The Albatros L 68 Alauda, a German trainer aircraft from the 1920s, featured a two-seat design.
This single-engine biplane followed a conventional layout with tandem seating for the pilot and instructor in open cockpits.
The wings were characterised by unequal span and a noticeable stagger, distinguishing it from other aircraft of its time.
