James Bradley - Flyboys: a true story of courage - Little Brown and Company, 2009
“Flyboys tells the story of nine American World War II pilots shot down over the remote island of Chichi Jima. One pilot, George H. W. Bush, was rescued by a submarine. They other eight were captured by the Japanese, and disappeared. A military inquiry after the war was labeled top secret and sealed the story of the fate of these men from even their families. With painstaking research, James Bradley has uncovered the truth behind what happened to these men.
Flyboys also tells the history of U.S. and Japanese relations that set the stage for the atrocities that happened during the war, including the POWs on Chichi Jima…” (souce: http://www.reviewsofbooks.com/flyboys/)
