COME, JOSEPHINE, IN MY FLYING MACHINE. It's the centennial of powered flight. The all-stars of test-piloting were on hand for a re-enactment that has been postponed account inclement weather. The story of the first flight includes a passing down of tradition and recollections by descendants of the witnesses, and the Nova story included the origin of a tradition. There had to be a first little boy to stick out his arms and run around making motor noises, and the show included a reminiscence by a man who might have observed that event.
