Russian manned spaceplane. This Buran OK-GLI 'Analogue' was a version of the Buran spaceplane equipped with jet engines to allow it to be flown in handling and landing system tests at subsonic speed in the earth's atmosphere.

It had the same aerodynamic, center of gravity, and inertial characteristics as the orbiter.

Its main purpose was to conduct the repetitive tests necessary to develop the automated landing system. The OK-GLI differed from the space-rated orbiters in being equipped with four AL-31 turbojet engines, with a total thrust of 40 metric tons, mounted at 4 degrees off the horizontal axis. These allowed the analogue to take off from conventional air fields. After reaching 5,000 m altitude, the engines would be shut off, and a manual or automatic landing would be accomplished. The analogue was equipped with the same essential systems as the orbiter, including the RM-1 and RM-2 ejection seats, the GSP and VIU navigation systems; the landing gear, landing system antennae, thermal sensors, and first and second group accelerometers. Prior to completion the OK-GLI was used on the 3M-T transport to test fight characteristics of the 3M-T/orbiter combination, the OK-launch vehicle interface attach points, and to develop the optimal transport configuration. It had been claimed that some of these tests were to be manned, and that on the first such flight cosmonauts Georgi Shonin and Yevgeni Khrunov were involved in an accident when the 3M-T ran off the runway. However it was now known that the payload capacity of the 3M-T was limited to 50 metric tons, so this story seems unlikely (an empty orbiter would weigh at least 70 metric tons). After these tests the OK-GLI was returned to the shop for completion. Thereafter it began a series of test flights to verify the subsonic aerodynamic characteristics of the design and develop the manual and automatic flight and landing systems. The aircraft was retired to the Zhukovskiy test center near Moscow, where it was often rolled out for exhibition during air shows.
