The first biography of the man who created the way we look for airmen downed in combat behind enemy lines

Pardoe presents the complex story of Frederick Zinn, who created the techniques still in use to determine the final fate of airmen missing in action. His lasting contribution to warfare was a combination of his methodology for locating the remains of missing pilots and his innovation of imprinting all aircraft parts with the same serial number so that if a wreck was located, the crewman could be identified.
