UPS researching delivery drones that could compete with Amazon's Prime Air - The Verge Amazon made headlines Sunday night when it announced it was working on small drones that could someday deliver customers packages in half an hour or less. But the e-commerce giant isn’t the only company researching how to harness the potential of small unmanned aircraft: The Verge has learned that the world's largest parcel service, UPS, has been experimenting with its own version of flying parcel carriers. Sources familiar with the company’s plans say it has been testing and evaluating different approaches to drone delivery. Asked for a comment, a company spokesman said that, "The commercial use of drones is an interesting technology and we’ll continue to evaluate it. UPS invests more in technology than any other company in the delivery business, and we’re always planning for the future."
