WTC 7 was 'pulled' — a controlled demolition was ordered that afternoon
Silverstein 'pull it' plus free-fall plus no aircraft impact. Distinct from H006 (energetics contributed) in that H018 asserts an order to demolish.
Likelihood — more or less than 50%
57%
More than 50% — weakly supported by the sources
Start at 50%. Move by half of the net source score after uncertainty. Net source score is 0.15 (from −1 contradict to +1 support). Uncertainty is 12%. So 50% + 50% × 0.15 × 88% remaining certainty = 57%.
0.5 + 0.5 × 0.15 × (1 − 0.12) = 0.566

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.
