The Dornier Libelle (en:"Dragonfly I"), also designated Do A, was a German open-cockpit, all-metal, parasol wing, monoplane flying boat aircraft, with partly fabric-covered wings. There was three versions of the seaplane version; the prototype, first version, and improved version (the Libelle 2). A landplane version, built without sponsons and fitted with a fixed tailwheel undercarriage was produced as the Dornier Spatz.[1]
