Heathrow and Gatwick flights affected by air-traffic controllers' computer 'glitch'

NATS admits computer problems at its Swanwick computer centre - but UK airspace not closed

Flights into and out of southern England have been severely restricted today as a result of a computer "glitch", according to NATS (formerly National Air Traffic Services), the UK's air navigation service provider.

The national air traffic control body said it was working to restore full operations at its Swanwick control centre but UK airspace was not closed.

In a statement released today, it said: "NATS is experiencing technical problems at our Swanwick control centre and we are working to restore full operations.

"This has not resulted in the closure of UK airspace or the suspension of all flights in or out the UK.

"However, to maintain safety NATS is restricting the number of aircraft flying across the south of England and those taking off from airports. We regret any inconvenience this may cause however our first priority will always be the safety of the flying public.

"NATS is taking every step to restore services and has contingency plans in place to minimise any disruption."

The glitch has affected aircraft taking off from London airports at Gatwick and Heathrow, the two busiest airports in the UK.
