The key scientists of the Manhattan Project. The pilot who navigated Enola Gay over its target. The man who broke the news to Truman that the bomb had been dropped. And the citizens of Hiroshima who somehow survived to see their city obliterated. These are the stories of August 6, 1945, the day that launched the atomic age, told by the people who were there. Through their heroic, harrowing, and heartbreaking accounts, we relive the tragic day that hastened the end of a war and changed the world forever.
