Mushroom Cloud Over Nagasaki, Lieutenant Charles Levy, 1945 Three days after an atomic bomb nicknamed Little Boy obliterated Hiroshima, Japan, U.S. forces dropped an even more powerful weapon dubbed Fat Man on Nagasaki. The explosion shot up a 45,000-foot-high column of radioactive dust and debris. “We saw this big plume climbing up, up into the sky,” recalled Lieutenant Charles Levy, the bombardier, who was knocked over by the blow from the 20-kiloton weapon. “It was purple, red, white, all colors—something like boiling coffee. It looked alive.” The officer then shot 16 photographs of the new weapon’s awful power as it yanked the life out of some 80,000 people in the city on the Urakami River. Six days later, the two bombs forced Emperor Hirohito to announce Japan’s unconditional surrender in World War II. Officials censored photos of the bomb’s devastation, but Levy’s image—the only one to show the full scale of the mushroom cloud from the air—was circulated widely. The effect shaped American opinion in favor of the nuclear bomb, leading the nation to celebrate the atomic age and proving, yet again, that history is written by the victors.
