Keep the Skinny Birds Flying Safely
I was cleaning some shelves in a closet and found an issue of Sport Flying that my dad saved. It has an article on the Porterfield Aircraft Company in it.
I remember there being much discussion around the article at our house. I think that the author of the article, Don Pratt, may have contacted my dad about the history of Porterfield. I cannot be sure however as at this time I was just graduating from college and getting my first job.
