What happens if the wind stops blowing?
Nothing happens to the glider. It doesn’t need wind to fly. Gliders are not kites. All a glider needs to fly is air flowing over its wings. It’s the pull of gravity that keeps the air flowing over the wings. As a glider flies, it is gently coasting downhill. Coasting downhill, the glider feels the winds, just as a bicyclist feels the wind while coasting downhill. Of course, if the glider flies through rising air, it climbs. Fortunately, air and gravity are not in short supply.
