In the United States, flights from all airports were suspended for several hours due to a malfunction in the communication system.
The US Federal Aviation Administration (FAA) introduced on November 13 a nationwide ban on aircraft departures from all airports in the country, the media reported.
According to US Transportation Secretary Sean Duffy, the restrictions were due to a communications failure that affected all regional air traffic control centers. The planes in the air were allowed to land. According to data from the flight tracking service, thousands of flights were canceled during the ban, and about 10,000 more were delayed. The disruption also affected international air travel: the European Air Navigation Safety Organization suspended flights to the United States.
The US Department of Homeland Security said there was no indication of a malicious attack. According to media reports, one of the verified versions is a failure after updating the private communications network connecting the launch nodes.
More than four hours later, the restrictions were lifted and air traffic was restored.
