Tomorrow, August 6th, is the 75th anniversary of the first-ever use of a nuclear weapon in war, when the U.S. dropped an atomic bomb on Hiroshima, Japan.

At the controls of the B-29 called the Enola Gay was a young pilot named Paul Tibbetts.

After the war, Tibbetts returned to a very humble and private life in Ohio.

As the 1990s were drawing to a close, Chicago Tribune columnist and author Bob Greene was finally, after years of trying, to get PaulTibbetts to talk about his history-making flight.
