Air travel woes: Nats 'being squeezed financially'
Airports are returning to normal, apart from a small number of flight cancellations at Heathrow, the day after a computer failure at the UK's air traffic control centre.
National Air Traffic Services (Nats) said a technical fault in the flight data system at its Swanwick centre, in Hampshire, had caused the problem.
Former air traffic controller Martin Clipp told the BBC that safety had not been compromised, but warned that funding for Nats' systems "is being squeezed".
