Amazon isn't the only entity interested in using drones to deliver parcels. Swiss WorldCargo, the air cargo division of Swiss International Air Lines, is working with the Swiss Post and US-based transportation drone manufacturer Matternet to test the practicality of using drones in various stages of package transportation.

Specifically, the trio aim to clarify the legal framework, consider local conditions and explore the technical and business capabilities of drones through the use of a pilot program that'll take place this summer in Switzerland.

Matternet ONE drones will be used during testing. Built specifically for the transportation of small payloads, these aerial vehicles are capable of carrying up to 2.2 pounds of cargo a distance of more than 12 miles on a single battery charge. The ONE can fly autonomously along a set route generated by Matternet's proprietary cloud software.

Drones are expected to have a huge impact on a number of different industries. Whether it is ultimately in the field of internal logistics like moving stuff around inside a warehouse or the much more imaginative last mile delivery of physical goods, however, remains to be seen.

Because commercial use of the technology is such a new idea, the legality surrounding their use are still largely a gray area. Last month, Amazon was granted permission to begin testing in the US although extensive regulations forced the company to move operations to Canada.
