Advertisment:Claim: The FAA flight stoppage of Jan. 11, 2023, was the first time the agency grounded all U.S. flights since the terrorist attacks of Sept. 11, 2001. Rating: About this rating TrueOn Jan. 11, 2023, Fox News published the headline, "FAA orders all flights grounded for the first time since 9/11." Hours earlier, the U.S. Federal Aviation Administration (FAA) had ordered that all U.S flights be grounded due to what was referred to a computer system outage. Beyond these two reports, we were not yet able to find any other dates between 9/11 and January 2023 when any such grounding order had been given by the FAA on a nationwide scale. The system used to be telephone-based, with pilots calling dedicated flight service stations for the information, but has moved online.
