Book excerpt: When his electronic warfare plane--call sign Bat 21--was shot down on 2 April 1972, fifty-three-year-old Air Force navigator Iceal “Gene” Hambleton parachuted into the middle of a North Vietnamese invasion force and set off the biggest and most controversial air rescue effort of the Vietnam War. Now, after twenty-five years of official secrecy, the story of that dangerous and costly rescue is revealed for the first time by a decorated Air Force pilot and Vietnam veteran. Involving personnel from all services, including the Coast Guard, the unorthodox rescue operation claimed the lives of eleven soldiers and airmen, destroyed or damaged several aircraft, and put hundreds of airmen, a secret commando unit, and a South Vietnamese infantry division at risk. The book also examines the thorny debates arising from an operation that balanced one man’s life against mounting U.S. and South Vietnamese casualties and material losses, the operation’s impact on one of the most critical battles of the war, and the role played by search and rescue as America disengaged from that war.
