US Air Traffic Paralyzed: Nationwide Ground Stop Imposed on All Flights Following Telecommunications Failure

The United States Federal Aviation Administration (FAA) issued a comprehensive and immediate nationwide ground stop order affecting all American airports, following a technical failure in the telecommunications network that directly impacted air traffic control centers across the country.

US Transportation Secretary Sean Duffy announced on his account on the platform "X" that technical teams from the aviation authority immediately launched investigations to determine the causes of the malfunction and resolve it, stressing that authorities will provide updates to the public and airports as soon as they become available.

Suspension Until Further Notice and Special Procedures for International Flights

According to an FAA statement reported by US media, including CNN, authorities emphasized that air traffic would remain suspended until further notice, with a mechanism established to handle inbound international flights to the United States on an individual, case-by-case basis. The agency justified the comprehensive halt by citing "extraordinary circumstances" and imperatives related to the safety and security of air navigation.

Data from the aircraft tracking platform "Flightradar" showed that approximately 4,042 flights were airborne heading toward US airports at the moment the sudden ground stop order was issued, casting a shadow over transatlantic travel and passenger itineraries worldwide.

Imminent Attack Hypothesis Dismissed as Investigations Continue

For his part, US Secretary of Homeland Security Markwayne Mullin stated to reporters at the White House that there are currently no indications pointing to a targeted security threat against the country causing this crisis, emphasizing: "This is not a 9/11-style event," while not ruling out the possibility that the outage was caused by a cyberattack until ongoing inquiries conclude.

In a subsequent clarification on "X", the FAA confirmed that the decision for the nationwide ground stop was taken "out of an abundance of caution" following a temporary telecommunications outage. It is noted that the US aviation sector experienced two similar communication system failures in 2025, which disrupted flight operations at Newark Airport, one of the three major airports serving New York City.
