I've no doubt that the fuel fires were enough to collapse the towers. Hot steel buckles and 20+ stories of pile driver does the rest. Thats why the 2nd building hit collapsed 1st, more mass above the buckling point. Of course the building 7 controlled demo shows the whole thing was a deep state operation. Bin laden CIA links were well known. Hard to know if pentagon was hit by plane. Logically you would attack from above, not aim the plane at the side.
