Suspicious if it hadn't happened on 9/11, if no planes had impacted the buildings at 400+ mph.
But of course, you don't think planes actually hit the towers, probably....Just a guess.
Instead, you had all this dust every place. Dust appeared at ground level before either of the Twin Towers went poof.
What happened to all that drywall and such when the planes impacted? It all stayed intact, I guess, along with the SFRM, insulation etc....
You do realize the dust has been analyzed for content? It wasn't mostly iron or steel, unfortunately for your theory. What is your theory? What was the process you claim? What would you expect to find?
YOu don't really have a coherent theory, do you? But read on and find out what the dust really was......
'The USGS Study
A study by the US Geological Survey (USGS) provides some analytical detail missing from the above study. It lists the elemental composition of a number of dust samples collected from outdoor and indoor locations. 3 The following table summarizes the percentages by weight of the more abundant elements in samples for which sulfur was measured.

Gypsum, the primary constituent of most wallboard, has the formula CaSO4-2(H20), and is 18.62% sulfur and 23.38% calcium by weight. 4 Gypsum is also about 5% of portland cement, the binder used in most concrete and constituting. Since aggregate constitutes between 70% and 80% of most concrete, gypsum might account for 1% to 1.5% of the concrete in the towers'

Keep flapping around, seems like you are wont to do it. It won't change the facts. Flap all you like, squawk all you like, it won't make your fantasy come true.
