A lot of uses, did I hear right?
I can only imagine what plans have been made for other uses, can you?
On a personal note, I can imagine anyone could make an unmanned aircraft. There are plenty of hobby shops where pieces of equipment could be picked up to make such a device. Thought, a homemade device could be used to help secure your property (see what’s going on in the outskirts) and may help you bug out to your safe place.
