FAA lifts nationwide ground stop after communications outage, flights still delayed
The Federal Aviation Administration lifted the nationwide ground stop that had halted all U.S. flights after radar, communications and transponder problems, saying officials found no evidence of a malicious attack. The stop had been imposed on November 13 when a temporary telecommunications outage disrupted air-traffic-control communications at centers nationwide, prompting the FAA to order all departures to remain on the ground. The shutdown affected major New York area airports, leaving tens of thousands of passengers stranded and marking the first all-U.S. grounding since the 2001 attacks.
