The jolly Trislander. The third engine is there to overcome the drag of the third engine. :diablo:

Which leaves you with an Islander.

I flew on a Great Barrier Airlines Islander once, with a crate of fish and one other person in the cabin. The weather was poor and the flight extremely rough but the pilots did a great job – real seat-of-the-pants flying.

I don’t remember Great Barrier Airlines having a problem back in those days (1990) but I do remember the aircraft having to operate in very difficult conditions. Great Barrier Island really is back-and-beyond Hicksville and the airstrips aren’t much.
