I mean . . . there's literally skeletons in the ship; presumable the old crew. What with it being upside-down--not the typical orientation that results from a controlled landing--they probably all died and are now skeletons. I don't see the need to look much deeper than this.
Oh, apropos of nothing: one trivial (and I really mean trivial!) thing that did jump out at me was that the "Old Republic" credit had the Galactic Republic seal mostly seen in Clone Wars related media. So unless the old Old Republic used the same symbol (the one in the TCW Younglings arc may just be for the Jedi, even if it's the actual Republic seal in SWTOR where it originates) then the ship is no more than 1000 years old (give or take a decade.) My money is on it dating back to the High Republic era.
