Don't keep knocking SERCO. They are good at what they do. Air traffic is NOT their business, making money is.
Why would they want to be the knight in shining armour when you can make more money by waiting for NATS to be kicked totally to the ground, then pick over it's bones like a vulture.
That's what SERCO do. They buy, rip the guts out if there are any left, do it cheap, and make as much money as possible.
They have no interest in a quality service, mind you has NATS in the current mindset?
Money, Money, Money. That's what it's all about. Wake up you lot.
