Between 11 and the 22th of april 2016 a large exercise was held at Leeuwarden Air Base in the Netherlands. The exercise is called Frisian Flag 2016. Participating aircraft from several countries in the world will be airborne twice a day. The purpose of Frisian Flag is preparing for any conflict, the main reason is cooperation between the multiple countries. Every other nation speaks another language and is it important that everyone will speak the same during conflict situations.
