Agent Smith, I asked the company what different ways they could destroy a building. That's national security? Give me a break, dude. I think I'll stay here at ATS.

What most of you forget is that the steel used to create and support buildings in the U.S. must be sprayed with fire resistant chemicals before being added.
Both planes where going around 400-500 MPH.

As to the fires, the computer simulation shows sustained fires of 1000 deg C in large areas of the building, so I'm not quite sure what you're on about.
How come this miracle Thermite enables things to stay hot so long anyway? The reaction is over in seconds and if it's not possible for the metal to retain heat through fire then why is it possible for it to retain heat from a different method of heating?

Finally, the kinetic energy of the collapse itself would have been translated into a fair amount of heat, just through mechanical motion and piezokinetic breakage.

Almost any structure fire can reach temperatures in excess of 600 C.
bsbray, you are in your own little world again.

It was the top ten stories which started falling wasn't it? Which is about 10%. 20% Would be about twice that, so about 20 storeys worth ( 1 fifth of the building) - still more than enough to crush the building once it gained momentum.

Perhaps Mr Bray, you would like to now devise a system to differentiate between people wanting to deny ignorance and terrorists attempting to gather information?
As this is a big problem for all of us I'm pretty sure it will make you a rich man.
I still find it astounding why you can't see a demolition company would be cautious about witholding information from someone ringing up out of the blue asking strange question like 'how many different ways can you destroy up a building' - without actually having one to demolish.
The only thing that even vaguely implies thermite was used would be the alleged pools of molten steel which are not confirmed and some have debunked.

Personally I can see the fires that were burning under the rubble reaching and sustaining high temperatures for a good length of time.
They came to ground zero to make a connection, Native American to Native American. They came bearing the scars of another terrorist attack, the Oklahoma City bombing, to seek out those whose tribe had helped create the twin towers of steel and now were removing the beams that had melted into unnatural shapes.

Omg, thank you: you have finally proven gravity. Well done. The weight was more than enough. We have your word. Case closed.
there was a cloud of white smoke that came from the base of the towers just before they fell. thermite leaves white smoke.

See.... Now was that hard? I bet it wasn't as hard as you thought it would be... well done!
Steel is just the element iron that has been processed to control the amount of carbon. Iron, out of the ground, melts at around 1510 degrees C (2750°F). Steel often melts at around 1370 degrees C (2500°F).

I'm only leaving two holes open for this arrowhead project. Charcoal needs very little air supply to reach the high temperatures needed for forging and heat treating. ..............

When coal was discovered it was found to produce a hotter fire than charcoal. As coal begins to burn, all of the various impurities (tars, oils, sulfur, various trace elements and gases, etc) are burned off, and all that remains is pure carbon. During this process smaller pieces of coal will clump or stick together in larger chunks. The product of this initial burning process was historically called "coal charcoal", but is more commonly known today as coke. This lightweight substance ignites rather easily, and burns hotly - with a forced-air draft it can reach temperatures approaching 4000 degrees Fahrenheit. It was also found that coal charcoal (coke) fires left unattended would die out rather quickly, leaving unconsumed fuel which could be used in subsequent fires. Coke lumps can be glowing on the underside, yet remain relatively cool on the top side. The topmost layer of coke on a forge fire acts as an insulator, holding in the heat from the fire beneath.

* The direct method uses heat from the incomplete combustion of the organic matter which is to become charcoal. The rate of combustion is controlled by regulating the amount of oxygen allowed into the burn and is stopped by excluding oxygen before the charcoal itself begins to burn. This is the ages old method used by colliers to make charcoal in a pit, pile (clamp) or, more recently, in metal or masonry chambers (kilns). See the links below for more information.
* The indirect method uses an external heat source to "cook" organic matter contained in a closed but vented airless chamber (retort). This is usually carried out in a metal or masonry chamber (furnace). The indirect method results in a higher yield of high quality charcoal with less smoke and pollutants and requires less skill and attention than the direct method. www.velvitoil.com...
Charcoal burns at the necessary temperature (2012 degrees Fahrenheit / 1100 degrees Centigrade), and was therefore used locally in the smelting of iron from as early as 450BC right up until coke became available in the 18th century.
