“No one’s hands are clean here,” wrote Ari Emanuel on X on November 13, 2026, pointing blame at the previous administration as a nationwide ground stop halted American air travel.
The Federal Aviation Administration ordered the emergency grounding due to extraordinary safety circumstances, Deadline reported. The stoppage grounded more than 3,500 flights across the country before the airspace reopened later that evening.
The current ground stop is not based on or a result of the SMART system, any product of ASI or our integration with FAA and ATC.
Transportation Secretary Sean Duffy pointed to a data overload on routers as the root cause of the crisis, according to statements at a White House briefing covered by The Hill. Duffy said that the switches and routers became overloaded with data, causing inconsistencies that forced officials to shut the domestic system down.
The disruption unfolded as the agency implements new technologies and workforce adjustments. The FAA recently rolled out an artificial intelligence tool called the Strategic Management of Airspace, Routing and Trajectories, known as SMART, to assist with air traffic management.
No one’s hands are clean here. However, Mr. Secretary Buttigieg, you had four years in the job and infrastructure money, yet made zero progress modernizing the FAA. You left a failing system in place. THANKS!
Data Overload Triggers Ground Stop
The nationwide grounding began on a Friday afternoon and lasted for roughly four hours, affecting thousands of travelers. Duffy explained during the White House briefing that the disruption originated from technical communication issues across Air Route Traffic Control Centers.
Air Space Intelligence, the company behind the newly deployed FAA AI tool, quickly distanced its software from the outage. The firm stated on X that the ground stop was not based on or a result of the SMART system or any product integration with the FAA.
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.
Duffy backed up that assessment during his briefing. He asserted that the $875 million system was completely disconnected and not plugged into the core network functions that failed, eliminating any possibility that the software caused the routers to crash.
The technical failure renews intense scrutiny over the aging infrastructure of American aviation. Duffy and Homeland Security Secretary Markwayne Mullin called on Congress to approve substantial funding to rebuild the control network, with Duffy seeking $50 billion for a complete overhaul.

Political Clash Over FAA Modernization
The crisis prompted sharp political sparring over who bears responsibility for the state of the nation’s air traffic network. WME and TKO executive Ari Emanuel criticized former Secretary of Transportation Pete Buttigieg on X, accusing him of making zero progress modernizing the FAA during his four years in office despite having infrastructure funding available.
“[Mr. Secretary Buttigieg,] you had four years in the job and infrastructure money, yet made zero progress modernizing the FAA. You left a failing system in place. THANKS!” wrote Emanuel, according to Deadline.
The debate over modernization coincides with significant changes to staffing and operational tools within the agency. “modern staffing models and scheduling tools.” the FAA cited when it reduced its active controller staffing target from 14,633 down to 12,563, according to the article.
Labor representatives have expressed concerns regarding the trajectory of these changes. The union representing air traffic controllers stated it was not involved in designing or testing the SMART system, even as the agency expands the AI tool across all 22 air traffic centers nationwide.
Today’s nationwide ground stop happened because our air traffic control system is operating on DECADES-OLD, analog equipment that simply cannot compete with the demands of the 21st century.⁰@FAANews is modernizing this aging infrastructure thanks to a $12.5 billion down… pic.twitter.com/nXUPHkdNdV
Reasons for the FAA ground stop and flight impact
What caused the FAA ground stop?
Transportation Secretary Sean Duffy said that routers across Air Route Traffic Control Centers became overloaded with data, generating inconsistencies that required officials to shut down domestic airspace.
Did the new AI air traffic tool cause the outage?
No. Air Space Intelligence and Transportation Secretary Sean Duffy both confirmed that the SMART system was completely disconnected from the routing network and played no role in the failure.
The nationwide FAA ground stop has been lifted. Flight delays and cancellations continue. Check with your airline for the latest information.
How many flights were affected by the stoppage?
More than 3,500 flights were grounded before the FAA lifted the stop and reopened the airspace after a four-hour shutdown.
What is the SMART system designed to do?
The $875 million cloud-based system combines weather patterns, flight paths, and controller staffing metrics to make scheduling recommendations and identify optimal flight routes for air traffic controllers.
The FAA has temporarily paused departures nationwide. Flights already in the air can continue to their destinations. We expect disruption to our schedule for the rest of the day, depending on the length of the FAA’s nationwide ground stop. It will be all hands on deck across…
