My blog goes into the story behind this custom MOC.  Essentially, however, I had done a number of posts about  LEGO's Classic Space era.  While watching, with my sons, some YouTube videos showcasing the various subthemes from the era, they commented on the original Space Police subtheme from 1989 and told me I should build a spaceship inspired by that theme.  Well, with the gauntlet thrown down and needing little excuse to build a Space themed project, I embarked on that endeavor.  This is the result.  Check out my YouTube video on this one as well.
