US Transport Secretary Sean Duffy linked the massive suspension of air travel to work to replace aging copper wires with fiber optics, the BBC reports.
According to him, due to the work, a problem arose in the router that began to overload air traffic control systems. This disrupted communication with the aircraft, and the authorities decided to close the airspace for safety reasons.
Duffy pointed out that the American communication system is very old, and the replacement of wires has been going on for several years.
A large-scale failure of the Federal Aviation Administration's communications systems occurred on November 14. The agency stopped flights from all airports in Israel for 4 hours.
