WHEN Wilbur Wright flew around the Statue of Liberty in New York the other day, his doing it was a big event; but a still bigger event, as it seems to some of us, was the way he felt about New York when he did it. All New York could not make him show off. Hundreds of thousands of people on roofs could look up at the sky over New York for him to go by, all that they liked. He slipped down to Washington without saying anything, on the 3:25 train, to attend to flying as part of the serious business of the world.
