Korolev studied specialized aviation topics until 1929, while living with his family in the typically crowded conditions of Moscow. Korolev enjoyed opportunities to fly gliders and powered aircraft during this part of his education. He designed a glider in 1928, and flew it in a competition the next year. The Communist Party accelerated the education of engineers in 1929 to meet the country's urgent need for their skills. Korolev obtained a diploma by producing a practical aircraft design by the end of the year. His advisor was the famous Andrei Tupolev.
