The OK-GLI (Russian: Орбитальный корабль для горизонтальных лётных испытаний, ОК-ГЛИ, romanized: Orbital'nyy korabl' dlya gorizontal'nykh lotnykh ispytaniy, lit. 'Orbital ship for horizontal flight tests'), also known as Buran Analog BST-02 (БТС-02), was a test vehicle ("Buran aerodynamic analogue") in the Buran programme. It was constructed in 1984, and was used for 25 test flights between 1985 and 1988 before being retired. It is now an exhibit at the Technik Museum Speyer in Germany.
The development of the Buran began in the late 1970s as a response to the U.S. Space Shuttle program. The construction of the orbiters began in 1980, and by 1984 the first full-scale Buran was rolled out. The first suborbital test flight of a scale-model took place as early as July 1983. As the project progressed, five additional scale-model flights were performed.
The OK-GLI (Buran Analog BST-02) test vehicle ("Buran aerodynamic analogue") was constructed in 1984. It was fitted with four AL-31 jet engines mounted at the rear (the fuel tank for the engines occupied a quarter of the cargo bay). This Buran could take off under its own power for flight tests, in contrast to the American Enterprise test vehicle, which was entirely unpowered and relied on an air launch.
The jets were used to take off from a normal landing strip, and once it reached a designated point, the engines were cut and the OK-GLI glided back to land. This provided invaluable information about the handling characteristics of the Buran design, and significantly differed from the carrier plane/air drop method used by the US and the Enterprise test craft.

Zhukovsky Air Base
In 2000, the OK-GLI was sold to an Australian company called the Buran Space Corporation, owned by Australian astronaut Paul Scully-Power. It was disassembled and transported by ship to Sydney, Australia, via Gothenburg, Sweden; arriving on 9 February 2000 and appeared as a static tourist attraction under a large temporary structure in Darling Harbour for a few years.
Upon reassembly, the OK-GLI was put on display in a temporary enclosure for the 2000 Summer Olympics in Sydney. Visitors could walk around and inside the vehicle (a walkway was built along the cargo bay), and plans were in place for a tour of various cities in Australia and Asia. The owners went into bankruptcy after the Olympics, and the vehicle was moved into the open air and stored for a year, in a fenced-in parking lot and protected by nothing more than a large tarpaulin, where it suffered deterioration and repeated vandalism.
It was then bought by the Sinsheim Auto & Technik Museum, to be transported to Germany in 2005. Due to legal issues, it remained in Bahrain for several years, pending settlement of an international court case over fees.

The journey got off to an inauspicious start when, during the transfer from the storage barge to the ship, there was a failure of the aft spreader (part of the lifting mechanism) and the tail of the vehicle dropped from just above deck height to the bottom of the hold. No one was hurt and both the ship and vehicle seemed to suffer only minor damage.
