A UK flight-management system suffered a major outage on the afternoon of the 8th after a UK military aircraft submitted what media described as 'false' flight data, shutting the system for about four hours and leading to the cancellation of more than 2,000 flights and the disruption of hundreds of thousands of passengers, the Guardian reported. The Financial Times, citing four people, said the military flight plan triggered the system collapse and it remained unrepaired for hours. The UK Ministry of Defense said it had seen no evidence of military wrongdoing; National Air Traffic Services is investigating.
