A software problem disrupted radio communications at both control towers at Dallas-Fort Worth International Airport early today.
That delayed flights up to an hour as one of the busiest air travel weeks of the year was just getting under way. Spokesman Roland Herwig of the Federal Aviation Administration says a card containing fresh software has been flown into DFW and is being installed, but residual delays continue.
The outage affected both incoming and outgoing flights. The FAA had declared a "ground stop,'' which cuts incoming flights by holding planes on the ground at their previous airport stop. At the worst point of the disruption, the FAA Web site said flight departures were delayed by up to an hour and 15 minutes.
