Sorry, not Andrew.
I've spoken to ISC and they say that there is no recollection of a Dash 7 ever operating a passenger service into St Mary's. A British Antarctic Survey aircraft did once land there but only for an air show.
As regards a Jetfoil, I think it would be admirable for a couple of summer months but I doubt it would prove profitable at any other time. In winter, total passenger numbers are in the tens. It would be an enormous investment for a market limited to about seven months a year.
At present a fair percentage of visitors have to travel to Lands End airfield anyway. The costs of operating PZE heliport from the income of one company is a a huge burden. Pehaps the two companies, BIH and Isles of Scillies Steamship Co, calculate that together, even in competition, they will do better.

Hadn't heard about Air France Transalls. They would be far too big other than possibly for a couple of summer weekends.
