Musing over this a few days ago, I realized that in terms of angular dimensions in the horizontal plane, there was little to distinguish a flight of geese a mile away from some weird flying thangs a dozen miles away. So, I began to wonder by what easy method could a pilot distinguish the two. Then, eureka, it struck me. Any small vertical motion perpendicular to the common horizontal flight paths would readily tell the pilot whether the objects were very close to the plane or much nearer the mountains. Even a short motion of a foot or so such as bobbing the head up and down would cause nearby geese to wiggle more against the horizon than distant flying thangs. The veritcal motion of the plane during the turns would have made it painfully obvious. The apparent displacement of geese would be more than ten times greater than that of distant objects. This would be true of the formation of the objects even if individually they were moving up and down. Perhaps Arnold was so familiar with this way of distinguishing geese, he didn't feel the need to eliminate them early in his report. Bye... Ted..
