December 7 is Pearl Harbor Day, marking the surprise attack 80 years ago that propelled the U.S. into World War II. More than 2400 Americans were killed, nearly half of them crew members of the U.S.S. Arizona. Donald Stratton, of Colorado Springs, was on the ship that day and survived. Stratton died last year at the age of 97. He shared his experience at Pearl Harbor in the memoir, "All the Gallant Men." Nathan spoke with Stratton's co-author, Ken Gire, in 2016.
