Seventy years after the attacks on Pearl Harbor, one San Diego man can still remember the sound of bullets whizzing past him underwater as he dove for his life.
After his ship was hit and capsized, he jumped into the water, diving deep under the surface and hanging onto coral to avoid being hit.
"You could hear the bullets hitting the water and they'd go about 3 feet and then they'd start sinking,” Ruffato said.
“Now I didn't know bullets were hot when they came out of a gun - but they're hot - cause you could hear them sizzle as they went by your head down there."
USS Utah was hit by torpedoes and a five hundred pound bomb.
Mass confusion followed.
Sailors in rooms where torpedoes hit tried to get above deck while other sailors rushed down to their bombing quarters below.
Ruffato went topside but the Japanese were attacking with machine guns. When the attack relented, he swam to shore.
He shot at Japanese planes with an old rifle - then drove to the other side of Ford Island for medical supplies.
It almost cost him his life.
Passing the airfield, he saw two planes he thought were coming in to land.
"I thought 'why are they turning their lights on' - but they weren't turning their lights on - they were machine gunning my truck," he recalled.
Ruffato eventually made it back with the supplies but he lost many fellow sailors that day.
One whispered his last words to him.
For Ruffato, surviving Pearl Harbor put life in perspective.
"I get kind of down and I say ‘Buck up Bob, you could have been killed in Pearl Harbor,’" he said.
Ruffato went on to serve in nine major engagements including the Battle of Guadalcanal.
He and his wife of 40 years raised six children here in San Diego. He now lives on Mission Bay and stays active in the veterans’ community.
