Drones（无人机）are like planes, but come in many shapes and sizes. They have no pilots and controlled from outside the drones. During these years, they have been used to attack（进攻）enemies or moved goods in dangerous areas.
Now small drones are a part of people's lives. For example, people use drones to take photos or make videos. Besides, a drone delivery (投递) service has proved successful.
Online store JD can use drones to deliver small packages（包裹）. It has built several drone stations so that it can load(装载) and deliver its packages.
Drones have made our shopping experience different. We can order a new coat in early morning and it will be delivered before we finish breakfast.
Bizzby Sky, a UK company, has created a delivery service for small goods. Open a smartphone app(应用软件), enter your address, set a time and pay enough money for the delivery service. Then in minutes, a drone will do tasks for you.
However, any drone company needs government permission (允许) to fly its drones in many countries. We believe we will see more and more drones with goods fly in the sky very soon.
