It does not matter what the alternative was, because at this point it is mere speculation.You know damn well what I'm talking about. You're too much an intellectual coward to answer it.
This entire charade that you people put on is based on your laughable notion that aircraft impacts + fire could not cause those buildings to collapse.
Yet you people have never put forth a coherent alternative that takes into account the entire day's events. Not one of you. It's been almost 15 years!!
The buildings collapsed. That is a fact.
What explains the motions observed during the collapse? Hmmmm?
