I'd be interested in your comments on some of the freshly graduated Indo pilots , why aren't more flying with Susi Air ?
I think your previous lines explain it all. I have met a few guys who started on Twin Otters out of flight school but jets is where its at so to speak. They are generally disinterested in flying a single-engine turbo-prop.
There are Indonesian pilots currently and I certainly wish there were more because it is enjoyable flying and I know some people who skipped straight to jets say they feel they have missed out. Off the top of my head 2 trained outside of Indonesia.
