Why did the FAA issue a nationwide ground stop? What we know

The Federal Aviation Administration halted departures nationwide Friday after a telecommunications outage affected air traffic control centers. The ground stop disrupted flights at airports across the country, including Dallas-Fort Worth International Airport and Dallas Love Field. Officials said they had no timeline for restarting departures, while airlines warned of delays lasting through the day. Flights already in the air were accounted for, and international arrivals were handled case by case.
