This is not an aerospace engineering problem. An assumption is that the plane is already properly engineered. So we are back to Physics 101. Regardless, I wouldn't trust an aerospace engineer who has no grasp of basic physics (like the one you quoted).Please refer him to the physics professor quoted earlier.

It is disappointing that you have chosen to fanatically support the incorrect answer instead of taking a few minutes to understand this high-school level problem.
Yes, forces can cancel each other out and for the sake of our scenario, the thrust of the plane's engines is virtually cancelled out by the fact that the conveyor is matching any speed that can be generated by our plane's engines.

You are also looking at the situation from a Physics 101 viewpoint. You are not considering the principles of aerodynamics that are required for lift.

You also completely ignore the speed of the conveyor belt. Your argument is not even based on the hypothetical scenario. You made up your own scenario and are arguing based on your own scenario.

Until you can show or prove that there is enough air moving over this plane's wings, then you do not have the correct answer.

That is if there is even a correct answer. You certainly have not provided it. Arrogance IS NOT the correct answer.
