Aero Linx: The Lake Amphibian Flyers Club The Lake Amphibian Flyers Club is an international organization of owners, pilots, and aficionados of Lake Amphibian aircraft. This unique airplane can do what ordinary airplanes cannot do. Once you have flown a Lake, an ordinary airplane will seem mundane.
