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)
Bockscar
The failure to drop the Fat Man at the precise bomb aim point caused the atomic blast to be confined to the Urakami Valley. As a consequence, a major portion of the city was protected by the intervening hills, but even so, the bomb was dropped over the city's industrial valley midway between the Mitsubishi Steel and Arms Works in the south and the Mitsubishi-Urakami Ordnance Works in the north. An estimated 35,000 people were killed and 60,000 injured during the bombing at Nagasaki. Of those killed, 23,200–28,200 were Japanese munitions workers, 2,000 were Korean slave laborers, and 150 were Japanese soldiers.
