Nagasaki

On August 9, 1945, atomic bomb Fat Man's primary target was Kokura, not Nagasaki. Smoke and clouds obscured the target through 50 minutes and three failed runs. With fuel critically low, the B-29 Bockscar diverted to Nagasaki, its secondary target.

Yamaguchi Tsutomu survived both Atomic bombs dropped on Hiroshima and Nagasaki. After the first blast, he returned to Nagasaki and went to work. His boss scolded him — "a single bomb can't destroy a city" — and at that exact moment, the second atomic bomb detonated.
