I think you need to ask yourself why you are prepared to believe one report over another. I think this says more about your prior disposition to one version vs. another. I think you should watch another documentary called Fahren
hype 9/11 which shows just how badly Moore twisted the story to achieve his own ends including taking Bush out of context to make him look bad but when you see the entire context it looks fine. Truly a excellent example of media manipulation.
When you pose questions about how planes could bring down a building you present them from a point of view of knowledge about how buildings collapse, how planes explode, and the physics involved in how those events work. But do you know this? And do you have access to the true facts of those events? I think none of us do and so anything we believe we believe without actually knowing the truth. Hence we believe what we want to believe or are at the very least already pre-disposed to believe. Think about this.
Personally I think you should re-consider the source of these conspiracy theories and whether and why they should carry more authority and weight than the version of the stories made by thousands of experts from many countries. Personally I stand with the US on this and the USG version of events. I think we all should.
