Space Shuttle Buran (OK-1K1) was the first space shuttle run by Soviet Union. It flew one unmanned flight before being retired and was destroyed in a hangar collapse in 2002.
History.
The Buran was created in 1984. The first flight was an uncrewed orbital flight on November 15, 1988. There was also a plan for second flight of Buran. However, it never took place due to dissolution of Soviet Union. On May 12, 2002, the hangar where was stored the shuttle, was collapsed due to poor maintenance. The collapse not only killed the eight workers, it completely destroyed the shuttle and the rocket.
