On September 11, 2001 three buildings collapsed. Two of those were hit by large airplanes supposedly flown by terrorists. We focus here on the third building "collapse" which has become controversial since it fell at free fall acceleration in part of its descent.
Here we collect most of the known footage. 25 angles. Few with audio. WTC 7 data collection.

The analysis of structural steel from WTC 7 was limited to the journal JOM in “An Initial Microstructural Analysis of A36 Steel from WTC Building 7” (mirror) and Appendix C of the FEMA WTC Building Performance Study. Add to that a University of California at Berkeley professor who traveled to New York and measured steel beams, Dr. Abolhassan Astaneh-Asl.
