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)
Niigata (city)
In 1945, near the end of the war, Niigata was one of four cities, together with Hiroshima, Kokura, and Nagasaki, picked as targets for the atomic bomb if Japan did not surrender. The governor of Niigata Prefecture ordered the people to evacuate as rumors of an impending bombing spread, and the city was completely deserted for days. Poor weather conditions and its distance from B-29 bases in the Mariana Islands meant that it was removed from the list of targets during deliberations; Nagasaki was bombed instead.
