Look at the Princess (3): The Maltese Crichton - S2-E13
Visible crew/equipment: While Tyno, Chiana, D'Argo, and Rygel are in the senate chamber with the headless statue of John, when Empress Novia shouts, "whether they purport to be a friend of the crown or not!" we can see Rygel's greyish haired puppeteer, who is hiding behind Rygel, move as Empress Novia walks by.
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.
