Original Note:
Debris from the collapse of WTC 1 ignited fires on at least 10 floors of WTC 7 at the western half of the south face. After 7 hours of uncontrolled fires, all 23 central columns, followed by the exterior columns, failed in what's known as a "progressive collapse". https://www.popularmechanics.com/technology/design/a3524/4278874/ https://www.youtube.com/watch?v=PK_iBYSqEsc https://www.nist.gov/publications/final-report-collapse-world-trade-center-building-7-federal-building-and-fire-safety-0
