Soyuz 4/5

So basically, after a rendezvous in earth orbit as a training mission for a potential moon mission:

- Soyuz 5's service module failed to detach at retrofire, twisting the vehicle and leaving the heat shield pointed the wrong way as it re-entered the atmosphere. The interior filled with noxious fumes as the gaskets sealing the hatch started to burn. Eventually, the stress and heat being generated outside the spacecraft caused the connecting struts on the service module to finally give way and flip the heat shield the right way.
- In the chaos of re-entry, some of Soyuz 5's parachute cables fouled, resulting in only a partial chute deployment. Just to ice the cake a bit, the soft-landing rockets failed, too, so Volynov was very aware of impact when his hardy Soyuz module plowed into the earth. It hit the ground so hard, in fact, that Volynov broke his teeth.
- he landed in the Ural Mountains, where he was greeted by a local temperature measuring a brisk minus 36 degrees Fahrenheit With rescue several hours away at best, our intrepid cosmonaut decided to hoof it for safety. He plodded a few kilometers before finding a cheery fire and a brimming samovar in the cottage of a welcoming peasant.

Amazing!
