Soyuz 5

Soyuz 5 mission started with the launch on January 15, 1969, 07:04:57 UTC, carrying Commander Boris Volynov, Flight Engineer Vladislav Volkov and Research Engineer Pyotr Kolodin into orbit. Two days later mission achieved the first ever docking of two crewed spacecrafts, having Soyuz 5 docked with Soyuz 4 spacecraft. Since no connecting tunel had been developed yet, the two cosmonauts had to spacewalk from one vehicle to another. The mission concluded with a hard landing back on Earth on January 18, 1969, 07:59:12 UTC.
