The Swiss Post decided not to miss out on potential opportunities and began testing drones to deliver certain packages by air. The duties of the air postman are assigned to a drone called One, which is designed to transport small loads weighing up to 1 kg. The device is able to cover a distance of about 10 km from a single charge. The flight of the drone will be controlled by “cloud” software, which will pave the way along a predetermined and most secure path. This type of delivery is used in exceptional cases and only for transportation of special items, for example, urgent laboratory tests or small loads to areas of natural disasters.
