I meant F.
And all fires have hot spots. In one building there was molten metal seen dripping out of one corner, where a majority of the aircraft had ended up. This is logically aluminum, and the melting point of aluminum is around 1200 degrees F. A few hours of that near supporting beams, and all that was required is to lower the material's strength, not even get it glowing hot. We see plenty of examples of buckling sides before the collapse, and eventually one failure multiplied.
Is everyone supposed to be impressed?
I presume you do not expect people to research what you say. They are just supposed to take you word. The fuel will only get to very high temperatures in a controlled burn where the air is properly mixed with the fuel. That will only happen under controlled conditions like in an engine or foundry.
So according to the data for which I provided sources it will not raise the temperature enough for the metal to even glow in the dark.
So the floors with trusses you talk about are not subsystems?
After all of these years shouldn't the experts be able to tell us the tons of steel and tons of concrete that were on every level?
As an example of one of his falsehoods it is fairly easy to find how much concrete was in the Towers above ground.
One floor was an area of 208^2 feet=~40,000 square feet. The core was 138 by 78 or ~11,000 square feet. The concrete on the floor trusses was 4 inches(a third of a foot)deep giving us ~10,000 cubic feet of concrete on each of 86 floors at 110 lbs per cubic foot gives us about 5000 tons in the floors for each of the 86 floors which were identical in construction. The cores were 2/3 elevator shafts so it had 3500 sq ft of 6 inch normal concrete at 160 lbs per cubic foot gives us 272,000 lbs for a total amount of concrete for each floor of about 5236 tons.
Mechanical floors were easier, just multiply area(~40,000)times depth(.5) gives 20,000 times weight/cu ft(160) equals ~3.2 million pounds or about 16,000 tons(times three mechanical floors).
There was about 500,000 tons of concrete in either tower above ground, only about 50,000 of it structural.
That is the total of all concrete above the ground floor and with a little intelligence the distribution can be easily derived as well. Why couldn't psi get these results despite all his years of searching? Because he considers keyword searches to be thinking.
752 degrees F is still well within the range of temperatures that are possible in a fire. In fact I have read that 1000 degrees F is not at all impossible.
Did you miss this, or just ignore it?

And...we're back to the concrete. Deja vu.

So your claims that in all those years nobody knew how much concrete and steel was in those buildings is a lie, whether your math is correct or mine is those facts can be discerned by any competent mathematician(which I make no claim to be).
And what is the specific heat steel?
And how many tons of steel were in the fire?
Don't you love how Grumpy gets his data and math all wrong, but then you would not have noticed.

sorry to interrupt. things have gotten a lot more serious:
Looked right to me. He didn't have any small mounds of paper and washers to represent the frame of an enormous building with completely different dynamics, though.
An earlier report on Digital Journal found that the claims made in the documentary can be verified by reading the government reports themselves. The National Institute of Standards and Technology (NIST), the government agency charged with the investigation, did not provide any data -- no measurements or estimates -- of the mass or energy that would be required to bring down the buildings in about ten seconds. Normally a scientific report would present all the data that is used to construct a theory. The omission of data is a red flag to anyone familiar with scientific procedure. It appears that the investigators may have intentionally produced reports that the scientific community would reject.
Yes, infowars has nearly reached critical mass in the echo chamber, prepare for the shock wave when all the Troother's heads implode simultaneously.
