This picture is tame by comparison.
James Bradley, the author of Flags of Our Fathers, is currently writing a book called Flyboys. It will be out soon (this fall, I think) - the subject matter is the fate of a group of airmen who were beheaded and cannibalized after having to ditch near Chi Chi Jima.
(Incidentally, former President George H. W. Bush could have suffered the same, if not for his rescue in the waters just off the island.)
