I haven't read the entire thread word for word. I am generally well-read on things having to do with 9/11. I am familiar with the story, the story after the story, the story about the story, and multiple interpretations of the story. (I think there is a story about all those stories, but I digress...)
Here are the questions that occur:
If explosives were pre-planted, when did that occur? (Some obvious possible answers emerge..., and I'd guess most in this thread could cough up an answer or two.)
If we know or assume that nano-thermites were involved, when were those first available in functional applications, and to whom?
