A mushroom cloud over Hiroshima following the explosion of an atomic bomb
The bomb was nicknamed "Little Boy" and was thought to have the explosive force of 20,000 tonnes of TNT
Colonel Paul Tibbets, a 30-year-old colonel from Illinois, led the mission to drop the atomic bomb on Japan
The Enola Gay, the plane which dropped the bomb, was named in tribute to Col Tibbets' mother
The final target was decided less than an hour before the bomb was dropped. The good weather conditions over Hiroshima sealed the city's fate
On detonation, the temperature at the burst-point of the bomb was several million degrees. Thousands of people on the ground were killed or injured instantly.
