9/11 Building 7

I had no idea until today that 3 buildings, not just the two trade towers "pancaked" into nothing on September 11, 2001. The third building, building #7 stood until 5:00 PM that day, then pancaked into nothingness. It was not hit by an airplane or debris and was not heavily damaged. Look at the videos of the collapse. If you are like me, it will give you chills and remind you of the many planned demoltions you have seen in Las Vegas and other cities.
