Parsons thought while arming "Little Boy": "I knew the Japs were in for it, but I felt no particular emotion about it.”Little Boy" was created using uranium-235, a radioactive isotope of uranium. This uranium-235 atomic bomb, a product of $2 billion of research, had never been tested. Nor had any atomic bomb yet been dropped from a plane. Some scientists and politicians pushed for not warning Japan of the bombing in order to save face in case the bomb malfunctioned.

There had been four cities chosen as possible targets: Hiroshima, Kokura, Nagasaki, and Niigata. The cities were chosen because they had been relatively untouched during the war. The Target Committee wanted the first bomb to be "sufficiently spectacular for the importance of the weapon to be...
