So I was thinking about this , what velocity exactly would cause similar effects? Or is it more of a range, like 800 F @ 250 k/p/h - 550 F @ 900 k/p/h, ( Just punching in Numbers , but you get the idea).
You said it was impossible to be formed that way naturally , but could it not have been formed by slowing in the atmosphere until it formed and fell to earth? A fragment that just didn't burn up completely? Just a thought.
