SAN FRANCISCO: Amazon on Monday said a freshly-issued Federal Aviation Administration certificate has cleared the launch pad for drone deliveries in the US.

The Seattle-based e-commerce colossus has been developing drones as part of its massive investment in a logistics network to quickly deliver purchases to customers.

"This certification is an important step forward for Prime Air and indicates the FAA's confidence in Amazon's operating and safety procedures for an autonomous drone delivery service that will one day deliver packages to our customers around the world," Amazon vice president David Carbon said in reply to an AFP inquiry.

"We will continue to develop and refine our technology to fully integrate delivery drones into the airspace, and work closely with the FAA and other regulators around the world to realize our vision of 30 minute delivery."
