No, in fact it demonstrates just the opposite: A rotating frame of reference is not an inertial frame.
Well it so happens that if Pluto is stationary you will need to lead it by 102 degrees if you are shooting that missile from a rotating Earth. There is no difference between the inertial frames as far as the two observers in them are concerned.
Wrong again. If you play the animation in your link, you will note that the person on the merry-go-round does not lead her target, but throws the ball right at him the moment he appears in front of her. You will notice that at each moment during the animation, the ball's instantaneous velocity has it traveling towards the target, and this is true in both frames. However, the stationary target in the INERTIAL frame sees the ball travelling straight at constant velocity (because of the ball's INERTIA), while the rotating thrower sees the ball curve around and follow the target: She observes an ACCELERATION that cannot be accounted for by any real force. This is why the apparent force that would have to be acting on the object to cause the observed acceleration if the rotating frame were indeed inertial (acceleration which is not observed in an inertial frame) is called FICTITIOUS, and this demonstrates that rotating frames are not inertial.
You are correct that you would need to lead a target that is orbiting around you, but you are incorrect in saying that you would need to lead a stationary target if you are spinning. Rotational motion is not relative, and again, the link you provided shows how this can be demonstrated by experiment: The apparent curvature of the ball's trajectory shows the person on the merry-go-round that she is rotating, and since her target is stationary she does not have to lead it. If, on the other hand, she were not spinning and her target were orbiting around her, then she would have to lead the target, because being in an INERTIAL frame, she would see the ball going straight.
Great job, Zero Sum. Thanks!Said LeGrande:Replied Zero Sum:

What it is demonstrating is that there is no difference between being orbited or spinning. It is all about inertial frames of reference.
No, in fact it demonstrates just the opposite: A rotating frame of reference is not an inertial frame.[---snip---]
LOL Watch the animation again, you will notice that the sender releases the ball directly at the recipient in both cases. You will also notice that the recipient catches the ball directly behind the sender, 180 degrees away, in both frames of reference. Did you even watch the animation?
