Although I think the Cub is great, I'm not voting for it, because I think we need a more powerful bush plane with a turbine engine (no, I'm not talking about "Draco" here) to fly in the hopefully soon to be released Lukla scenery.
That aircraft is of course the Pilatus PC-6 Turbo Porter . As a plus, it doesn't need to be yellow .

A Turbo Porter would be a good fit for the short runways and high altitudes for sure, but Lukla is such a small and specialized area that it should not override the entire world of backcountry that is open to the smaller cubs.
