Once you have learned to fly your plane, it is far less fatiguing to fly than it is to drive a car. You don't have to watch every second for cats, dogs, children, lights, road signs, ladies with baby carriages and citizens who drive out in the middle of the block against the lights. . . . Nobody who has not been up in the sky on a glorious morning can possibly imagine the way a pilot feels in free heaven.
