I don't know where the plane flew precisely.
I dont know the precise speed of the plane.
I dont know the precise altitude of the plane.
I dont know if it shot over the Pentagon to the north or south of the "impact".
I don't know where it was when Officer Roosevelt saw it.
It doesn't look to me like you have much to discuss regarding flight paths.
Your assertion seems to be that all the physical evidence, both inside and outside the Pentagon, was faked.
If the evidence inside was not faked, then the vector of the internal destruction gives an approximate approach heading for the aircraft. That direction is not compatible with an approach substantially further north or south of the generally-accepted flight path, because the bank angles would be much higher than were reported.
If we assume all the physical evidence was faked, North or South of the Citgo is immaterial, since the difficulty of faking it does not change regardless of the flight path.
In fact, installing even-easier-to-break-away light poles and flying the aircraft on the path most observers agreed on would seem to be a simpler solution to at least part of the problem. (The plot does not stand or fail on whether light poles fall down during the attack, so if they're hit, fine, otherwise, who cares?).
However, the fact that all the witnesses say the aircraft that they saw hit the Pentagon would seem to be pertinent.
You maintain that you find it difficult to believe that any person could witness an airliner knocking down a relatively small and inconsequential* light pole and not notice it. Yet you have no problem at all with maintaining that
every single witness was mistaken when they report that they saw a big airplane hit a big building. That seems to be a case of swallowing camels whole, but straining at gnats.
*I use inconsequential here as in: a bicycle rider is inconsequential to a person driving a car. Any bike rider can cite many cases of drivers "failing to see" clearly visible bicycle or motorcycle riders.
