The weather in Nagasaki 15 days.

At that time, the atomic bomb was transported by plane, and the pilot aimed at the target with the naked eye for bombing. At that time, the weather in the warehouse was very bad and dark clouds were gathering, which blocked the pilot's sight, so the target was Nagasaki Island, Japan.

Due to the technical limitations at that time, if missiles were to be dropped at that time, it was necessary to rely on the pilot to judge the target and then carry out the bombing mission. Previous missiles could not locate the target accurately. Bombers usually fly at low altitude, and the location and time of throwing are judged by the naked eye and technology of the pilot. But the atomic bomb is so powerful that if it is thrown at low altitude, the plane may not escape. Therefore, throwing an atomic bomb must be at an altitude of about 10,000 meters, so that the distance between the explosion point of the atomic bomb and the plane must be more than 10,000 meters to fly safely. The disadvantage of high landing point is that it is difficult for pilots to locate accurately with the naked eye.

During World War II, the United States sent two missile bombers and two old-fashioned reconnaissance planes with atomic bomb warheads to take off from the US Air Force Base and fly to the bombing site. When the plane arrived over the small warehouse, dark clouds rolled in the sky and the target was invisible to the naked eye. As a result, the plane flew back and forth three times over the small warehouse in 45 minutes, and finally decided to give up bombing the small warehouse and fly to Nagasaki, the second target. The pilot then turned to Nagasaki, where the weather was fine. The American B-29 bomber dropped the atomic bomb at a height of 9000 meters. After 60 seconds, the atomic bomb exploded at an altitude of 503 meters above the ground.

Therefore, it is not the United States that wants to drop an atomic bomb in Nagasaki, but God's will. At that time, because the pilot judged that the initial target warehouse was not suitable for throwing atomic bombs, the pilot dropped the atomic bombs on Nagasaki Island. This is also a historical necessity and cannot be changed. Let's just pray that there will be no war in the future.
