Hi Guinness,
I've asked some of the PC-9 crews about foreign visits this year, and not just about Leeuwarden, and they can't say yes or no to any visits yet, it's basically a case of wait and see.
It all depends on flying training schedules and availability. I don't know about the rest of the Air Corps fleet yet but I would say it will also be a case of wait and see.
Regards,
Frank.
