Gumby is right about that meteor that hit in Siberia. There is a book about it titled "The Fire Came By," which is what one of the local natives said about the night in question. Remember, this was in about 1910 so it took quite a while for news to get out about it, and even longer for scientists to arrive at the scene. What they saw was latter compared to the devastation at Hiroshima and Nagasaki in that directly under the blast, everything that was still standing was standing straight up. That which was off to the side was lying in a position directly away from the direct blast site.
This is a fascinating book. I read it back in about 1974. The book is out of print now, but it can be found in libraries, of course and in some rare and hard to find book stores. It's a good read if you're scientifically oriented at all.
