>but they weren't there after the collapse
yes they were
on their own and with the massive pile of rubble damaging them on the way down before crushing them in from the sides as the rubble hits the ground at high speed
needless to say they didn't last long
you can see the cores still standing in both WTC 1 and 2 for some seconds after the main collapse finishes, before they also start to fall
