Atomic Bombing of Hiroshima
On August 6, 1945, an American B-29 bomber named the Enola Gay, left the island of Tinian for Hiroshima, Japan. This mission was piloted by Col. Paul Tibbets. Hiroshima was chosen as the primary target since it had remained largely untouched by the bombing raids and the bomb's effects could be clearly measured.
The U-235 gun-type bomb, named Little Boy, exploded at 8:16:02 a.m. In an instant 80,000 to 140,000 people were killed and 100,000 more were seriously injured.
