So how should they have "reacted" when hit by two 747's? What exactly would have been an acceptable collapse or implosion? Toppling over to the side? If they would have done that I'll bet people would've been talking about how poorly designed they were and conspiracy theorists would have said that someone detonated a bomb at the base to cause the topple.


767's - much smaller...Bombs were in the basements - look up Willie Rodrigez (sp?). Lots of other testimonies too but he was the maintenance guy - he knew where the fuel tanks were and where the explosions were occurring and they were on different levels - this was going on before they started coming down.

Let's see what an expert has to say about WTC design - an expert on the WTC's architecture: Frank DeMartini - died in collapse

It seems to me that they reacted perfectly to their design and that is to pancake on top of itself to minimize damage to surrounding buildings in the event of collapse. No? Does it not make sense that as the core columns succumbed to the extreme heat they would have, through connection of intermediate members, pulled the exterior steel "panels" inward thus creating an implosion effect. Then as the thousands of tons of steel, concrete, framework, office furniture, etc. came crashing down on lower floors the implosion would continue.


First of all there is no evidence that these or any other skyscraper were designed for the event of a collapse. They were built to withstand collapse, and indeed - prior to 9-11 and ever since - no steel framed skyscraper (which is what all skyscrapers are) has never before or since collapsed.

Your saying alot here and I just don't have the time to reply to it all right now but lets focus on the main thing - "extreme heat". The common argument is that you had all this fuel burning for...around 2 hrs. Examining the evidence this just isn't true. Most of that fuel was burned up in the massive fireball that followed impact. It was not a large and intense fire. The smoke is one evidence of this. Heavy smoke is evidence starving fire, not an intense one. Secondly we have radio recording of firefighters that reached the impacted floors. And we also have video and photos of victims standing in the impact hole waving for help.

This is intense heat. This building burned for 18 hours - completely.

Here it is following the fire

I apologize for the hokey nature of some of these clips - but the live footage is compelling...

Bombs in the buildings

Video is out of sync - note firemen radio transmissions.

NOVA's laughable simulation - note what is missing, and what is left standing. A Purdue production?? <img src="/forums/images/graemlins/smile.gif" alt="" />

The tremors? Have you ever heard steel snap? Have you ever heard a large steel member dropped or even just hit really hard with a large hammer? If so I bet you'd agree that there may be a small "tremor" associated with the sound, since sound waves can cause small tremors or better yet cause a small video camera to shake a little. Imagine dozens of large steel members all snapping at once while the building is collapsing. Think that might be "felt" a block or so away?


Well now you are saying steel snapped - which is not even what NIST is willing to say. The collapse hasn't happened yet so how does steel under the influence of 'extreme heat' snap exactly?

This is not snapping steel

Note in the videos above - you have no mention of fuel, no mention of fires of an intense nature but rather containable pockets of fire... we hear on the radio in the clip above a radio report from the levels where the plane hit "two isolated pockets of fire. We should be able to take it down with two lines." What is the simplest explanation? What is everybody saying? Explosions, explosive devices, dust, and things being blown apart.

I haven't seen it mentioned here but you have before mentioned the explosions heard before the collapse and I can't pass up the opportunity to throw this in as well. Just to let you know, in case you didn't, buildings have mechanical equipment all throughout that will explode when subjected to extreme heat. You know, like the heat caused by thousands of gallons of jet fuel burning. This is a pretty neat video of an electrical transformer exploding. There are also things like mechanical compressors or even fire extinguishers that can explode in extreme heat.


Again you're arguing on the premise of extreme heat - which even NIST no longer admits to. And if you listen to those testimonies in the videos above (tons more on youtube - we're just scratching the surface) - you'll notice this was going on - in the basement levels, the main lobby, and floors all the way up to the impacted floors. Even if there was, and there wasn't...intense heat, it cannot explain these explosions throughout the whole buildings.
