In general, patients in fixed wing air ambulance operations are more stable than those who need rotor wing medivac. In my opinion, those who fly their choppers are true unsung heros. I would also like to say flight nurses in this field are equally or even more courageous and skilled in their own profession.
From Reno to SLC in the snowy wx by PC-12. Who knows what was the true reason for this medivac ops. As 20driver mentions, I have heard many stories of lucrative deal in air ambulance ops, especially with Native American/First Nation contracts.
