The Skyvan was made by Short Brothers of Belfast, Ireland and it was the same Short Brothers as the famous British flying boats of World War Two.
While not the short field performer that the Twin Otter is, the 330 Skyvan was quite a decent STOL performer is its own right, and it could carry up to 30 passengers.
The final version of the Skyvan series was the 360 model which featured a single vertical fin and rudder as opposed to the H tail arrangement on the 330.
Shorts was the first true aviation company in the world, and was a manufacturer of flying boats during the 1920's & 30's and throughout the Second World War.
A Short Empire was used by BOAC for the first westbound transatlantic service from Foynes, Ireland to Newfoundland on 5 July 1937.
In the 1970s Shorts entered the feederliner market with their Shorts 330, a stretched modification of the Skyvan, called the C-23 Sherpa in USAF service, and another stretch resulted in the more streamlined Shorts 360, in which a more conventional central fin superseded the older H-profiled twin fins.
