I'm having a hard time believing all that dust in the various pics and vids was clinging to vertical columns.
And just when did it have time to settle on them?
And in the immediate aftermath of a maelstrom?
Have at it...

The question remains: why did virtually all vertical steel components on that day follow gravity, i.e. straight down, instead of toppling?
Answer: No resistance. There are only a few ways that I can think of to achieve this. And structural damage and fire aren't them.

Griff... you know physics is not my specialty...I actually was a little curious as to how this could happen and asked some questions...Point is, gravity pulls straight down. The debris that fell surrounding the core no doubt damaged the columns near the bottom. all that would have to happen is a load transfer to adjacent columns and they would fail progressively. since the core is a hollow grid of columns and not solid like a tree. there exists no fulcrum to support the core long enough for it to fall sideways. anything that would even momentarily hold as a fulcrum would instantly fail as its load was multiplied by failure of adjacent columns.

sorry guys but the dust on the top of the structure while it disappears seems quite a bit to be simply falling.
Also but I am not sure on this one, isn't the steel bending? check the first and the second picture.
Damn 911 its getting weirder and weirder.

That’s actually exactly what happened. ...
