LONDON (Reuters) - Thousands of travelers were delayed at major airports across England on Saturday because of a technical problem at an air traffic control centre. Disruption was reported at most airports including Heathrow, Gatwick and Stansted, after what National Air Traffic Services (NATS) said was a computer glitch at its control centre in Swanwick in Hampshire. Heathrow, Britain's busiest airport, had canceled 60 flights by 0945 GMT, a spokesman said. Edinburgh, Manchester, Birmingham, Southampton, Luton, London City, Newcastle, Exeter and Bournemouth Stansted also reported delays and were asking passengers to check with their airlines. Flights from Scotland were less affected. The problem was fixed after 12 hours. 1,300 flights were severely delayed, 8 percent of the European daily total.
