The Buran hangar collapse was a structural failure of the hangar supporting the Buran spacecraft on May 12, 2002 in Kazakhstan. The collapse killed 7 workers and destroyed the orbiter as well as a mock-up of an Energia booster rocket.[1]
It occurred at building 112 at the Baikonur Cosmodrome, 14 years after its first and only flight. The roof collapsed due to poor maintenance. Work on the roof had begun for a maintenance project, whose equipment is thought to have contributed to the collapse. Also, preceding May 12 there had been several days of heavy rain.[2]
