It won't lift and this is why: The thruster may be on to get the plane going, but the conveyor is creating a disruption in the planes actually ability to gain momentum down the runway. It would be like drying to drive on a frozen lake w/just the rims. Yeah they are going to spin hella fast but you won't get anywhere. Second there is no substantial airflow created to make lift and 3rd: unless the wings are postioned for lift off, the plane is staying grounded.
