title: Atomic bombings of Hiroshima and Nagasaki text: Atomic bombings of Hiroshima and Nagasaki During the final stage of World War II, the United States detonated two nuclear weapons over the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively. The United States dropped the bombs after obtaining the consent of the United Kingdom, as required by the Quebec Agreement. The two bombings killed 129,000–226,000 people, most of whom were civilians. They remain the only use of nuclear weapons in the history of warfare. In the final year of the war, the Allies prepared for what was anticipated to be a very costly invasion title: Atomic bombings of Hiroshima and Nagasaki text: month later. In 1949, one of the authors of the letter, Luis Alvarez, met with Sagane and signed the letter. At 11:01, a last-minute break in the clouds over Nagasaki allowed "Bockscar"s bombardier, Captain Kermit Beahan, to visually sight the target as ordered. The Fat Man weapon, containing a core of about of plutonium, was dropped over the city's industrial valley. It exploded 47 seconds later at , above a tennis court, halfway between the Mitsubishi Steel and Arms Works in the south and the Nagasaki Arsenal in the north. This was nearly northwest of the planned hypocenter; the blast title: Atomic bombings of Hiroshima and Nagasaki text: of atomic bombs, and the 509th Composite Group of the United States Army Air Forces (USAAF) was equipped with the specialized Silverplate version of the Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands. Orders for atomic bombs to be used on four Japanese cities were issued on July 25. On August 6, one of its B-29s dropped a Little Boy uranium gun-type bomb on Hiroshima. Three days later, on August 9, a Fat Man plutonium implosion-type bomb was dropped by another B-29 on Nagasaki. The bombs immediately devastated their targets. Over the next two to title: Atomic bombings of Hiroshima and Nagasaki text: dropping an atomic bomb on Hiroshima, the Oppenheimer-led Scientific Panel of the Interim Committee decided against a demonstration bomb and against a special leaflet warning. Those decisions were implemented because of the uncertainty of a successful detonation and also because of the wish to maximize shock in the leadership. No warning was given to Hiroshima that a new and much more destructive bomb was going to be dropped. Various sources gave conflicting information about when the last leaflets were dropped on Hiroshima prior to the atomic bomb. Robert Jay Lifton wrote that it was July 27, and Theodore H. McNelly title: Atomic bombings of Hiroshima and Nagasaki text: 07:09. At 08:09, Tibbets started his bomb run and handed control over to his bombardier, Major Thomas Ferebee. The release at 08:15 (Hiroshima time) went as planned, and the Little Boy containing about of uranium-235 took 44.4 seconds to fall from the aircraft flying at about to a detonation height of about above the city. "Enola Gay" traveled before it felt the shock waves from the blast. Due to crosswind, the bomb missed the aiming point, the Aioi Bridge, by approximately and detonated directly over Shima Surgical Clinic. It released the equivalent energy of , ± 2 kt. The weapon
