How long do you think it would take to pull this off? It took several years of planning and prep work. The full sequence of events is depicted in order from the $5 to the $100, not just the $20. It took several years of preparation to rig those buildings to implode so perfectly. The planes were just used to hide the fact that it was the govt. Do you know about the third building? Not many do. It was a couple blocks away and fell in the exact some way without any plane hitting it. But it housed al the documents that were being investigated when it was found that a certain agency couldn't account for about $9 trillion! The evidence had to be destroyed.
