This is a two seater all wooden, training glider built in strutted high wing configuration and a fuselage of polygonal section. Design of the Czapla (heron) was carried out at the SZD in Bielsko - Biała in 1952 - 1953 as an order of the Friends of Soldiers League - a paramilitary organisation which also carried out an aviation training for youth at the aeroclubs.
The new construction was intended for the rubber ropes, winch or aircraft take-off and for the basic aerobatics. The glider's designers were engineers: Roman Zatwarnicki, Irena Kaniewska and Marian Gracz.
The prototype of the Czapla flew in November 1953, however it appeared, that the construction requires introduction of several improvements. The built of the second prototype ended 1954. After next changes, concerning ailerons construction and air brakes, the glider was introduced into serial production as the SZD-10 bis "Czapla". It was cheap and simple construction.
The "Czaplas" were produced in big quantities at the Sport Aviation Gliders Works (the ZSLS) in Krosno, at the ZSLS in Wrocław and at the Military Repair Workshops in Łódź.
The gliders were used at the aeroclubs until the beginning of the 1980s. They were also exported to Finland and Turkey.
The displayed SP-1477 SZD-10 bis "Czapla", flew with the Krakow Aeroclub until 1972.
