Creative Speculation

(11,777 posts)The curtain wall panels are called that because they were hanging from the columns and beams, so they were not structural elements. But they were rigid enough to carry considerable wind loads to the columns and beams, and apparently they were rigid enough to hold the box shape as they collapsed. They are omitted from the simulation but they are the ONLY thing we can see in the videos, so there is no rational reason to expect the exterior columns alone to LOOK like the videos when they collapsed. You do understand that the purpose of the simulation was to simulate the physics of the STRUCTURE, no?
And I'm not interested in ad hoc "just so stories" -- non-explanations that amount to saying "they" did that to the penthouse so it would look like it did. So yes, if you can do better than that, have at it. And I'm still anxious to hear why "they" blew out eight floors after the building was already falling. Bonus points for identifying the magical silent explosives.
