Dunno Wally, I think there may even already be a couple of orders (at least serious expressions of interest when they open the order book anyway) for these things by RFDS.
I agree. Given they have helped design the thing I would imagine they may have some sort of option. RFDS are the biggest operator of the PC12 so a obvious place to try and move new product. The PC24 could kill off the pesky Kingair that inhabits the East Coast aeromed operators as well, so Australia is a good market for them.
However they do have to build it. Hopefully it won't be another Eclipse!
