100-year-old Pearl Harbor survivor recalls chaos during Japanese bombing in 1941

Bob Fernandez thought he'd go dancing and see the world when he joined the U.S. Navy as a 17-year-old high school student in August 1941.

Four months later, he found himself shaking from explosions and passing ammunition to artillery crews so his ship's guns could return fire on Japanese planes bombing Pearl Harbor, a Navy base in Hawaii.

"When those things go off like that, we didn't know what's what," said Fernandez, who is now 100. "We didn't even know we were in a war."
