Once the decision was made, the decision of when and where the bomb was to be dropped shifted to General Carl Spaatz. A committee chose to drop the bomb on Hiroshima based on three main factors: Hiroshima was a very industrial city, had a military base, and had not yet been bombed, making it a good target to display the destructive power of the US's new super bomb. The bomb was dropped at 8:15 am on August 6, 1945 from a B-29 bomber. The bomb fell from the Enola Gay (the name of the bomber) with a parachute and the bomb exploded several hundred feet above the ground. "A bright light filled the plane," wrote Lt. Col. Paul Tibbets, the pilot of the Enola Gay. "We turned back to look at Hiroshima. The city was hidden by that awful cloud...boiling up, mushrooming." For a moment, no one spoke. Then everyone was talking. "Look at that! Look at that! Look at that!" exclaimed the co-pilot, Robert Lewis while pounding on Tibbets' shoulder. Lewis said he could taste atomic fission; it tasted like lead. Then he turned away to write in his journal. "My God," he asked himself, "what have we done?" The bomb destroyed houses and buildings within a 1.5 mile radius. It was actually the winds created by the bomb which caused the most damage. The true damage however would not be realized for years to come. The long term effects of the bomb were discovered to be: genetic problems, malformed babies, retardations, radiation sickness, and mental trauma. The total death toll of "Little Boy" was about 200,000. After the bomb was dropped Truman once again warned Japan of the devastation which was to come if they did not surrender.
