The Federal Aviation Administration (FAA) slowly resumed departures of U.S. flights after lifting its ground stop order caused by a system outage. Up to 32,578 flights were suspended into, within or out of the United States as of 8:07 AM. “The FAA is still working to fully restore the Notice to Air Missions (NOTAM) system following an outage. While some functions are beginning to come back online, National Airspace System operations remain limited,” the FAA tweeted.
