a micrometeorite could cause the vapor trail and the bright flash of impact.
That was the initial opinion on this event and nothing else has disproved that theory.
Tin Hats? this would have blown right through a skull!
Here is the link to a CLEAR picture of this event

I would put in a theory of a laser coming down after seeing this photo with the much more obvious smoke stream off the right of the pole! Could be vaporized metal...or it could simply be a camera lens false image from the flash at the pole.
There HAS to be some evidence at the point of impact - someone is NOT talking.
