re: Anybody ever see 911:In Plane Site?

I am always interested in the Why...I have never heard a compelling argument as to why a missile was fired into the pentagon or why the government needed to conspire to kill three thousand citizens and destroy several buildings in our largest city.
What was the end game? Even if I could believe any of these inconsistencies, the why this was necessary is so weak as to be laughable...

Now, do I believe it's possible the plane in Penn was shot down by our military? Yes, there was a compelling reason to do that to possibly save lives. I am also ok with the government lying about this because that was a decision that needed to be made but virtually impossible to completely defend.
