It's shot late in the day apparently by an FBI agent getting on 395 from Columbia Pike at the ramp right before the Sheraton headed towards the Pentagon.
Watch 10 minute video here:
After he goes through the overpasses and gets to the point where a witness would have been able to see the plane and the Pentagon you can see how the trees that we have pointed out before really do block the alleged impact point rather thoroughly until you get up almost to the point where you would be directly under the plane on the official flight path.
As we have stressed in the past there is only this tiny stretch of Route 27 less than a quarter mile long where someone would be able to see the plane and the Pentagon but tress block most of the view until you get underneath the overpass sign.
But at that point it would be approaching from behind you so you wouldn't have a view of it approaching at all unless you were looking backwards for whatever reason.
Here are screen shots I took from the video:
Frankly there isn't really anything else of much interest in the video to me other than the strange roof fires.
