Either way, I know the pentagon is built to with stand attacks. And I don't believe there was any foul play involved. Like a missile or any kooky stuff like that. As far as WTC 7 is concerned I agree with moon. It doesn't make any sense why someone would believe that. But like I said in my post I am more then open to evidence that showcase what really happened. I haven't invested much time into looking at the attacks. But just doing a quick search I have already found a lengthy analysis of the pentagon attack. Link. When I compare it to the videos that I have seen, that propose a plane didn't hit the building, they are not showing a lot of the same information. Not really a surprise as I stated before "I am sure some of these videos on the internet that talk about 9/11 leave information out to make their theory work." It's hard to take the other theories seriously when they are not showing all the information. |
Trust me, I do appreciate how strong buildings like this are:
I am an enginner (not civil, but I'd say I'm more informed than your average person) and my grandfather had a relatively large demolition company that did imposions (not to this scale obviously, but the company did bid on the general hospital back in the day ) so I've picked a few things from that too.
Anyway, what goes into a building to keep it from falling over in the wind, and to keep the windows in their sills is completely different than what would be required to keep it from being penetrated by an airplane.
Keep in mind that the WTC was basically trusses surrounding a concrete core. Most of the building is open space, so if you run into it with a plane in the right spot, you could damn near fly right through it (exagerating of course).
The pentagon on the other hand is a short solid concrete structure, which is presumably going to be a lot more rigid than a glass and steel building made primairly from trusses.
