This was going to be the trickiest part of the operation, and the most dangerous. Where before, Marsh had depended on automatic controls to guide him, now much of the responsibility was on his own judgment. He remembered the many hours he had sweated through to log his flying time. Now he could look back on that period in his training and thank his lucky stars for it. He took the manual controls and angled into the atmosphere. He carefully watched the AHF dial—the atmospheric heat friction gauge. When he had neared the dangerous incendiary point, with the ship having literally become red-hot, he soared into the frictionless vacuum again. He had to keep this up a long time in order to reduce his devastating speed. It was something of a shock to him to leave the black midnight of Earth’s slumbering side for the brilliant hemisphere where the people of Europe and Asia were going about their daytime tasks. He would have liked to study this other half of the world which he had glimpsed only a few times before in his supersonic test flights, but he knew this would have to wait for future flights. Finally, after a long time, his velocity was slowed enough so that the tug of gravity was stronger than the rocket’s ability to pull up out of the atmosphere. At this point, Marsh cut in “Harry’s” forward braking jets to check his falling speed. “There’s something else to worry about,” he thought to himself. “Will old Harry hold together or will he fly apart in the crushing atmosphere?” The directional radio signals from the powerful Skyharbor transmitter were growing stronger as Marsh neared the shores of California. He could see the winking lights of San Diego and Los Angeles, and farther inland the swinging thread that was the beacon at Skyharbor. All planes in his path of flight had been grounded for the past few hours because of the space flight. The only ground light scanning the skies was the gigantic space beacon in Phoenix. When Marsh reached Arizona, he began spiraling downward over the state to kill the rest of his altitude and air speed. Even now the plane was a hurtling supersonic metal sliver streaking through the night skies like a comet. He topped the snow-capped summits of the towering San Francisco Peaks on the drive southward, and he recognized the sprawling serpent of the Grand Canyon. Then he was in the lower desert regions of moon-splashed sand and cactus. Although the fire-hot temperature of the outer skin had subsided, there had been damage done to the walls and instruments, and possibly to other parts, too. Marsh was worried lest his outside controls might be too warped to give him a good touchdown, if indeed he could get down safely at all. A few thousand feet up, Marsh lowered his landing gear. Now the only problem left was to land himself and the valuable ship safely inside the narrow parallels of the airstrip. He circled the airport several times as his altitude continued to plummet.
