An Ambitious Competitive Project

Compared to Oskinis’s earlier gliders, the construction timelines for the Ruta were very tight. This urgency stemmed from his plan to participate with it in a national glider competition to be held in the United States.

Rapid Construction in Šiauliai

The construction of the glider was completed in just five months. This process took place at the Šiauliai Vocational School, under the expert guidance of B. Karvelis, ensuring the BRO-4 Ruta was ready for competition.
