I’m finding myself starting to think about the Antares from “Charlie X.” In the episode the two Antares crewmen we saw were wearing older “The Cage” era style uniforms. Maybe the Antares was low in priority in having new uniforms issued to them? Or they had been out in the boonies for a long time and haven’t yet gotten back to base where they could have arranged for new uniforms? If we accept WNMHGB happened pre 5yr. mission then the Starfleet uniform change is relatively recent. In the episode was the Antares referred to alternatively as a survey vessel and a merchant vessel? I don’t recall off the top of my head. I do recall the James Blish adaptation describing the ship as quite a small craft compared to the Enterprise. It goes without saying I’m not swayed by the retconning of a version of the robot freighter from TAS as the Antares. The time is 1966 and early in TOS’ production as a series. The first episodes haven’t even been aired yet. Gotta figure out what Matt Jefferies and/or Wah Chang could be thinking if tasked with whipping something up for a scant few seconds onscreen. Unlike “The Cage” and “Where No Man Has Gone Before” where the referenced ships were vessels lost many years earlier, this is a case where the ship referenced is in the here-and-now and supposedly holding station right next to the Enterprise. We should have seen it.
