Outdated air traffic control system causes major disruption in US

Causes of the technical failure

The temporary complete suspension of flights within the United States was the result of overloaded outdated air traffic control infrastructure. This was announced by US Transport Secretary Sean Duffy.

According to the official, key components of the system — switches and routers — were unable to process the flow of incoming data. This caused the equipment to begin transmitting conflicting information.

Status of air traffic

The official ban on aircraft take-offs has now been lifted, and airlines are gradually restoring their flight schedules. However, delays and flight cancellations may continue for some time.
