At last they were on the far side. In a moment they would be picking their way into the wreck. "Wilma, leap!" I almost whispered the order. The distance between Wilma's hiding place and the door in the side of the Han ship was not more than fifteen feet. She was already crouched with her feet braced against a metal beam. Taking the lift of that wonderful inertron belt into her calculation, she dove headforemost, like a green projectile, through the door. I followed in a split second, more clumsily, but no less speedily, bruising my shoulder painfully, as I ricocheted from the edge of the opening and brought up sliding against the unconscious girl; for she evidently had hit her head against the partition within the ship into which she had crashed. We had made some noise within the ship. Shuffling footsteps were approaching down a well lit gangway. "Any signs we have been observed?" I asked my men on the hillsides. "Not yet," I heard the Boss reply. "Ships overhead still standing. No beams have been broken out. Men on ground absorbed in wreck. Most of them have crawled into it out of sight." "Good," I said quickly. "Deering hit her head. Knocked out. One or more members of the crew approaching. We're not discovered yet. I'll take care of them. Stand a bit longer, but be ready." I think my last words must have been heard by the man who was approaching, for he stopped suddenly. I crouched at the far side of the compartment, motionless. I would not draw my sword if there were only one of them. He would be a weakling, I figured, and I should easily overcome him with my bare hands. Apparently reassured at the absence of any further sound, a man came around a sort of bulkhead--and I leaped. I swung my legs up in front of me as I did so, catching him full in the stomach and knocked him cold. I ran forward along the keel gangway, searching for the control room. I found it well up in the nose of the ship. And it was deserted. What could I do to jam the controls of the ships that would not register on the recording instruments of the other ships? I gazed at the mass of controls. Levers and wheels galore. In the center of the compartment, on a massively braced universal joint mounting, was what I took for the repellor generator. A dial on it glowed and a faint hum came from within its shielding metallic case. But I had no time to study it. Above all else, I was afraid that some automatic telephone apparatus existed in the room, through which I might be heard on the other ships. The risk of trying to jam the controls was too great. I abandoned the idea and withdrew softly. I would have to take a chance that there was no other member of the crew aboard. I ran back to the entrance compartment. Wilma still lay where she had slumped down. I heard the voices of the Hans approaching. It was time to act. The next few seconds would tell whether the ships in the air would try or be able to melt us into nothingness. I spoke.
