The next chapter in Zamperini’s life almost ended it. He joined the Army Air Corps in 1941 and was assigned to a B-24 liberator bomber nicknamed “Superman.” In a bombing of the Nauru Pacific Atoll, Zamperini’s plane was attacked by a Japanese zero squadron. The crew managed to return the bomber to its base, where the mechanic calculated 594 bullet holes. Zamperini, pilot Russell Allen Phillips and tail gunner Francis McNamara is one of the other B-24 crew members. The Green Hornet began a rescue mission on May 27, 1943, looking for a shot down. pilot. Both port engines on the green bumblebee failed, and it crashed into the ocean. Of the 11 crew members, only Zamperini, Phillips and McNamara survived. Their only emergency food was a chocolate bar, and McNamara was panicked. They drifted for 47 days, survived by the seabirds that fell on the rafters, the occasional fish and the rainwater they collected. McNamara died of hunger. The other two men lost half their weight when a Japanese patrol boat near the Marshall Islands was picked up.
