How about turning the mothballed 40% of the terminal into a landside aeroclub/pub/bar, reopen the "beer garden" it could attract a few people. Offer a happy hour, free parking etc... Never know.
If you look at the masterplan, it's more likely to become a community centre for the housing estate - Doctor's, nursery, etc
Parachute school should go down well with the new residents - what better on a summers weekend afternoon than to watch the pretty parachutes floating down.
Just add in the two based rapid-response helicopter units, what could possibly go wrong?
