Original Note:
WTC-7 wasn't blown up, that's an easily debunked conspiracy theory. In fact, the 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
