Don't forget the NIMBY's
I wonder how the folk at ST Erth would respond if you told them these two things:
1. There WILL be a heliport at St Erth.
2. A Landing fee will be charged for every movement and a share paid to each household within 1 mile (?) of the new heliport. If just one pound per ticket were added for this 'solidarity' fund it would easily generate a sizeable fund each year. At the height of the season the old PZ operation was flying 24 rotations a day (2 aircraft). Sixteen seats per rotation so at a rough guess you might be able to give each household (I am guessing 40) a couple of hundred pounds a month. The reward would be proportional to their pain.
Then add the fact that from St Erth there could be four outbound and four inbound routes that will be used in rotation to minimise the flyover noise issues. The speed of modern helicopters makes small variations in routing hardly noticeable on the bottom line.
The Islands are a regional asset and they need a direct service from a railhead. West Penwith could capitalise on this regional asset and profit by it.
The money needs to come via the Islands and may be available from European Development funds?
