Sixty-five years ago today, on August 6th 1945, the first atomic bomb used against a population was detonated at 0815 in the morning above the city of Hiroshima Japan.
The bomb had a nickname; it was “Little Boy”. Little boy used the fizzile Uranium isotope ‘U235’ to produce an enormous release of energy. Despite the devastation it caused it is estimated that only 1.38% of the ‘U235’ was used in the detonation.
70,000 people were dead by 0816. Tens of thousands more would die as a result of the bombing over the coming weeks.
The B29 that delivered Little Boy to Hiroshima was selected just after mother’s day 1945 (before the plane had left the assembly line) by its pilot Col Paul Tibbets as the plane that would deliver this weapon to Japan. He named the plane after his mother “Enola Gay Tibbets”.
