Since over five years I'm a global traveler and since 8 months I own a Mavic 2 pro. In my home country Switzerland there is no Licence needed to fly a drone. The only requirement is a liability Insurance. My question is if there is an international authority which issues pilot licences for drones. It can be very helpful, when dealing with authorities abroad, especially police officers, who sometimes are checking what you are doing. Thanks for any input.
