“A Notice to Air Missions alerts pilots about closed runways, equipment outages, and other potential hazards along a flight route or at a location that could affect the flight,” the FAA explained, continuing to report its progress throughout the morning.

The FAA initially announced that departures were resuming at Newark Liberty International Airport as well as Atlanta, and in a fifth update posted at 8:50 a.m. ET, the FAA reported that “normal air traffic operations are resuming gradually across the U.S. following an overnight outage to the Notice to Air Missions system that provides safety info to flight crews.”

“The ground stop has been lifted. We continue to look into the cause of the initial problem,” it added:

However, the outage has caused mass delays across the country. As of 11:20 a.m. ET , there were 6,477 delayed flights within, into, or out of the U.S. U.S.-related cancellations, as of that same time, stood at 1,052:
