Don’t follow. If WTC dust didn’t come from WTC buildings, then where did the dust come from. Pixies? Dust bombs?
No you don't. The thought that it took months of preparations to demolish the WTC buildings is too much to comprehend. The though that the US government planned, prepared and executed the events on 9/11 is just too much too consider. Why would the government want to kill it's own population? It does not make sense to a reasonable person.
When Trump says he wants to drain the swamp we are not dealing with reasonable people. We are dealing with psychopaths who do not care about you. They only care about themselves.
Do you really think it is appropriate to compare a bricks and mortar building to a steel and concrete one?

So. Still no physical proof of columns actually cut to initiate collapse.

Well Ok let me put it to you this way. Most, if not all, regular CD building demolition collapses are done from the bottom. A slight variation being your explosiveless hydraulic jack example. But using explosives they take out the bottoms. Is this false.

So. You have no real explanation what initiated collapse. Like cut columns for example.
Now, you show a pic of lightning hitting the antenna of the north tower, again, I don't know why.
Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves, causing the instantaneous release of as much as one billion joules of energy.[1] This discharge may produce a wide range of electromagnetic radiation, from very hot plasma created by the rapid movement of electrons to brilliant flashes of visible light in the form of black-body radiation. Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. Lightning occurs commonly during thunderstorms and other types of energetic weather.

There's Way More Energy in a Bolt of Lightning Than We Thought
www.sciencealert.com...
Power is energy per time, and our measurements of fulgurites suggest that megajoules of energy make rock in thousandths to millionths of seconds. So a gigawatt is actually on the low side – lightning power may be a thousand times that, reaching into the terawatts, though the average is probably tens of gigawatts.
That’s enough energy to power about a billion houses, albeit only for a few millionths of a second. Unfortunately, given its sporadic and unpredictable nature, no power grid will ever be able to harness lightning effectively.
But with that much power, perhaps breaking the space-time continuum in a souped-up Delorean is not so unfeasible after all….

Can you cite any evidence that supports NIST's conclusion that gravity and office fires caused the collapse?
There is ample evidence that contradicts the NIST conclusion. Are you interested in discussing it?
Failure of Welded Floor Truss Connections from the Exterior Wall during Collapse of the World Trade Center Towers
app.aws.org...
Summary
Analysis of the connections supporting the composite floor system of the WTC towers showed that at and below the im- pact floors, the greater majority (above 90%) of the floor truss connections were either bent downward or completely re- moved from the exterior column. This was probably related to the overloading of the floors below the impact region after col- lapse initiation. Depending upon weld joint geometry, detachment of the main load-bearing seats was a result of either fracture in the heat affected zone of the base material (standoff plate detached from spandrel) or through the weld metal (seat angle detached from standoff plate). Failure in both cases was assumed to be a result of a shear mechanism as a result of overloading from floors above impacting those below. There did not appear to be a significant change in distribution of failure modes of the floor truss connections when comparing those connections inside vs. outside of the impact region or those ex- posed to pre-collapse fires and those that were not.

the plane 'knocked off the fire insulation'.
That is the funniest thing i have heard in a while , i saw a picture from inside the walls of the insulation , same type i used to apply many years ago , We called it bubblegum because it stuck like hell and was murder to grind away when any welding had to be done .
No way hosey
you don't know the plane 'knocked off the fire insulation'.

Purdue creates scientifically based animation of 9/11 attack

Still, Popescu says the visualization has a realism never seen before.
"The crashes and computer models you often see on television are not scientifically accurate," he says. "This provides an alternative that is useful to the nonexpert but is also scientifically accurate, so it provides a more realistic picture of the event."
"This translator is scalable and can be used in other simulations," Popescu says.

Aircraft Impact Damage
web.mit.edu...
Depending which case considered in Table 2 will be valid, the number of destroyed
core columns in South Tower will vary between minimum of 7 and maximum of 20. It should be noted that the prediction for the North Tower would be different for two reasons. First, the impact velocity is smaller and hence the kinetic energy induced by the airplane is less. Second, the airplane impacted the tower on different side correlating with the core structure orientation, so that the energy dissipated by these longer floors was larger. Taking the each of the factors above into consideration, the predicted number of damaged core columns in the North Tower will vary between 4 and 12. There will be an enormous difference between the ways in which the global collapse was initiated in both towers. Effect of the local damage on the global collapse of each tower is discussed next.

second analysis was conducted to estimate the demands on columns immediately following aircraft impact and before fire effects occurred. Exterior columns were removed from the model to match the damage pattern illustrated in Figure 2-27. Although some core columns were probably damaged by the aircraft impact, the exact extent of this damage is not known and therefore was not considered in the model.
The Truth is you do not know for sure.
Do you or do you not know the plane knocked off the fire insulation?
A seemingly necessary one (for you) that backs up the collapse due to fire narrative like a talking point, for if that didn't happen then what really weakened the steel? Right? And what really destroyed the towers? Can't have random people wondering those things quietly to themselves or loudly to others.
No we have to tell them how it was step by step. Over and over and over.
While reading your 2 paragraph step by step story line I was reminded of this guy, yet another guy who had a set story but also no concrete evidence, really, to back it up. He's just some guy on a street corner telling you A Story. He even calls it 'ground zero' if you can believe that. He's probably the first to do so actually. Interesting.
You see the narrative was already invested in a plane, jet fuel and office fires. Can't very well have someone come along and say "Yeah, BUT there was fire insulation..." now can we? No.
FIREPROOFING” AT THE WTC TOWERS
www.fireengineering.com...
BY ROGER G. MORSE I investigated the fireproofing in both World Trade Center towers over approximately a 10-year period between the early 1990s and early June 2000, the last time I was in the towers. There were problems with the fireproofing in the World Trade Towers that may have rendered them vulnerable to fire.
So, 'the plane knocked off the fire insulation!'
Must've happened right? Sure. That's the ticket. You don't sound like a 9/11 investigator spouting off that nonsense you sound like some hack B movie script writer. You realize that right? 9/11 ain't Titanic or the Poseidon Adventure.
Just because there was a plane, jet fuel, office fires, time, bowing and what you think/believe is a building 'collapse' etc.
Doesn't mean there was.
All that's not Evidence that is make believe hole filling after the fact. It's not really evidence based it's more akin to wishful thinking and even DREAMING stringing that totally implausible story along. You're due for a rewrite. Nobody is buying the fire insulation tale.
Just admit, that you do not know.
That is all.
