"I am dodging around to keep that big one from grabbing us with its magnet. Schwartzmann is aboard one of the patrols; they think the girl is in her ship. They won't fire on us as long as we hang on. But we'll crash if we do that, and they'll nail us if we let go." Harkness had placed the girl's body upon the floor. His answer was a quick leap to the pilot's side. "See to her," he ordered; "I'll take the ship. Stop us now? Like hell they will! What's all our power for?" One glance gave him the situation: the big gray fighter above, slipping down to seize them with her powerful magnets; four other patrol cruisers that slowly circled, their helicopters holding them even with the two ships that clung together in swift descent. Chet was right; no burst of speed could save them from the guns of the patrols if they dropped the red speedster and made a break for it. They thought Diane was still in her ship, and a patrol would have the little craft safe before she had dropped a thousand feet. Their own stern exhaust would be torn by a detonite shell, and the big cruiser would seize them in the same way. No--they must hang onto the girl's ship and outmaneuver the others. He pressed the metal ball forward to the limit of its space, and the stern exhaust crashed into action with all the suddenness of his own resolve. The ship beneath him threw itself straight ahead, flashed under the patrol-ship that blocked them, and was away. The weight below, and its resistance to the air, dragged them down, but Harkness brought the ball up, and the ship answered with a slow lift of the bow that aimed them straight out into space. A vertical climb!--and the voice from the instrument beside him was shouting orders to halt. On each side were patrol-ships that roared upward with him. "Cut those motors!" the voice commanded. "Release that ship! Halt, or we will fire!" * * * * * Harkness threw his ship into a wild spiral for reply, and the thin crack of guns came to him from outside. Down! A headlong dive! Then out and up again! He was through the repelling area in a twisting, rocking flight. Not hit as yet; they had to aim carefully to avoid damaging the red craft.... He was straining his eyes for a glimpse of serpent-forms, and he laughed softly under his breath at thought of his strange allies. Laughed!--until he saw them coming. He slammed down the switch on his own broadcast sender. "Back!" he shouted; "back, all of you! Look up! Look above you! The monsters are coming!--the air-beasts!--they are attacking!" He threw his own ship into a dive; saw the others do likewise; then leaped for the switch on the rescue magnets and pulled it open. He felt the red ship fall clear. He swung his own ship free and aimed it out and up on a long line of speed. Beside him a voice from a distant, fleeing patrol was shouting; "Come back, you fool! Down! Down, through the R. A.!"
