40km Southeast of Moscow in the back corner of Zhukovsky International Airport, there is an an interesting remnant of the space race just left to rot. These are a set of 15 pictures taken by Aleksander Markin on this Flickr album. It shows a 1/3rd scale model of the Buran Orbiter. According to Markin, the replica is made almost entirely out of wood, and was used as a wind tunnel test when developing the aerodynamics.
When the Buran shuttle program fell into disarray, after the collapse of the Soviet Union, these prototypes and test were just left behind in the change. In the intervening years, they have been left the rot. Many shuttles and tests have been found by urban explorers, but many are still out there. In another recent post I talk about a similar Buran prototype left to rot away in an impressive warehouse. You can find that post here.
