Eighty years ago today, August 6, 1945 (June 29, 1945 in the lunar calendar), the atomic bomb exploded in Hiroshima. On August 6, 1945, the US military's B29 bomber dropped the atomic bomb on Hiroshima, Japan. On August 9, it flew to Nagasaki, Japan, causing an unprecedented disaster. Mr. Gao Limin produced a slide show of the atomic bomb explosion in Hiroshima based on information on the Internet, which was transferred to it by Teacher Xu Lingyi on August 6, 2010. The fly in the ointment is that the source of the information on the Internet is unknown and difficult to quote as credible historical data. However, it is useful to understand that the United States is the only country that used the atomic bomb and Japan is the only country that suffered from the atomic bomb. Historical facts tell us that if Japan surrendered unconditionally early and early, it might have been spared the harm of the atomic bomb. The United States and Russia are by far the countries with the largest number of nuclear weapons. If the United States and Russia promise not to be the first to use nuclear weapons under any circumstances, and if all countries with nuclear weapons and nuclear strike capabilities do not be the first to use nuclear weapons under any circumstances, then our world may be much more peaceful. [The last person to cast the "little boy" died] On July 29, 2014, Theodore Van Kirk, the last living member of the task force that carried out the atomic bomb bombing of Hiroshima, Japan during World War II, died in the United States at the age of 93. Van Kirk expressed his distaste for the atomic bomb and war in interviews before his death, but insisted that the decision to drop the bomb on Japan was correct because it accelerated the surrender of Japanese militarism and "saved lives" in the long run. Van Kirk participated in nearly 60 bombing missions during his service, but a bombing mission over Hiroshima made him famous. Before and after the atomic bombs exploded in Hiroshima and Nagasaki, Japan The successful U.S. atomic bomb test overlooks Hiroshima, Japan, after the atomic bomb exploded. In late 1944, the U.S. Marines captured Saipan after a bloody battle and paid a heavy price. The full occupation of the Mariana Islands by U.S. troops is of extraordinary significance. It is more than 2,000 kilometers away from Tokyo, enabling the United States to attack Japan from its island base for the first time. There are more than 800 B-29 bombers on Tinian and Saipan. They can carry thousands of tons of bombs at a time, fly more than 2,000 kilometers, bombing Tokyo, Sasebo, Nagoya, Kobe, and Yokosuka. After dozens of rounds, 65 cities in Japan have almost no complete buildings. At the same time, a group of B-29 bomber pilots are also receiving a special training course at Mendovi Air Force Base in Utah, USA. These pilots were strictly selected from various flying units. They were not allowed to interfere with anything except that they knew that they would one day perform missions overseas. Their organization was code-named "Team 509." The B-29 bomber used by the "509 Group" has been modified, and all heavy weapons have been removed to make the aircraft faster and more flexible. Their training subjects are very monotonous: the bomb bay that can carry a 10-ton bomb can only hold one bomb at a time, but when the bomb is dropped, the bomb must fly more than 9000 meters, and the impact point must be within 300 meters of the target. April 12, 1945, White House. An artist was painting a portrait of President Roosevelt when the president suddenly fell into a coma and died that afternoon. That night, Vice President Harry Truman was sworn in as president of the United States. The ceremony lasted only one minute. On this night, the Secretary of War told the new president something he had never heard of-a few years ago, President Roosevelt accepted a suggestion from the famous physicist Albert Einstein and decided to start developing a new weapon with unprecedented power. Relevant scientists from the United States and the United States were organized to work in laboratories scattered across the country; more than 100,000 people were working under extreme tension across the country. The plan was kept absolutely secret, and all but a few people who worked on it did not know where their research would be used or what the products they produced were for. Now, this weapon that could completely turn the tide of war would be developed in the next four months, and it would be called the atomic bomb. On June 21, the U.S. Army captured Okinawa. The Americans won, but fought for 80 days and lost 48000 men. Japan dispatched 2400 "Kamikaze" suicide aircraft, sinking 26 U.S. warships and injuring 164. The severely damaged warships even included the U.S. ace aircraft carrier USS Enterprise. End of June. Tokyo. The Japanese military has formulated a policy of "decisive battle in Japan." After the battles of Saipan, Iwo Jima, and Okinawa, the Japanese warlords became more confident. They still have millions of troops in their hands and have the so-called "broken jade" determination to fight for a few years to achieve a decent ending. After the same wars of