This is sad, but the simulation technology to better understand what happened is cool:

That is crazy. Of course did anyone read the remarks. Some spammers on here with their conspiracy theories.

 

You said it. The thing some people need to understand though is there are things that cannot be comprehended. There are exceptions to the rule. I have trouble believing there was that little damage done to the buildings, look what it did to the Pentagon. It destroyed most of the supporting beams. They also fail to understand the impact of momentum. Once it starts to fail with all of that massive weight and speed. The areas that were not directly impacted could not hope to stop the towers from falling. Some people have too much time on their hands and too many instructors brain washing them.

 

I saw this on the news. Purdue University recreated this. They claim the insulation was stripped away causing the massive heat build up.

Too many people listen to the far left. If people believe the Sean Penns, and Rosie Donnell's of this country who are spewing contempt and animosity towards our country they are headed down the wrong path.
