“UFO” or a “spacecraft” ... I still say it’s a child’s toy controlled by a remote control. Silly attempt to look like a “UFO” or am alien “spacecraft”.
That somebody local built it, I'll agree with. That it's remotely controlled, sure. That it's a child's toy? Something of a stretch. If it is a toy, I've never seen one of these for sale at FAO Schwartz.
And I'm not seeing a propeller on it, either. I wonder how it's staying up there...
