We (ATC Tech Committee) tried for years when I was up in your neck of the woods to get the Class E upgraded to D without success. Does nothing ever change?
Since I'm an ATCO, I know the answers to your questions, so I'll leave the flyboys and girls to have a go.
Come on have a guess, you'll be surprised!!!
(BTW passepartout, I think we may know each other but I'm not certain. Did you get caught for a minor traffic violation whilst living north of the River?)
