Please answer the following questions:

1) How is an airplane's speed measured?

a. Groundspeed
b. Airspeed
c. Other (specify)
The hypothetical scenario does not specify the type of speed. Hence, a large reason the scenario is a conundrum.[/b]
In the event something is not specified, a logical assumption should be made. Speed means speed and is not dictated by wheelspin, it is dictated by movement with respect to the earth's surface. I have listed two methods of measurement that make sense.
So far, nobody has been able to explain why they think Isaac Newton was wrong and the plane can't move.

All I hear is people going back and forth over sidenotes instead of coming to terms with the physical realities here.

There is only one correct answer to the problem. I recommend trying to understand the simple solution instead of wandering around in a fog of superstition.
