Once had a Trislander pilot give us abuse in the Shed, something along the lines of "..with the box in sight etc.." To which the only reply I could come up with was "We're not just a box, compared your thing we're a turbo box GTI!"
Any aircraft a Trislander pilot can take the p*** out of really has to be ugly! The Skyvan is the real ugly duckling of the Shorts family, though I'm not sure if what it grew into (SD 3-60) was any better!! Certainly no swan....
