Maybe he's not so smart after all :)

On a calm day you can run and feel a wind on your face because you are
moving across the ground as well as through the air. But, if you run on a
treadmill there will be no wind because you are not moving through the air -
the air is calm so it has no relative motion with respect to the ground.
Neither do you when you run on a treadmill.


D*mn you're dumb. Oh sorry, was I thinking out loud? A thousand
pardons. :^)

The plane is NOT powered at the wheels! In this case the plane will be
going 60kts forward relative to the surrounding air and 120kts forward
relative to the treadmill. Think about it.
