DROPPING THE ATOMIC BOMBWhat Were the First Effects of Dropping the Atomic Bomb?●On August 6, 1945, a B-29 bomber named the Enola Gay took off from an airbase on the Pacific island of Tinian. Tucked into its bomb bay was an 8,900-pound atomic bomb nicknamed Little Boy. At 8:15 am Japanese time, the bomber dropped Little Boy over thecity of Hiroshima, a city in western Japan. Three days later, a second atomic bomb, calledFat Man, was dropped over the city of Nagasaki.●Hiroshima had been chosen because it was a military command center as well as communication, troop assembly, and supply point for the Japanese army. It had not suffered previous bomb damage, and it was also located in a level area where resulting damage could be easily assessed. The city had a few buildings made of reinforced concrete, but most of the structures were made of wood. They were weaker, and much of the city was highly vulnerable to fire.●Nagasaki was a military port city and shipbuilding center. It was not as effective a target as Hiroshima to the U.S. military because it had suffered previous bomb damage, and it would be difficult to tell (from a scientific standpoint) how much damage the atomic bomb would cause. The original target had been the city of Kokura, but bad weather forced the bomber plane to choose the second potential target, Nagasaki, instead.
