End of World War II in Asia
Second, and more powerful plutonium implosion atomic bomb, Fat Man, is dropped on Nagasaki from a different "Silverplate" B-29 named "Bockscar", flown by Maj. Charles Sweeney (Atomic bombing of Nagasaki)
Nagasaki Atomic Bomb Museum
Within the museum is a history of the city before the bomb was dropped. The hypocenter of the explosion was the Urakami district, which was a traditionally rustic and isolated suburb. However, the population soared after the 1920s when the district was chosen as the site for munitions factories. An industrial zone was quickly created. Additionally, the Urakami district was home to the Nagasaki Medical College. When the bomb was dropped at 11:02 A.M. on August 9, 1945, the 20 neighborhoods within a one-kilometer radius of the hypocenter were completely destroyed by the heat flash and blast winds generated by the explosion. They were then reduced to ashes by the fires which followed. Within 2 km of the hypocenter, roughly 80% of the houses collapsed and burned. When the smoke cleared, the area was strewn with corpses.
