Yes, and a helicopter is the much preferred type of aircraft in my view as they, in most cases, eliminate the need for a ground ambulance and can deliver the patient directly to the hospital facility. Further, establishing one or more helipads on the island could help in the event that someone is far from San Pedro and the air strip. I know there is at least one helipad up North here as I have used it and there are probably more.
I am against virtually any kind of tax and government involvement but this may be one time that a permanent fund could be set up and funded with donations and that fund tapped to pay for transport for those that cannot afford it. Donations could be made all through the year and not just when someone needed to be transported. This could also possibly serve other medically indigent persons.
