It's already been three years since Amazon first revealed its somewhat audacious plan to make deliveries by drone. But the company is quite serious about this, and today it is announcing that it complete the first Amazon Prime Air drone-powered delivery. The company recently launched a trial in Cambridge, England -- and on December 7th, Amazon completed its first drone-powered delivery. It took 13 minutes from order to delivery, with the drone departing a custom-built fulfillment center nearby.

Amazon's video about the project says that it's only servicing a few customers in the area right now, but will soon be open to dozens more who live within a few miles of the Cambridge fulfillment center. Naturally, this center is custom-built to handle these types of orders -- once an order is placed and packaged up, the drone is loaded up and sent out from the facility on a motorized track. From takeoff, it flies at heights up to 400 feet to make the delivery and then return to the facility.
