Air travel across the United States came to a sudden halt Friday afternoon. The Federal Aviation Administration ordered an extremely rare nationwide ground stop at every U.S. airport on Nov. 13, 2026, "due to extraordinary circumstances and for reasons of safety." The cause, according to the FAA and Transportation Secretary Sean Duffy, was a communication problem hitting the air traffic control centers that guide planes across the country.
As of 2:45 p.m. Arizona time (MST), Friday, Nov. 13. This is a developing story, and we'll update it as the FAA shares more.
Departures frozen coast to coast
An advisory from the FAA's Air Traffic Control System Command Center put the ground stop into effect at 2:54 p.m. Central time, which is 1:54 p.m. Arizona time. Its message was blunt: "All departing traffic should remain ground stopped until further notice." Planes already in the air were allowed to keep flying and land. The FAA said inbound international flights would be "managed on a case by case basis."
Flight tracker Flightradar24 broke the news to millions of followers within minutes:
Issued by the FAA just moments ago, ALL US airports are currently ground stopped. This means NO flights may depart for US airports. Flights already in the air will be allowed to land. This is related to an FAA equipment outage. https://t.co/wgyuOXeF0k

That post has been viewed more than 1.1 million times. A few minutes later, Flightradar24 said about 3,100 aircraft were in the air headed for U.S. airports, and that "no additional aircraft are taking off at this time."
What went wrong?
Secretary Duffy confirmed the stop on X and pointed to a communications failure at the centers that manage high-altitude traffic between airports:
The @FAAnews issued a nationwide ground stop for all U.S. airports following a communication issue impacting all Air Route Traffic Control Centers. FAA technicians are investigating the issue. We will provide immediate updates as we have them.

The FAA's own statement was a little narrower. It said the problem hit "multiple" Air Route Traffic Control Centers, while Duffy said "all" of them. Charlotte Douglas International Airport told WBTV the stop was tied to "an FAA equipment outage." American Airlines told customers on X that the FAA was "working to resolve a technical issue affecting telecommunications at many air traffic control facilities across the country."
What actually failed, and why, has not been explained. Some accounts on X have speculated about a cyberattack, but no official has said anything to support that. For now, treat any claim about the root cause as unconfirmed.
The Associated Press summed up the situation for its 16 million followers:

Only the second time since 9/11
Nationwide ground stops almost never happen. The last one came on Jan. 11, 2023, when the FAA's NOTAM pilot-alert system failed. Departures were paused for about 90 minutes, and the ripple effects caused more than 10,000 delays and over 1,300 cancellations. Before that, the whole U.S. airspace was cleared after the Sept. 11, 2001, attacks.
Where things stand now
The FAA advisory listed an estimated end time of 10 p.m. Central (9 p.m. Arizona time), but it also said "until further notice," and the FAA has not said when flights will resume. As of 2:45 p.m. Arizona time, the FAA had not publicly announced that the stop was lifted. However, the FAA's live airport status feed, last updated at 2:41 p.m. Arizona time, no longer showed a separate nationwide ground stop. Instead, it showed departure delays at major airports, which may mean departures are starting to restart. That has not been officially confirmed.
The feed showed departure delays of up to 1 hour and 45 minutes at Chicago O'Hare and Teterboro. It also showed delays of up to an hour at Phoenix Sky Harbor, Newark and Miami. On the ground, a passenger at LAX told CBS News that newly landed planes couldn't get to their gates because departing jets were stuck in place.
If you're flying tonight, check your airline's app before heading to the airport, and expect delays and cancellations to keep rippling through the evening even after departures resume.
