A three story collapse at one time would have been impossible. The columns are supported by beams at every floor.
Each floor was capable of supporting a significant number of additional floors (much more than one or two. NIST even acknowledged this in one of their FAQs. There would be no chance of developing a dynamic load to equal that static load when just one floor falls onto the one below. ROOSD cannot work right away in the early stages of the collapse. It needs a significant number of floor to have been broken loose.

Quote:And no I don't think the tower would stand with one floor of columns instantly vaporized. And yes a floor can support one or two as additional floors slabs as static load...dynamic... not so sure.Well you need to explain how the column energy absorption can be by-passed. So far all I have seen you and like minded individuals who don't accept demolition as the cause for collapse do is a hand wave that they missed each other. You have no load or mechanism to cause that condition.
