Creative Speculation

Apparently you don't--and even go on to repeat what you've "learned"--and thus you go around spreading your confusion about 9/11.
This would explain your great frustration when people are not bowled over by your empty claims. You believe everything you read on the internet as long as it supports your prejudices, and you are frustrated when people who do not share your prejudices find your arguments lacking.

Who exactly measured the squibs and found that they accelerated?

Your argument about the shell of WTC7 made no sense. You claimed that the non-structural curtain wall that hung from the perimeter framing stood even when that framing distorted and fell down. That's like claiming that a wall can fall down and the curtain that's hanging from it will hide the fact that it fell down.

Life is too short to address the bogus arguments of bullshitters whose preference for bullying over persuasion trashed their credibility.

Most (and probably all) of the WTC towers' core columns were accessible at some point from the elevator shafts. Only by restricting the universe of columns to those accessible at the floor where you believe the collapses began can you give the illusion of having an argument.

I can comprehend the concrete pulverization just fine. I want NIST to explain it to me. I don't want to hear it from obsessive and anonymous propagandists.
