Nats 'regrets' chaos caused by computer glitch

Disruption at UK airports was caused by a computer system failure "which has not been seen before", National Air Traffic Services (Nats) has said.

The fault at the national air traffic control centre in Swanwick caused problems across the UK on Friday.

Nats chief executive Richard Deakin said he "regretted" the chaos, but added that the problem would not happen again.
