Plane or Drone?

Thanks to the magic of Google Maps, I was tootling around the Ten Thousand Islands just now, and noticed that right about here you can see a plane that was captured by the satellite cameras.

Or is it a drone? Drones have frequently been spotted in Florida, and some have been described as having no cockpit and looking like an upside down plane, which is a fair assessment of what we see on the Google maps.

On the other hand, it just might be an old biplane. Without being able to judge its size by gauging its distance, we may never know.
