Nagasaki has marked the 80th anniversary of the U.S. atomic attack on the southern city in Japan. Survivors are determined to make their hometown the last place on Earth hit by a nuclear bomb.

At 11:02 a.m. Aug. 9, 1945, from 1,650 feet above Nagasaki, “Fat Man,” an atomic bomb fueled with Hanford site plutonium, was dropped.
