But we are talking about airplanes running over gliders. That will
most likely be a non headon situation, and in that case the airplane
shall avoid the glider. Of course, that's just like saying the
pedestrian has right of way in a crosswalk - some dopes think that
stepping out in front of a car will somehow magically make 1) the
driver notice them, 2) allow the driver to stop in time.
