Thank you. End of Story.

That picture is not conclusion that flight 93 wasn't shot down.The article quotes a man working a half mile away from the impact as saying "there was a 10 mph breeze blowing".
Any wisp of white smoke or fuel vapor trailing the disabled craft would surely have been dissipated by a breeze that strong 30 seconds after impact.

If that pic is legit, there was no missile or anything involved.

The islamic guys simply drove the plane into the ground instead of giving up.
