Airlines cancel flights as FAA outage threatens daylong disruption

Airlines have canceled flights scheduled to depart later Friday following the FAA's nationwide ground stop, and American Airlines expects disruptions for the rest of the day, Ars Technica reported. Homeland Security Secretary Markwayne Mullin warned that resolving the outage would take time. Transportation Secretary Sean Duffy attributed the halt to a communications issue affecting all Air Route Traffic Control Centers and said FAA staff were troubleshooting it. Mullin said there was no indication of a malicious attack and that incoming international flights would be handled individually.
