Last-mile food delivery service provider DoorDash has obtained federal authorization to operate as an air carrier and offer flying drone delivery service, the company said Wednesday. San Francisco-based DoorDash said it had secured Part 135 air carrier certification from the Federal Aviation Administration (FAA), a license which attests to an operator’s aircraft airworthiness, maintenance programs, and safety procedures. With that approval in hand, the company said it would launch an in-house drone program called DoorDash Air. “We want drone delivery to work for any merchant, anywhere. “Advances in hardware, compute, and AI are creating extraordinary new capabilities for local commerce, and becoming a certified air carrier accelerates everything we're building.”
