This is the deal...I will go out and buy a model plane...most likely a cheap one powered by rubber bands....just to prove this to you. A rubber band powered plane can do this...I will put the plane on the belt and hold it there while you set the belt to it's highest speed...when I let go of the plane and release the rubber band...it will fly, but I am not going to all that trouble if it isn't worth my while.
