    Maybe they changed course to leave once they figured out where they were.
    There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.

    I wonder if there is anything interesting in where it is going--any exo-worlds in its path, say?
    I wonder, if Planet Nine happened to be in its path, could this alleged sail use it to slow down--in much the same way a sundiver solar sail might use Jupiter to "fall" back into the inner solar system?
