This is a universal single seater performance, all wooden glider in a cantilever mid-wing configuration. The wings are equipped with the slotted flaps and plate air breaks.
The design works started 1950 at the Construction Bureau of the Gliders Experimental Works in Bielsko Biała. The chief designer was engineer Tadeusz Kostia. On 21st September, factory test pilot - Adam Zientek flew the "Jaskółka" (swallow) for the first time. The test flights revealed wrong transversal manoeuvrability and troubles with the rich (as for that time) cockpit equipment. Another danger was a glider's tendency to a flat spin and significant stick load.
After necessary improvements and completed tests the glider was introduced in 1953 into serial production under the SZD-8 bis "Jaskółka" designation. The first production series counted 30 examples. As a result of the experiences gained during service and changing technical requirements, several derivatives of this glider (the "Jaskółka bis O" and "Jaskółka ter Z") appeared.
Until the end of the 1950s, 150 "Jaskółka" gliders in different versions were built (also for export). In the fifties it was the most popular Polish performance glider, widely used at the aeroclubs. Many domestic and international records were established on it, during the gliding championships.
