🧵WTC collapse simplified. The reason the Twin Towers were the "first-ever steel structures to collapse like they did"…

Summary

This thread explains the collapse of the Twin Towers on 9/11 using structural engineering: the buildings' unique design used floor trusses connected to outer walls and inner core columns. When fires heated these trusses, they sagged and snapped, causing a progressive collapse of floors. The thread addresses conspiracy theories by showing that controlled demolition theories lack physical evidence and contradict observed events.

Summarized by ThreadOut AI from the full thread. May miss nuance — read the thread below.

    🧵WTC collapse simplified. The reason the Twin Towers were the "first-ever steel structures to collapse like they did" is because none in the world were built like they were, nor attacked like they were. Each floor was held up by trusses attached to outer walls and inner cores.

    All that was securing each floor to each side and holding them in place were these components.

  3. #3

    Here's an actual picture of the trusses and how they attached to the outer wall, with a person to compare size.

    These were designed to maximize floor space, so all core columns were put in the center. This is the floor plan from the top view; the red circle shows where trusses connected to the inner core columns.

    Aside from the damage to the core columns, which the Twin Towers actually did their job and withstood, the fires were the biggest problem. Fires on several floors heated up the trusses until they sagged and eventually snapped, freeing floors to crash on top of the one below them.

    We saw this happening RIGHT before collapse. Notice the outer walls bowing inward like the animation above. Bomb theorists ignored this yesterday because they have no explanation. The reason is because right after they snapped, the collapse initiated.

    Here's a view of what happened inside once they snapped.

  8. #8

    As the floors collapsed down on each other with increasing weight, it led to total collapse. Notice we didn't SEE or HEAR any C4 explosives going off before the collapse. What about thermite? It can't sever all columns simultaneously; that's why it's never used in demolitions.

    In 25 years, 9/11 Truthers haven't provided a SINGLE working model. All they do, like Flat Earthers, is doubt certain aspects of NIST's and call everyone shills while providing no explanations or mechanisms to support their claims, thinking that questions alone debunk models.

  10. #10

    Here are MY questions: Why hasn't anyone found a single identifiable part of any kind of bomb—a blasting cap, wire, etc.? Where's the test showing thermite or nanothermate that wasn't debunked already? How does thermite silently melt beams while also blowing beams outward?

    The answer to each question is "checkmate." You can't have it both ways. You can't claim an incendiary acts like an explosive, or an explosive is quiet like thermite. It's physically impossible and doesn't match what we witnessed. Therefore, the demolition theory is false.

    If you want to argue that Mossad or whoever was behind 9/11, overseeing the operation in some unfalsifiable way that you can't even prove to yourself—be my guest. But stating your beliefs as facts and calling people shills when you can't verify them to yourself is delusional.
