Amazon has made its first commercial delivery using a drone, in the UK.
The package arrived safely at its destination in Cambridge, 13 minutes after being ordered.
A video showing the process details how the order was completed using an electrically powered drone flying at up to 400ft.
As part of the testing for the Amazon Air service, the delivery took place on 7 December, although it was only revealed on 14 December.
The Cambridge fulfilment centre is home to the drones, which, once the ordered package is on board, travel along an automated track to the launch area.
The drones then take off and fly completely autonomously, guided by GPS to their destination.
They are capable of carrying items weighing up to 2.7kg (5lbs).
The aim is that all orders made using Amazon Air will be delivered within 30 minutes.
The trial will be expanded to dozens of customers living close to the warehouse in the coming months.
The safety of drones has come under the spotlight in recent months.
There have been reports of near-misses this year between drones and aircraft at London Stansted and Cornwall Airport Newquay.
“Safety is our top priority,” Amazon said on its website. “We are currently permitted to operate during daylight hours when there are low winds and good visibility, but not in rain, snow or icy conditions.”
There are Prime Air development centres in the US, UK, Austria and Israel. The company is also testing its drone vehicles in “multiple international locations”.
The real significance here is the impact it has on shopper expectations. Last year, same day delivery was considered impressive; now it’s all about 13 minute lead times.
Fulfilment has become a firm battleground in retail and the most successful retailers today are those who can deliver products to shoppers in the quickest, most convenient and economical way.
