Ok...28th... just so I can understand what it is you think is happening...
When the outside supports fail (you do admit they do, yes?), and a few floors as well (you do admit this also, yes?), what remains is (this is the part I really want to ask you) A) how many floors above the failure point?, supported by B) how many columns (that is, do you accept that any were damaged by the plane and fire, or do you think they were undamaged?), C) for what distance are these columns deprived of their necessary bracing by the floors and outside supports?, and D) is the mass in A static or moving?
Each of these four are very important, I am sure you will agree. A) determines whether the columns are holding up a light, moderate, or tremendous load, B) determines the strength of the thing that is holding it, C) determines the leverage the weight has (try snapping a long pencil, then try snapping a 2-inch pencil stub--hard to get the leverage to do the latter, isn't it?), and D) will deliver that load evenly or unevenly upon the columns in B).
My thoughts are that A is sufficiently massive, B sufficiently damaged, C sufficiently lengthy, and D sufficiently moving, that catastrophic collapse happened almost instantly.
What are your thoughts? I honestly want to know what you think is happening.
