One way for me to rationalize the possibility of some UFOs being alien tech is the possibility that they are drones — unmanned. Popular culture consideration of UFOs as alien craft seem to assume there are sentient beings inside, possibly due to the history of reported abduction experiences with little green or grey beings. But arguments against alien craft that question why they move so quickly with abrupt unnecessary direction changes, and lack of interaction with humans, to me could be explained by imagining that they are “unmanned” craft. No need for “inertial dampers” or other tech to deal with the hyper fast direction changes if there’s no beings inside.
