Seventy years ago, the B-29 Enola Gay, piloted by Paul Tibbets, Jr., dropped an atomic bomb, Little Boy, on the Japanese city of Hiroshima. The blast and ensuing radiation killed an estimated 150,000 people. Though the devastation from the bombing was astounding, it did not bring American’s war with Japan or World War II to an immediate end. Three days later, the United States dropped another atomic bomb, Fat Man, on Nagasaki, and the Empire of Japan’s leaders finally capitulated.
