Like a random feather, a sailplane, one of its wings hidden, loops slowly above the pleasant geometry of English countryside. Although sailplanes have no motor they can perform almost any aerobatic feat. To loop, the flyer holds his craft in a dive until a velocity of some 70 mph is attained. Then he eases the stick back and goes up, over and out to the sweet, resonant note of the wind.
