Travelers at Central Wisconsin Airport in Mosinee faced delays on Friday, Nov. 13, as flights were held during a nationwide ground stop.

The Federal Aviation Administration pointed to a communication problem affecting air route traffic control centers. Aircraft were able to land, but departures were paused.

Six flights in and out of the Mosinee airport were held, including services connected to Chicago and Minneapolis.

Passengers bound for Chicago reported waiting more than two hours. One traveler said the delay was cutting into a weekend trip to see family in Pennsylvania, while noting the problem was not any one person's fault.

Transportation Secretary Sean Duffy said FAA technicians were investigating the communications issue affecting regional centers that direct aircraft between airports. The report noted this was the first nationwide ground stop since January 2023, when a key FAA computer system malfunctioned.
