On August 6, 1945, at 9:15 Tokyo time, the "Enola Gay", a large aircraft controlled by Paul W. Tibbets, dropped "Little Boy", an atomic bomb, on Hiroshima, in Japan. In a short period of time, half of the city completely disappeared from the map. At least 60,000 people were exterminated or missing, and approximately 100,000 people were killed and 140,000 seriously injured. Many more people were left homeless by the bomb. In the explosion, thousands of people died as quickly as lightning. The city was incredibly devastated in a horrible way. Of its 90,000 buildings, more than 67% of the structures were demolished. Another bomb was assembled on the island of Tinian on August 6. or Kokura or Nagasaki. It was originally supposed to be on Kokura, but Nagaskaki was the backup target. Three days after Hiroshima, the B-29 "Bockscar" bomber piloted by Sweeney reached the skies above Kokura on the morning of August 9. He abandoned the primary objective because the sky was just covered with pitch-black smoke and changed course for Nagasaki. At 11 a.m., the "Fat Man" bomb exploded over the northern industrial district 1,800 feet above the city to achieve the maximum effect of the feared atomic bomb. Shortly thereafter the buildings collapsed. The electrical systems were shorted. A wave of secondary fires occurred, killing more people. Flash burns from primary heat waves caused most of the casualties among natives. Others were burned after their homes caught fire, resulting in many house fires. Flying debris has caused many injuries, as have tornadoes. A windstorm followed the detonation at Hi...... middle of paper ......ring of World War IILos Alamos was approved as the site for the main scientific laboratory of the atomic bomb on November 25, 1942 by Leslie R. Groves and Robert Oppenheimer. They were given the code name Project Y. A bomb, using plutonium, was successfully tested on July 16, 1945, at a site 120 miles (193 km) south of Albuquerque, New Mexico. The first atomic bomb to be used in warfare used uranium. It was dropped by the United States on Hiroshima, Japan on August 6, 1945. 3 days later, Nagasaki was severely bombed. http://avalon.law.yale.edu/subject_menus/mpmenu.asp http://www.factmonster.com/spot/hiroshima1.html http://www.atomcentral.com/hiroshima-nagasaki.aspx http:/ /www.cnduk.org/campaigns/global-abolition/hiroshima-a-nagasaki http://www.history.com/topics/pearl-harbor http://www.history.com/topics/pearl-harbor
