I would happily defer to Huntsman as I'm not a demolitions expert. But I do have experience in engineering failure analysis and can make a couple of categorical statements on that aspect. A controlled demolition would leave an unmistakeable signature on the steel.
You mean like this?
Note the smoking beams in the lower left. Must be kerosene.
Explosives, and it would have to have been tons, would leave residue all over the debris. And if they used shaped-charge column cutters on the steel columns, which I think is the most likely method if I bought into this part of the CT, the debris and especially the steel would have no end of copper residue on it since the cutters work by using a jet of hypersonic copper to cut the steel. I'm no structural engineer either but demolition would result in steel that exhibited cut ends; many, many cut ends from all the demolition charges. As opposed to lots of bent, torn or stretch-like-taffy-till-it-broke ends.
I agree, except that if we are to assume that resourceful people were responsible for this demolition, and I think that's a reasonable assumption to make, they would only use just enough explosives to allow gravity to take over and do the work:
“If I were to bring the towers down, I would put explosives in the basement to get the weight of the building to help collapse the structure.”

Of course, that doesn't explain the massive pyroclastic-like dust clouds and the horizontal ejection of debris near the
top of the towers as they collapsed. But then again, neither does the official conspiracy theory.
And I suppose this is the point where our CT brethren gently point out to me that I'm forgetting about the army of Illuminati-bred hamsters that, wearing these really, really, really cute camo Nomex firesuits, fanned out into the still-smoldering debris and used these really, really, really tiny little wire brushes to scrape away all trace of HE and copper before the forensics lads showed up. And oh yeah, gnawed with their titanium tooth implants on the cut ends of the steel until it didn't look cut.
What forensic investigation? Controlled Demolition was the only entity allowed on the scene following the disaster, and the evidence was shipped off to China for recycling. After all, we didn't really need an investigation. Terrorists led by Osama Bin Laden did it! I know this because he admitted it on tape. Lets Roll!
Interesting how Controlled Demolition was the same company that cleaned up the Alfred P. Murrah building -
under armed guard - in the government sponsored Oklahoma City bombing.
You don't have to commit the perfect crime. You just have to control the investigation that follows.
