Hiroshima atomic bomb with highly concentrated uranium 235 exposed the super destructive energy by nuclear fission chain reaction

　USA invested $ 2 billion in the Manhattan plan to complete the atomic bomb before the end of the Pacific War and concluded it from September 1942. It needed slightly 500 million dollars for the electromagnetic separation method and 500 million dollars for the gas diffusion method to produce highly enrich uranium 235, for the  explosive material of the Hiroshima atomic bomb. Uranium 235 was low concentrated from gas diffusion method until March 1945. 50 kg of highly enriched uranium 235 could be supplied by the electromagnetic separation method in time before August 1945. 

 Compared to the uranium process, the explosive device of Hiroshima atomic bomb could be easily developed and produced. The uranium 235 were separated into a shell-like part and a ring-shaped part. After they crashed by TNT, Neutrons were generated and the super destructive energy could be exposed by the nuclear fission and chain reaction within uranium 235.

A development and implementation leader into Hiroshima Atomic Bomb for the first time in human history

  They were a substantial development and implementation leader of the first atomic bomb in human history. The person on the right is Julius Robert Oppenheimer, Ph.D. who was a developer. The person on the left was, Leslie Richard Groves, the executive. Leo Szilard and Albert Einstein on August 2nd, 1939 had appealed Atomic Bomb Crisis by Nazi German to President Roosevelt, who commanded the beginning of the atomic bomb development by the Manhattan plan. From September 1942, Globus was appointed for the executive director and implemented confidentially the Manhattan plan of Atomic Bomb within the Army, which was invested a budget of 2.2 billion dollars. On March, 1943 Oppenheimer was appointed the Director at Los Alamos National Laboratory and led the development of the atomic bomb. On July 16, 1945, Oppenheimer succeeded the Trinity Atomic Bomb experiment and on July 23, Groves ordered the atomic bomb into Hiroshima City.

Both deaths by Hiroshima and Nagasaki Atomic Bomb corresponded to that by Air raids throughout Japan by B-29

   President Franklin Roosevelt boosted the Military aircraft in the January 14, 1939 of Union massage. On May 16, 1940, he appealed the 50,000 aircrafts per a year extraordinarily. A long-range strategic bomber was completed in June 1943 which was developed B-29 with a radius of 3,219 km and an altitude of 9,144 m by 3 billion dollars. From September 1942, he spent $ 2 billion into the Manhattan project, which was the development of the atomic bomb. Japan military had been already annihilated and destroyed from Solomon Islands in August 1942. The B - 29 developed an incendiary bomb that burns people and buildings, bombed it and burned the whole of Japan through aerial bombardment. B-29 intensively bombed the urban areas of Japan intensively from the Yahata Air raid on June 16, 1944. After less alarm to many citizens, they ran back to the air defense shelter but they were delayed. The primary dead citizens (excluding missing) were about 225,000 at the Air raid of the mainland (excluding Okinawa), about 150,000 at Hiroshima Atomic Bomb, about 74,000 at Nagasaki Atomic Bomb, totaling about 449,000. The two bases of the Hiroshima Atomic Bomb and the Nagasaki Bomb corresponded to the Air raids deaths throughout Japan by B-29.

Imperial Headquarter announced the atomic bomb as a new bomb and Japan should already win in justice.

   Imperial Headquarter announced at 15 PM on August 7 that B-29 used a new bomb on Hiroshima City on August 6, 1945. 

1) Hiroshima City suffered considerable damage by attacks of a few enemy B-29. 2) Details of the enemies was now being investigated, such as those using new bombs in the attack.
  In the nationwide Yomiuri Newspaper in Japan, the new bomb was a hollow explosion with a parachute, which caused house collapses and fires. "Justice in Japan does not crush, shame the enemy on the cruelty" After about 8 o'clock on 6, Aug, a few B-29 entered the sky above Hiroshima City and dropped a few bombs. As a result, a considerable number of houses were collapsed and fires were broke out in downtown areas. This new type of bomb used by the enemy was what burst on the way of falling with a parachute. Regarding the power of the new bomb, the authorities would be promptly conducting the investigation, so it should be clearly found but disrespecting was prohibited.
   The Newsletter declared "Western countries are often banned as "humanitarian enemies" by bringing together this inhuman cruelty while referring to humanitarianism with daily religious beliefs of Christianity. Their evil masks are completely removed and it should be said that Japan already won in justice".

