No, you are pretending that proof that trusses can sag is proof they can pull in columns.
Explained in the reply you keep ignoring. Here...
You have not supplied anything that says sagging trusses can pull in columns.
Now please stop before you hijack another thread.
The initial deflection rate matches closely. At about
250 s the deflection rate in the 2D analysis increases slightly.
This is the point in the 2D analysis when the column begins to
be pulled back inward by the deflecting floors. The deflection
rate then becomes more moderate at about 400 s as the rate of
heating in the steel reduces. Runaway failure is then obvious as
the building collapses.
Further analysis of results shows that this extra deflection is
caused by the failure of the column rather than further failure
of the truss. The column is pulled out of plane enough that
P–Delta moments cause plastic hinges to occur in the column
creating a mechanism. This then becomes a global phenomenon
and is outside the scope of this paper.

We may not know the details, but we do understand enough physics to realise we were lied to.....
And the most poignant and pertinent questions were NEVER ANSWERED by the phoney investigation.

Videos and witness testimony suggest explosives were used on the towers as well.

Are there any videos that unambiguously show explosives?
and there's no other collapse video in existence that exhibits these ejections other than controlled demolitions. You can watch controlled demolition videos all day long and see these ejections, which are a direct result of high-powered explosives being detonated.
In the following video, you can hear the pre-collapse and during-collapse explosives being detonated from 2 miles away:
There are plenty. Many of them first responders. It's also not about whether they back explosives or not. What they describe, along with all other evidence, can only be explained by explosives.
And as has been discussed numerous times, along with the above information, if steel-structured highrises could actually be brought straight down with fire, controlled demolition companies would be saving millions of dollars by using fire to bring the buildings down. But they don't, because you can't.
Steel-structured highrises can only be brought down by explosive demolition (or a very strong earthquake that exceeds the earthquake design tolerances), period.
Actually, we do. That's why some of those "kooky ideas" are in the hoax bin of this and most other websites.

Get 64,000 Kg's of explosives into each building. Requiring 8 charge relays per floor, over 150 miles of wire with a team of 18 experts 3 weeks to do the job consisting of over 600 cuts to the sub and super structure for placement of charges in a building that is never empty. Maintenance, security and cleaning staffs of 600 or more employees occupied both towers during non business hours. Complete radio silence for last 8 days of preparations. Forgetting, of course, that the micro-manager from hell John O'Neill was in charge of security.

Ejections coming out of both towers as they collapsed is proof of explosives because you can see those same ejections in most other explosive controlled demolitions. Why do I have to repeat this point? Why is this point so difficult to comprehend?
You cannot see those ejections in any other type of building collapse except for explosive controlled demolitions. I guess it's easier to deny this fact and make up something to explain the ejections away just for this one and only day in history so that one can remain in denial. But it doesn't make the previous fact any less factual.
There were no explosives on the outer walls.
Almost every camera recorded the initial explosions that initiated the collapse of the south tower. There are plenty of witnesses that heard the explosions from right next to the towers whether cameras picked them up or not.
And here we start diving into the disinformation pool, whether deliberately or ignorantly. Wind can't know to blow during each collapse, and for the duration of each collapse. Why one would even peddle this blatant disinformation is completely baffling.
At least one firefighter testified in the Oral Histories to nearly that exact number of pre-collapse explosions before WTC 2 collapsed. That means we have a witness. That means it's not wind.
That is not what I said, and changing what I said is dishonest. Especially when you quoted what I said.
My "views" are backed up by architects, engineers, scientists, physicists, and history.
Take yourself into the hoax bin and look for them yourself. I'm not going to do it for you.

Other than a couple of internet shills and editors at Popular Mechanics, the government would not dare attempt to refute these guys.
Some people have given into this idea that somehow the government's theories (progressive collapse vs. truss failure vs. column failure, the government doesn't even agree with itself) are automatically correct, why?
