We calculated in advance the number of casualties from the enemy, who would be killed based on the position of the tower. We calculated that the floors that would be hit would be three or four floors. I was the most optimistic of them all. (...Inaudible...) Due to my experience in this field, I was thinking that the fire from the gas in the plane would melt the iron structure of the building and collapse the area where the plane hit and all the floors above it only. This is all that we had hoped for
Who do you think I'm quoting here? That's right, bin Laden himself. Do you think the US government predicted what he was going to do, and then decided to work with him without him knowing?

Bin Laden would either be insulted or delighted, to hear your argument. How do you reconcile his version of events with your own?
Fallacy: Shifting the burden of proof.
You claim the burden of proof lies on the side of the argument which doesn't have to dismiss the statements made by the terrorists responsible for flying planes into the buildings :laugh:
You have yet to tie the US government into your argument
anywhere, where are the leaked documents showing that they had anything to do with planting bombs?
Remember that 9/11 was the first time aeroplanes were slammed into the Twin Towers at 450mph with nearly-full fueltanks. 9/11 was not caused by an uncontrolled chip-pan fire.
Here's an example video showing just how clueless these conspiracy theorists are. This video shows firemen apparently standing in the glow created by the "2000C molten steel" :laugh: .

In this case, it sure as hell isn't molten steel, because otherwise those firemen would be writhing in agony; it's "simple physics".
Here's a link to a one-stop news source on demolitions having their say on the 9/11 collapse:

You fail to address the source of the energy required to achieve the destructive result witnessed.
Can you give me the paper in which all of this is calculated? You see - after collapse begins, the physics are the same, whether it's a controlled demolition or not. The fall doesn't have to crush stories below it, by the way, all it has to do is break the welds and joints on the beams. I suspect bad physics on your side.
You fail to address the lack of physical mechanism for mid-air pulverization of the material in the building, and the lack of a force to project heavy material laterally outward.
I've got a quote in response to this which is just perfect:
This just makes me shake my head in wonder. First, the expulsion of air from the towers would have been pretty impressive, second, air rushing in to fill the space formerly occupied by the towers would have been equally impressive. Falling debris would also have displaced a large amount of air. Together they would have created a huge amount of turbulence, just what was seen at Ground Zero.
The drywall used around the central core of the towers was an inch and a half thick.
You also accuse me of ad-hominem towards the "conspiracy-nut", or as you would have it, physicist, who I quoted agreeing with me? Great argument! :laugh:
As for "pulverized" concrete - you must respect the inverse square law again. How the hell did enough explosives go off during the collapse of the towers to "pulverize" all the concrete without us noticing? The answer is that this level of "pulverization" is what you get from a gravity-driven regular collapse of skyscrapers like the twin towers, not from a controlled demolition.
Not only that, you haven't even read my previous posts properly, and so haven't noticed my justifications for the "force to project heavy material laterally outward".
You failed to address the path of least resistence. Reciting the official story does not validate the claim.
You can't extrapolate what you see in collapses of small buildings to the twin towers. A small building might tilt intact, but it's a whole different ballgame when dealing with an enormous skyscraper. Furthermore, a general physics axiom isn't suitable for dealing with these situations. Look where you got yourself when you tried to use convection of the oceans against me in the global warming debate.
Haha, you're right. Implosion was indeed the wrong word for describing the collapse, since the buildings fell in an uncontrolled fashion, quite unlike a controlled demolition. Videos show large portions of the towers, some as high as 30-40 stories 'laying out'. This is why there was significant damage around the towers; the towers didn't telescope down.
You failed to address the violation second law of thermodyanmics.
:embar: I can't argue against the second law of thermodynamics, but you can't use it as an argument either. Application of a simple law to a complex situation is asking for trouble, but I'll ask about on some physics forums to see if there is anyone who can rip your argument apart.
The collapse of the towers wasn't a perfect vertical collapse anyway.
Fallacy: appeal to vividity.

Yes, you pointed out your own fallacy quite well.

Anyway, I'd like you to address the two points which I think are key here:
1) What about Osama bin Laden's statements on 9/11?
2) Where is the actual evidence that the US government was involved?
