The US authorities have lifted the ban on the departure of planes from all airports in the country.
A statement issued by the Federal Aviation Administration. Transport Minister Sean Duffy blamed the incident on "instability in radar and communications systems".
"The flight ban to all airports was introduced following a communication problem that affected all regional air traffic control centers," he explained.
At a press conference in the White House, the head of the department added that inconsistent information began to arrive from radars. At the same time, the communication and radar capabilities were not completely lost. The US has an "incredibly old" air traffic control system, Duffy said. He estimated the modernization of the entire structure at 50 billion dollars.
