North Dakota will soon get a glimpse of a future where farmers can monitor their crops using small, flying drones. That's because the US Department of Transportation's Federal Aviation Administration (FAA) has given the state the go-ahead to start using its unmanned aerial systems (UAS) test site. It's the first one to become operation among the six commercial UAS testing program sites chosen by Congress in 2013. The state's Department of Commerce will hold two rounds of flight tests using Draganflyer X4ES drones not only to monitor crops, but also to test soil quality. These are relatively small, helicopter-like machines, which measure 36.25 inches in length and width and are equipped with Sony cameras.
