MATT WAITE: "Drone journalism as an idea is less than a year old at this point. The first instance I saw was a labor protest in Poland where a man had a remote-controlled helicopter and he put a camera on it and he flew it up and got just a view of the protests from the air. And you could see police moving into position to kind of block the protest route."
怀特：“目前，‘无人机新闻’作为一种理念诞生尚不足一年。我看到的第一个实例是在波兰的劳工示威中，一名男子使用一架安装了摄像头的遥控直升机飞上天空，从空中拍到了示威的情景。你可以看到警察移动到位堵塞示威路线。”
