Sound Evidence for Explosions....

10. You'd better produce some audio of the invisible collapse of 47 concrete floors.

No audio, no collapse, right?

Or do you employ differing standards so the lack of audio applies only to explosions?

I think we've already been over the thesis by which the walls of the hollow columns were heated with incendiaries and then explosive charges planted inside the columns would bulge out, but not breach, the column walls--resulting in buckling and column failure with little noise escaping.

But no explosives are needed at all. Thermite charges could rather easily cut the girder seats, which are only an inch or so thick. And they wouldn't make much noise doing it.
