One of the might-have-beens: Greg Jein went to the trouble of casting a custom saucer for this one (and for the three-nacelled Niagara) to create a model that with a little more work could have been a proper, lit and motion-controlled photographic model for close-ups.
Today, it's so much easier to whip up "kitbashes" that are actually made of 100% custom-built elements and merely tip their saucers to the "general spirit" or "design ethos" of the hero ship of the day instead of directly recycling her parts... But Jein's single-naceller is a worthy stablemate for the TNG hero vessel, and a sad reminder that the E-D never really got an entourage of fitting designs to accompany her. The only two designs sharing the "design ethos" thing and actually having screen time were the Nebula and the Akira; a number of smaller or more distinct companions would have done the show good, and allowed the franchise to save the TOS movie designs for creating the proper "era feel" for other spinoffs.
