 Down on New York from the sky comes the plane that has circled the globe in under four days. Howard Hughes, stepping warily from the cabin, is surrounded by friends and overwhelmed by congratulations. To him, New York accords one of its triumphal rides. Seated in the back of an open car with sponsors of the World's Fair beside him, he drives slowly through the man-made canyons of Manhattan while paper streams from off his windows of lower Broadway. I just love those old newsreels.
