FAA Grounds All US Flights Until Further Notice
Wired reports the FAA grounded all US flights on Friday afternoon, citing "extraordinary circumstances and for reasons of safety," with planes already airborne allowed to land but no new departures permitted. Nationwide ground stops are rare — last ordered on September 11, 2001 and in January 2023 after a NOTAM outage — and Transportation Secretary Sean Duffy said on X the stop stems from a communication issue at Air Traffic Control Centers that technicians are investigating.
