We don't see those walls, MHG. When we get to the levels where what I describe is happening, everything is behind a huge cloud of debris, dust, and smoke. Anyone who claims anything counter to that is not telling the truth or has Superman's X-Ray vision. Very few of the curtain wall panels were recovered. That curtain wall was STRUCTURAL, it's not there merely for decorative purposes. You hit that a plasma at 2700 PSI and at what ever temperature it reached, there is not much going to be left of it. It's the primary egress point for all that superheated air/plasma. Those panels have to start falling from a zero velocity starting point and they are surrounded by very hot materials.
Sorry, casn’t buy that based upon the video evidence. If your explanation makes you happy, enjoy.
