It went down after the WTC towers got hit. IT is messed up to watch, it just fell down on its own.
NOthing around it. kinda wierd if you ask me.
Not really weird at all. You have to understand a bit about engineering (mostly structural tolerances) coupled with force (mass and energy). Remember, the WTC towers were huge buildings, a few hundred thousand tons each with load. I've seen estimates as high as 500,000 tons each but let's safely say 300,000 tons each, so 600,000 tons of mass. That kind of mass creates an amazing amount of kinetic energy when in motion. All of that mass was converted into energy when the towers fell, and the energy created when all of that mass collapsed into the substructure of the Manhattan island was extremely destructive. I had the privilege to listen to a young lady who worked in the J.P. Morgan trading house which is within a block of the WTC area, and she was present when the towers came down. Her tearful description of that day I will never forget, and her description of the literal earthquake that occurred when the WTC's collapsed was no less amazing.
Many of the other WTC buildings, including WTC7, sustained structural damage as a result of the WTC towers falling. Specifically in WTC7's case, the amount of damage was so severe that the building simply collapsed after the WTC's did.
