This vessel is, according to me, the closest that a vessel could look for long-term journeys into space. This 1968 movie was really innovative (I had three years old at this time).
Before I made my current attempt to build the Discovery I realized that I really wanted to finish it this time. So yeah, no need to rush, small mistakes are ok and the repetitive work on the spine is a very good deal for an impressive model at the end I think
