FAA Grounds Every Flight in America: Rare Nationwide Ground Stop Freezes US Skies for Hours After Air Traffic Communications Collapse
Thousands of flights cancelled as all 22 regional air traffic control centres lose communications. This is the first nationwide ground stop since 2023.
Washington, The Gulf Observer: America’s skies came to a sudden standstill on Friday when the Federal Aviation Administration (FAA) issued a rare nationwide ground stop. Every departing domestic flight was held on the ground after a communications failure hit the country’s air traffic control network.
The FAA ground stop was imposed on Friday afternoon, 13 November, “due to extraordinary circumstances and for reasons of safety.” All aircraft operators were told that departing traffic must stay grounded until further notice, while inbound international flights were handled case by case.
What Caused the FAA Ground Stop
US Transportation Secretary Sean Duffy said the shutdown followed a communications issue affecting all 22 Air Route Traffic Control Centers, the regional facilities that guide aircraft while they are en route between airports. FAA technicians were sent to investigate.
Duffy described it as a telecommunications outage and said every flight was accounted for and that planes already in the air would be able to land safely. Media reports, citing sources, said an update to the network connecting the air traffic control system may have triggered a reboot, a crash and the outage that followed.
The White House said there was no indication of any “nefarious act.” A senior White House official said President Donald Trump was receiving constant updates as the crisis unfolded.
More Than 3,000 Planes in the Air
When the order came, flight tracking data showed more than 3,000 aircraft in the air over the United States or heading towards it. The decision affected airports from coast to coast. Los Angeles International Airport (LAX) and other Southern California airports stopped all departures for several hours, and Boston Logan confirmed that all departures there were caught by the order.
At Chicago, an FAA advisory described an equipment outage affecting departures from every air traffic control zone in the country. Passengers at Midway, O’Hare and other major hubs were stranded at gates as departure boards filled with delays and cancellations.
Ground Stop Lifted After More Than Five Hours
The FAA lifted the nationwide ground stop more than five hours after the first public alert, allowing domestic flights to depart again. The damage was already done: thousands of flights had been cancelled, and airlines warned that delays and cancellations would continue as aircraft and crews return to position.
Delta Air Lines said it was safely resuming operations after the FAA-mandated stop was lifted, and other carriers moved to rebuild their schedules through the night.
Only the Third Nationwide Ground Stop Since 9/11
This is the first nationwide ground stop since January 2023, when a key FAA computer system failed. Before that, the only such order came after the 11 September 2001 attacks, which shows how rare Friday’s shutdown was.
Thanksgiving Travel Fears and the Modernisation Debate
The outage came less than two weeks before the busy Thanksgiving travel period. Duffy said he expects flights to be fully operational by the time holiday travel peaks.
The incident is likely to strengthen calls to overhaul America’s ageing air traffic control system. Congress approved $12.5 billion last year to upgrade the technology, and Duffy has said a further $30 billion is needed. The White House has begun lobbying lawmakers to approve the money.
For millions of travellers, Friday’s FAA ground stop showed how quickly one communications failure can shut down the world’s busiest aviation network.