Saipan, Sulphur, and Okinawa, the U.S. military was a little scared. They won all these battles, but the price they paid was so high that they did not expect. It is difficult to say how much it will cost to attack Japan in this way. In the plan they formulated at this time, the war would be delayed and Japan's main island Honshu would not be attacked until after the spring of 1946. Of course, they believe that there is also the possibility of shortening the war. They still have one card they have not played, and this is the "509 Group." During this time, the "509 Group", like other B-29 bombers based on Tinian Island, participated in air strikes on Japanese cities. The only difference is that they still only carry one bomb at a time, and each time they drop the bomb, they are required to maintain a certain height; like previous training courses, they are required to have an accurate impact point and explode within vision. After actual combat, their technology has been greatly improved and they are familiar with flying under complex meteorological conditions. At this time, only one person in the team knew why this move was repeated. He was Colonel Tibbers, who led the team. The United States 'first combat atomic bomb was divided into four parts, transported to Tinian Island by three aircraft and a cruiser, and assembled there. It will be dropped by a B-29 bomber numbered 82. According to subsequent reports from the United States, in a short period of time before the atomic bomb was dropped, either for psychological reasons or for any other reason, the well-trained "509 Team" had accidents one after another, and four B-29 bombers were damaged or completely scrapped during take-off and landing. On August 5, Colonel Tibbers convened a meeting of all members of "Team 509", which was a disclosure meeting. He announced for the first time that the "509 Team" had been training for 10 months to drop a bomb in Japan, but it was not an ordinary bomb, but an atomic bomb equivalent to 20,000 tons of TNT energy. The 82 B.29 bomber will be piloted by Colonel Tibbers, with the original piloting Robert Lewis as co-piloting. No one on the crew understood the structure of the atomic bomb. Colonel Persens, a technical expert, was ordered to fly randomly. Once he was arrested while failing to complete the mission, Persens should immediately be loaded with the atomic bomb on aircraft No. 82. Accompanying the 82 plane were five B¡¤29 bombers, two of which were responsible for reconnaissance and three of which reported weather conditions at any time. The bombing site is then determined based on weather conditions-Hiroshima, Nagasaki or Kokura. At 2:40 a.m. on August 6,"Team 509" was preparing to take off, and aircraft No. 82 was temporarily named "Innogayi", which was the name of Tibbers's mother. The plane skidded off the runway and took off. Colonel Persons climbed into the bomb bay, unlocked the safety device of the atomic bomb, and installed the detonator. From now on, in Churchill's later words, aircraft 82 is loaded with an "angry Christ" who will be born in a few hours. At 7 o'clock, the sky was clear. At 7:30, preparations were made for dropping bombs. It is now possible to determine where the atomic bomb was dropped. Hiroshima and Nagasaki are not far apart, the former is in the west of Honshu Island, and the latter is northwest of Kyushu Island. Target: Hiroshima. At 8:35, the two "Group 509" aircraft accompanying the "Enogayi" quickly left. At 9 o'clock, the crew of the "Innogayi" put on thick sunglasses to prevent the strong light from damaging their eyes. At 0916 hours, the atomic bomb was dropped out of the bomb bay. On this day, all clocks in Hiroshima stop at 9:16. The atomic bomb exploded 600 meters above the ground. After flashes, sound waves and mushroom-like clouds of smoke, flames and smoke shrouded the city. 60,000 houses were destroyed within 14 square kilometers of Fangyuan, and nearly half of Hiroshima's 300,000 residents were killed. Truman heard the news while on the Augusta cruiser. He was very excited at the time, but he was surprised the next day and the third day. Why didn't Japan show any sign of surrender? On August 9, the "509 Group" dropped a second atomic bomb on Nagasaki City, killing more than 70,000 people. However, the war has not stopped. Victims of the Hiroshima Atomic Bomb Scars caused by atomic bomb radiation The atomic bomb mushroom cloud over Nagasaki, Japan The atomic bomb crew took a group photo before taking off The proposal to develop an atomic bomb was put forward by Einstein to the U.S. government to establish an atomic bomb testing site in New Mexico. This was one of the two atomic bombs dropped by the United States on Japan. This was one of the two atomic bombs dropped by the United States on Japan. When Truman was Vice President, he ordered an investigation into what this big house was about. After he became president, he was told that this was the first time that the world knew what an atomic bomb was. The world knew for the first time what an atomic bomb was. The world knew what an atomic bomb was. The U.S. military plane took before the bombing. The same area after the bombing.
