At Least One of These Videos Must Be Fake

This one or this one.

Here is my analysis showing that there is a major discrepency in the flight paths between these videos of the second hit. Thus, at least one of the videos is wrong, if not both. And if ONE video was faked, why was it done and what does it say about other second hit videos?

The grey squares represent the south tower of the WTC. The dotted line represents where the plane went behind the building and is a surmised path.




Note-- even if you don't believe the differences in angle to the WTC, there is absolutely no denying that one video shows the plane coming in flat ("Big Fake") while the other shows the plane descending considerably right before impact ("Blue Plane").
