The jet fuel argument refers to THE MOLTEN STEEL. Not the actual collapse

Angular momentum of the tipping top vanished.
To prove this for your self: Take a broom balance it upright on your hand. Allow it to start tipping. Remove your hand from underneath it. The rotation will stop and the broom will fall to the ground at the same angle it was when you released it.
Lol.. exactly.
The excersise you just described shows zero resistance, which is why the broom fell that way.
This is why the tower fell the way it did. The resistance was gone.
Should have toppled.
The building's design was more like a pop can then a solid broom or tree.
There really wasn't any "angular momentum".

How could all of the building’s 47 core columns fail uniformly given that the destruction wasn’t symmetrical when it started?

How long do you need to heat carbon steel at 2800 f to bend a beam
You don't need to even reach a temperature even close to that to bend a steel beam.
You can bend a 100,000 foot steel beam with only 500 degrees in a two inch portion of it.
Yes. You don't even have to heat steel to bend it, given enough force.

Almost all the kerosene fuel was consumed in the initial fireball outside the building. There is a picture of a woman standing ih the hole the plane made looks like the fire is out there,Paper carpet and desks don't melt or weaken steel-was a low temp black smoke fire firefighters said they could put out. How do you turn 32 acres of 4in thick concrete into dust? surely not with kerosene.

I can melt steel with a paper match.
I don't see why 10,000 gallons of jet fuel couldn't heat steel to the temperature where it would deform and lose its structural integrity in an office building with elevator shafts providing a passable chimney.
Thousands of gallons of fuel went down elevator shafts and burned on lower floors.
After the kerosene doesn't burn hot enough to melt steel argument fails, we find out that the kerosene burned outside of the structure anyway?
It doesn't matter anyway.
If you search the internet, you can find a lot of photos of twisted and deformed steel beams that remained after structure fires fueled by little more than painted wood.

1. Look how thin that piece of steel was, the I beams were much much thicker

Why did the central columns come down then, if what you say is true the floors would have collapsed but the columns would have remained straight and tall.
The floors are what held the columns straight and tall. Without the floors the columns buckle and fall.

True or false, steel losses 50 percent of its ability to resist strain at 1000 degrees Celsius?
www.purdue.edu...
Building fires may reach temperatures of 1,000 degrees Celsius, or more than 1,800 degrees Fahrenheit, said Amit Varma, a Purdue associate professor "
At that temperature, exposed steel would take about 25 minutes to lose about 60 percent of its strength and stiffness," he said. "As you keep increasing the temperature of the steel, it becomes softer and weaker."

NO COLLAPSE PULVERIZES 90% of solid steel into dust.
This personifies the truth movement,
How high do you think the rubble of two buildings of that size would leave behind? Where was the rubble - can someone show me a picture of the pile of rubble?

95 % of a room is empty air space . The rest was pulverized by the collapse into pieces no bigger than a foot
Below the WTC was a 7 story deep parking garage/basement
The compacted debris filled up the basement then piled up above ground where it was visible

I've seen something like this before.
While steel does melt at a much higher temp that what burning jet fuel can produce, the steel does not have to be melted to become structurally-compromised.
Good video.
