Visible crew/equipment: In the bottom left hand corner of the screen during the overhead shots of the celebration fire, you can see a camera, with white film canisters on a lower boom. (00:37:00 - 00:38:00)
Visible crew/equipment: After the pod has landed on the planet, when D'Argo and Rygel experience power loss, the hoverchair looses power and Rygel's thrown into the dirt. Then as Rygel shouts, "D'Argo? Where are you going?" the head of the puppeteer, who's wearing a knit cap, can be seen at the right side of the screen.
Continuity mistake: When Lishala gives John the map of the sky she asks him where his home world is, and John picks up a very small stone, but in the closeup he's holding a much larger stone in his hand, then in the wide shot it's small again before he throws it.
Chosen answer: It's never explained. John mentions a theory that his less technologically developed craft simply interferes with the wormhole less than the "superior" Vipers, but they never make a concrete determination on that point. But we also have to take into account the fact that Moya traverses wormholes with no ill effect as well.
