The Caproni Vizzola Calif was a family of Italian
chord and trapezoidal outer panels. The forward fuselage was constructed of fibreglass over an alloy frame, while the rear fuselage, wings, and empennage
were metal-covered.
The most significant member of the family, and the only one produced in quantity (around 150 by the early 1980s) was the A-21S, a two-seat version that accommodated the pilot and passenger side by side. At one time this aircraft concurrently held four world records for two-seat sailplanes, including:
- the women's closed-circuit speed record set by Adele Orsi and Franca Bellengeri in August 1974
- straight distance of 970.4 km by Ingo Renner and Hilmer Geissler in Australia in 1975
