===On August 6, 1945, the United States used a massive, atomic weapon against Hiroshima, Japan. This atomic bomb, the equivalent of 20,000 tons of TNT, flattened the city, killing tens of thousands of civilians. While Japan was still trying to comprehend this devastation three days later, the United States struck again, this time, on Nagasaki.===

===Hiroshima At 2:45 a.m. on Monday, August 6, 1945, a B-29 bomber, [|the Enola Gay], took off from Tinian, a North Pacific island in the Marianas, 1,500 miles south of Japan. The twelve-man crew (picture) were on board to make sure this secret mission went smoothly. Colonel Paul Tibbets, the pilot, nicknamed the B-29 the "Enola Gay" after his mother.===

===Just before take-off, the plane's nickname was painted on its side. The Enola Gay was a B-29 Superfortress (aircraft 44-86292), part of the 509th Composite Group. In order to carry such a heavy load as an atomic bomb, the Enola Gay was modified: new propellers, stronger engines, and faster opening bomb bay doors. (Only fifteen B-29s underwent this modification.) Even though it had been modified, the plane still had to use the full runway to gain the necessary speed, thus it did not lift off until very near the water's edge.===

===1 The Enola Gay was escorted by two other bombers that carried cameras and a variety of measuring devices. Three other planes had left earlier in order to ascertain the weather conditions over the possible targets. On a hook in the ceiling of the plane, hung the ten-foot atomic bomb, [|"Little Boy."] Navy Captain William S. Parsons ("Deak"), chief of the Ordnance Division in the "Manhattan Project," was the Enola Gay's weaponeer. Since Parsons had been instrumental in the development of the bomb, he was now responsible for arming the bomb while in-flight.===

===2 "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 (Kyoto was the first choice until it was removed from the list by Secretary of War Henry L. Stimson). 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 internationally recognized when publicity on it was released."===

===3 On August 6, 1945, the first choice target, Hiroshima, was having clear weather. At 8:15 a.m. (local time), the Enola Gay's door sprang open and dropped "Little Boy." The bomb exploded 1,900 feet above the city and only missed the target, the Aioi Bridge, by approximately 800 feet. Staff Sergeant George Caron, the tail gunner, described what he saw: "The mushroom cloud itself was a spectacular sight, a bubbling mass of purple-gray smoke and you could see it had a red core in it and everything was burning inside. . . . It looked like lava or molasses covering a whole city. . . ."===

===4 The cloud is estimated to have reached a height of 40,000 feet. Captain Robert Lewis, the co-pilot, stated, "Where we had seen a clear city two minutes before, we could no longer see the city. We could see smoke and fires creeping up the sides of the mountains."===

===5 Two-thirds of [|Hiroshima] was destroyed. Within three miles of the explosion, 60,000 of the 90,000 buildings were demolished. Clay roof tiles had melted together. Shadows had imprinted on buildings and other hard surfaces. Metal and stone had melted. Unlike many other bombing raids, the goal for this raid had not been a military installation but rather an entire city. The atomic bomb that exploded over Hiroshima killed civilian women and children in addition to soldiers. Hiroshima's population has been estimated at 350,000; approximately 70,000 died immediately from the explosion and another 70,000 died from radiation within five years. A survivor described the damage to people: "The appearance of people was . . . well, they all had skin blackened by burns. . . . They had no hair because their hair was burned, and at a glance you couldn't tell whether you were looking at them from in front or in back. . . . They held their arms bent [forward] like this . . . and their skin - not only on their hands, but on their faces and bodies too - hung down. . . . If there had been only one or two such people . . . perhaps I would not have had such a strong impression. But wherever I walked I met these people. . . . Many of them died along the road - I can still picture them in my mind -- like walking ghosts."===
