So what happened to the 12,000 ton Chelyabinsk meteorite?
If they only recovered 5 tons of it, where did the other 11,995 tons go? Certainly it did not convert to energy (Siberia would be leveled otherwise) and not all that mass was superheated and changed phase to gas. And I am sure that most of the fragments were not found and have become part Siberia now, but if scientists only found 5 tons, I have to think that a large majority of the meteorite did not land as solid fragments.
I have to think that much of the meteorite was blown to dust by the explosion in the upper atmosphere, and has probably precipitated out worldwide by now.
