I never understood this discrepency between STAR WARS fantasy and STAR TREK's supposed adherence to scientific truth. STAR TREK relies quite heavily upon fantasy, and always has. Only it has tried to curb it to not make it so apparent and this has never been to advantage. Take VOYAGER's Kes, for example. Obviously designed after Fairies, Elves and other mythical creatures, and yet ... NO butterfly wings! She really needed the wings, BUT............that's taking it "too far" into the Fantasy Realm, apparently. So, they invested the character with a lifespan roughly that of a Virginia Oppossum. What's more, they gave her these unexplained, almost Q-like powers originating out of nowhere -- just to keep her in the realm of scientific probability. STAR TREK and STAR WARS probably should try a cross-over, maybe start that in the "official" comics, if they haven't already. Having R2-D2 flushed out into space has to be the beginning of something for STAR TREK ...
