US authorities called the cause of an unexpected large-scale violation of air traffic in the country

U.S. Transportation Secretary Sean Duffy said at a news conference that the massive equipment failure, which suspended departures from all U.S. airports for several hours, was the result of a technical error, not a cyber attack. According to him, the relevant services have not found any signs of outside interference and do not see the involvement of any foreign structures in the incident. The head of the department stressed that we are talking about the internal system of the Federal Aviation Administration (FAA) of the United States, which did not work properly.

As Duffy explained, at one of the remote facilities of the department, the employee carried out planned technical work to replace the communication line. L3Harris changed its copper cable to fiber optic cable. According to the minister, the replacement was performed improperly or a faulty router was installed during it, which led to a large-scale failure. The circumstances of what happened in the United States are still being investigated.

Duffy said flight control equipment has now been fully restored. However, he said further delays and cancellations should be expected. On November 13, the Federal Aviation Administration suspended flights from all airports in the country for about 4.5 hours due to a malfunction of flight control equipment.
