The FAA released an official advisory on Friday afternoon announcing a “national ground stop due to extraordinary circumstances and for reasons of safety,” halting all departures at every airport in the United States.
“By order of the Federal Aviation Command Center all airports are ground stopped,” the advisory states. “All departing traffic should remain ground stopped until further notice.” Inbound international flights will be managed on a case by case basis. The stop follows radio frequency and radar outages at several air traffic control centers.
