And what is the significance of that? Star Trek has been *loaded* with strong female characters, from the obvious (Captain Janeway) to women filling just about every role you can think of that women are traditionally not supposed to have filled, from scientist to engineer to warrior to military commander, also including species overlords, the intellectual savant characters of a series, admirals, heads of state, the CO, the XO, etc etc etc... Saying "Well we FINALLY have a show where both the XO and CO of a ship are women!" seems like a prime example of an artificial benchmark to me. Seriously, you would have to dig deep to find a prominent role that women haven't filled in Star Trek, and that we even stoop to mention "Well, now they're filling the first AND second officer positions simultaneously!" shows how little this new show has to offer on the "breaking barriers" front.
