I watched the video twice yesterday.  I still don't know what to think.  I don't see the missile thing in the way that is described early in the video ... the pictures aren't nearly clear enough for me to give it creedence, but that's just opinion.

I live in Arlington, and know of two  people who were in the Pentagon at the time of the incident.  Each swears it was as we've been told ... it was a large passenger plane.  Whether or not they can be believed, I can't say.  If there was some sort of cover-up, I'm the last person they'd be breaking their silence to. 

One thing that did strike me right away was the issue of the light poles.  If the jet thrust was capable of blowing a car off the runway as easily as that video demonstrated, it's quite possible that those poles were knocked over in the opposite direction by the plane passing immediately overhead. 

Still, all in all it provoked some thought.
