Ok, folks, this has descended into minute nitpickery over irrelevancies and done nothing more than enabled an attention seeking stunt. I think we all need to remember what Ryan Mackey laid out in this post:

This part specifically applies:
Factual error: The towers were turned to dust.
Arguments employed to support this error: Ambiguous allegations about the characteristics of this supposed "dust", none of which get tied into the collapse mechanism or demonstrate what's supposedly wrong with the currently established narrative. Also: Random recitations of standard trutherisms.
Further factual errors: Multiple and myriad ones; there are allegations to energy weaponry and fake planes, for example. No support is given for either.
This is nothing more than a display of a strong irreducible delusion. No discussion regarding the dust or any other point is productive. The convergence of multiple lines of evidence already establishes what happened. Nothing posted by the OP even indicates a problem with that, let alone establishes a logical, reasonable alternative. This thread has been done for some time now, and all we're doing is kicking around a corpse of a discussion.
The root mistake is identified above. Letting it go now. This thread and poster goes on ignore from here on out.
