The Swift S-1 is a single seat aerobatic glider manufactured by Polish company Swift Ltd.

Design and development

Edward Margański, Jerzy Cisowski and Jerzy Makula developed the Swift at Bielsko-Biała from the SZD-21-2b Kobuz 3. The prototype first flew in 1991.

The glider is made of glass-fibre epoxy composite. It is very strong (stressed for plus and minus 10g) and manoeuvrable (a roll takes less than 4 seconds). Larger tips to increase the span to 15m were designed but not made. It has a retractable undercarriage.
