Amazon products are delivered via air (Video added)

Amazon.com Inc is testing delivery packages using drones, CEO Jeffrey P. Bezos said Sunday on the CBS television program "60 Minutes."

Jeffrey Bezos said the drones, unmanned vehicles that fly through the air, could deliver packages that weigh up to 2.3 kg. That represents roughly 86 per cent of packages that Amazon delivers, he said.

The drones, which would pick up items from Amazon's distribution centers and fly them to customer's homes, probably won't be put into use for four or five years, Jeffrey Bezos added.

A blog on Washington Post, which is owned by Bezos, said he showed CBS's Charlie Rose a working prototype of an eight-rotor helicopter drone called an "octocopter." Emblazoned with "Amazon Prime Air," the flying robot has a claw at the bottom that allows it to scoop up packages at Amazon fulfillment centers and carry them to customers' front lawns, the blog said.

The biggest hurdle is the fact that the US, or any other country for that matter, does not have regulations for so much crone occupying the air space. The company will also have to make drones that can carry the said load and stay in the air long enough to deliver the package and come back to base.
