rocket pioneers who propelled the American space program from trailing the Soviet Union in the 1950s and early 1960s into today's position of leadership in space. It is a story of heroes and even a few villains, but mostly it is a story of triumphant success in the human venture into space. For the early history of rocketry up through the work of Dr Robert Goddard in the early 1940s, Kraemer referenced the history books of T A Heppenheimer and Frank Winter. The rest of the book is a chronicle of both the author's own memories and experiences as a member of the Rocketdyne team, as well as those of other key members of this elite group, including: Bill Brennan, George Sutton, Bill Cecka, Doug Hege, Bill Ezell, Tom Myers, John Tormey, Paul Castenholz, Sam Iacobellis, Ed Monteath, Steve Domokos, Stan Gunn, Willy Wilhelm, Bob Biggs, Ted Benham, and Vince Wheelcok. This book is a true testament to the human spirit - and to a dedicated and determined team of aerospace engineers who launched a nation into Space.
