Yes, it's tortuous, but try to stay with me. If the plane came in from the North of the Citgo, then of course it couldn't have knocked down the light poles, so they had to be planted. But get this - the damage pattern inside the Pentagon clearly was lined up with the path that points back at the light poles, so a plane from the North of the Citgo could not have made that damage! Therefore, the most parsimonious explanation is that the jet didn't hit the Pentagon at all, therefore it must have flown over without hitting it, therefore there must have been something else that caused the big explosion. But all those witnesses thought they saw it it, so it must have been exquisitely timed so that the explosion happened at just the instant that the large airliner-sized plane pulled up and flew just over the Pentagon's wall. No one reported seeing this flyover, because the news media immediately pounced on the scene and planted false memories in the witnesses by asking "did you see the plane that hit the Pentagon?"
I'm serious, this is his explanation. Why he trusts the damage pattern inside the Pentagon that disproves a plane strike from the wrong direction, yet dismisses all the other evidence from within the Pentagon, such as identified plane parts, DNA of its passengers, and the flight data recorder, I don't think I'll ever know.
