US Air Travel Resumes Slowly Following Major Legacy Tech Outage
Commercial flights across the United States were resuming on Saturday following a rare nationwide ground stop caused by a major telecommunications outage, though transportation officials warned that returning to normal operations would take time. The four-hour ground stop on Friday left hundreds of thousands of passengers stranded and triggered widespread disruption across major transport hubs.
Thousands of Flight Cancellations Compound Historic Airspace Paralysis
The incident marked only the second time such an alert had been issued in United States airspace since the September 11 attacks, aside from a localized notification system failure in January 2023. The ground stop was lifted at 8:15 pm Eastern Time on Friday after US Federal Aviation Administration officials restored full functionality to air traffic control facilities.
Secretary of Transportation Sean Duffy blamed the failure on aging infrastructure, pointing to overloaded 1980s copper lines, old switches, and legacy routers. Homeland Security Secretary Markwayne Mullin confirmed there was no evidence of foul play or hostile action behind the system failure.
The disruption cascaded across domestic and international networks. Tracking data from FlightAware showed nearly 6,000 flights canceled on Friday, including multiple international routes, while more than 3,500 US flights were already canceled by Saturday. Major hubs including New York’s JFK airport and Washington’s Reagan National Airport recorded widespread delays and long queues as travelers attempted to re-book.
Tim Johnson, consumer director at the UK Civil Aviation Authority, noted that ongoing follow-on disruptions would likely persist as commercial carriers worked to clear the backlog and reposition aircraft. In the wake of the outage, Secretary Duffy renewed an urgent appeal to Congress for $30.1 billion to fund the complete upgrade and modernization of the national air traffic control system.
