Pearl Harbor survivor James Dewitt was among more than 5,000 people who observed a moment of silence at 7:55 a.m. Wednesday. It was exactly 70 years after the beginning of the military strike by Imperial Japanese forces on Pearl Harbor. And it was 70 years since Dewitt had been back.

He was surprised to see how much the harbor and Oahu Island had changed.

"First thing I recognized is where the battleship Utah was. Other than that, nothing seems the same," Dewitt said.
