"Hmm..." Bill thought for a moment. "Twenty-eight point one light-years. The cargo carriers aren’t capable of more than five G, and they wouldn’t be here yet if they’d been pulling much less. So I expect they went for minimum travel time instead of trying to extend their personal time during the trip. That puts it just a shade under two years subjective." He looked around the group. "That’s a lot of time, but I think if they had loaded the cargo vessels to capacity, they’d have extended the trip. Thor, can you work with that?"
