Why the hell would you need such a complicated cover story? You'd basically be putting your plan in the hands of hundreds of possible interfering civilians, and beyond that what happens if you can't fly the plane straight and you miss? What if they'd only hit one tower and not the other?
There are controlled demolitions that don't go off right. So what are the chances that people snuck in explosives, placed them correctly, kept it quiet, then took down THE TALLEST BUILDINGS IN THE WORLD on the first try without any tests?
And, finally, to what end? That's what pisses me off about like this. "We just want to point out flaws in the accepted perception." Great. That's fine. A building collapsed in a way that buildings collapse when you do it on purpose. Now please tell me why a secret cabal would want to kill thousands of citizens, trust that everyone who was in on their plan would keep quiet, trust that their plan would go off without a hitch, then hope also that they could parlay the aftermath of the fake tragedy directly to their own benefit.
And why is the music the same as that used in Patrick Swayze's self-help video from Donnie Darko?
