As is often the case, the Reddit comments are the most amusing. But this one caught my eye:
If I’m reading it correctly, the comment in the middle is implying that there are ‘spotters’ (VO = Visual Operator?) at waypoints along the delivery route. Surely this is highly impractical and expensive? I suppose I’ll have to research how DroneUp operates.
And this moderator comment is excellent.
