On Dec. 7, 1941, Japanese forces launched a surprise attack on the U.S. Naval base at Pearl Harbor, Hawaii. By the time the attack was over, 2,402 were killed and another 1,282 were wounded.

More than 70 years after the attack, the wounds of Pearl Harbor are still fresh for many survivors. Jack Colby was there that day and says even though he doesn’t like to look back, he thinks every American needs to remember those who died.
