In 1921, with the help of some fellow students, Vladimir Sergueyevich Pyshnov built his first glider. In November of this year on this glider a group of young students, including Pyshnov himself, BI Cheranovski, VN Belyayev, VV Utkin-Yegorov and others, made more than 20 flights. In the last one carried out, the glider was destroyed and was never restored.
