Confidential and Secret preparation and training of Hiroshima Atomic Bomb at the air force of Utah state

A preliminary implementation was carried out with a simulated "Little Boy" for testing to install it in "Enola Gay" B-29 before dropping the Hiroshima Atomic Bomb. In May 1945 a secret experiment and a refurbishment loading of the B - 29 was carried out at Wendover Air Force Base in the desert at the western end of the state of Utah in the United States of America. "Enola Gay", which loaded the atomic bomb "Little Boy" from Wendover Air Force Base, flew to Tinian Island. In September 1944 the new base contraction and the secret atomic bombing unit were confidentially organized under the lieutenant General, Leslie Richard Groves Jr. Air Force brigadier General, Paul Warfield Tibbets Jr. was appointed aboard Enola Gay, which would drop the Hiroshima Atomic Bomb. Immediately after arriving at Tinian Island, the Wendover Air Force Base had disappeared in July 1944.

Color image of fireball at the moment Nagasaki atomic bomb exploded

This aerial photograph was one of the first color films by the movies at the moment just after Nagasaki Atomic Bomb exploded from the hypocenter in Nagasaki City. The Plutonium Atomic Bomb called "Fat Man", just after the rupture, the center of the heat-ball reached up to several million degrees at extremely super-high temperature. Nagasaki Atomic Bomb instantly bulged a fireball with a diameter of about 280 m and a surface temperature of about 5000 degrees. It had been storming out the intense hot windstorm and violent radiation into Nagasaki city. It formed a mushroom cloud covering Nagasaki City entirely.

Hiroshima Atomic bomb completely destroyed and burned in Hiroshima city after one hours

   About one hour after the explosion of the Hiroshima Atomic Bomb on August 6, 1945 at 8:15 AM, the majority of Hiroshima City burst into a lot of flames. On Hiroshima City just under the Hiroshima Atomic Bomb, Mushroom cloud had occurred. Huge smoke clouds was covered with extensive fires. Due to the violent blast of Hiroshima Atomic Bomb and the thermal radiation, most of the houses without buildings were completely destroyed and burned down. Many citizens were burned down and died by total destruction or burned without escape and breathing from the fires at the surroundings. Most Japanese houses were made of wood, with the exception of reinforced concrete buildings involving complete destruction and burnout.

The Mushroom cloud was photographed at the earliest from the ground by Nagasaki Atomic Bomb

   It was a mushroom cloud which was taken a photograph at 11:17AM about 15 minutes after 11:02 AM on 9 August 1945 when the Nagasaki atomic bomb exploded. The photo was first taken from the Kawanami shipyard in Koyagi remote island which was about 10 km south-southwest from the hypocenter. The Mushroom clouds taken from the ground in the atomic bomb had been shot at the earliest. "Boxes Cars" dropping the Nagasaki Atomic Bomb was retreating toward the sky above Koyagi island. The isolated island of Koyagi was included Nagasaki Peninsula in the landfill of the 1960s.

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.

 

Afflicted aerial photograph on the disaster just after the Nagasaki Atomic Bomb

   The Nagasaki Atomic Bomb exploded on August 9, 1945, 11:02 am, about 500 meters above 171 Matsuyama-cho, Nagasaki City. This was an aerial photograph of the situation damaged immediately after the Nagasaki Atomic Bomb. The hypocenter "Ground Zero" was about 2.5 km upstream of the Uragami River from the upper left corner of the aerial photograph. At field-battle order No.17, the original aiming point 114016 was on the Nigiwai bridge on the way of Nakashima River. For that purpose, this had been an aerial photograph focusing mainly on the Nagasaki bay area and the aiming point of Nakasaki Atomic Bomb. The periphery of the hypocenter "Ground Zero"  at the upper left corner was completely ashamed in a moment. Nagasaki city was surrounded by mountains in the east and west, while the disaster area completely destroyed the houses reached about 2.5 km south east to Nagasaki Port, extended more than about 2 km of Hiroshima Atomic Bomb. The damage suffered into the semi-rupture ranged from the hypocenter to about 4 km southward.

Aerial photographs on the day following Hiroshima Atomic Bomb showed all center destruction.

   The next day after August 6, 1945 when the Hiroshima Atomic Bomb was dropped and exploded, USA military aircrafts for reconnaissance photos  flew on August 7, 1945. That took aerial photographs of the exposure to Atomic Bomb against Hiroshima City from the altitude of about 9000 m. That shot and scouted the aerial photographs after Hiroshima Atomic Bomb similar to the mosaic aerial photographs before the Hiroshima Atomic Bomb. It bursted at about 600 m above the real hypocenter of the Shima hospital about 300 m southeast of Aiyoi bridge supposed to be the hypocenter. The Circumference within about 2000m from the hypocenter was almost completely destroyed and burned down. Especially the above had been destroyed all around the Temma River to the west branched from Ota River at Hiroshima Castle, the main Ota downstream west to the Motoyasugawa river where branched to the east from Aiyoibashi Bridge.
