Federal Aviation Administration Issues National Ground Stop
The Federal Aviation Administration halted all departing flights across the United States on Friday due to a massive communications failure affecting air traffic control centers, CNBC Indonesia reported.
That rare nationwide order took effect just before 03.00 Jakarta time. It impacted every Air Route Traffic Control Center in the country, according to the Federal Aviation Administration.
Flight information boards displayed normal schedules while travelers found themselves unable to board their planes, CNBC Indonesia reported.
“We issued a nationwide ground stop order for all airports in the US following a communications issue that impacts all Air Route Traffic Control Centers,” the agency said.
Technical Failure Halts Traffic Across US Airspace
Technicians deployed immediately to investigate the root cause of the breakdown. The Federal Aviation Administration characterized the glitch as a temporary telecommunications disruption taken out of extra caution.
Secretary of Homeland Security Markwayne Mullin addressed public anxiety over the sudden halt. He confirmed that federal monitors detected no hostile indicators.
“This is not a 9/11 event,” Mullin said.
Mullin added that investigators found no signs of a malicious cyberattack. “This is purely a telecommunications disruption,” he told CNBC Indonesia, though he noted officials would not rule out any possibilities.
Nationwide Flight Halt Disrupts Domestic Airline Schedules
Flightradar24 data showed 4,042 aircraft airborne and heading toward destinations across the United States when the directive came down, according to Flightradar24.
Robert Mann, an aviation analyst, said that if the halt extended into the evening, recovering airline schedules would likely require the entire weekend.
Federal officials confirmed that this shutdown marked only the second time all domestic departures were halted nationwide since September 11, 2001. A similar disruption occurred in January 2023, lasting less than two hours.
