Even if a big bag of cash was found and the road/rail links improved, there looks little room to slide the runway Westward on extension to increase overflight heights of Ramsgate residents.
Either locals are 'for' it or 'against' it so little point Thanet CC and locals having an appetite to keep it an airport (or do they mean a large area of nothingness?) if night flights not acceptable.
I know a company that are looking for such a facility in SE UK but couldn't be expected to make it work with such a restriction.
