FAA issues US national ground stop on all flights

"All ​departing traffic should remain groundstopped until further notice," the US Federal Aviation Administration said. US Transportation Secretary Sean Duffy said technicians are investigating the issue. The US Federal Aviation Administration (FAA) on Friday issued a ground stop on all national flights .

The FAA is the US government agency responsible for air traffic control. In a post on X, US Secretary of Transportation Sean Duffy said the stop was due to a communication issue impacting all Air Route Traffic Control Centers. It's the first nationwide ground stop since January 2023, when the FAA dealt with a system outage.

Prior to that, the last ground stop was after the September 11, 2001 terror attacks .
