I'm looking into making AIShips recognize "flightplans", but I haven't
worked on this area of the code for a year or 2, so initial progress is
likely to be slow while I refresh my understanding.
Meanwhile, the low, slow hack certainly works - Dene uses it with great
success. I think you have an error in your FP - the last entry should be:
<wpt>
<name>EOF</name>
</wpt>
see tanker_racetrack.xml for an example
