Original Note:
Debris set over ten floors alight within WTC7 which was directly across from where the North Tower fell. Heat from the uncontrolled fires caused steel floor beams and girders to thermally expand, leading to a chain of events that caused a key structural column to fail. https://www.nist.gov/world-trade-center-investigation/study-faqs/wtc-7-investigation https://fullfact.org/online/world-trade-center-7-9-11/ https://discovery.ucl.ac.uk/id/eprint/10146056/1/WTC7%20Revisited-uploaded.pdf
