I was thinking more along the lines of making deliveries or scouting routes. I may have missed it in the article, but I don’t recall any mention of the size of the drones. Some drones are large enough to carry “packages;” hell, isn’t Amazon making deliveries via drone now, or Fed Ex, or UPS?
The full article at The Drive gives several estimates of size. Worth reading. I haven’t been to the comment section yet but those generally worthwhile as well.
