I think its worth checking out. Ive watched quite a few building demolition videos and building 7 falling looks exactly like a controlled demolition job and there were MANY reports of explosions before it fell... Makes you wonder.Experts are a dime a dozen around here. I haven't watched the video but may do so but honestly don't put much stock in the conspiracy. There were way too many people in those buildings on a daily basis and most likely most hours of the night as well,for someone not to have seen something. The odds of being able to pull something like this off undetected and keeping it a secret are astronomical in my book. Now if you asked me if I think the Saudi's were involved, that would be a different answer.
