Soyuz 21 (Baikal)

The 7K-T No. 64 spacecraft was launched in Jul 1976, carrying Boris Volynov and Vitaliy Zholobov. It was named Soyuz-21 on reaching orbit. The spacecraft was an 11F615A9 variant (although some records say Soyuz-21 was an A8, 7K-T No. 41). During undocking on Aug 24, the latches failed to separate for about an orbit.
