America's nationwide flight shutdown on Friday was triggered by work to replace ageing copper telecoms wiring with fibre, US Transport Secretary Sean Duffy said. A router fitted by contractor L3Harris flooded air traffic control systems, so the airspace was closed for over four hours. Officials see no sign of a cyber-attack. Over 3,500 flights were cancelled on Saturday, with disruption expected to last for days.
