Soyuz 25
1977-099A
7K-T (11F615A8) No. 42 was launched on 1977 Oct 9 as Soyuz-25. Crewmembers Vladimir Kovalyonok and Valeriy Ryumin were meant to be the first long stay expedition to DOS 5 (Salyut-6) but the docking was a failure. At only 1 m range, on final manual approach, the crew aborted the approach when they erroneously thought the approach angle was incorrect.
