You keep saying flying high. What alitude are you talking about. Maybe you are flying so high lack of oxygen is clouding the facts. Just kidding... I don't like the long grind getting up there (whereever that is). I enjoy seeing the ground from a closer perspective. If I want to see little towns and roads and cars I'll fly the airlines..
