©Byrd Antarctic Expedition SHADOWS OF TWO EXPEDITION PLANES PLAY LEAPFROG AS THEY RACE ACROSS THE ICE OFSCOTT LAND On this flight the Miss American Airways accompanied the Horlick as far as the Rockefeller Mountains, in the distance, made aerial motion pictures, and then headed for home. The other plane continued to the eastward and mapped the Edsel Ford Range, about 300 miles from Little America. To determine thecontours of unexplored areas, the aviators dived and skimmed close to the surface of the ice, reading the altimeters. Peaks could not be measuredinthis way, because aircurrents might suck the planes to destruction on the pinnacles if they flew too close.
