A technical issue led to flight delays briefly in Britain on Wednesday before the engineers were able to restore the system, the  air traffic control operator said. According to a report by Aljazeera, the National Air Traffic Service, or NATS, reported a “technical issue”, but later said the glitch had been resolved. In a statement, it later said that departures at all airports have resumed and that teams are working with affected airlines and airports to “clear the backlog safely.”
