FAA ground stop lifted after telecom outage; Duffy seeks $50B overhaul

"We had intermittent communication and intermittent radar … which is why we shut the airspace down,"

Homeland Security Secretary Markwayne Mullin characterized the event as a "telecommunications outage" and said there was no indication of a cyberattack. "This is not another 9/11," Mullin told reporters. "We were wanting to assure all the American people this isn't a safety risk to the American people or another 9/11." The outage came three days after the FAA completed a nationwide rollout of its new AI-powered Strategic Management of Airspace, Routes and Trajectories (SMART) system to all 22 air route traffic control centers on November 10. The $875 million, 12-year contract with Air Space Intelligence (ASI) had been operating in Washington, D.C. Airspace since September 21, where the FAA said it helped reroute 180 flights. The timing prompted immediate scrutiny. More than two dozen lawmakers had written to Duffy and FAA Administrator Bryan Bedford in October urging a pause in the deployment until questions about safety evaluations, personnel training, and oversight were answered. The National Air Traffic Controllers Association said it was not consulted on SMART's design or testing.

"You can't rule out anything at this point. We are going through that process and we're going to find out what happened. When we do, we'll take the appropriate actions to make sure it doesn't happen again."

ASI denied any connection within minutes of the ground stop. "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," the company posted on X. The FAA has stressed that SMART is a decision-support tool that generates advisory routing recommendations reviewed by specialists in Washington before reaching local controllers, who decide whether to accept them. It does not carry communications or radar functions. Technical analysts noted the reported failure mode — radio frequency communications and radar — operates on a different layer than SMART's planning software. "Frequency and radar are the voice and surveillance layer: the radio links and scope data that let a controller separate aircraft. Those are hardware and telecommunications, not planning software," Techaeris reported. Still, former DOT Inspector General Mary Schiavo called the timing "too much coincidence" on CNN, while acknowledging she did not know if the events were linked. Mullin later suggested the outage may have stemmed from integrating new technology with legacy systems: "as secretary Duffy and FAA was going in and putting patches into the system, they were putting new equipment and new technology and that new equipment, new technology just wasn't, it was overwhelming the older system."

The ground stop stranded more than a million passengers. At LaGuardia Airport, Fox News reported more than 260 cancellations and 600 delays. One Frontier Airlines passenger told reporters she would sleep at the airport; two Canadian travelers had their Toronto flight rebooked for Tuesday, with one noting he lacked his insulin medication. "That just gives you an idea of just already the domino effect we're seeing as these delays and these cancellations start stacking up," Fox correspondent Bryan Llenas said. Delta Air Lines warned that returning to normal operations would take time as it repositioned aircraft and crews. American Airlines, JetBlue, and Frontier issued travel waivers for passengers scheduled to fly through November 15. Amtrak reported higher-than-normal call volumes from travelers seeking alternatives. Enterprise Rent-A-Car said it was seeing "higher-than-usual demand." The Senate Commerce Committee, led by Chairman Ted Cruz, said the incident "highlights the need to prioritize modernizing ARTCCs over other projects. No new ARTCC has been built since LBJ was in office." Cruz noted he had secured $1.9 billion in the Working Families Tax Cut Act to replace and consolidate outdated centers. Duffy framed the outage as validation for a complete rebuild. "The president for the last year has been asking Congress to fully fund a full build of a brand new air traffic control system," he said. "I want Congress to give us emergency funding. I want $50bn. President Trump is a builder. He is going to build this network, and deliver for the American people." Congress approved $12.5 billion last year for modernization, replacing copper wiring with fiber, phasing out old radio systems, and installing new computational platforms. Duffy has said another $30 billion is needed to complete the work, with a target of December 2028. The 2023 NOTAM outage, which grounded flights for hours, was traced to a single corrupted database file that propagated into the backup system. Friday's failure, whatever its cause, again exposed the structural risk of upgrading a live, mission-critical system while it manages thousands of flights. What to watch next

• FAA technical forensics on the telecommunications failure, no timeline announced
• Congressional response to the $50 billion emergency funding request
• Whether lawmakers revive demands to pause SMART pending investigation results
• Airline recovery operations through the weekend, crews nearing duty limits, aircraft out of position
• Travel waiver terms for passengers with flights through November 15

Microsoft, which experienced its own global outage affecting Outlook and Teams on Thursday, said it had "no indication that the FAA's nationwide ground stop is related to any Microsoft services." The National Weather Service also clarified that its radars were operating normally despite circulating claims otherwise.
