At the height of the space race, the Soviet Union built an alternative to the American space shuttle. It was called Buran, it cost millions of dollars, and it only went up into orbit once. The whole space program it was part of was called off in 1991 when the USSR collapsed.
Since then, the Buran has been hiding inside the Baikonur Cosmodrome in Kazakhstan. It's a priceless piece of history, but it's been forgotten even by its own country.
