the ideal place for this would be Thorney Island
I have often thought that! It is a lovely part of the world...
The only issue I really see is that there is very sparse alternative transportation methods from the airfield. Also - if people do base their planes there, the only transportation there is by car, and that takes over 2 hours... Much longer in traffic (I know - I used to drive regularly to Hayling Island, just down the road).
Good news if the airfield is there to stay!! I do think they should consider building houses on the outskirts of the airfield, that'd be perfect!!!
