When Pigs Grow Wings and Fly

Not exactly a mythical creature, but definitely the result of someone's flight of fancy. I dislike the name "pigasus" and gladly defer the use of that name to another flying pig model designed by Bridget Hayes. (Mark Morden, who drew the diagrams for this model, should be putting the diagrams back online soon.)
