Flights halted at airports across US due to air traffic control communications problems

The Federal Aviation Administration grounded all flights nationwide Friday afternoon because of communications problems at regional air traffic control centers.The FAA notice said the ground stop was being imposed “due to extraordinary circumstances and for reasons of safety.”Transportation Secretary Sean Duffy said there is a communications issue affecting the 22 regional air traffic control centers that direct planes en route between airports nationwide. He said FAA technicians are investigating. This is the first nationwide ground stop since January 2023, when a key FAA computer system malfunctioned. Before that the last time had been after the Sept. 11, 2001, attacks.Secretary of Homeland Security Markwayne Mullin said there was no indication yet that "this was a nefarious attack against us. It's just a telecommunications outage."“Everybody's safe. There's no reason to be concerned about your loved ones if they're flying,” Mullin said.There is no timeline for restarting flights. Mu
