The Pentagon was not struck by AA77 (missile or other object)
Labelled conspiracy in official and most aviation sources. Ingested because the instruction is not to hide labelled claims. NTSB path, ASCE damage, and passenger DNA are the principal contradicts.
Likelihood — more or less than 50%
14%
Less than 50% — strongly contradicted by the sources
Start at 50%. Move by half of the net source score after uncertainty. Net source score is -0.81 (from −1 contradict to +1 support). Uncertainty is 10%. So 50% + 50% × -0.81 × 90% remaining certainty = 14%.
0.5 + 0.5 × -0.81 × (1 − 0.10) = 0.135
