HuffPost reports that the FAA lifted a nationwide ground stoppage on 13 November 2026 more than four hours after halting all U.S. flights over a communication issue it attributed to overloaded, outdated systems, with FlightAware logging more than 10,000 delayed flights and the cause still unclear. Secretaries Sean Duffy and Markwayne Mullin said at a press conference that a cyberattack did not appear to be involved, while Duffy blamed Congress for unfunded modernization and said the country's 'old, old switches' had failed everywhere.
