"My eyes tell me that in looking at the towers collapsing, the jet fuel wasn't potent enough to cause this because it was spent outside after the plane hit."

I guess each eye can view these situations differently. From the crash I saw, I can believe that the amount of fuel could have caused this because I don't think the fuel was spent outside.

"My eyes tell me that this matches every building demolition that I have seen."

My eyes see it as randowm and not controlled. The puffs appear to match what I would expect from pressure pushing downward.

Then again, it could be controlled demolition too.

Of course, none of us really know, and probably will never know for certain.   We have to keep asking but we should not be foolish enough to buy into theories that we have not fully explored and looked at the counter-evidence.

Yet, this brings hours of endless fun for posters on Mudcat.
