WTC 7, Free-Fall Claims, and the NIST NCSTAR 1-9 Critique Spine
NIST NCSTAR 1-9 and 1A conclude fire-induced progressive collapse of WTC 7; NIST FAQs acknowledge roughly 2.25 seconds of free-fall acceleration during the visible descent. Adherent critique treats that stage as demolition evidence. The Archive documents NIST reports and the freefall claim-set side-by-side under contested/L2 without baptizing controlled demolition or dismissing the measurement.
