Do you have such an idea what explosive tech was available on 9/11? Can you source that idea and provide evidence?
Yes, I am saying that a "gravity collapse" ejected multi-ton beams into near-by buildings. Hint: Explosive controlled demolitions are gravity collapses, too. >90% of the energy expended in a CD to destroy the building comes from gravity. If you claim gravity was not enough to do those ejections, you need to explain how else so much kinetic energy got into the multi-ton beams. Oh, and who would be so foolish as to put such an excess of explosives to the beams and make them behave so suspiciously.
Also, you AGAIn dodged my several questions about expected and observed debris volume, evidence for no basement collapse, and if you think the towers didn't collapse. Why?
