Heliport
The supermarkets might have been persuaded to stump up some cash but the investment needed for anything meaningful in the harbour area would run into the millions. Any heliport there could only be on land reclaimed from the sea at vast cost. As I've already suggested, the setup costs of a new heli operation would be considerable.
I would be delighted to be proved wrong but if the most experienced operators of helicopter scheduled flights in the world could no longer make it work, it is difficult to see how any newcomers could do so.
