A radar-related technical issue in Britain's air traffic control system disrupted flights for over four hours at major airports in London and elsewhere on Wednesday, though the issue was later resolved and departures were resuming.
"Our systems are fully operational and air traffic capacity is returning to normal," NATS, the country's air traffic control provider, said in a post on X.
"Departures at all airports have resumed and we are working with affected airlines and airports to clear the backlog safely. We apologise to everyone affected by this issue."
