Chandler, Walter, Szamboti — Instantaneous free fall of WTC 7 and NIST's attempt to hide it (Jun 2023)

Journal of 9/11 Studies · 2023-06-01

Using multi-point tracking, Chandler/Walter/Szamboti report that after ~1.4 s of near-immobility of most of the north and west rooflines, those rooflines entered free fall together within ~0.2 s at ~8.0–8.2 s after east-penthouse collapse, ~9.8 m/s² for ~2.5 s.
