I guess the Architects and Engineers for 9/11 truth were able, after years and years of effort to sue whoever for a set of prints minus a few details for building 7. Rumor has it there's a major effort to analyze those prints underway now and write a report of the findings.
Baring any new evidence coming to light, fall pattern of the beams, analysis of each beams failure points, measurements of each beams deformity, stuff like that, I don't see how we can figure much out. Which is why I'm inclined to only go with the photographic evidence. Its pretty irrefutable.
I know you keep mentioning folding at the base, or buckling is another term I keep hearing, but there is no photographic evidence of such unique movements, let alone that type of failure globally. Building fell straight down is what I see without any obvious deviation of the wall structure. My personal take is there's just no explaining it with what little information there is available. We are left with, "what are the odds"? I think we know what each others answer to that one is.
Anyway I don't think there's really enough data available, and seemingly deliberately so, to really say what exactly happened.
