This series were my first contact with science fiction and after 30 years it's great to see them again. The series are repeated in Germany from time to time and it's a lot of laugh to see a flat-iron or a faucet, which are used as ship-controls. After the mission the crew met in the bar, which was deep underwater and you can see the fishes through the windows. IMHO there were two things, which made this mini-series successful. First, the crew-members were from different countries which was explained by their names (it was the time of the cold war). On the other side, there were extraterrestrial enemies, the "frogs", who wanted to slave the earth. And all the things were "sciene-fiction", they had video-phones (in a time where only a handful of people had a phone), they lived on the ground of the sea, they were flying with space-ships through the universe.
