US domestic flights were allowed to depart again on November 13 after an hours-long nationwide ground stop caused by a telecommunications outage, according to CNN. Some flights resumed once the FAA lifted the order.
Transportation Secretary Sean Duffy blamed outdated air traffic control technology and overloaded routers for the disruption.
The incident follows a September 2026 telecom failure that disrupted Northeast air traffic, adding to scrutiny of the aging systems that underpin US aviation.
