The Dornier Libelle (also known as the Do A) is an early, open-cockpit German flying boat designed in the 1920s.
It is frequently on display at the Deutsches Museum in Munich, Germany, which features the aircraft’s iconic, lightweight metal hull, sponsons, and parasol-wing layout.

The Junkers F 13 is known for its distinctive corrugated metal skin, which provided the aircraft with great stability despite its lightweight aluminum construction.
The specimen on display in the museum bears the historical registration D-366.
