For a very easy example of how this works stand on a soda/beer can, then poke it in the side with your finger. That's the exact reason the WTC collapsed, but planes were the finger.
It's basic architectural stuff... the structural integrity of both buildings was catastrophically compromised by the destruction of a section of the cladding, the fuel only operated to make things worse by weakening the structure further.
Fire had nothing to do with the WTC collapse, gravity did...

Is that simple enough?
Nice. Only took you two days to jump from a gravity-driven collapse to a gravity-driven collapse aided by fire. Big problems, though:
From the NIST report, 2005, pg. 127:
"The duration of temperatures near 1000 C was about 15 to 20 minutes. The rest of the time, the calculated temperatures were near 500 C or below."
NIST report, pg. 140:
"NIST contracted with UL to conduct tests to obtain information on the fire endurance of the trusses like those in the WTC towers...all four test specimens sustained the maximum design load for approximately two hours without collapsing."
Say goodbye to the pancake theory.
Regarding the jet fuel:
NIST, pg. 179:
"The initial jet fuel fires themselves lasted at most a few minutes."
Occam's Razor:
Controlled demolition has imploded hundreds of steel skyscrapers.
Fire and gravity and plane impact have never demolished a steel skyscraper on any day but 9/11/01 ( according to the government theory ).
Therefore, Occam's Razor points to controlled demolition as the most likely hypothesis.
