Vault 22 Survivor
I just realized. It's entirely they go to space, due to very little changes of the navigational flight plan during the quest. This means that it will probably go the original planned route into space.
Jason Bright & co. could have already programmed their coordinates while they were hanging around in the REPCONN building since presumably they knew where they were going long before they were capable of getting there, you just can make an alteration to the course so they get closer to their intended target.
As an aside, considering the topic of the thread, does anybody else think that the notion of "you can do stuff after the ending" to be kind of intrinsically weird? Like it's fine if you want to tell other stories set after the end of the game in add-on content (e.g. Throne of Bhaal after BG2), but it seems bizarre to expect the story to contain more things after the story has finished. Like if there's more the writers want to get in there, they could just put it before the ending.
