The second bomb is designed for Korura but there is cloud, so the plane is diverted to Nagasaki. Nagasaki's population drops in one split-second from 422,000 to 383,000, thus 39,000 were killed, over 25,000 were injured. Including those who died from radioactive materials causing cancer, the total number of residents killed is believed to be at least 100,000.
