The ultimate question of which no one can answer is that if this was an inside job, why use airplanes in the first place, why not just use a couple of truck bombs?
They like to say it was a "controlled demolition".
It's amazing that the explosives were exactly in the exact area where the planes hit. Or, maybe the planes didn't actually hit the towers. It was all done with mirrors and the passengers on the planes were in on the conspiracy...all given a million dollars and a one-way ticket to Bora Bora. Yeah, that's it.
