It is not safe for spaceships to fly one after the other,
because their computers desynchronize, and their travellers
age differently. 

It is not safe to use a single looong spaceship, because
the front and the back like to accelerate differently and
... people who take seats in front age differently from
the people who are on the back.

No, you are not confused. You realized why those ufo-aliens
prefer flying rotating platforms to ordinary spaceships.
(Oh wait, there is that damnit Ehrenfest paradox, but they
have solved it.)
