CCCP-3501002 (cn 0.02) This spaceframe, built in 1984, was designed for aerodynamic and landing tests. Therefore it was equipped with four AL-31 jet engines, two of them are still visible. The first flight was Nov. 10, 1985, last flight Apr. 15, 1988. Note the faded CCCP marking on the wings. Here the Buran orbiter just passes the "Flehe bridge" on river Rhine (km 732) near Dusseldorf.
