Destroying a Superbolide

Science-fiction work "Destroying a superbolide" deals with the meteorite, which fell on Chelyabinsk in 2013. The celestial body was going to cause major disaster in one of the megalopolises of China. It was reported to the astronomer of Kitt Peak National Observatory, Michael Pershing by the aliens, who arrived in Arizona. The American scientist begun to cooperate with the aliens in order to prevent disaster. This wasn't easy, as FBI chased the aliens. Despite this, Michael and aliens left the United States and went to the territory of Russia by UFO and changed the trajectory of the meteorite by hitting it in the sky with a special weapon. Experts in the US, Russia and China understood that the meteorite was shot down by aliens. The celestial body entering the atmosphere had to be exploded once, but it was determined that it was exploded four times. Though millions of people survived the real disaster, UFO was attacked in Russia and China. UFO was destroyed in China. Michael and aliens were chased in Nepal and India. UFO came to their rescue after several difficult passages and took them to the secret base in Niah National Park in Malaysia. Michael begun longterm experiments there as a scientist to be helpful to people after returning to the civilized society. Meteorite entered the atmosphere at an altitude of 92 km with a speed of 9.5 miles per second. Ra could determine its coordinates with a special device - 540 30/ 29// east latitude and 640 15/ 58// north longitude. Each second was essential, as the speed was very high. Strangely, though Fairbanks infrasound station in Alaska was located 6460 km away from Chelyabinsk, meteorite was first recorded there. Infrared waves rotated around the Earth several times. The head of the Canadian researchers, Peter Brown, said that the smoke was 5 km in diameter and 7 km in height two minutes after the explosion. It's dust had been taken to Europe by the wind a week later. Information about the fall of meteorites on several places in Chelyabinsk region was spread. Agile groups were organized and sent to the place of insident by the order of the colonel general Nikolai Bogdanov, the commander of the troops of the Central Military Circle. Fragments of the celestial body were found in three parts of Chelyabinsk region - two in the Lake Chebarkol, one in the Zlatoust district. The fishermen in the Lake Chebarkol witnessed the fall of the meteorite fragments around. They saw 7 fragments flying over their heads and the water rose to the height of 3-4 meters when one of them fell into the lake. The thickness of the ice in the lake was about 30 sm at that time. Everything happened as the aliens wanted. The meteorite turned into a superbolide when it exploded in the sky and 90 percent of it's main weight burned and evaporated in the sky as it fell down. Only 10 percent of the meteorite, which was broken down into small particles, fell in the Earth and it's fragments were thrown in the area of 20 km in width and 100-150 km in length.
