Halas,
We're already in the process of a ground up airspace review at the moment, only because no one is willing to pay for outside help it's gonna be 3 - 5 years down the line.
Ah real shame as we needed it about 3 years ago!!
Oh and just to cheer everyone up, don't forget we'll be closing one of the runways 24 hrs a day shortly as it needs to be moved!! They never like to see us bored around here do they?
