I made this comment to a post earlier today, but I thought it was worth its own post. I can't believe I had never looked this up before. Am I missing something? A jet engine is OPTIMIZED to burn jet fuel the most efficiently possible. Jet fuel burning in a building fire is NOT GOING TO BE ABLE TO REACH THAT TEMPERATURE! (and even that would not melt steel!) This discrepancy, if as simple as it appears to be, should have been broadcast loud and far long ago. Perhaps this simple fact, if indeed as simple as it seems to be, so clearly indicates the official 9/11 narrative absolutely can't be true, is the reason it seems to have been buried all these years. Please correct me if this is not as simple as it seems.

Not enough heat was ever generated to make steel columns of that mass fail. And even IF enough energy had been provided, failure wouldn't have happened uniformly at the same time in any inferno.
Some historic fires burned for 8-10 hours on thinner steel structures, became much hotter as well, and no collapse ever occured, not even buckling. The heat hypothesis doesn't hold water. The twin towers were also massively overbuilt. https://steemit.com/wtc/@lighteater/another-steel-framed-tower-block-remains-standing-after-a-major-fire-unlike-on-9-11
Steel doesn't suddenly go from super hard to complete failure. It fails gradually as it heats up.
The crushing of floors below means that there is no cumulation of force... and everybody knows the same mass was easily supported by the floors below for decades.
Thermite was indeed provenly used, and there goes the narrative.
Well, our level of disagreement is that you don't want to admit any arguments from engineering, chemistry or physics. You make assertions that you at least cannot back up with any calculations. And you don't take into account the virtual certainty that aluminum was burning as well as kerosene. Aluminum is ferocious hot, giving off a lot of heat energy. And, regardless of temperature, when a material is exposed to a greater than limit load, it fails. It does not valiantly resist. That is why it is called a failure level of stress. You completely blank out the effect of momentum in creating high levels of compressive force. Have a car run into you and find out what all that momentum can do to your boy. Thermite was not "proven" to be used. All they found was the combustion products of burning aluminum, some molten metal, and sulfur from the gypsum drywalls. You have shut your mind to a new thought.
There was never any more compressive force on the intact floors than the intact building created from day one.... Plus some falling momentum, which pretty much got cancelled at every floor that resisted its crushing force. This should be obvious to someone seemingly as versed as you in physics.
Nanothermite was found and proven chemically.
That was made very clear in a peer reviewed paper which was cited numerous times in the truthseeker movement. You either haven't done your homework, or have shut your mind to the truth.
This is where you don't understand momentum. Reducing it by any amount in a finite time interval results in a force. Drive a truck into a wall at 60 mph and either or both will wind up being smashed by compressive force. No gravity involved. The falling momentum never got canceled; it was at least restored by another floor's height of falling and addition of falling mass.
This is not a matter of anything being obvious. This is a matter of F = p / t and calculation where p = mv. The whole down-falling force at impact is the sum Ftotal = m (g + v/t), where g is the acceleration of gravity.
I don't think you understand chemistry, either. The end result of thermite (nano or otherwise) is aluminum oxide and iron. The end result of a fire in which the airplane fuselage (aluminum) is burning will also be aluminum oxide and iron. And leftover condensed aluminum microspheres. It is the SAME chemical reaction. I worked in rocket propellant chemistry. Burning aluminum is a primary rocket fuel ingredient. I will be willing to bet that none of these experts considered that the airplane fuselage was involved in the combustion. As it happens, I have been doing my homework for decades, and am open to a logical possibility that you have decided to be closed against.
Yes momentum definitely gets lessened as it deforms anything, plus the resulting heat.
"Unlit" nanothermite was also found and confirmed with mass spec.
The found microspheres were mostly iron not aluminium, and were generated by the intense sparking events that are at least 1000 degrees too hot for the current narrative.
