The DHC-6 Twin Otter is a 20-passenger STOL (Short Takeoff and Landing) utility aircraft developed by de Havilland Canada. It has often been called the most successful aircraft program in Canada's history. The
aircraft's fixed tricycle undercarriage, STOL abilities and relatively high rate of climb have made it a successful cargo, regional passenger airliner and MEDEVAC aircraft. In addition, the Twin Otter has been popular with
commercial skydiving operations.
The Twin Otter made it's first flight on 20 May 1965 and is still in service all over the world.
Refurbished DHC-6's are so now much in demand that Viking Air have
commenced manufacture of new aircraft, this new version is designated the
Viking DHC6-400
