It CAN'T move forward. It's not weightless. The conveyor belt keeps it from moving foward.

If it does move forward, the conveyor belt is failing to meet the speed.[/QB]
Not correct. The aircraft has weight, yet can still taxi around. It taxis by pushing air, not by turning its wheels. The conveyor cannot keep the plane from moving any more than an overhead conveyor (even with equal load-bearing, say, a weight of 500 lbs on a vessel weighing 500 lbs) can't keep a boat from moving.
