The Swiss postal system, in collaboration with California-based drone delivery company Matternet, announced this week that they're testing a new package delivery service that uses drones as couriers. Switzerlands diverse terrain, full of mountains, lakes, rivers, and other environments easier to navigate by air, make it an ideal test site for flying robot mail delivery.

Drone delivery service has become a topic of intense interest among companies around the world in recent years, most notably Amazon in the U.S. The Swiss postal drone is, like many delivery drones before it, a quadcopter. Specifically, it's the Matternet ONE drone, which is specifically designed for cargo: no strapping on special hooks or adapting a camera copter to lifting here. Instead, Matternet ONE carries a box big enough to fit a couple apples in its hollow core. For delivery, the drone lands and then has the receiving customer open the box, which is probably wise but misses the midair theatrics of burger bombing.
