US Flights Resume After Nationwide Grounding Caused by System Overload

US Transportation Secretary Sean Duffy said that the nationwide grounding of flights was caused by an overload of data in the air traffic control system and not by a cyberattack. The disruption occurred because the system handling air traffic operations relies on ageing technology that struggled to manage the data load, according to his explanation.

Flight departures were temporarily halted as a safety precaution, affecting air travel across the country. Duffy has since confirmed that flight operations have resumed. The incident has once again drawn attention to concerns about modernising the ageing technology and infrastructure used by the US air traffic control system.
