Unfortunately Angelflight has been it's own worst enemy more than CASA destroying it. With at least two accidents where patients were killed and then claiming that CASA is responsible for the level of competence a pilot has, rather than having some form of review, training or checking system for its' own pilots. Aeromedical flights is a well known danger area for pushing into situations to get patients where they need to go and whilst this is not emergency transfers there is still a lot of pressure to get people where they want to be. Questions have to be asked why the service was needed at all for the Mt Gambier accident when they could have bought tickets on Rex for a few hundred $ and AF paid the tickets instead of a light aircraft.
If you operate a truck, bus, taxi and so on, you can't blame the road authority for driver standards, that's up to the operator to maintain. Even on the road hospitals and other healthcare services pay a high price for simple patient transfers by professional companies.
