US aviation authority lifts nationwide flight ground stop after major telecom failure

UPDATE - follow-up to U.S. FAA ground stop LIVE updates: All flights grounded; no indication country under threat, says Homeland Security chief: The Federal Aviation Administration has cancelled its nationwide halt on airplane take-offs. The earlier order had grounded thousands of flights and stranded hundreds of thousands of passengers across the United States due to a major communications outage.

What Happened

Government officials confirmed the disruption stemmed from a temporary telecommunications outage impacting all Air Route Traffic Control Centres rather than any nefarious attack. Homeland Security Secretary Markwayne Mullin stated there was no sign of a threat to the country, emphasizing that the incident was not another 9/11. The emergency order marked only the second time such a nationwide alert was issued in U.S. airspace since the 9/11 attacks.

Impact

The sudden grounding caused widespread confusion and long lines at airports from New York to Las Vegas as travelers faced sudden delays and uncertainty. Some passengers were pulled off planes moments before departure by airline staff, while others rushed to rental car counters for alternative travel. Among those affected was 61-year-old traveler Janice Llewellyn, who feared missing her daughter's wedding in Toronto. Microsoft separately clarified on social media that the ground stop was not related to any of its services.

Context

This disruption occurred just a day after U.S. Transportation Secretary Sean Duffy asked Congress for $30 billion to modernise the country's air traffic control system. Air traffic control networks rely heavily on complex telecommunication systems to safely manage thousands of daily flights across national airspace. Major technical outages in these systems require immediate safety pauses to prevent any risk to aircraft in flight.
