National Geographic has a fascinating simulation of why the US World Trade Center towers collapsed after the planes hit them on September 11 2001.

It's part of a program investigating "science and conspiracy".

channel.nationalgeographic.com...-Videos/07095_00

Basically, it's because the fuel in the (nearly-full) tanks caught fire, which weakened the columns, which bent slightly, which meant that the roof - and other floors- fell in.

We know that from the real-life example, of course. But it's interesting to see it demonstrated here. Not, of course, that this will satisfy the wingnuts who think it was a conspiracy. Their loss.

But sometimes this is what engineering is about: figuring out why things happen after the event. (Other videos on the National Geographic site ask whether controlled demolition could have done the same job, and whether the hijacked planes were replaced by planes carrying explosives. Enjoy.)

National geographic? Come on gimme a break, why dont you watch the BBC's Story or maybe Channel 4, eh.

My friend i wouldnt take much notice of these mainstream TV channels, honestly.

They are payed tons of money to make these Documentarys to counter the real truth thats out there. Keep your mind open.

By the way, We are not wing nuts.. We just have the capability to use the full 9% of our brain that we are privy to, unlike you guys that bairly use 0.5% of yours..

Common sense my friend, you have none.

Do you even realize the weight of 1 floor of that building? The design of the buildings were garbage, they were a new idea in architecture, they were untested by today's standards and created to provide the maximum amount of interior space by using the outer shell as the building support.

If they were destroyed by explosives people would have heard more than 1 to 3 explosions, there would have to be hundreds going off per floor. The poofs of smoke or dust were coming from the sealed environment of an office building when the pressure had no where to go, it blew out of the weakest point. You don't see that on demo buildings because the remove all the windows first.

So the outer shell of the building would and did act like a tube with each floor collapsing down on the one below it, that much weight compounded by each addition floor and the outer shell acting like a tube is what made them pancake to the ground.

Lastly, I though ChimpyGeorge Mc idiotBush was too stupid to even think clearly? If you don't blame him, whom do blame? Cheney?

1). Air Squibs popping before collapse, your government state these are caused by compressed air as the none pancake collapse, starts collapsing and pancakes before any floors have collapsed.

3). Why in any government report does it not state the explosions clearly seen exiting every face of WTC1 the North Tower, plus the two faces visible more explosions around the hat truss sections, kept this quiet didn`t they? yet another miraculous feat from the Kryptonite hating Boeing super planes.



4). Why, milliseconds after the initial explosions (make sure to note the difference in debris between the two explosions, another huge clue)........



Seen exiting South (wtf a blast heading back over 80 metres where a plane travelling around 550 mph has just been) east and north faces respectively did all hell brake loose with this?, orange flames and white smoke to red and white flames with black smoke.



Apparently not all the fuel ignited, oh no, only a 3rd or two 3rds ignited, the rest of it had to somehow spread over 110 storeys and weaken 90,000 tons of tempered steel, and reduce to dust 110 acres of concrete, how embarrassing for NIST having to tell the whole world that the explosion seen that covered over 100 metres in height and 200 metres in length (including a back blast of 80 metres????), was caused only by part of the fuel, here to scale is a cube that is exactly 36 cubed metres (even though there was only around 34 cubed metres of fuel left.



Anyone else see a few things happening here other than 34 cubic meters of jet fuel exploding?, my money is on the 100 metre high 200 metres wide explosion that followed the initial jet fuel pop.

Over at the Pentagon it took firemen a few minutes to quell the blaze, here we have some fuel that spread over 110 storeys (in both towers..wow) and set fire to none combustible office furniture (due to insurance policies regarding high rise residency, if it burns no insurance cover) so that leaves a few tons of A4, for just over an hour and weakened 90,000 tons of tempered steel, and reduced 110 acres of concrete to dust, a 3rd of the fuel done all this 12 cubic metres = two concrete lorries full, are you guys trying to take our tin foil hat status away from us here?.

EDIT: P.S.

P.S.

Forget to mention the small factor in these raging infernos the brave fireman who made it to level 78 and described in intense detail the huge hell like apparition before him `We have two isolated pockets of fire, we can knock them down with two lines`.

Fires brought the towers down you say?, what`s that?, oh sorry, NIST theorycraft stated it, after Bush science applied it

And I hope you realize that for every action there is an equal and opposite reaction, and that an object in motion will remain in motion unless acted upon by a force of resistence.
