The United States faced a major aviation crisis on Friday, November 13, 2026, after a nationwide communications failure forced authorities to suspend all departing flights. The unprecedented disruption stranded passengers and affected thousands of flights across the country.
The Federal Aviation Administration (FAA) ordered the nationwide ground stop after communication problems affected all 22 regional air traffic control centers.
The agency suspended departures shortly before 4 p.m. Eastern Time. Officials described the emergency measure as necessary to protect passengers and maintain aviation safety.
Aircraft already in the air could continue toward their destinations. However, planes waiting at airports could not take off.
The disruption caused widespread delays and cancellations at major airports, including those in New York, Chicago and Los Angeles.
Flight-tracking data showed that thousands of flights faced delays or cancellations. Airlines struggled to manage stranded passengers and aircraft waiting for departure clearance.
US Transportation Secretary Sean Duffy confirmed that technicians were investigating the nationwide telecommunications failure.
Homeland Security Secretary Markwayne Mullin said investigators had found no evidence suggesting a cyberattack or deliberate threat.
Officials also examined whether problems involving newer air traffic technology contributed to the failure. However, authorities had not confirmed a specific technical cause.
The incident raised fresh concerns about America’s aging aviation infrastructure. Air traffic controllers continue to rely on older communication systems despite ongoing modernization efforts.
The emergency marked only the second nationwide departure shutdown since the September 11, 2001, attacks. The previous incident occurred in January 2023.
The FAA lifted the nationwide ground stop at 8:15 p.m. Eastern Time, allowing departures to resume after more than four hours.
However, airlines warned that delays and cancellations could continue as they worked to restore normal operations.
The incident highlights growing concerns about the reliability of critical aviation systems across the United States.
