无人驾驶飞机在天空翱翔

2013年，当亚马逊首次提出使用无人机投递包裹时，就引发了一场风暴。谷歌在2014年透露，它一直在研究一个秘密的无人机交付项目，而美国宇航局在2015年宣布，它正在研究一种基于云的无人机系统(UAS)交通管理系统。

与此同时，企业家们开始将无人机作为一种服务提供给公司，租用无人机进行航拍或拍摄视频，用于测绘和其他服务。

据约书亚·齐林(Joshua Ziering)在报道无人机行业的《商业无人机新闻》(Commercial UAV News)上的一篇文章称，到2018年，无人机作为服务行业陷入了困境。

根据美国联邦航空管理局(Federal Aviation Administration，简称faa)的“小型无人机”规则(Part 107)，想要成为无人机驾驶员的人只需要参加两个小时的考试就能获得驾照。

齐林写道，与此同时，那些将无人机业务外包给服务提供商的大公司也在创建自己的小型无人机初创公司。

快进到2020年，无人机现在普遍用于空中摄影和摄像，覆盖现场事件，运送小型物品，以及调查危险的地方和情况。

原文：When Amazon first proposed using drones to deliver packages back in 2013, it kicked off a firestorm. Google in 2014 disclosed it had been working on a secret drone delivery project, and NASA in 2015 announced it was working on a cloud-based unmanned aircraft systems (UAS) traffic management system.

Meanwhile, entrepreneurs began offering drones as a service by renting drones to companies to do aerial photography or shoot videos, for surveying and mapping, and other services.

By 2018 the Drone-as-a-Service industry was in trouble, according to a piece by Joshua Ziering in Commercial UAV News, which covers the drone industry.

Hardware quality had improved while would-be drone pilots only were only required to take a two-hour exam to get their license under the U.S. Federal Aviation Administration's Small UAS Rule (Part 107).

At the same time, large companies that had outsourced drone operations to service providers were creating their own little drone startups in-house, Ziering wrote.

Fast-forward to 2020 and drones are now commonly used for aerial photography and videography, to cover live events, deliver small items, and to survey dangerous places and situations.
