ALL HE COULD SEE, IN EVERY DIRECTION, WAS WATER. It was June 23, 1943. Somewhere on the endless expanse of the Pacific Ocean, Army Air Forces bombardier and Olympic runner Louie Zamperini lay across a small raft, drifting westward. Slumped alongside him was a sergeant, one of his plane’s gunners. On a separate raft, tethered to the first, lay another crewman, a gash zigzagging across his forehead. Their bodies, burned by the sun and stained yellow from the raft dye, had winnowed down to skeletons. Sharks glided in lazy loops around them, dragging their backs along the rafts, waiting.
