Seperately, Amazon Chief Executive Officer Jeff Bezos unveiled a plan on CBS?s "60 Minutes" news program in the U.S., flying machines that can serve as delivery vehicles.
The gadgets, called octocopters, can carry as much as five pounds (2.3 kg) within a 10-mile radius of an Amazon fulfillment center. Amazon may start using the drones, which can make a delivery within 30 minutes, within five years pending Federal Aviation Administration approval, Bezos said.
The drones probably won't be put into use for four or five years, Bezos said.
Amazon has been trying to find ways to get products to consumers more quickly as it tries to keep shoppers coming back to buy from its Web store instead of going to brick-and-mortar retailers. The company said last month it was teaming up with the U.S. Postal Service to begin Sunday delivery to members of its $79-a-year Prime program.
