I thought the “largest elevator upgrade in history” was WTCs 1 and 2, not 7, but do check if you wish.

Explosives in WTCs 1 and 2’s cores do not help us explain those collapses, because the video record shows that those cores fell only after the floor stacks had torn themselves to pieces and the perimeters had toppled outwards.
