Shigeko Sasamori was 13 years old on August 6, 1945. At 8:15 AM she was working with her junior high classmates clearing the streets of Hiroshima, Japan. She looked up into the clear blue sky when she heard a plane flying overhead and saw something white dropping to the earth. Shigeko was less than a mile from the center of the explosion caused by the world's first atomic bomb. Somehow, Shigeko survived. Also in this episode: photographer David Spear.
