Back to why doesn't AE911T fund research: It's apparent that their emphasis on the period of freefall of the North Face of WTC 7 has gotten them nowhere. In the six years or so since Chandler's discovery, it has gained no traction amongst engineers, scientists, or the general public.
Perhaps this is because that once the two penthouses have fallen and the North Face begins to fall, it's obvious to everyone that the building is at least wrecked beyond repair, and placing demolition charges in the north perimeter columns is pointless, even if it were somehow brought down by deliberate destruction.
The potential benefits for AE911T to do a simulation of the fall of the North Face are obvious. Unless the putative conspiracy placed demolition charges gratuitously, for no reason other than to mess with the minds of anyone who would question the "official story", they must have had a reason. Perhaps, if demolition charges hadn't been placed, some small portion of the building might have survived. Who knows; a little research may show that SEC files on Enron were stored there, providing a motive!
So at this point, there is no reason for AE911T not to do a simulation of the collapse of the North Face, with and without demolition charges, and good reason to do so. At the very least, it'll look good on everyone's resume.
