US flights resume after FAA lifts hours-long nationwide ground stop

US aviation authorities imposed a nationwide ground stop on departures across the United States on Friday afternoon, described by multiple outlets as an extraordinary safety measure tied to disruptions in air-traffic-control communications. The stop halted outbound flights nationwide, with aircraft already in the air allowed to continue under the last assigned clearances. The directive did not specify an end time in initial advisories.

The FAA lifted the nationwide ground stop after assessing evolving safety concerns related to the broader communications outage that disrupted air-traffic-control operations across the country. The ground stop’s termination enabled flights to resume services across the United States, though reports indicated that delays and backlogs were expected as schedules recovered.

O’Hare International Airport in the Chicago area was highlighted as a notable carve-out location during the halt, with departures paused in a mid-afternoon window from about 1:00 p.m. to 2:15 p.m. local time due to nearby thunderstorms. Several outlets noted weather contributed to the ground stop’s impact at that hub. (Sources: Audacy, 5newsonline.com, Open Jaw via Chicago-area reporting)

The stoppage was described as affecting all flights operating within or departing U.S. airspace, with international arrivals to be processed on a case-by-case basis as the FAA restored operations and evaluated safety concerns. Dispatchers were expected to rely on ATC Zero-style procedures during the halt, meaning no new departures would be cleared while the airspace and systems were assessed.

The reporting consistently stated that there were no injuries, fatalities, or aircraft accidents associated with the ground stop or the concurrent weather event in early updates. The FAA and other authorities continued investigations and provided updates as guidance evolved, with the overarching characterization of the action as precautionary and safety-focused while they worked to restore normal operations.
