The Albatros L 69 was a two-seat Germany parasol monoplane racing and training aircraft of 1925. It was a single-engine parasol-wing monoplane of conventional configuration that seated the pilot and passenger in tandem, open cockpits. It was advertised as a trainer, however contemporary reports dismissed this due to the difficulty in accessing the front cockpit, and the designers' focus on performance.[1]

Operational history

In 1925, the Albatros test pilot Kurt Ungewitter won Class D in the Deutsche Rundflug ("Round Germany") in an L 69a, but was killed in one in a crash two years later. The "Round-Saxony" flight Class D was won by a Bristol Lucifer-engined Albatros L.69, piloted by a student at an average speed of 165 km/h.[2]
