well, the Nostromo was from Alien, and they got hunted and subsumed/eaten . . . Argos and Galliott where from the vampire planet or something (I have very fond memories of that from when I was a kid on a Saturday afternoon), where they crash and dead bodies get possessed -- not sure how they are related. . . and although I know what Icarus and Bellerophon are from mythologically speaking, I don't know how they tie in here . . . more ships in the Alien sequels?
