Pearl Harbor survivor Ira Schab returned to the Hawaii naval base 82 years after Japan’s bombing propelled the U.S. into World War II. Schab was one of just five survivors at a remembrance ceremony for the more than 2,300 servicemen killed on Dec. 7, 1941. Six men had been expected, but one of the increasingly frail men wasn't able to attend. The aging pool of Pearl Harbor survivors has been rapidly shrinking. There is now one crew member of the USS Arizona still living. The U.S. Department of Veterans Affairs doesn’t have statistics for how many Pearl Harbor survivors are alive.
