US Airspace Paralyzed: FAA Grounds All Flights
The Federal Aviation Administration has grounded all domestic flights due to a critical communication system failure.

The US aviation industry is facing an unprecedented crisis. The Federal Aviation Administration (FAA) has made the decision to temporarily ground all flights across the country. According to the agency, this measure was taken due to "extraordinary circumstances and safety concerns." While aircraft currently in the air are being permitted to land, no new flights are departing from airports.
What actually happened?
US Secretary of Transportation Sean Duffy confirmed on the social network X that the massive disruption is linked to communication issues within air traffic control centers. Reports indicate that radio frequency connectivity was lost at several major centers, including Boston, Chicago, and New York. The FAA has not provided further details at this stage and remains unavailable for official comment.
Historical precedents
A total shutdown of this magnitude is extremely rare in American aviation. Historically, the FAA grounded all air traffic following the September 11, 2001, terrorist attacks. In the more recent past, a similar crisis occurred in January 2023, caused by a failure in the NOTAM (Notice to Air Missions) system, which provides pilots with real-time information and safety alerts.
The situation at airports
There is a chaotic situation at airports nationwide. For example, at San Francisco International Airport, passengers are queuing at airline desks, attempting to determine when flights will resume. It is worth noting that while some airports were already experiencing complications due to weather conditions, the FAA's decision has exacerbated the problem across the entire country.
United Airlines staff have already informed passengers in terminals that a "nationwide event" is occurring, meaning the disruption is not local in nature. At this time, it is unknown how long the airspace closure will last. Airlines and regulatory bodies are working intensively to resolve the technical fault, though a full restoration of flight schedules is expected to take several more hours.
