Hiroshima is bombed, August 6, 1945
Forty-three seconds after its release, at an altitude of 1,890 feet, the bomb’s proximity fuse detonates. One-millionth of a second later, the heat on the ground below spikes to 6,000 degrees. The people of Hiroshima begin to incinerate. Death comes so quickly that nerve endings do not have time to react to pain. Three milliseconds later, the sky erupts into a fireball 300 yards wide. Day turns into night as the mushroom cloud blots out the sun. Within seconds, 70,000 people are dead. Three months later, the death toll rises to 130, 000 due to infection from burns and radiation poisoning.
