I've been watching several episodes on Netflix and recently finished watching this episode. In it, there's a line that says "Starfleet has dispatched two vessels to meet with Voyager, scheduled for five or six years' time." However, at this point, Voyager is at least 30,000 light years from home at maximum warp. How does Starfleet have vessels capable of going that distance in less than 6 years? Is this why the Enterprise E is capable of flying from the Neutral Zone to Earth so quickly in First Contact?
