Unless the bowser flys i will be flying the plane with you!!
I am not sure about the diesel engine, i don't think they have been in aviation service long enough to fly in all those cold climates. I don't want my fuel turning to jelly.
The next question is:
Do we
A) Get a nice new plane with all the mod cons
b) Go balls to the wall and get an old shed with minimum IR equipment
I would go with option B somthing like an old supercub with tundra tyres, that way you can land on sixpence if you need to.
