Soyuz 7

Soyuz 7 carried Anatoly Filipchenko, Vladislav Volkov, and Viktor Gorbatko during the October 1969 three-spacecraft Soyuz 6 / Soyuz 7 / Soyuz 8 operation. Spacefacts lists launch from Baikonur Site 1 on October 12 and landing northwest of Karaganda on October 17 after 4 days, 22 hours, 40 minutes, and 23 seconds in orbit. The spacecraft was intended to take part in a docking sequence with Soyuz 8 while Soyuz 6 observed nearby. The rendezvous electronics did not support the planned docking, and subsequent attempts were not completed, leaving the mission as a coordinated group-flight and systems-test operation rather than a successful docked transfer mission. The flight nonetheless placed Filipchenko, Volkov, and Gorbatko inside the first seven-person, three-spacecraft human orbital operation.
