The Swiss Post might be one of the most advanced postal services in the world within a few years, if its plan to use delivery drones pans out. Here's one good sign for those who want to see that happen: it's slated to begin "testing the commercial use of logistics drones" sometime this month. We first heard about its intention to eventually use the machines for the delivery of small parcels back in April, when one of its program partners, California dronemaker Matternet, announced the project. As you'd expect, the agency will exclusively test several Matternet vehicles, specifically a model called "ONE." It's an autonomous quadcopter designed to follow pre-programmed flight paths and to carry payloads up to 2.2 pounds for over 10 miles in a single charge.
