In the weekend of June 24@25 2017 there will be an airshow at Rhoon, above the river Oude Maas. Currently their website is still under construction but they have a Facebook page: https://www.facebook.com/AirshowRhoonRotterdam/
Participants are not mentioned yet, but images show:
-Swiss F-18
-BAF F-16 demo
-RNLAF Apache demo
-OV-10 Bronco demo
-KLuHV B-25
-KLuHV Spitfire
-PBY Catalina
