The trial of Zacarias Moussaoui, the mentally retarded fall guy who is admittedly stunned and brainwashed into playing the part of a Punch and Judy puppet, is acting as a form of operant conditioning, negatively reinforcing the official version of 9/11 by re-running the horror of that day.

I don't think it is a coincidence that the debunking campaign against Charlie Sheen's public stance on 9/11 has been dovetailed by an increase in focus on the Moussaoui trial.

Former Mayor Giuliani went into much depth about the screams of the dying victims yet curiously avoided the fact that he told Peter Jennings he had got a warning that the trade towers were going to collapse before vacating the area. How Giuliani knew that for the first time in history steel buildings would collapse from fire damage is intriguing. Why he didn't pass on that warning to the firefighters and initially oversaw the order for the buildings not to be evacuated is damning.

Something else that (pardon the pun) flew under the radar in comparison to the Flight 93 tape was photographic and video evidence of what hit the Pentagon which was aired at the trial.

"Another photo displayed to the jury in Alexandria, Virginia, taken by a parking-lot camera showed the explosion of the jetliner striking the Pentagon building. Sixty-four people on the plane and 125 military personnel and civilians in the Pentagon were killed. FBI Special Agent Jacqueline Maguire, who investigated the crash of American Airlines flight 77, described the photos for the jury," reported Bloomberg.

"While the material was supposedly toned down in response to defense lawyers' complaints, it included videos of American Airlines Flight 77 hitting the building at 530 miles per hour and photos of charred bodies of some of the 64 airline passengers and crew and 125 Pentagon workers who died that day," reported the Arizona Daily Star.

Why Americans have had to endure endless replays of Flight 175 hitting the south tower yet not one has seen Flight 77 hitting the Pentagon (bar a few grainy frames) remains to be seen.

Many fear the government intentionally set up 9/11 skeptics to erect a straw man case which they could later demolish by publicly presenting the video. That could happen within days if family members don't object but three currently do.

Of course, hardened truth seekers will remind us that we saw Forrest Gump shake hands with JFK over ten years ago and that simulating such a visual is not beyond the realm of plausibility.

But to distance ourselves from allegations that whatever evidence the government produced we wouldn't believe them, the fact remains that alleged voice tapes from Flight 93 do not explain how an aircraft that supposedly nose dived into a Pennsylvania field fully intact before it hit the ground created a debris field 8 miles wide.

The government is certainly not reluctant to release tapes that contain voices of Arabs shouting Allah Akbar but seems to go shy when the tapes contain conversations between air traffic controllers, as the New York Times reported

"At least six air traffic controllers who dealt with two of the hijacked airliners on Sept. 11, 2001, made a tape recording that day describing the events, but the tape was destroyed by a supervisor without anyone making a transcript or even listening to it."

Officials destroyed the tapes despite FAA orders to retain all evidence relating to the events of that day. So keen were 'quality assurance managers' to get rid of the tapes that one, "crushed the cassette in his hand, cut the tape into little pieces and dropped them in different trash cans around the building."

The tapes included conversations between the air traffic controllers and people on the hijacked planes. No doubt that the tapes included conversations about the wargames that the real attacks were piggy-backed onto and also tidbits of information from the helpless passengers that would completely reverse the accepted orthodoxy of Arabs with boxcutters.
