The Hidden Memory (2) - S1-E20
Visible crew/equipment: After Pilot (on viewer) tells Rygel and Chiana, "Moya's data stores indicate it may be best to get the offspring out as fast as possible," when it cuts to Rygel's close-ups we can see the blonde head of the puppeteer at the lower left side of the screen.
The Hidden Memory (2) - S1-E20
Visible crew/equipment: After the shot of Gilina, Aeryn, and John crouching under a floor grate, while hiding from the PKs, it cuts back to Moya, and just as Chiana reaches Rygel we can see the base of his hoverchair.
Visible crew/equipment: After Aeryn activates the cannon on the Leviathan baby's exterior, when Aeryn says, "Pilot...please let me know if any Peacekeeper scans are imminent," as she walks away the camera follows her, and we can see a nice reflection of the cameraman/crew member at the right side of the screen. The reflection's briefly visible again when Chiana says, "The only weapon we've got is that kid."
Family Ties - S1-E22
Visible crew/equipment: After Rygel's transport pod returns to Moya, as the docking bay door slides open, in the shot facing everyone while they have their weapons drawn we can see the bare floor. However, when Aeryn checks Crais for hidden weapons and then as D'Argo approaches him, there's a blue crash mat on the floor. Then it vanishes again.
Family Ties - S1-E22
Visible crew/equipment: After the transport pod successfully ignites the moon, D'Argo and John are floating in space while Aeryn's in her Prowler, and just as we hear Pilot start to say, "The offspring Leviathan, Talyn, has broken from Moya's side," we can see the face of Rygel's puppeteer under the table, at the bottom right of the screen.
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.
