On November 13, 2026, a nationwide ground stop was issued for all flights in the United States, the largest since the 9/11 attacks in 2001. From this event, a few things should be clear. Only DOMESTIC flights were grounded in the United States. International flights are operating normally in America. For example: Virgin Atlantic flight 23 from London Heathrow bound for LAX is not being diverted at this moment. It is scheduled to reach on time. However, JetBlue flight 23 from Washington D.C., bound for Palm Beach, has been delayed by 10 hours and 34 minutes as it is a domestic flight.
CAUSE
The cause is still unknown, but it is believed to be a problem regarding the National Weather Service (NWS) of the U.S. having an outage earlier. It is not known to be a result of Artificial Intelligence or new software trials by the FAA.
