The tension-filled careers of the Mercury Seven, a handful of elite fighter pilots selected as America's first astronauts, is traced in this account of the dreams and nightmares of the early days of the U.S. manned space program. A behind-the-scenes look at the competitive and often arrogant atmosphere of the initiative—including details on the struggles of deciding whether to send chimpanzees or humans to space and the conflicts between NASA engineers and astronauts—is included along with an account of the program's moments of humor, from recurrent "gotcha" training session pranks to the round of drinks that a dubious answer to the question Are you a turtle? could entail. While most of these men eventually made it to space and even the moon, their lives as a part of NASA continued long after. The story of their work with motivational programs such as the Smithsonian's National Air and Space Museum, U.S. Astronaut Hall of Fame, U.S. Space Camp, and the U.S. Space & Rocket Center is also included.
