The Twin Otter is truly the small airliner that does it all. There is no aircraft that can land on tarmac runways, mudflats, water, sand, snow and ice. There is also no aircraft that does regular scheduled flights in both the Polar Regions, to airports at extreme altitude, tropical islands and to a beach in the UK. And it still does all that after decades or service. It is really a remarkable aircraft.
