Pls remember how Bazant defines a gravity-driven progressive collapse of a tower in his latest paper:
"The gravity-driven progressive collapse of a tower consists of two phases—the crush-down, followed by crush-up (Fig. 2 bottom), each of which is governed by a different differential equation (Bazant and Verdure 2007, pp. 312-313). During the crush-down, the falling upper part of tower (C in Fig. 2 bottom), having a compacted layer of debris at its bottom (zone B), is crushing the lower part (zone A) with negligible damage to itself. During the crush-up, the moving upper part C of tower is being crushed at bottom by the compacted debris B resting on the ground."

"When the upper floor (of zone C) crashes into the lower one (zone A), with a layer of rubble between them (zone C), the initial height h of the story (zone A below) is reduced to lambda h, with lambda denoting the compaction ratio (in finite-strain theory, lambda is called the stretch). After that, the load can increase without bounds."
...
"Since the initial crush-up phase terminates at very small axial deformation, it must be concluded that the simplifying hypothesis of one-way crushing is perfectly justified and causes only an imperceptible difference in results".
Now - this is the THEORY of NWO. If it works in THE REAL WORLD is another matter. Maybe Mackey can produce a new, real structure in the Hardfire show that shows us a gravity driven collapse of a tower?
