Can I throw this paper into the discussion please. Prof Kuttler was surprised to discover that even though he made every possible concession to enable a rapid fall rate, all his calculations came to a far longer time than that recorded. He even modelled all the floors 'floating' without any column support, or resistance, and it still worked out beyond the time seen by some margin. When he then introduced loss of energy used to reduce the concrete to dust, the fall time went well beyond even the most optimistic fall times admitted by various official estimates.
