You can't gauge the airspeed of an airplane from the ground. What you are observing is the ground speed, which is affected by winds. So a small Cessna flying into a heavy headwind can appear to move very, very slowly relative to the ground.
I’m aware of that, and I tried to think that was what was happening. But the motion apart from speed was nothing like a typical plane, and the other factors led me to conclude it was a drone. When I say the FAA light patterns were off, what I mean is that it had two red lights on the outside, and two green lights on the inside. AFAIK, the only type of aircraft that might have that configuration is a trans-wing drone.

What? How do you get from a specific kind of lighting to „trans-wing drone“? What prevents me from lighting a regular-wing RC plane with the same lighting configuration?
