Transportation Secretary Sean Duffy pointed squarely at obsolete hardware Friday night for the nationwide ground stop that froze U.S. air travel for more than four hours, and demanded Congress hand the Department of Transportation $50 billion in emergency funding to replace a system he said is running on borrowed time.
Speaking at a White House news conference, Duffy said the trouble began around 3:36 p.m. ET, when the Federal Aviation Administration began seeing inconsistency in radar data and communications reaching air traffic controllers. The agency issued a nationwide ground stop as a precaution, and the FAA lifted it at 8:15 p.m. ET, according to NBC News. More than 7,000 flights were canceled while airports filled with stranded passengers, NBC reported. The New York Times reported that hundreds of flights were diverted and internationally bound flights needed permission to depart while the order held.
Duffy did not soften his diagnosis. "We have old, old switches, old routers. We use 1980s little copper lines," he said. "What went down was old, right? It was the old legacy equipment. It failed."
He described an overloaded system rather than a lost one. According to NBC News, Duffy said the FAA did not lose all telecom or radar capabilities, but the instability — inconsistent data from radars and communication links with aircraft — forced the ground stop. "The TRACONS and the centers, we started to have inconsistency in the data from the radars and our communication with airplanes," he said. "FAA was able to handle it. We did it out of an abundance of caution."
Homeland Security Secretary Markwayne Mullin, appearing alongside Duffy, said there was never any indication a cyberattack triggered the failure — but did not close the door. "We are still looking, and we're not going to rule it out," Mullin said, per the Times. He said lives were never in danger.
Duffy's Demand: $50 Billion, and He Wants It Now
Duffy framed the funding request as an emergency, not a budget line item. "This is an emergency. I want Congress to give us emergency funding," he said. "This is bipartisan. This is American. I want $50 billion."
The administration has already secured $12.5 billion for modernization, Duffy said, describing it as a down payment. The Times reported that Duffy has spent months pressing for at least $30 billion more, and that the ground stop has now given him a fresh argument. Some work is underway: FLYING magazine reported more than 40 new switches have been installed, and federal officials say roughly half of the aging copper wiring used to transmit radar and communications data has been replaced with modern connections.
Duffy predicted schedules would be back to normal before the Thanksgiving travel rush, though the Times noted he cautioned recovery would take "some time" as crews and aircraft were left out of position.
Friday's shutdown is not the first warning sign. NBC News reported the FAA's analog-era equipment has produced several outages in recent years, including a May 2025 incident in which radar screens at Newark Liberty International Airport went black during a 90-second outage.
For travelers, the practical fallout is already counted in thousands of canceled flights and days of disruption. For Congress, the bill is now on the table: $50 billion, requested as emergency spending, attached to a failure that played out live on every airport board in America.
Our Take
This is what happens when Washington spends decades writing checks for everything except the basics. The FAA is moving America's air traffic through 1980s copper and routers older than many of the controllers using them — and it took a four-hour nationwide halt to get the conversation started. Duffy is right to call this an emergency, because it is one. The only question is whether the same Congress that happily rubber-stamped bloated packages for foreign adventures and green boondoggles will balk at $50 billion to keep planes moving safely over American soil. Patriots should be watching who votes no — and remembering it the next time a router fails and their flight home gets canceled.
