Plane on conveyor... Will it ever take off?

[HRCNICK11]

Turbines pull air over the wings which aids in lift. How much I don't know.

I'm sure if you reached the 175mph and stopped the engines the plane wouldn't lift. You would have to increase speed. But yes air moving across the wings is the only thing lifting the plane, but we are discussing how that air gets moving.

The part your missing is the belt would not be able to hold the plane in place because the plane moves through air no matter what the wheels are doing.
