Like clockwork April is the scene of the Frisian Flag exercise being held at Leeuwarden airbase. This years edition saw the participation of a large contigent of F-16 operators. Next to the Dutch F-16’s from Volkel and Leeuwarden, Poland was present and the U.S. Air National Guard sent eight Vipers from Duluth airport in Minnesota. A change of type as previous years the mighty Eagle was present at this exercise. Next to that France sent 4 Mirage 2000D’s, Germany a bunch of Eurofighters and Switzerland sent F/A-18’s although they left the exercise early so those were not observed when GVR Aviation was present.
