Heres a question about the ID as well.
It says I am allowed to fly Liners, this includes the Bretonian royal Liner. Would it be proper to have say an FL IFF and a researcher ID?
And if so, would it be OK to enter Kusari?
Kusari laws don't forbid Bretonian ships in their space.
However Naval Forces and Police officers will probably ask for an explanation.
And for the IFF, I recommend to use none. That way people will scan you and see you are actually a researcher, instead of keeping calling you "Freelancer" just because that's what they see.
