I think he was talking to me
JJ, I have a lot of beliefs about it, and not everyone will agree with me. That's ok.
I never thought they blew up the building, that's insane, but do believe the building engineers had an "emergency" procedure should the building be attacked again. It would be a lot better to set off a couple of explosives and bring down some floors to ensure the building collapsed on top of itself, than to have it tip over and fall on God knows how many other buildings. This wouldn't require near what a real demolition would require, and would be put in place by building engineers after the last attack on the towers. There were reports on the ground of people hearing explosions right before it collapsed. This isn't a "conspiracy theory", but good practical engineering that came in very usefull in a time of crisis. They saved lives that way, as the buildings were coming down regardless.
As for the "attack" itself, I'll not get into that on the internet.
I still to this day have never heard why building 7 collapsed. It was far enough away from the towers, and no plane hit it. I remember when it happened thinking "WTF was that about?". No-one seems to talk about it.
