The Buzz site seems to have picked references very selectively to stoke up a case for a conspiracy. I followed the news on this very closely at the time. Just after the hijacking there were several documented accounts of passengers who said they were going to try to overpower the hijackers. It was also reported that shortly before the crash a voice speaking accented English was heard saying in the cockpit 'What are you doing here? Get out!' It was also widely reported that in several cell phone conversations the hijackers said they had a bomb. Don't also forget that by then the WTC planes had already crashed and the passengers were aware of this so the element of surprise was gone - they knew what was in store. None of this was mentioned, as I could see in the above site links. Ok you can say that was all disinformation but then how far do you go in a hall of mirrors?
