One of the developed versions of the popular "Jaskółka" (swallow) glider, was the "Jaskółka L". In the half of the 1950s, the group of the Bielsko-Biała SZD designers led by engineers: Tadeusz Kostia and Jan Dyrka, basing on the "Jaskółka" construction, designed a glider with the laminar aerofoil and the "butterfly rudder" (so called the Rudlicki's rudder), tested already on the earlier, the SZD-14 "Jaskółka M". The prototype flew in March 1956.
The "JaskółkaL" was intended to be a high performance glider for the Polish pilots participating in the world championships. The glider however did not fill up the expectations - only 4 examples were built. Flying the SP-1506 "Jaskółka L" (now displayed at the museum), the Polish pilot Tadeusz Góra established in 1956 a cross-country speed record.
