America’s skies went silent Friday afternoon. At 3:54 PM ET, the FAA ordered every single departing flight in the United States to stay on the ground — a nationwide ground stop triggered by a telecommunications outage that knocked out communications at every Air Route Traffic Control Center in the country.
It is only the second nationwide ground stop since 9/11 — the other was the January 2023 NOTAM system outage — and it left thousands of travelers stranded in terminals from Atlanta to Los Angeles, scrambling for rental cars, trains and buses.
Transportation Secretary Sean Duffy told reporters at the White House that controllers began spotting instability in the radar and communications systems at 3:36 PM ET. “What we have is an incredibly old air traffic control system,” Duffy said, explaining that switches and routers in the FAA’s aging analog technology got overloaded and began feeding inconsistent data — so the agency shut departures down for safety. Homeland Security Secretary Markwayne Mullin called it a “telecommunication outage throughout FAA” and stressed there was no reason for the public to be afraid and no indication of a cyberattack or anything nefarious.

The damage, by the numbers: according to the Wall Street Journal, citing FlightAware data, more than 14,500 flights were upended — close to 6,000 canceled on Friday and nearly 1,000 more already canceled for Saturday, with over 10,000 flights delayed. By early evening, cancellations were already topping 3,000 nationwide, hitting Chicago O’Hare, LaGuardia, Dallas-Fort Worth, JFK and Boston Logan the hardest.
And yes — Atlanta felt it. Hartsfield-Jackson, the busiest airport on the planet, was snarled right along with every other major hub in America. Flights already in the air were allowed to land, and some international departures were handled case by case, but for hours, nothing new left the ground anywhere in the country.

The FAA announced the ground stop was cancelled on its website around 8:30 PM ET — more than four hours after it began. But Friday’s flying day was effectively over, and the recovery will ripple for days: planes and crews are out of position, and some crews have timed out. Aviation experts told USA Today that airlines are now focused on resetting for the weekend — and that if you’re rebooking, the earliest flight of the day and nonstops are your best bets.
The outage is already a political firestorm: Mullin said President Trump has declared the air traffic control failures a “national emergency,” and Duffy renewed the call for Congress to fund a full rebuild of the system — raising the ask from $30 billion to $50 billion. “The president’s asked for $30 billion,” Duffy said. “I want $50 billion.”
Flying this weekend? Read this: check your flight with your airline BEFORE you leave for the airport, get there early, and know your rights — if your flight is canceled and you choose not to be rebooked, federal rules entitle you to a refund.
