The Federal Aviation Administration grounded all US flights Friday afternoon, due to “extraordinary circumstances and for reasons of safety,” the agency said in a statement. Flights already in the air will be allowed to land, the agency said, but no new ones are permitted to take off.
In a post on X, US Transportation Secretary Sean Duffy said that the ground stop was related to a communication issue affecting Air Traffic Control Centers.
The ground stop came after widespread reports of radio frequency outages among several of the nation’s most critical Air Traffic Control Centers, including in Boston, Chicago, and New York.
