Mushroom cloud completely covering Hiroshima City one hour after the Hiroshima Atomic Bomb

　Hiroshima Atomic Bomb was a mushroom cloud taken an aerial photograph  from the US military reconnaissance plane about one hour after explosion at Hiroshima City on August 6, 1945 at 8:15 AM. It reconnoitered the disaster at about 80 km southeast from the hypocenter. From 30 seconds after the explosion of the atomic bomb, it was turning over to observe the damage situation toward Hiroshima City. Although at about 30,000 feet (9.14 km) height also it fled over the sky, the mushroom cloud swelled and rose higher than that. With gray clouds from the purple flame, the center part exploded a red mass and the mushroom clouds expanded out. Hiroshima City was completely swallowed by pyroclastic flow like a torrents of lava. Narrowly outside of the corner of Kure City at the southeast end, the fog ranges from Kurashi to Etajima in the Seto Inland Sea, but the other northeast to Hiroshima City was completely covered with mushroom clouds.
