We used a state of the art targeting machine aboard the Enola Gay to target hiroshima and drop the bomb. We dropped the bomb on august 6th 1945

“he combined heat and blast pulverized everything in the explosion’s immediate vicinity, generated fires that burned almost 4.4 square miles completely out, and immediately killed some 70,000 people (the death toll passed 100,000 by the end of the year). A second bomb, dropped on Nagasaki on August 9, killed between 35,000 and 40,000 people, injured a like number, and devastated 1.8 square miles.”
