FAA Lifts Nationwide Ground Stop After Telecom Outage, Flights Still Delayed
The Federal Aviation Administration lifted the nationwide ground stop on 13 November, ending a four-hour halt to all U.S. departures; officials said thousands of flights remained cancelled or delayed on 14 November. The agency said an overload of outdated radar equipment caused the telecommunications outage and found no evidence of a cyberattack.
The stop was initially imposed after a temporary telecommunications failure disrupted radar and radio communications at air traffic control centers, prompting the FAA to order all flights to remain on the ground—the first nationwide shutdown since 2001. FAA officials also examined whether the newly deployed SMART AI system had contributed to the outage.
