How many modern instances have there been of fires being started by
meteorites? I'd have thought any hot debris slamming into the earth
would do so with enough force to either bury or smother the hot bits.
Surely such a firey rain would result in lost of little explosions or
craters, rather than lots of little fires?
Of course, if there was a lot of dust in the atmosphere, lightning
strikes may have been far more frequent than usual. Then again, would a
lot of dust particles in the atmosphere also encourage precipitation?
