I was wrong in using "foil hat" crowd as I believe you should always question information being fed to you and never rule out all possibilities.
That being said, no I'm not 100% 9/11 wasn't an inside job, but I am 99.99999999999% sure it wasn't.
I haven't done very much research on the subject but I'll try anyway to show why I believe this.
#1. Logistics. Sorry, but I just don't buy that the government could even be capable of such an operation. The amount of inside people required to pull off such a job would be staggering and leave too much risk that one might defect or reveal the truth. It just doesn't make sense from a "top secret" standpoint.
#2 Risk. To pull off an attack on US by the government on such a massive public scale would be insane. Think about what would happen if the public found this out?? It would be instant anarchy. No way would anyone with any amount of intelligence with an agenda decide that this would be the best way go about their diabolical plan.
#1 & #2 I believe prove to me that this wasn't an "inside job". It would be stupid and risky. That's really all you need to know to disprove all the conspiracy theorists.
Now I will say, there are some interesting things that happened that leave me to think "hmmm.. why did that happen?" But i'm looking for a scientific answer, not a foil hat answer.
For example. The architects said that the tower was built to withstand multiple aircraft hits. But that's all theory as Will said. Did they also figure the chimney effect of thousands of gallons of burning jet fuel inside?
Witnesses claim the airliner had no windows, was painted grey, and some camera's caught a strange attachment to the bottom of the plane. OK, interesting, but again, in this day of camera technology, would something so obvious as not painting the jet to look like an airliner really happen??? Does anyone really believe that this so called massive inside job would happen and someone forgot to paint the plane like an AA jet?
Of course not. Which to me, discredits all the fringe eyewitness accounts from this to hearing explosions to not seeing any bodies etc.
I could go on, maybe later.
