Aero (2) Z-131
The Bücker Bü 131 Jungmann was a German two-seat basic training biplane from the 1930s so well liked that multiple countries kept building it under licence for decades after its debut. In Czechoslovakia, the state-owned Aero works built the type through the German wartime occupation and continued afterward with a locally sourced Walter Minor engine, after the pre-war firm Tatra had already licence-built a small batch as the T 131. Light, forgiving and fully aerobatic, the tandem-seat biplane trained generations of military and civilian pilots across Europe and beyond. Many Jungmann-family biplanes, original German and licence-built alike, remain airworthy today as prized vintage aerobatic mounts.
