With Sept 11 coming up...

I haven't seen the evidence on that either way, I admit ... but in a common sensical, on-its-face way ... I am cynical about those buildings simply collapsing because of the collision damage, heat and fire.


I witnessed the Towers being built on a weekly basis. I've seen their skeletons and such, and I just don't see how damage at the tops could bring the Towers down.

The explanation (as seen on scientific shows) is actually quite simple.

First, the planes hit closer to the middle than to the top (CORRECTION: ONE of the planes hit closer to the middle, the other was closer to the top). Plane crashes into building with full loads of fuel. Plane and building start burning. Burning jet fuel starts flowing down building on the inside, burning at MUCH higher temperatures than the building was designed to handle, weakening the steel and causing those levels to collapse. Force of impact of the top half of the building into the bottom half was too much for bottom half and it collapsed.

If you prefer a more detailed explanation, I found this, this, and this (as well as a ton of others if you search Google).

The changes in how the weight is distributed would have enough sheer force to easily implode a steel frame building regardless of size. The shaping charges in building demolition alone would do little damage even if put all together and exploded in the middle of one floor but remove enough structural integrity by cutting key supports brings a cascading amount of eponental pressure to bear.

And putting heat and fire as equals is incorrect
the fire triangle is: heat fuel and oxygen this creates
fire.

The jetfuel and office enterior (Fuel), impact (Heat) and gaping hole produced by the collision damage provided enough (oxygen) to make a largescale blast furnace wich could indeed melt steel supports which BTW only need to be weakened not cut in-order to cause an implosion.

I thought you guys believed in science. If benifit of the doubt is too much to wrap your bean around try out try Occam's Razor
