I agree with patrical, It would be a novel idea to have the ground crew do a quick walk around prior to pushback. As an FE on a B-747 freighter I am required to do a walk around and lately I've been much more dilegent in inspecting the wheel wells for anything unusual but, the flight crew has no control once the doors are closed. Our employers may have to spend the extra nickle to the ground handlers to provide this extra service so , maybe that's why this service is not provided.
