Look Carol, if you don't even know how the damn thing was built - even in spite of watching it go up and having access to all the explanations. Even if in spite of that, you still believe that it was built from mashed potato and butterfly wings, what point is there in discussing it with you.

It wasn't built as you say it was. You are just plain wrong. You are watching videos about a process you don't understand and you are living in total fundamental error as a result.

Even if the core of the building was made from jam, snowflakes and prayers, it doesn't change the process of the collapse. Damn, it happened three times - 2 x WTC towers, 1 x WTC 7. Steel frame buildings involved in raging, uncontrolled fires exacerbated by structural impact damage.

That is the way all tall buildings will fail in the same circumstances.
