Color image of fireball at the moment Nagasaki atomic bomb exploded

This aerial photograph was one of the first color films by the movies at the moment just after Nagasaki Atomic Bomb exploded from the hypocenter in Nagasaki City. The Plutonium Atomic Bomb called "Fat Man", just after the rupture, the center of the heat-ball reached up to several million degrees at extremely super-high temperature. Nagasaki Atomic Bomb instantly bulged a fireball with a diameter of about 280 m and a surface temperature of about 5000 degrees. It had been storming out the intense hot windstorm and violent radiation into Nagasaki city. It formed a mushroom cloud covering Nagasaki City entirely.
