Well, it's not one of the shuttles but a Soviet Buran and it's also not the one that performed the only spaceflight of the ill-fated program 20 years ago - but one of the surviving prototypes, the No. 002 alias OK-GLI used in 34 taxi, approach and landing tests and later ending up in Bahrain's harbor. Having already made it to the Netherlands, on Monday it should start a journey up the Rhine river to its final destination, the Technik-Museum Speyer in Germany: While this semi-Buran is partially disassembled, as recent pictures show, it will at least be a strange sight (there is even a photo contest). Via a GPS receiver the convoy's position can be tracked in real time; due to motor problems of the vessel it's stuck in the Netherlands, though, for tonight, and may hopefully make it to Krefeld, Germany, on Monday.
