Why didn't NORAD respond? Supposedly, they just so happened to be doing a simulation involving hijacked planes on 9/11, so they mistook the actual event for their simulation.

What about "lucky" Larry Silverstein, who took out an insurance policy on the twin towers just before they were demolished. Lucky Larry did not go to work on 9/11 because he was supposed to have a doctor's appointment. Later, it was found that his appointment was canceled and he just decided to walk around the city rather than go to work. His family was also absent from the towers for various reasons.

"Luckily" for Larry, he and his family were out of harms way and profited billions from the fall of the towers.

That level of coincidence that believers of the official story want us to accept is ridiculous.

9/11 was an obvious inside job. The people who rigged the buildings were the ones who stood to gain from a false flag war.
