Amazon has been given the go-ahead by US regulators to begin testing drones that it hopes will soon be delivering packages and products to customers across the country.
The US Federal Aviation Administration (FAA) has confirmed that Amazon can test fly its unmanned aircraft but only with licensed pilots behind the controls.
Existing US laws prohibit the flying of unmanned drones for commercial purposes but Amazon is apparently expecting to see the relevant rules relaxed following FAA revisions.
For now Amazon's drones will only be flown during daylight hours, no higher than 400 feet above the ground and within sight of their pilot.
To date Amazon has been focusing its drone testing on locations outside the US but has made no secret of its desire to trial drone-based delivery services in its home country.
"Without approval of our testing in the United States, we will be forced to continue expanding our Prime Air R&D footprint abroad," Paul Misener, Amazon's vice president of global public policy wrote in a letter to the FAA in December last year.
