This is a book describing a survival expedition of two U.S. navy pilots who sailed a rubber raft across the Pacific testing new survival techniques. The story is both a story of adventure, and one giving details of what it takes to survive in the open ocean.The two pilots departed San Francisco with no water and six pounds of food arriving in Hawaii 56 days later. Both had dropped in weight from 186lb to 128lb. It was only at the end of the trip that the Navy acknowledged they were “an official navy project”.
