It's been my opinion 93 was shot down, mainly because of the reported debris field. Remember the reports of a farmer finding a cargo door in a pond? That was several miles from the impact point. I might believe paper or insulation being carried on the wind after a crash and intense fire, but not a cargo door.
There were early reports, including video, of other plane parts found nearby as well. Mysteriously all those reports, along with the people who found debris, seem to have vanished.
There was also an early report, and noted in this article as well, of a phone conversation. The operator said the caller was near the tail of the plane and he was saying a group of passengers was going to storm the cockpit. But, BEFORE or JUST AS, the attack began there was a loud sound, the caller saying something abou the plane pitching and him seeing sky. The operator heard a rushing noise and the phone went dead.
Admittedly that was an early report, and I may have some of the details a bit wrong, but that's how I remember it.

I would love to hear comments on this subject from those in the know.
