This is interesting, but seems a little outdated tech-wise. Have you ever heard the stories about glimmer man? There is a podcast called expanded perspectives that has relayed more than a few handfuls of stories about glimmer man (specifically the tech related to the digital camouflage subject, that projects in front, what is behind)
Not drone related, but...
The specific story I am referring to talks about a couple who were driving through back roads and stumble upon a scenic view in an out of the way area, and when they looked at the view got a sense that it was a digital screen, then the 'father' walked into the woods to relieve himself and notice a figure moving, the shape of a man in full gear, almost totally camouflaged, sort of digital, but moved like an army soldier. 

Sort of reminds me of the same kind of tech may be it is related.

It reminds me of that accounting of the hunter who went stalking a deer or something, he shot it, the deer ran and stumbled and he ran after it a close distance. He was expecting to see the deer collapsed and bleeding because he was experienced and knew a clean hit, but the deer was simply gone, not even blood or anything. He kept walking slowly and carefully, expecting at any moment to see anything at all, but there was nothing, no sound or anything at all, as if the deer simply vanished. Remember he was an old and experienced hunter, he couldn't have lost his deer just like that.
Anyway, suddenly he noticed that the forest was odd in a way, as if painted or artificial. Like you see the forest on a high definition TV vs what you see in real life with your own eyes. And as we walked further, he looked down to see his own footing, and saw that his legs disappeared, as if they were covered under an invisibility blanket or something strange like that.
