Link to Expeditions to the edge: Gemini 8 documentary
Documentary Description
Gemini 8 (officially Gemini VIII) was the sixth manned spaceflight in
NASA’s Gemini program. The mission conducted the first docking of two
spacecraft in orbit, but suffered the first critical in-space system
failure of a U.S. spacecraft which threatened the lives of the
astronauts and required immediate abort of the mission. The crew was
returned to earth safely. The only other time this happened was on the
flight of Apollo 13. This documentary reconstructs the events.
