But the only issue to clarify, first of all, is to prove that such a collapse, from only random fire/damage, is impossible. It cannot happen, in any way
The Plasco Building (Persian: ساختمان پلاسکو, romanized: Sâxtmâň-e Plaskô) was a 17-story high-rise landmark building in Tehran, the capital city of Iran. At the time of its construction in the 1960s it was the tallest building in Iran[1] and was considered an iconic part of the Tehran skyline.[2] The building collapsed on 19 January 2017 during a high-rise fire.[3]

Massive high-rise fire causes building to collapse in Brazil, at least 1 dead

A massive fire engulfed two high-rise structures in Sao Paulo, Brazil, on Tuesday, causing one of the buildings to collapse.
Video posted on social media early Tuesday showed a 24-story building crumbling to the ground as flames raced toward the top floor, killing at least one person.
THE FIRE AT THE TORRE WINDSOR OFFICE BUILDING, MADRID 2005

Consequential damage
In the absence of any protection the mullions weakened in the heat. A sufficient number lost their required load capacity causing sections of the building above the upper strong floor at level 17 to collapse. It is likely that only the presence of this floor prevented total progressive collapse. At lower levels none of the fire protected mullions failed. The mullions distorted at the 9th level (yet to receive their protection), but there was sufficient load sharing amongst the remainder-above and below this level- to prevent collapse of the floors. Notwithstanding the failure of the mullions, the reinforced concrete structure also suffered serious damage as a consequence of the temperature attained.
Shame on you for claiming such blatant falsehoods in the first place!
Your claim is so ridiculous, on any level, to keep spewing it, is truly shameful, and repugnant.
The Plasco building was another CD.

You
The Plasco building was another CD.
Base on what evidence.
It’s a truth movement lie to keep the CD fantasy on life support for blind followers of WTC controlled demolition.

So. You have no citable evidence of WTC CD. And you have to lie about the Plasco building collapse. Got it.
Puffs of smoke coming out of the building, moments before the collapse begins, is a common feature of a CD.
The immediate loss of all structural support is another CD feature.
The speed of collapse is another feature.
3WHAT ABOUT THE ALMOST FREE-FALL COLLAPSE OF THE TWIN TOWERS? The key is the “almost” modifier. If I told you I was making almost $100,000 and you found out I was making only $67,000, you’d say I was exaggerating. So stop exaggerating the collapse speed of the WTC Towers! The 80,000 tons of structural steel slowed down the collapses of the Twin Towers to about ⅔ (two-thirds) of free-fall.3 And the core collapsed at about 40% of free-fall speed, coming down last.4 According to Richard Gage: “To bring a building symmetrically down, what we have to do is remove the core columns.” But on 9/11 the stronger core columns came down last, which violates this supposed most fundamental rule of controlled demolition.

Claiming they were not CD's, isn't based on reality.
Puffs of smoke coming out of the building, moments before the collapse begins, is a common feature of a CD.
The immediate loss of all structural support is another CD feature.
The speed of collapse is another feature.
These are common features of a CD collapse, which appear only in CD collapses.
Because no other collapse has occurred like this, EXCEPT for CD's.

You mean smoke from fires? With no indication of explosions with the force to cut steel columns as in no corresponding audio of explosions? No evidence of a pressure wave / pressure transient with the force to cut steel columns. No corresponding splintered steel/shrapnel being ejected? No corresponding seismic evidence?

There is evidence and accounts all three buildings were in distress and leaning before collapse
For the twin towers. They leaned. The sides bowed in and buckled.
The twin towers, the core columns fell last.
Please actually quote the total collapse time from the first sign of buildings shaking / leaning until total collapse.

Puffs of smoke coming from one side of building is indication of interior structural collapse
As are
Booming or crashing sounds from inside of building
Windows breaking
Doors either swinging free or jammed tight
Water pouring out one side of building
Cracks appearing in building
All are signs that building is becoming unstable and of impending collapse
So my instructors at seminar on building collapse told us what to look for
All were FDNY chief officers who were at WTC on 911
No, I mean puffs of smoke expelled from a building where there is NO fire, and NO damage.

Failure of Welded Floor Truss Connections from the Exterior Wall during Collapse of the World Trade Center Tower
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.

And that floor connections were bent or sheared by a falling mass from still standing vertical columns. Showing with the video evidence the floor system failed first. The vertical columns were the last to topple. And the twin towers did not collapse through the path of greatest resistance.

This is the difference between you and me. I will take a claim. Like the collapse speed of the buildings. I will try to read as many sources as possible. Look at as much analysis as possible. Compare and contrast. Compare it to the video available on line. I will base my arguments off proven analysis. And cite that source in my argument.
You. Well. You literally make up crap. And use proven lies.
