The Federal Aviation Administration (FAA) has implemented a nationwide ground stop for all airports across the United States. US Transportation Secretary Sean Duffy confirmed that the measure was necessitated by a communication issue impacting all air route traffic control centers. FAA technicians are currently investigating the root cause of the disruption.
In an official advisory, the FAA stated that traffic should remain ground stopped until further notice, noting that international flights are being managed on a case-by-case basis. According to data from the flight tracker FlightAware, the disruption has resulted in nearly 7,000 flight delays or cancellations nationwide. The agency emphasized that every flight has been accounted for and that the decision to halt operations was made out of an abundance of caution due to a temporary telecommunications outage.
Homeland Security Secretary Markwayne Mullin addressed the situation, stating that there is currently no indication of a nefarious attack. Mullin reassured the public that everyone is safe and encouraged people not to be fearful, explicitly stating that the incident is not a repeat of the September 11, 2001, attacks. While officials have not ruled out any possibilities, including the potential for a cyberattack, Mullin noted that he does not believe the air traffic stop is connected to the recent global Microsoft outage affecting other public services.
Mullin cautioned that the resolution process could take time, stating, "This isn’t going to just be resolved and turned around within the hour." Regarding the broader technical issues, "Those are separate issues," Mullin said. Mullin added that "every flight has been accounted for" and said incoming international flights would be handled on a "case by case basis." The last time a nationwide ground stop of this scale occurred was in January 2023, which was triggered by a pilot alert system outage. Prior to that event, such a measure had not been implemented since the 9/11 attacks.
The US government has been in the process of upgrading the aging technology used by air traffic controllers. Congress approved $12.5 billion for this project last year, which involves replacing miles of old copper wiring with fiber optic lines and updating legacy radio systems at airports nationwide. However, Secretary Duffy has indicated that an additional $30 billion will be required to complete the necessary modernization efforts, and the White House has begun lobbying Congress to secure that funding.
