Like the splash page, lots of commanders.  Always wonder why they buy the jetprop models for this type of mission when I assume a cheaper -5 690A/B would fill the job description.
Looks like they also have a 900 N3NT

Bruce can probably give a better answer than I can, but I believe that the Jetprops are, in the long run, cheaper to own and maintain than the 690A/B.
