The WTC complex was on a plaza that is like 15 acres. It's a big space. Multiple buildings were on that plaza. The towers collapsed on those buildings.
WTC 7 is not even on this plaza. It across a city street from the plaza. Debris from one of the towers fell onto WTC 7 and took a chunk out of the corner of the building.
I have. That's happening at the very end of the collapse sequence
I remember when Small Change came out I found it very persuasive. Especially on WTC 7, but a friend and I started discussing it and we found it was highly manipulative.
When you see the VIDEO EVIDENCE of WTC 7, there's a couple of things to note.
We don't see the bottom half of the building. This is where the collapse is believed to have started. The bottom half of building is blocked by other fairly tall buildings in NYC
The second thing a lot of sites don't show you the full collapse sequence, just the end. When you look at the full collapse sequence, you see all sorts things happening on one side of the building, then on the roof and THEN the building fully goes down.
As for the free fall.
Imagine two 12 foot ladders next to each other a few feet part.
Now imagine you stack them up 10 of these on top of each other. So you have 120 feet of ladders side by side
These wouldn't be able to stand up by themselves.
Now imagine for every 10 feet the two sides are connected to each other So one stack of ladders next to another with 12 connections running between them. Now you have a structure that can stand because these connections form a lateral brace where each ladder stack supports the other.
Now imagine there's structural failure towards the bottom of the ladders. A failure that starts ripping out the bracing from the bottom to the top. Once all those lateral supports are gone, the ladders are going to go down.
This is similar to what happened in WTC 7. It was built with a tube in tube structure.
So you have a inner box and outer box, but each box needs supports from the other.
So how's that affect my ladders. When basically imagine you can only see the outer ladder. The free fall collapse occurs after the inside ladder has fallen and all the supports are gone. And the video is only looking at the top of the ladders.
So where's my evidence for this? Does my metaphor stand up?
Here's a gif of the full collapse sequence. Is there evidence of some sort of interior collapse.
YES. Look at the roof. Something on the left side of the roof collapses INTO the building. Notice all the windows that start to break on the left. Then on the right.

The second thing to note is WTC had like 50 floors. It was over 700 feet high. We don't see all 50 floors here. Unlike 1 or 2 we don't see the point of collapse. It's blocked by other buildings.
Also fact about WTC? Hours before it collapsed the NY Fire Department cleared a collapse zone around it. Because they started seeing creaking metal and noticed earlier in the day, one of the corners of building started to bulge.....this is a sign of structural failure.
This argument is bogus completely. It is full of gratuitous complexity so as to hide the simplicity of the conservation of energy argument that I give elsewhere on this page. No amount of complexity can change the fact that, to quote the head of NIST at the first press conference after 9/11 "a structure cannot undergo progressive collapse at free fall".
A building does not naturally fall into a neat pile within its own footprint.
The towers did not fall into their own footprint.

WTC 7 is not even on this plaza. It across a city street from the plaza. Debris from one of the towers fell onto WTC 7 and took a chunk out of the corner of the building.
Have you watched the VIDEO EVIDENCE of Bldg 7 collapsing at free fall acceleration??
Please explain how this can happen without human intervention! I’ll wait.

You can see that here. It's the one that looks like a box with a box. it's described here as a core tube is surrounded by an exterior tube that interact horizontally. https://theconstructor.org/architecture/tube-structural-system-types-features/560166/
So you have a inner box and outer box, but each box needs supports from the other.
