The detonation of an atomic bomb in Hiroshima, Japan on August 6, 1945 was one of the most horrific events in the history of the world. Equivalent to 20,000 kilotons of TNT, the atomic bomb known as 'Little Boy' was launched from the B-29 bomber, Enola Gay. The bomb destroyed two thirds of Hiroshima, an estimated 70,000 civilians dying immediately followed by the death of an additional 70,000 as a result of radiation poisoning over the course of the following five years. All that remained of those closest to the blast were shadows imprinted on buildings.
