Visible crew/equipment: After Meelak opens the door to Rygel's quarters and asks Crichton why he wants the Hynerian's help, Rygel betrays Chrichton and says, "I don't think the mind cleansing is working," and when John punches Rygel's face, in the close-up we can see the puppeteer's fingers beside Rygel, behind the table.
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.
