Actually, you didn't make it clear previously that you were speaking about the roofline on the east and west faces. You simply said east and west faces, both of which experienced column buckling. Thanks for clarifying though. Now at least I know specifically what you are talking about.
I guess what needs to be pointed out is that you are making one glaringly faulty error in your assessment. The NIST model does not incorporate the building facade, which was made from red granite, for purposes of clarity. The model shows how the actual columns buckled, not how the facade went down. Because of that you aren't going to see represented in the video that which is shown in the models unless you could somehow magically strip away the facade.
Ok, I thought it was obvious but If you didn't then I'm happy I clarified. The SIM ends where it does and I don't recall if any lower floors also were 'warping' in-wards.
The facade or in my terms fascia [that may be different stuff for all I know] are connected to the exterior columns from what I read.. but I will revisit that element and IF I can see that the whatever it is called - the exterior - is not connected to anything that is doing the twist then I'd have to reconsider.
My simple mind says, however, and before I go digging for my answer, if it ain't connected what kept it up? And/or, if the twisty bit separated from the exterior stuff why don't I see that and why don't the exterior fall or crumble or something...
What I think I understand you to say is: This facade from the top down to where I can't see it in the video stayed up until after all the interior and exterior columns fell and then it came down nice and organized like where it finally (as I can see in the video) bent over toward the back or front depending on which view it is... [I think it is a looking south view if I remember which building is where.] Anyhow.. it bent over as a block.. the South face and the East face as a unit bent or what ever the term is... 'took a bow'.. but stayed bowed.. AND since I can't see over to the West face looking at the South face I'm not concerned with that bit.
