AA11 struck WTC1
Testable proposition: American Airlines Flight 11, a Boeing 767, struck World Trade Center 1 at 08:46:40 on 11 September 2001. Competing no-plane claims exist in labelled-CT literature and are stored against this proposition rather than deleted.
Likelihood — more or less than 50%
97%
More than 50% — well supported by the sources
Start at 50%. Move by half of the net source score after uncertainty. Net source score is 1.00 (from −1 contradict to +1 support). Uncertainty is 7%. So 50% + 50% × 1.00 × 93% remaining certainty = 97%.
0.5 + 0.5 × 1.00 × (1 − 0.07) = 0.965
