Class ?? airspace
ATCBabe - Like others I do believe you are kidding in your quest for more controlled airspace. (I do hope so) I think it would be an absolutely splendid idea if airports had to pay "rent" on the volume of airspace they want for their own control. how much would then be relinquished in a hurry and suddenly become open FIR?
We can all think of examples but what is your worst one?
