Soyuz 5 (Russian: Союз 5, Union 5) was a Soyuz mission using the Soyuz 7K-OK spacecraft launched by the Soviet Union on 15 January 1969, which docked with Soyuz 4 in orbit. It was the first docking of two crewed spacecraft of any nation, and the first transfer of crew from one space vehicle to another of any nation, the only time a transfer was accomplished with a space walk – two months before the United States Apollo 9 mission performed the first internal crew transfer. The mission, flown by cosmonauts Boris Volynov, Aleksei Yeliseyev, and Yevgeny Khrunov, was also memorable for its dramatic re-entry. The craft's service module did not separate, so it entered the atmosphere nose-first, leaving Volynov hanging by his restraining straps. As the craft aerobraked, the atmosphere burned through the service module, allowing the remaining descent module to right itself before the escape hatch was burned through. During the descent, the parachute lines tangled and the landing rockets failed, resulting in a hard landing that broke Volynov's teeth.
