I don't understand all the "hoo-ha" with the helicopters, but the pyrosomething flow seemed pretty credible. Also... didn't the wind sound like "explosions"? I haven't watched, and compared the "explosions" to the "wind noise", but it just sounded similar to me... there's no doubt though that WTC7 was controlled demolition. No doubt in my mind. The penthouse crumbled in on itself... from fires all the way down below... and then it just turned to dust. I like the radio broadcasts he played with the movie... I thought they were interesting. I thought the way he explained himself was good. If I was smart, I might understand what the hell he was talking about, but it was good. There were so many helicopters that day. From the police, the port authority, the news stations, etc... why that guy asked for him to turn off his camera, I don't know, but the whole helicopter thing is "wierd" to me. They mentioned the helicopter that was seen over the Pentagon as well... how hard would it be to see if there were any arrivals on that morning, etc... aren't there logs for that kind of thing? I'm going to have to get Rick here to talk about this movie...
