We're not talking a routine scheduled service, but an occasional emergency one. As you can tell from Amanda's post, it is possible to land at SP (& more importantly, take off again) with a small jet such as a Gulfstream. I don't know what jet the medical services use, and it's a question of fact whether it can use SP. Also whether fuel is available. Maybe they can post a reply? The SP strip is actually quite long and I should think there's a good chance.
