On November 14, the United States Federal Aviation Administration announced a nationwide ban on all aircraft departures. The ban was cited as a response to an extraordinary telecommunications system failure affecting all air traffic control centers, which grounded flights nationwide.
Transportation Secretary Sean Duffy and Homeland Security Secretary Markey Mallin briefed the press, stating that the FAA had introduced a nationwide ban on departures at all US airports due to communication problems affecting all air traffic control centers. About 3,100 planes were approaching U.S. airports at the time, each requiring individual decisions on in-flight operations. Despite the disruption, officials assured the public that safe landings would be ensured for all passengers and crew.
The root cause of the outage, according to the FAA, was a telecommunications system failure. This unexpected event brought air travel to a standstill, with no takeoffs permitted at any of the country's airports. The FAA cited safety considerations in making this decision.

On November 13, Microsoft experienced a global service outage affecting Outlook, Teams, Copilot and Microsoft 365. While the tech giant worked to resolve the issue, officials were quick to dismiss any link between the Microsoft outage and the nationwide flight disruptions. “There are no objective grounds for linking the two events; each requires separate analysis and resolution,” Markeyne Mallin, the Homeland Security Secretary, stated.
Markwayne Mullin stated, “This is not a repeat of 9/11, this is a telecom failure.” As Markey Mallin assured the public, “At the moment there are no signs that this was any malicious act. So far it is exclusively a telecommunications system failure.”
