Look, stickyfingerz, you are, obviously, from personally meeting you, an intelligent and reasonable guy.
The initial video you showed as proof that it was a natural or spontaneous building collapse was close-up and could stand as proof of either scenario.
The post with this link
http://media.putfile.com/WTC-Collapse-Part-ONE explicitly states that the building was hit from the east side. Besides the problem that this doesn't explain why the whole core collapsed as well, it states that the whole thing influenced/heated one side over another.
Which would mean that the building, if not the other, would have tipped rather than gone down straight.
Now I would agree with you if at least one of these buildings had an assymetrical collapse. That means parts of, or the whole, building going down to one side or another... but that didn't happen, right?
But even the latest explanation video you posted states one side or another and ignores the fact that the whole building, all three of them, went down vertically. That would mean each one would have to have had exactly spread-out fuel and fires burning equally from the point of impact all the way to the bottom, which i'm sure you'll agree they didn't or couldn't have.
And the second building "collapsed" from the top down - but the fire wasn't up there, and there weren't any fires below that. How then could the building go down in an uniterally parallel way? It was too smooth, and logistically didn't make sense.
Beyond all theories, to short-circuit any conspiracy crap, I thought I'd mention that it looked like the buildings were built with the charges integrated in the structures - which would make sense in case the things could have somehting awful happen to them. Better 3000 dead than 30,000 which is what would happen if the towers toppled one way or another, which is vastly most likely in the logistical or physical sense.
Beyond all this there's nothing else that can explain ALL the cement, concrete, whatever, of the two towers, being pulverized beyond all ability to analyze and help understand the dynamics of the collapse - IF it's accidental.
Nothing explains the collapse of world trade building seven, too... and all of the official reports admit it.
I don't know what happened; when it gets political, I know even less, it's too convoluted.
All I know is that if three demolition companies try to unilaterally bring down three buildings simultaneously, they won't achieve the almost perfect results that occurred on september 11th, 2001...
All I could say is we obviously don't agree, sorta like different religious nuts who love and respect each other but not on doctrine... and leave it at that.
history will show us all hopefully.
