"EXPLORERS" is indeed correct! Here are the explanations...
1. First time it appears... Sisko's goatee first appears here. Also the first time we see a Bajoran solar ship, which we see next season.
2. You'd think it takes longer... Sisko built, by hinself, a solar ship. In episode time, it seems like weeks. One person, building a spaceship solo, THAT fast? Excellent episode from start to finish, but that was one thing that raised an eyebrow.
3. Only one difference... Sisko built the ship exactly as the Bajorans did theirs, except for the gravity generator.
4. Them? Really?... Dukat tells Sisko the Maquis may attack him as a ridiculous reason why not to do the trip. Sisko, of course, basically laughs at this.
5. Mistaken identity... Dr. Lense thought Bashir was an Andorian for all those years.
6. No middle... O'Brien tells Bashir he is not an in between guy. People either love or hate him.
7. A different sleeping arrangement... Hammocks are used in the solar ship, which is something rarely seen, if ever, in the franchise.
8. Sort of big... The ship has a lot of surface area, but very little mass.
Your turn, mlbach.
