This isn't final yet, but it does have both picture and written explanations:

I looked at that NIST report and it's really hard to determine if they could possibly be intentionally misleading U.S. for some reason. And it's still kinda' hard for me to believe that tower 7 fell in 8.2 seconds because columns 79,80 & 81 failed to support their load from top to bottom of the structure. Especially when you consider the extremely small amount of fire that exist in the building prior to it's collapse.
After going over everything they have to offer two or three times I scrolled back to the top and looked at the image the background and the full name of the NIST, and something caught my eye.
NIST is a division of the U.S. Dept of Commerce, and my old coon-ass next door neighbor Billy Tauzin was the chairman for the DOC right up until
"January 3, 2005, the same day he left Congress, Tauzin began work as the head of the Pharmaceutical Research and Manufacturers of America, or PhRMA, a powerful trade group for pharmaceutical companies. It was reported that they had offered more than a million dollars per year for his services, outbidding the MPAA (L.A. Times, February 9, 2004). Two months earlier, Tauzin had played a key role in shepherding the Medicare Prescription
Drug Bill through Congress, which had been criticized by opponents for being too generous to the pharmaceutical industry."
I copy/pasted that last part straight out of the dictionary.
Let me tell you something, that man and this government is as crooked as a snake selling kisses, but for some reason I just keep making more enemies for explaining such an obvious source of poisoning.
One day he calls the shots for the dept of commerce, next day he's the ceo of PHARMA.

And now he calls the shots for all of these companies:

And these RESEARCH companies:

this could all mean nothing.
