What is the detailed story of the Nagasaki atomic bomb incident?

On August 9th, 1945, the second airdrop mission fell on the sweeney crew of the 509 mixed brigade. Sweeney once led his crew to fly an "art master" observation plane to observe the bombing effect in the Hiroshima bombing.

As the "Master of Art" still retains scientific instruments, it will be used as an observation machine again. Sweeney had to use another 1 B-29 bomber-"Bok's Car" as the carrier of the atomic bomb.

At 3: 39 in the morning of August 9, the "Bok Car" carrying "Fat Man" took off from Tianning Airport and flew to Japan. Sweeney prayed again and again, hoping to be as lucky as paul tibbets.

However, things are not going well. Shortly after the plane took off, it was found that one of the fuel tanks was out of order, and 600 gallons of fuel might be unusable. Sweeney roughly estimated the voyage, thought that the fuel was basically enough, and decided to continue flying.

When "Bok's car" flew to the air assembly point in Iwo Jima, two other observation and camera planes that took off early should have been waiting to meet him there, but he only met 1 of them. Sweeney waited there for 30 minutes, but there was still no sign of other 1, so he resolutely flew to Kokura.

At 9: 05, Bok's car flew over the small warehouse. On this day, the meteorological conditions over the warehouse were very poor, the air was covered with thick clouds, and the ground was also filled with smoke, with extremely low visibility.

"Bok's car" circled over the small warehouse for three weeks, but never found the aiming point-Arsenal 5. At this time, Kokura's ground air defense forces fired intensive anti-aircraft guns, and sweeney had to raise the flying altitude.

When sweeney decided to search for the target again over Kokura, he received a report from the radio operator: judging from the interception frequency used by Japanese interception aviation, there might be a fighter plane taking off to intercept. There was panic on the plane. Sweeney didn't have time to contact the base, so he turned around and flew to the southwest.

He decided to bomb Nagasaki. After leaving the warehouse, he ordered to send a message to the base: instead of dropping bombs on the warehouse, he bombed Nagasaki. 10: 28, the plane arrived over Nagasaki. It happened that Nagasaki was cloudy that day, and the 1 flight failed to find the target when it entered Nagasaki.

The pointer of the fuel gauge is dropping sharply, and sweeney is extremely nervous. He decided to throw the "fat man" out anyway when he entered the second time, so he announced to the crew on board: "aim with radar, prepare for bombing, and return."

Bomber Cmit Bihan is as old as Fiabi. When he was ready to aim with radar equipment, he suddenly found a big gap between the two clouds below him. Through the gap, he can clearly see the aiming point-Mitsubishi Heavy Industries Nagasaki Shipyard. He immediately informed sweeney that he could carry out visual bombing.

10: 58, "Fat Man" left "Bok Car" and flew to Nagasaki. After the bombing, Bok was seriously short of oil and had to land in Okinawa to refuel on the way back.

After a 20-hour flight, Bok's car returned to Tianning Island very late. The explosion equivalent of "Fat Man" is larger than that of "Little Boy", but Nagasaki is surrounded by mountains on three sides, and the loss is smaller than that of Hiroshima.

165438+ at 0: 02 a.m., after the attack on Hiroshima, the US military conducted the second atomic bomb attack on Japan. A commando team consisting of five B-29 bombers dropped the atomic bomb "Fat Man" on the center of Nagasaki.

"Fatty" is a plutonium bomb, about 3.6 meters long, with a diameter of 1.5 meters and a weight of about 4.9 tons. TNT equivalent is 22,000 tons, and the explosion height is 503 meters. The bombing caused more than 654.38+10,000 people of Nagasaki's population of 230,000 to be killed or missing that day, and 60% of the buildings in the city were destroyed.

The injuries caused by the atomic bombings in Hiroshima and Nagasaki have been left to this day, and survivors have suffered from radiation sequelae such as cancer, leukemia and skin burns. According to the statistics of relevant Japanese departments, so far, the number of people who died in Hiroshima and Nagasaki due to atomic bombings has exceeded 250,000 and 6.5438+0.4 million respectively.
