The SZD-42 Jantar 2 is a single seat Open Class competition glider, designed and produced in Poland in the 1970s.

Apart from the greater span, the wing of the Jantar 2 differed only from that of its predecessor by having less taper and a slight change of plan.

Combined with a carefully sealed sliding joint in the lower surface, these elastic flaps minimise loss in lift due to leakage and abrupt shape changes.

[1][2] The fuselage of the Jantar 2 has a central steel tube section, enclosed within a glass fibre epoxy shell which narrows aft of the wings.

[2] The two prototypes competed at the World Gliding Championships of 1976, held in Finland, with Julian Ziobro finishing in second place and Henryk Muszczynski third.
