Guenter Wendt's autobiography, "The Unbroken Chain", is a ground-shaking, fumes in your nostrils, documentary of the glory days of manned spaceflight. It is described in graphic detail by the one man who worked side-by-side with every astronaut that left the Cape bound for space. Because of his unique perspective from the launch pad, his story is filled with important accounts and anecdotes, many of which have never been published until now. From the altitude chamber, to the simulators, to the white room itself, follow the "Unbroken Chain" to the moon and beyond. There is no story like it.
