BRITAIN-AVIATION

An information board displays news about delays to departures in the south terminal at Gatwick Airport, south of London on December 12, 2014. A computer failure at an air traffic control centre sparked travel chaos in Britain on Friday as the peak Christmas season gets underway, officials said. Heathrow Airport, Europe's busiest hub, said 50 flights had to be cancelled and warned passengers to check their flight status before setting off. After more than an hour in which some departures were blocked and arrivals diverted, Britain's National Air Traffic Services (NATS) said the system had been restored and services were returning to normal.
