As many know, the atomic bomb has been used only twice in warfare. The first was at Hiroshima. A uranium bomb nicknamed “Little Boy” (despite weighing in at over four and a half tons) was dropped on Hiroshima August 6, 1945. The Aioi Bridge, one of 81 bridges connecting the seven-branched delta of the Ota River, was the target; ground zero was set at 1,980 feet. At 0815 hours, the bomb was dropped from the Enola Gay. It missed by only 800 feet. At 0816 hours, in an instant, 66,000 people were killed and 69,000 injured by a 10-kiloton atomic explosion.
