Tsutomu Yamaguchi has died at the age of 93. He was in Hiroshima when the atomic bomb was dropped. After suffering radiation burns, he heard that there was a train leaving to the town where his family lived, so he crossed a river that had no bridge by crawling across hundreds of bloated, floating dead bodies to the other side where the train station was, and headed back home . . . to Nagasaki, where the second atomic bomb was dropped days later. He is the only officialy recognized survivor of both bombings.
