"I'll overtake him going west. If I went the other way I'd meet him going at over 10 miles a second in relation to his machine. He had the right idea. He told me to fall out to him at a greater than orbital speed. I will go just within the Earth's atmosphere till I get just under him, holding myself in the air by means of a downward acceleration on the part of the regular lifting power units. I am going to try to reach eight miles a second. We will be overhauling him at three a second, and the ship will slow down to the right speed while falling out to him. We must reach him before he gets into the shadow of the Earth, though, for if he reaches 'night' he will be without heat, and he'll die of cold. I think we can reach him, Dick!" "I hope so. Those spare cells are all right, aren't they? We'll need them! If they don't function when we get out there, we'll fall clear off into space! At eight miles a second, we would leave Earth forever!" The ship was accelerating steadily at the highest value the men aboard could stand. The needle of the speedometer crept steadily across the dial. They were flying at a height of forty miles that they might have enough air and still not be too greatly hindered by air resistance. The black sky above them was spotted with points of glowing light, the blazing stars of space. But as they flew along, the sensation of weight was lost; they had reached orbital speed, and as the car steadily increased its velocity, there came a strange sensation! The Earth loomed gigantic above them! Below them shone the sun! The direction of up and down was changed by the terrific speed! The needle of the speedometer was wavering at 7.8 miles a second. Now it held steady! "I thought you were going to take it up to eight miles a second, Dick?" "Air resistance is too great! I'll have to go higher!" At a height of fifty miles they continued at 8.1 miles a second. It seemed hours before they reached the spot where the pirate's machine should be flying directly above them, and they searched the black sky for some sign of the shining dot of light. With the aid of field glasses they found it, far ahead, and nearly one hundred miles above. "Well, here we go! I'm going to fall up the hundred miles or so, till we're right in his path; the work done against gravity will slow us down a little, so I'll have to use the power units somewhat. Did you notice what I did to them?" "Yes, they're painted a dull black. What's the idea?" "We'll have no air from which to get heat for power out here, so we'll have to depend on the sunlight they can absorb. I'm using it now to slow us down as much as possible."
