Summarize the article about the use of drones for delivery.
Drone startup Wingcopter, working with partners Merck and the Frankfurt University of Applied Science, has completed a first flight of a new drone delivery trial designed to show the benefits of using drones instead of trucks or other road-faring vehicles for moving small cargo between two physically separate office facilities. This first flight covered around 25 km (roughly 15.5 miles), taking a sample of pigments from one Merck lab in Gernsheim to its headquarters in Darmstadt in Germany.

This trial is significant in more ways than one: The area it covered spanned a fairly dense metropolitan area, flying over power lines, trains, roadways and more. It also did all of this without continuous line-of-sight, something that’s been required of most drone delivery trials in a commercial setting to date. The partners involved are hoping this means it can stand as a blueprint to other similar pilot projects and trials being run all over the world.

Next up, the project will continue to fly additional deliveries and then summarize their findings in a report to be delivered in March. Already, using drones instead of trucks seems to provide advantages in terms of time (saving between an hour and even a full day in some cases) and emissions, and it can cut down on the amount of empty return trips made by large, heavy gas-guzzling vehicles, as well.

The flight covered a dense metropolitan area without continuous line-of-sight. The trial demonstrated the benefits of using drones instead of trucks for small cargo, saving time and reducing emissions. The successful flight could serve as a blueprint for other similar pilot projects, and the partners plan to release a report summarizing their findings in March.
