Matching claims

  • partially_supportedCLM-003

    Omar al-Bayoumi was a paid cooptee of Saudi GIP reporting via Ambassador Bandar.

  • indeterminateCLM-008

    Bayoumi had advance knowledge that the 9/11 attacks would occur.

  • well_supportedCLM-009

    The FBI withheld Bayoumi-related intelligence from the 9/11 Commission.

  • disputedCLM-013

    Aircraft impact and the ensuing fires initiated the collapses of WTC 1 and WTC 2 without additional energetic devices.

  • disputedCLM-015

    WTC 7 collapsed from ordinary office fires following debris impact, without explosives.

  • indeterminateCLM-021

    Unusual pre-attack put-option activity reflected trading by people with advance knowledge of the plot.

  • unverifiedCLM-022

    The five Urban Moving Systems detainees had advance knowledge of the attacks as an Israeli intelligence team.

  • contradictedCLM-025

    Some of the named 19 hijackers were not aboard the aircraft / were still alive.

  • disputedCLM-030

    WTC 7's entire measurable north and west rooflines instantaneously transitioned to free fall, a behaviour NIST's Stage 1 description conceals.

    The 9/11 Commission was not a truth-seeking body; the Report is a 'Zelikow Report' defined by systematic omissions.

  • disputedCLM-033

    First-responder explosion-language about the Twin Towers is evidence of demolition charges.

  • unverifiedCLM-034

    Reported 9/11 aircraft manoeuvres were not flyable manually by the named hijacker-pilots (automation/remote guidance).

  • disputedCLM-036
