While there may always be unexplained phenomenon, it's hard to ascertain how long UAV/Quadcopter technology has existed. Perhaps the battery tech hasn't been here, but who's to say nuclear reactors aren't in play. People describe these things as big silent objects hovering. You have to wonder if nuclear engines haven't been a thing. To go from 'unidentified flying object' to sentience or some sort of being instead of just "some weird phenomenon" is the hardest point to make with people I talk to. It's frustrating.
