The US Secretary of Transportation: the suspension of flights was not caused by a cyber attack / all planes landed safely.
The American Secretary of Transportation said about the disruption of flights in this country: when the flight suspension order was issued, 3,500 planes were in the sky and all planes landed safely.
Our air system has been worn out for decades. In addition to the equipment, our communication system is also very old.
All US agencies have switched their systems from copper to fiber optics, and the US Air Force is almost the last agency to do so now. Yesterday's incident and the suspension of flights happened because of these changes.
This incident was not caused by a cyber attack./Jamran.
