FAA ground stop halts all US departures until further notice

The Federal Aviation Administration grounded all departing flights in the United States on Friday afternoon, citing “extraordinary circumstances” and safety concerns.

Flights will remain grounded until further notice, according to an FAA advisory. Inbound international flights will be handled case by case.

The FAA did not immediately say what caused the ground stop. The order followed radio frequency and radar outages at several air traffic control centers.

Earlier Friday, the agency had stopped departures at Chicago’s O’Hare and Midway international airports because of an equipment outage.

Before the nationwide order, the FAA reported equipment-related departure delays at Phoenix Sky Harbor International Airport and other major airports.

This is a developing story.
