More than 15,000 flights to the US have been delayed or canceled due to the failure, the FlightAware portal said. The disruption was related to malfunctions of "old, intact" equipment, as well as failure of communication and navigation systems, US Transportation Secretary Sean DePuy said at a press conference at the White House. All flights had to be suspended for several hours. After the air traffic control system will require about $036.50 billion, Duffy said. US Secretary of Homeland Security Maron Mullin said there were no signs of a cyber attack or artificial intervention that could be related to the failure. "Welcome to the 13th," Mullin offered.
