Conspiracies and Conspiracy Conspiracies

So, I watched this video last night. And it attempted to answer two of the questions that I've always had about 9/11.
#1. How could the people on flight 93 make cell phone calls to the ground?
#2. How come the passengers of flight 93 weren't able to take back the cabin and take control of the aircraft?

Unfortunately. It's explanation is that the US government was organizing the Attack to create an excuse for the subsequent forays into the middle east. Now, I'm not saying that this is impossible. However, it strikes me that it's highly improbable. It would take thousands, if not tens of thousands of people to organise something of this magnitude. That is far too many people to watch to prevent the one guy with a guilty concience from giving evidence to the media. I mean, since most far leftists love criticizing the Government for it's lack of competence in most things. They're giving them a ton of credit for being able to pull off a plan of this magnitude and complexity.
Also, most of the "research" in this film is easily explained away, and in some cases the sources that they cite are furious for having their comments taken out of context, or being edited in a way to spread misinformation.
So, my personal conclusion is that the US government did not conduct the attacks. But, that doesn't mean they did all they could to prevent the attacks either. I suggest watching the documentary above to familiarize yourself with the conspiracy theories, and then reading the article below to debunk them. Then do some research on your own to make a better decision.
