Can you please break that down to a ratio that makes sense. Gallons of something flammable to the weight ration of a building is not a comparable item. Break down the amount of energy released by the jet fuel along with the square footage of the area it hit along with the melting point with that area of steel and come back and post, please no copy and paste as I would like to see your long math on this.
Thank You
This is a good question. Even rough calculations of heat content of the fuels versus the amount of steel show nowhere near the amount of fuel required to soften that much steel. If the official story is true then it revolutionizes the foundry business, which spends lots of money on blast furnaces which burns lots of expensive coal or coke (refined coal) in an enclosed ceramic chamber, into which pre-heated air is "blasted" through the fuel to raise steel to 5,000F to melt, and maybe 4,000F to make malleable enough to work.
The fires in the towers never reached higher than a little under 500F according to
NIST's own report, which is the temperature of normal office fires. This is backed up by the firefighters' radio transmission that they were looking at
"isolated pockets" of fire that they could "knock down" (put out) with "two lines" (hoses.)
10,000 gallons of kerosene (jet fuel) has a maximum heat content of about 1.3 billion BTUs (One gallon contains 135,000 BTUs x 10,000 gallons)
http://www.hrt.msu.edu/Energy/pdf/Heating Value of Common Fuels.pdf
Carbon steel has a specific heat of .12 BTU/lb. That means it requires .12 BTU of energy to raise one pound of it by one degree F.
Specific heats:
http://www.engineeringtoolbox.com/specific-heat-metals-d_152.html
So lets say you wanted know how many BTU it would take to raise the temperature of just the steel in the upper 15 floors, above the points of impact, to say, 2,000F. That is still far short of 5,000F at which steel melts, and this is neglecting that since steel is an excellent heat conductor, the steel frame would conduct the heat energy throughout the frame. All of it could not just stay on 15 floors.
Since the steel frame is about 96,000 tons of steel, including core columns, and load-bearing perimeter columns, 15 floors would contain roughly 15/110 x 96,000 tons = 13,000 tons
In order to raise the temperature of 13,000 tons of steel by 2,000 degrees, it would require:
.12 BTU/lb x 13,000 tons x 2,000 lbs/ton x 2,000 degrees = 6.2 billion BTU
Again, since kerosene contains 135,000 BTU/gallon and there were maximum 10,000 gallons (half loaded) in each plane, the kerosene (jet fuel) could only produce 1.3 billion BTU under the most favorable conditions. 6.2 billion is greater than 1.3 billion. It's not even in the ballpark.
We are assuming that not one drop of it blew out in the fireballs, that it all stayed in the building, and that it burned at maximum efficiency in an optimum fuel-air mixture, which was not true. Kerosene only burned this efficiently in a jet engine, where the fuel is made into aerosol, compressed, and ignited in an oxygen rich mixture. In open air fires much of it is lost in soot and carbon by-products, called a "dirty" burn.
All that is back of the envelope stuff. A more extensive set of heat calculations by a professor of physics is here:

These are all good questions but still beside the point. We know fire can melt steel or make it soft. That why there have been partial collapses in high-rises and why fireproofing is used, to inhibit these partial collapses. What makes the official story ultimately impossible is that, even if the steel did get soft and bend, the mass could not have accelerated to the ground at the same speed it would fall through thin air. Steel is denser than air, even soft steel.
The lower 90 stories would have absorbed energy and slowed it, not added to it and increased it. Mass does not go faster as it accumulates/gets heavier. This is what Galileo proved.
We also know that the towers were specifically designed to take multiple hits from planes the size of 767s. The largest plane flying at the time of design was the 707. From the design engineers' parameters here:

A 9/11 Story Problem: Which 15 story building hits the ground first?
http://www.naderlibrary.com/911.blueprintfortruthae3.htm
Answer: On 9/11 both upper blocks hit the ground at virtually the same time, suspending the laws of physics!
-If the 15 story section is falling at free fall speed ...
-All of its gravitational potential energy is converted to Kinetic Energy (movement)
- It is not available to do the work of "crushing" the building below!
- It would have to slow down in order to do any other work, i.e., "crushing 80,000 tons of structural steel below.
As a side note everyone should know that it is 9/11 families themselves who are asking for a new investigation. This is an ad running on NYC cable television. Are they all tin foil and crazy?
