Aviation crash in the US: The Federal Aviation Authority imposed a nationwide flight ban.
A significant disruption has occurred in the US civil aviation system. The Federal Aviation Administration (FAA) was forced to declare a nationwide "ground stop" "due to extraordinary circumstances and safety concerns."
The cause was attributed to overload and outdated telecommunications equipment. According to FlightAware, about 7,000 flights were delayed or canceled.
Planes that were already in the air had to wait for permission to land. The FAA later lifted the ban, but it will take time to restore the schedule, and the disruptions also affected Amtrak's website and app.
