I don't see how the two are similar at all. When a baseball comes crashing through your window or hits you in the head the person who's responsible is most likely a few dozen feet away. Chances are it's a neighborhood kid who's easily identifiable. When a model airplane smashes into a car, person, building, etc. the owner could be thousands of feet (or miles as we see in this video) away. It's extremely difficult to trace the plane back to the owner.
