WASHINGTON, January 11. /TASS/. Normal air traffic is gradually resuming in the United States, with the previously imposed ban on domestic flights having been lifted, the US Federal Aviation Administration (FAA) reported on Twitter.

"Normal air traffic operations are resuming gradually across the US 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," the report said.
