Question about Shuttle Flight (spoilers)
Normally I'd leave this as a comment since it doesn't cite any official source, but it's answer-y enough and comments don't have spoiler tags.


   As you say, the plain text of the rules would seem to say this is allowed. And I think it does make sense RP-wise as well: "accessing" a haven basically means searching it (for tools, notes, inhabitants, etc), but in order to fly somewhere you just need to know where it is (it's on your map) and how to get there safely (you've charted a sea lane to it). The only problem RP-wise is if there's nowhere to land safely - you know havens have landing strips but you could argue it might be in sufficient disrepair that you can't use it, and that part of "accessing" a haven includes fixing up the strip.
