Perhaps even better, a wind-powered car can travel faster than the wind downwind! link
This seems to imply that you have some other mechanism for the plane to take off than by harnessing that very mechanism with enough efficiency and elegance that it can generate lift to take off engine free, powered by wind, with the direct force of the wind actually counting against it. Either that or you evaluate engineering coolness very differently.
