Trivia: In at least series one, the ships "throttle" control for the non-pilot crew is a painted Logitech Trackball.
The Hidden Memory (2) - S1-E20
Trivia: While John's in the Aurora Chair, with the images on its screen showing the fake memories that Gilina manipulated, John comments that it "Kinda looks like an episode of Melrose Place." Ben Browder had guested on Melrose Place prior to Farscape.
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.
