Re: BVLOS?
'Surely "visual line of sight" is redundant, yes?'
In the context of controlling drones, the key part here is visual, which means that you can see the drone with your eyes. However, whilst you may have control Line-of-Sight to a drone, via its RC link, or in this case via 3G, you may not be able to see it with your eyes because it might be foggy, raining or snowing, or simply because it's night and too dark.
