In 34 years they have traveled about 15 light hours. It’s going to be a long flight to the next star at this rate.

Reminds me of a sci-fi story I read where a ship of colonists set off for a distant star, and since they didn't have FTL drives they had to be put in hibernation for the several hundred year journey.

When they arrived at their destination, they found it had been colonized centuries earlier by people from their own planet who developed FTL space flight and leapfroged their ship.
