www.fema.gov...
The large quantity of jet fuel carried by each aircraft ignited upon impact into each building. A significant portion of this fuel was consumed immediately in the ensuing fireballs. The remaining fuel is believed either to have flowed down through the buildings or to have burned off within a few minutes of the aircraft impact.
" The heat produced by this burning jet fuel does not by itself appear to have been sufficient to initiate the structural collapses. However, as the burning jet fuel spread across several floors of the buildings, it ignited much of the buildings' contents, causing simultaneous fires across several floors of both buildings. The heat output from these fires is estimated to have been comparable to the power produced by a large commercial power generating station. Ove ra period of many minutes, this heat induced additional stresses into the damaged structural frames while simultaneously softening and weakening these frames. This additional loading and the resulting damage were sufficient to induce the collapse of both structures."

I'm curious why you didnt finish that paragraph.....allow me.

Yeah.....heat output comparable to the power of a large commercial power generating station....yep, sounds like a "normal office fire" to me.
Plus, it still shows that you were wrong when you said a majority of the fuel burned up OUTSIDE of the building. It clearly states a significant amount...but not a majority. Most fuel was consumed INSIDE the structures.
[edit on 4-11-2007 by Disclosed]
So the engineers who designed the towers to "withstand multiple impacts of jet liners" would not have considered all that fuel as a factor?
The results indicate temperatures of 800 to 1000 °C, and a burning rate of about 15 to 30 kg/s. As mentioned before, it is quite possible that the temperature could have exceeded those values estimated here. For wood (15 MJ/kg) at 560 MJ/m2, the burning duration of the office furniture can then be estimated at about 86 to 171 minutes. The towers collapsed in 56 and 104 minutes. 19

You might want to go back to school and learn what Significant means.
In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, Figure 6-36).
However, when bare steel reaches temperatures of 1,000 degrees Celsius, it softens and its strength reduces to roughly 10 percent of its room temperature value. Steel that is unprotected (e.g., if the fireproofing is dislodged) can reach the air temperature within the time period that the fires burned within the towers. Thus, yielding and buckling of the steel members (floor trusses, beams, and both core and exterior columns) with missing fireproofing were expected under the fire intensity and duration determined by NIST for the WTC towers.

Well, lets see now. The FEMA report says appx 3000 gallons was burned in the fireballs....and left appx 4000 gallons to burn on the impact floors. This is directly from the FEMA report.
Battalion Seven: "Ladder 15, we've got two isolated pockets of fire. We should be able to knock it down with two lines. Radio that, Radio that, 78th floor numerous 10-45 Code Ones"
Within ten minutes of impact, smoke was beginning to rise to the upper floors in debilitating volumes and isolated fires were reported, although there were some pockets of refuge.

1. Firemen who made it to the 78th floor reports only isolsted fires on (NO LARGE JET FUEL FIRES)

So please tell me where all the jet fuel went to, if it wasn't burnt off on the EXTERIOR of the building?

Burned off within a few minutes of the impact. Igniting everything on each of the floors.

No, it did not ignite everything on each of the floors. Not according to the firemen on the 78th floor. Or are you trying to say the jet fuel ran up the floors instead of down?

You keep talking about the fires on 78. I asked about the fires on the floors above.

No, you keep talking about all the jet fuel that caught everything on fire on all the floors.
But yet the firemen who made it to the 78th floor saw only isoloated fires on the 78th floor, nothing below. So this proves that their was not that much jet fuel, and that it did not catch everything on fire below the impact area.
Also the 9/11 Commission report stated there were only isolated fires on the impact floors 10 minutes after the planes hit. No large jet fuel fires.
So you are proven wrong agaon about the jet fuel.

Why are you afraid to talk about the floors above 78? You DO realize that the 78th floor wasnt the only impact floor dont you?
Why do you think NORAD did nothing to protect the skies over America? During the time the airplane was coming in towards the Pentagon, there was a young man coming in, telling Cheney: "the plane is 50 miles out, the plane is 30 miles out" and so on. When he got down to "the plane is 10 miles out", the young man also said to Cheney:

No, i am saying there is no way there could have been 4,000 gallons of fuel (as you stated) left after the intial explosion becasue nothing made it down past the 78th floor.
Also none of the fire chiefs present believed the towers would completly collapse. They were only worried about the floors above the impact area might collapse if the the fires would have burned for several more hours (WHICH THEY DID NOT).
Originally posted by Disclosed
The 4,000 gallon estimate is the FEMA estimation, not mine. Plus, are you saying that floors 79-83....each 40,000 square feet.....could not dispurse that fuel?
Nobody thought the towers would collapse, period! However, the combination of the aircraft inpacts, plus resulting fires, started a chain of events that led to the eventual collapse. That is what is stated in the NIST reports (if you bothered to do any research).

What fuel flowed down? If the firemen on the 78th floor saw no fuel fires.
I was a crew chief in the Air Force and i worked with JP-8. So you do not need to tell me about jet fuel.
