Ahh...I see.
So you just began posting to get a better understanding on the subject. Well, read the 9/11 Commission Report and it explains everything about the day in a pretty interesting manner.
In fact, nobody can point to one inaccuracy in the report try as they may. Not one inaccuracy. Not one person can point to anything in the report that doesn't make sense.
So read the report and you'll get your "better understanding on the subject".
Why are there some members on the 9/11 Commission publicly saying a lot of information was stonewalled and blocked from being investigated by the Whitehouse and other top officials in different branches?
Could this information they wanted to investigate but were blocked from doing so bring more to what went on with 9/11 and paint a different picture behind it?
It was because the government fucked up and is trying to hide its failures.
