Air traffic control communications failures forced a nationwide ground stop across United States airports.
Every domestic departure was halted indefinitely following a communication issue that impacted regional air route traffic control centers, nova.bg reported. Aircraft already airborne did not receive orders to land immediately, and international flights were handled on a case-by-case basis, nova.bg stated.
Federal Aviation Administration technicians investigated the root cause of the technical disruption. The agency issued a nationwide ground stop after the communication issue crippled Air Route Traffic Control Centers, Secretary Sean Duffy reported on X.
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.

Security Officials Rule Out Cyberattacks
Law enforcement and homeland security officials confirmed that preliminary findings showed no indication of a cyberattack, according to nova.bg.
There has been a temporary telecommunications outage – out of an abundance of caution all flights have been halted. Every flight has been accounted for and international flights will be handled on a case by case basis.
Department of Homeland Security Secretary Markwayne Mullin addressed reporters at the White House to reassure the public. Mullin said that telecommunications services suffered an outage rather than a hostile strike.
“Everybody is safe. There is no reason to be concerned about your loved ones or anything like that,” Mullin told journalists at the White House, according to Clash Report.

Mullin also assured the public that authorities accounted for every airborne machine.
Air Traffic Control Centers Slip Into ATC Zero
Selected regional airspace sectors transitioned into an “ATC Zero” operational status as communication links severed. This designation indicates that facilities can no longer provide air traffic control services, CNN reported.

Audio recordings captured air traffic controllers warning approaching pilots of crippled systems. A dispatcher alerted aircraft near Chicago to the sudden loss of equipment functionality.
“We’ve lost all radio frequencies and all automated handoff systems, as well as flight tracking systems,” a dispatcher told pilots approaching Chicago, according to audio published on ATC.com.
Flight tracking platform Flightradar24 recorded 3,100 aircraft airborne and heading toward U.S. airports when the ground stop order took effect. No additional aircraft took off while the restrictions remained active, the platform reported on X.
Modernization Funding and History of Nationwide Ground Stops
Congress approved funds last year to modernize aging communication architecture within the aviation administration. The agency and the White House subsequently requested additional funds from Congress to address broader systemic issues.

The disruption marked only the second time authorities halted nationwide departures since the terrorist attacks of September 11, 2001. A prior nationwide ground stop occurred in January 2023 due to a critical warning system failure.
