I've been watching those demolition shows on the Discovery Channel for years. It?s interesting to see all the effort put into making buildings fall correctly insuring there is no damage to neighboring buildings. It just raises an eyebrow to how the 5th and 6th tallest buildings in the world fell right on top of each other from being struck by airplanes. Surely the damage created by the planes would create some sort of weakness on one side of the other, yet they fell perfectly. I know I'm no demolition expert, but it sure looks like one was behind it.
