I'm surprised that video didn't turn on a lightbulb in your head. There's a reason why I showed you that video.
Instead I'll take the time explain.
Do you know what you're doing wrong? You're comparing the twin towers to a typical demolition setup. You're acting like the twin towers imploded from the very top level of the building and went down all by it self.
Take another look at the video. Did a lightbulb go off yet? Do you finally see the huge upper tower in its sheer size crushing the weight of the heated floors? Yes, it's that upper part of the building that's crushing down the building.
In the manner of falling down, it is equivalent to a free fall BECAUSE something is pushing it down. Yes, its the behemoth top part of the undamaged building thats pancaking all of the floors beneath it. You say pancaking would ideally take 110 seconds, does that include the upper portion of the building? Are any of them the sheer size of the twin towers? (Are you forgetting how big that building is?)
Why do people keep dismissing this important part? Take away the that upper part of the building and you would have a serious case of demolition. Now put back that huge upper part of the tower and whaddya know, kinda puts everything into perspective doesn't it?
"Debris ejected" yeah, they have to go somewhere if the floors are pancaking.
"No building ever been brought down by fire" yeah, none of them were hit by a Boeing 767. This isn't your grandfather's little plane. Instead of going around in circles here, this is what I want you to do.
I've read all the websites you've already read. (really) I've watched all the videos they produced (including loose change). Why don't you give your self a chance to see the "other" side of the equation here. If anything, you'll expand your mind.
