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."

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.

Trivia: In at least series one, the ships "throttle" control for the non-pilot crew is a painted Logitech Trackball.

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.
