Today, August 6, is the 69th anniversary of the atomic bombing of Hiroshima. It happened at 08:15 Japan time. The Enola Gay, a Boeing B-29 Superfortress bomber, released a bomb named Little Boy containing 64 kg (141 lb) of uranium-235 over the city. It took Little Boy 44.4 seconds to drop from 31,000 feet (9,400 m) to a height of about 1,900 feet (580 m) where it detonated.
4.7 square miles (12 km2) of the city was destroyed. Within seconds, 75,000 people were killed or fatally injured. 65% of the casualties nine years of age and younger. Beneath the epicenter of the explosion temperatures were hot enough to melt concrete and steel. 69% of the city’s buildings were destroyed. The bomb started fires that spread rapidly through wood and paper homes.
The blast released nearly 200 different kinds of radioactive isotopes (nuclear fission particles of uranium and plutonium that escaped fission). These particles and other materials irradiated by the bomb’s neutrons were carried high into the atmosphere.
The mix of massive amounts of airborne irradiated materials merged with heat and thermal currents from the firestorms caused it to rain within an hour of the bombing. Fallout particles mixed with carbon residue from fires created the deadly “black rain” reported by many eyewitnesses.
On that day, Hiromu Morishita was 14 years old and in the ninth grade. He survived. He became a calligrapher and teacher. He was president of the Senior High School Teachers’ Society and the Hiroshima Peace Education Institute in Japan. He wrote a poem:
Here, something happened that shouldn’t have.
Here now, something irreparable continues.
Here tomorrow, signs of everyone’s destruction
Don’t watch with one eye.
Don’t watch with your arm or with your head.
With the heart of one who endures despair.
