Actually, not one iota of your tax payer money goes towards it
Not true.
Apart from the billions of pounds worth of infrastructure inherited by NATS when it was privatised. They didn't build the ATC system from scratch, my tax pounds gave them a huge leg up ;-)
The government still owns 49% of NATS and was given £65 million of my money after Sept 11th. What of the current £1bn investment programme, isn't some of that funded from the government purse?
