I suppose there's another point. The OP doesn't mention the issue of the wind speed. If a gale was blowing hard enough then the plane would get enough lift to take off and could turn around and fly off.
There's another way to look at this. Maybe the OP means that the wheels on the conveyor move at the same speed - angular velocity - as the plane's wheels. But one or the other may be bigger so would move further. If the plane's wheels were a bigger diameter then for each revolution they would move further and the plane would accelerate and take off. If it was the other way around the plane would go backwards and crash into the control tower.
