The reason for the failure in the air traffic control system was an overload of routers that were processing too much data. This is what US Transportation Secretary Sean Duffy said.
According to him, the equipment began to transmit conflicting information and therefore had to turn off the system.
Duffy noted that the problem of the aging infrastructure has been discussed with Trump for two years. He called on Congress to allocate $50 billion to modernize the air traffic control system.
