can you be a little more specific or are you just dismissing everything i linked without looking into it? :P |
I did look at one of those links. The second one.
Yes, the WTC was built with 47 big solid steel columns.
Yes, it was designed to withstand aeroplanes crashing into them.
BUT, they
weren't designed to withstand big giant fucking Boeing 767s crashing into them near top speed. If you look at the videos, you can see that the planes nearly go right through the fucking towers. It's not hard to imagine that something with that much force would severely weaken the building's core.
Add to that a rather shoddy construction lacking any sufficient fire-proofing, and you've got a recipe for disaster.
You see, the WTC's floors were made of plates covered in concrete held up with truses. These truses were fireproofed insufficiently, and they were arranged in such a way that, though extremely strong, should only a bit of them fail, they'd fail completely. Add to that most of the existing fireproofing probably being blown away by a huge chunk of metal crashing into it at 800 or so kilometres per hour, and, well, you figure it out, corky.
They were strong, but they couldn't withstand a lot of punishment, and that's why the building collapsed.
