I see what you are saying. If the plane is exerting no thrust, in the scenario, the treadmill is also still.

I can see why this was such a connundrum. Even a few guys on that link someone posted disputed the conclusion.

Would it get to a point where the wheels cant spin any faster due to friction? Yet the treadmill would continue to increase speed to infiniti. That is where my brain starts to twist up. And if the wheels couldnt turn fast enough eventually it would counter the thrust of the engines through friction alone?

Im just asking questions, no need to get insulting.
