i also tend to think this is the case. it just makes sense from the perspective of the conspirators: make it a normal demolition (well, use nanothermite on the beams, but still) and just use the media with crisis actors to propagate the planes with evil terrorists narrative. they followed the keep it simple stupid principle - the less things to go wrong, the better. and this is why no fighter interceptors were scrambled, because the pilots would see the truth; that there are no planes.

when there were no planes in shanksville and at the pentagon, why would there be any at the wtc?
