Just watched it now. No one will be surprised that it contains one major inconsistency just within the video.
In the later part of the video, he says that the security cam footage of the Pentagon plane actually shows a "dust trail" following the missile. However, in his "aerial shot" of the missile, no such dust trail can be seen.
And while we're at it, doesn't the existence of an aerial shot of the Pentagon disprove the Truthers' assertions that any plane that flies close to the Pentagon is shot down by some automated AA system?
