Original Note:
According to NIST, the collapse was initiated by fires ignited by debris from the collapse of the nearby North Tower. The fires caused thermal expansion in floor beams, leading to the failure of a critical column (Column 79), which triggered a progressive collapse. https://www.nist.gov/world-trade-center-investigation/study-faqs/wtc-7-investigation https://www.govinfo.gov/content/pkg/GOVPUB-C13-4d4c17460292ee57ef313f6491fa8d1e/pdf/GOVPUB-C13-4d4c17460292ee57ef313f6491fa8d1e.pdf https://www.nist.gov/publications/final-report-collapse-world-trade-center-building-7-federal-building-and-fire-safety-0 https://www.commerce.gov/news/blog/2021/08/20-years-later-nists-world-trade-center-investigation-and-its-legacy