"Enola Gay" bomber drove and dropped an atomic bomb to Hiroshima City for the first time in human history

The B-29 "Enola Gay" loaded the atomic bomb "Little Boy" for the first time in human history and dropped on Hiroshima City, Aug. 6th, 1945. The captain "Tibbets", Paul Warfield Tibbets, Jr. named the bomber "Enola Gay" which he quote from his mother's name and was painted at the boarding gate ahead. In order to keep the atom bombs secret, the B-29 was changed the aircraft number on the vertical tail to "R" with a large circle and the recognition number to "86"on the airframe. The exhibition of real "Enola Gay" with the history about atomic bomb disasters at the Smithsonian Museum in 1995 was abandoned due to the violent opposition of the veterans. The aircraft is displayed with sharp guard at the annex.

The Mushroom cloud became huge still after 20 minutes passed since the Hiroshima atomic bomb exploded

   The Atomic Bomb was dropped in Hiroshima City, which exploded at 8:15AM on August 15, 1945. The Mushroom clouds are generated from the hypocenter of the Atomic Bomb and it covered almost Hiroshima City. The Mushroom clouds had been also enormous still after 20 minutes have passed since the explosion of the Atomic Bomb. The Mushroom cloud was photographed from the ground of Kaitaichi Town where existed near the Hiroshima City. It was caught from Kaichi Town about 10 km east from Hiroshima city. Kaitaichi Town, where was mostly settled from the sea and surrounded by three low mountains. Kaitaichi Town was an intersection point between Hiroshima and Kure military bases.

Protest of Smithsonian exhibition about Hiroshima Atomic Bomb and removal of the disaster history

     This shows a duplicate of a replica of "Little Boy" which was a uranium type  of the atomic bomb dropped in Hiroshima City. The replica was reproduced the appearance and color from the atomic bomb material to the details of the prototype. In the center of the "Little Boy", an orange safety plug protected the safety device. 

   The replica of "Little Boy" is exhibited at the Smithsonian Air and Space Museum located at the side of Dulles Airport. Enola Gay's B-29 bomber that dropped "Little Boy" was also displayed in the annex of the museum. In 1995, the Veteran organization of the US military protested the exhibition of "Enola Gay" B-29, and the exhibition was torn down. In 2003 the disaster and historical documents caused the Hiroshiam Atomic Bomb about the legitimacy of the American military were deleted and exhibited in the annex. 

   The B-29 bomber of the Box Car that dropped the Nagasaki Atomic Bomb is displayed with the Nagasaki Atomic Bomb "Fat Man" at the Dayton Air Force Museum in Ohio sate.

News Papers only reported the atomic bomb as only large powerful bomb

　The New York Times was a great influential newspaper in the United States, which posted crossword puzzles during the Second World War at 1942. It was a liberal newspaper approved any intervention by US government and asserted the justification of the World War order by the Allied Powers. The Hiroshima Atomic Bomb of August 6, 1945 was posted on the top news on August 7, 1945 on morning edition. "First Atomic Bomb dropped on Japan;  Missile is equal to 20,000 Tons of TNT; Truman  Warns  Foe of a "Rain of Ruin". President Truman, Henry S. warned Japan or enemy countries of multiple explosions of Atomic Bomb from US Army. News Papers only reports the atomic bomb as a single large, powerful bomb by intensive information control from the US military. Most other spaces of news paper reported only the victory warfare of the Pacific War.

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.

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