Creative Speculation

No, I'm not agreeing with your vaguely worded description of debris scattering, nor will I until you state your claims much more precisely and then clearly state what you conclude from them.

Yes, the columns got thicker. Now, do you agree that as the collapse progressed, more and more mass was falling faster and faster? And do you agree that the equation E_k = 1/2 mv² describes the kinetic energy of that accumulating m and accelerating v?

And do you agree that column buckling was not the predominant failure mode, anyway; that the primary failure mode was floor framing being ripped away from the columns? And do you agree that, unlike the columns, the floors weren't progressively stronger going down the building; that they were the same on every floor except for the mechanical floors?

So, wouldn't you agree that your argument doesn't yet seem to be heading any place relevant to why anyone should believe in magical silent explosives?
