On August 6th, 1945 during WWII, a 9,000 pound Uranium 235 bomb was loaded on a modified B-29 bomber named Enola Gay after it’s arrival on the Pacific Island of Tinian. The plane dropped the bomb also known as “Little Boy” by parachute at 8:15 a.m. which exploded 2000 feet above Hiroshima destroying four to five square miles of the city. Just before the dropping of the A-bomb, the U.S. Air Force dropped pamphlets in Hiroshima warning them about the bomb.
Hiroshima was manufacturing center that had 350,000 people located about 500 miles from Tokyo, Japan.
When the atomic bomb was dropped on Hiroshima, the explosion was so tremendous that it permanently burned shadows and objects into the ground. The explosion wiped out ninety percent of the city and killed about 80,000 people. Tens of thousands more died later on due to radiation exposure.
The cause of Pearl Harbor was because the Japanese planned a war to conquer Burma, Malaya, East Indies, and the Philippines. And they didn’t want the U.S. Pacific fleet in Pearl Harbor to disrupt their plans so they decided to attack Pearl Harbor, a U.S. Base as a precaution in a surprise air attack.
