Creative Speculation

... so we're just looking at the exeternal skin? And the perimeter columns somehow pulled away from the skin without distorting it? Then how come the perimeter columns stay standing in the model?

Are you claiming that the curtain wall stood with no support in a NW wind when the columns it was hanging from had been removed?

You're not interested in hypotheses that fit the evidence--perhaps better than your own hypotheses. You prefer to discard them with a dismissive label.

You really can't imagine why "they" would hypothetically cut the floor beams on the 46th floor to cause the penthouse collapse? You really haven't thought very much about these things, have you?

No silent explosives are needed. If explosives were planted inside hollow core columns, and the column walls were heated with incendiaries, a relatively small charge could cause the columns to buckle without breaking the walls of the column so the sound would remain contained.

You didn't answer my question. Do you have any audio of the sound of 47 concrete floors collapsing invisibly inside WTC7? Why not? Do you think that would have been silent?
