Nagasaki
On August 9, 1945, three days after the bombing on Hiroshima, Bockscar, another American B-29, dropped Fat Man onto the industrial city of Nagasaki. Bockscar had a failed fuel pump so the crew headed for their secondary target to drop Fat Man. Fat Man was a 10,000 pound plutonium bomb that was built to produce a 22-kiloton blast. However, Nagasaki rested in narrow valleys between mountains and reduced the blast effect of the bomb and destruction radius to 2.6 square miles. Approximately 75,000 people were killed in the attack. Six days later, Japan surrendered.
