Think of an airplane as two independant entities:

The airframe, and the rolling gear.

Any and all forces generated by a conveyor in an attempt to affect the perceived forward progress of the airframe will instead be enacted upon the rolling gear only.

The force the conveyor is trying to enact upon the airframe is lost due to the free-flowing wheels. The force is dissipated through the wheels, and never reaches the airframe.

The airframe, in essence, does not know what the conveyor belt is trying to do, and doesn't care.
I've been trying to get this point across, but the "CF" people can't seem to grasp it.

The conveyor belt exerts ALL of it's force on the wheels, NOT the engines. The only thing exerting a horizontal force on the engines is the air. Therefore, the conveyor will have 0 effect on the engines thus causing the engines to pull the airplane forward while the wheels spin at an unGodly rate of speed. This forward momentum will eventually give the airplane the needed lift to be able to take off.
