The simultaneous fall of meteorites

Question arises: what state have reached the Earth these many stones, whether they were originally one mass, which is broken up into our atmosphere, or already in the Earth's atmosphere entered a whole bunch of individual stones? If the study is not noticed meteorite crust, dressing him from all sides, but rather see fresh fracture surface, or only insignificant traces of glassy shell, almost unerringly can be argued that fragmentation occurred during the fall, this is not about the meteorites, which are dressed solid black bark: already in the atmosphere, they must have existed as independent bodies. Even with strong rains most of the stone meteorites fused, in a Paris Museum of Natural Science remains 95r "whole" of meteorites. fallen in Pultusk January 30, 1868. It is incredible that such a huge number of rounded stones formed by the decomposition of a meteorite in a few seconds, held in the atmosphere, probably all of these separate bodies moving in space is a tightly knit bunch. However, there are cases when a meteorite smashed, passing through the atmosphere to escape velocity, and reached Earth in the form of rubble, covered with vitreous cortex. For example, in Kvenguka in India were found two meteorites that are separated by a distance of almost one English mile, and their fracture surface were slightly fused, but it coincided with one another, and after the fall of meteorites in Butsure in the East Indies on May 12 1861 were found at a distance of 2 miles of British three meteor fragments, put together, they are also quite match. However, these cases are among the exceptions, and meteor showers, like those listed above in any case can not be reduced to the disintegration of one common mass. To explain their need to assume the existence of a whole heap of meteorite. Doubt has been eliminated famous representative of the Athens Observatory Schmidt. He was first able to observe in a telescope the fireball of the first order. If we take into account how often such events occur, they are short-lived, and how fast flow, it becomes clear that watching them is very difficult. Meteorite, visible through the telescope Schmidt, consisted of many parts: the front moved two yarkosvetyaschihsya greenish stone, and they took the form of a huge drop, and leaves behind a long fiery red line; them rushing greenish pile of fragments of different sizes, and each of them leaving behind a red fiery trail. It was noticed that the actual size of meteorites smaller than they appear to the naked eye, this is an extremely important fact shows that the disparity between the huge size of the meteorite and a small mass of falling rocks is an optical illusion: a strong light emitted by the meteorite that increases its size. Thus, these observations clearly demonstrated that the majority of meteorites represent a heap of stones, passing the atmosphere in the same direction, only the naked eye, they seem to be a fireball, the last conjecture has long expressed Gaydshger.
