It's interesting to note that there was a recent story that went around in September about the Buran being "rediscovered" in a junkyard. This is interesting since the traditional history of the Buran states that it was destroyed when the hanger it was stored in collapsed. I don't read Russian so it was hard for me to follow the story so take this with a grain of salt.
