Attributed to Dean Riviere in NIST volume 1-6. Watch at wtcdata.nist.gov here (you must click Continue to agree to terms before the link will work). The clip appeared in: 1. “Why the Towers Fell” by PBS-NOVA, 2002 (which says architects filmed it) and 2. U.S. vs. Moussaoui trial exhibit P200015.
Probably the best shot of the South Tower core before it crumbled. Other shots of the steel-frame core are listed under the WPIX Metrocam shot above. Bonus photos: hereisnewyork.org 5712 and 5711.
Raw NIST FOIA file: NOT in the Cumulus release 14, aside from the Discovery documentary clip “How Towers Fell 14.”. It should have been in the SkidmoreOwingsMerrill folder, which at least gives us the information of location: 14 Wall Street. Also, the release 14 Skidmore 1 clip matches the 9:37:04 explosion as seen in WNYW Dub1 35 and CNN Dub17 12. For the collapse footage see 911datasets.org release 27, 42A0272 – G26D148 at YouTube link 1 above.
