I was absolutely dazzled by the 1971 television movie Earth II - which was originally produced as the pilot for a series entitled The Olympians - when I first saw it as a little kid circa 1977. The titular space station was actually based on a real-world proposal by the late, great astronautical engineer Krafft Ehricke, who along with Buckminster Fuller also served as the film's technical advisor.

Yep - I loved Earth II when I saw it back in the day; and they were trying very hard to be technically accurate with regard to life on a near Earth orbit space station. Hell, their shuttle model was based of the original lifting body design for what would become the shuttle too. It would have made a good series (IMO).
