Mr. Lewis,
All three collapses were gravity driven but NOT gravity started. CDs destroy the columns in the bottom of a structure so the weight (gravity) pulls the mass above down and it crashes and crumbles. I realize many refuse to accept this explanation for this part of the collapses.
It appears from the observations of Bldg 7 that the core failed first and not completely but the failure seems to have been perhaps as low as floor 7 or as high as floor 13. The failure progressed westward through the core and the first notice that something was seriously wrong to the naked eye was the collapse of the East Penthouse which literally plunged right down through the entire building... There was movement before the collapse of the East penthouse which can only be detected with computer analysis of the videos. This motion seems to indicate that there WAS load redistribution going on and the structure was torquing and twisting... distorting. We don't know what caused this distortion. It doesn't seem the result of a bomb blast.... but cutting of some columns and main girders... perhaps.
When the entire core had dropped it pulled the OOS floors down and then the skin descended like a hollow box and it may have slipped outside the skin beneath it. I haven't studied Bldg 7 much. It doesn't appear to be a ROOSD though.
