FAA grounds flights nationwide over air traffic communications problems
The FAA grounded flights across the US on Friday afternoon, citing safety concerns.
The problem involved communications at regional air traffic control centers, which direct planes between airports nationwide.
Transportation Secretary Sean Duffy said FAA technicians were investigating the issue.
A nationwide ground stop prevents flights from operating across the country while the FAA addresses a safety concern.
This was the first nationwide ground stop since January 2023, when a key FAA computer system malfunctioned.
Technicians are investigating, but no further details about the communications problem or when flights would resume were given.
The Federal Aviation Administration halted all flights at US airports on Friday, November 13, after a communications outage affected air traffic control.
The FAA said it acted as a precaution for safety and that every flight had been accounted for.
Transportation Secretary Sean Duffy said the issue affected all US Air Route Traffic Control Centers, and FAA technicians were investigating.
The disruption led to cancellations, delays and diversions, and airports in Toronto and Montreal also issued ground stops.
Homeland Security Secretary Markwayne Mullin said there was no indication the halt was due to a threat.

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.
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.
The current ground stop is not based on or a result of the SMART system, any product of ASI or our integration with FAA and ATC.
