Nationwide FAA Ground Stop Lifted After Communications Outage, Flights Resume with Delays

A nationwide ground stop, implemented on Friday due to a major communications outage caused by overloaded antiquated air traffic control systems, was lifted on Saturday. Flights have resumed across the United States, but authorities warn that returning to normal operations will take time, with thousands of flights canceled and delayed. Homeland Security Secretary Markwayne Mullin ruled out a cyberattack or national security threat, while Transportation Secretary Sean Duffy attributed the disruption to a failure of aging network technology.
