<passage>:
I heard the voice as I opened my eyes. I was lying down, still not I shouted a protest against the strangeness of the room. I looked to twisted my head to look for the button. I pushed away from the close body, found the wide strap that held me and fumbled with the buckle. I threw it off and pushed myself up from the hard cot. I heard myself yell in surprise as I floated up towards the light overhead. I was weightless. How do you describe being weightless when you are born into a world bound by gravity. I twisted and shut my eyes in terror. There was no sensation of place, no feeling of up or down, no direction. My back When I reached the cot I held it and drew myself down. I glanced at the that appeared to be air tight. I stared at my familiar hands. I rubbed them across my face, feeling the solidity of flesh and bone, afraid to think too hard about myself. "My name ... my name is...." nothing to me, but I thought about it, watching the relentless lights that shone below the dials. I stood up slowly and looked at myself. I was naked except for heavy shorts, and there was no clue to my name in the pockets. The room was warm and the air I had been breathing was good but it seemed wrong to be dressed like this. I didn't know why. I I floated against the door, twisting the handle in fear that it wouldn't turn. The handle clanged as I pushed it down and I stared at to propel yourself through the passageway in this weightless atmosphere. It was effortless to move. I turned on my side like a swimmer and went hand over hand, shooting down the corridor. I braced against forward When I looked again I knew where I was. Why the little room had been shaped like quarter round. Why I drifted weightlessly. Why I was.... David Corbin. I knew more of the puzzle. Something was wrong. After the first shock WHY, Why, Why? The thought kept pounding at me. I was afraid to touch I pressed the button by the cot. The red lights blinked out as I stood "Tell me what to do," I shouted wildly. I hammered the hard metal until the pain in my hands made me stop. "I can't remember what to do." waking up in strangeness I had missed the other doors in the passage. The first swung back to reveal a deep closet holding five bulky suits. The second room was like my own. A dark haired, deep chested man lay on the cot. His muscular body was secured by a wide belt. He was as still as death, motionless without warmth or breath as I hovered over him. I couldn't remember his face. The next room held another man. He was young and wiry, like an athlete cast in marble, dark haired and big jawed. A glassy eye stared up when I rolled back his eyelid. The eyelid remained open until I closed it and went on. Another room ... another man ... another stranger. This man was tall and raw boned, light of skin and hair, as dead as the others. A flat, illogical voice had instructed me to revive these men. I that squatted on a shelf by his head. My hand shook when I touched half by the instrument studded shield. I retraced my steps and took a rough estimate of size. The ship, as I called it, was at least four hundred feet long, fifty feet in diameter on the inside. The silence was a force in itself, pressing down from the metal walls, driving me back to the comforting smallness of the room where I had could have hit my neck when I lay down. My shout of excitement rang out in the room, as I pictured the action of the extended arm. I lost my was completely closed, and it didn't yield to the pressure I applied. with the ship was a frightening force that seemed ready to break out of me. I went back to the cabin where the powerful man lay. I had to risk down the thought that he might be the key man, remembering the voice that had given the message. It was up to me, and soon. The metal in the box would have withstood a bullet. It couldn't be pried apart, and I drained under pressure and the arm moved back. I stood by the man for long minutes. Finally it came. He stirred restlessly, closing his hands into fists. The deep chest rose and fell unevenly as he breathed. Finally the eyes opened and he looked at me. I watched him adjust to the room. It was in his eyes, wide at first, "It looks like we made it," he said. "Yes." He unfastened the belt and sat up. I pushed him back as he floated up finding little humor in the comic expression on his face. "No gravity," he grunted and sat back. "You get used to it fast," I answered. I thought of what to say as he watched me. "How do you feel?" He shrugged at the question. "Fine, I guess. Funny, I can't remember." He saw it in my face, making him stop. "I can't remember dropping off to sleep," he finished. I held his hard arm. "What else? How much do you remember?" "I'm all right," he answered. "There aren't supposed to be any effects from this." name or anything about this ship." "What do you mean? What can't you remember?" he asked. He stood up slowly, edging around towards the door. I didn't want to fight him. I wanted him to understand. "Look, I'm in trouble. Nothing fits, except my name." "I feel all right physically. I just can't place enough." "The others. What about the others?" he blurted. The second man, the dark haired one, opened his eyes and recognized us. He asked questions in rapid fire excitement. The third man, the tall Viking, was all right until he moved. The weightless sensation made him violently sick. We put him back on the cot, securing him again with the belt, but the sight of us floating made him shake. He was retching The question frightened her. "Should I? I feel so strange. Give me a circled the room. "I'm afraid," she cried. I held her and she shook uncontrollably. "What's happened to me?" she asked. The dark haired man came into the room, silent and watchful. My "I can't remember when," I said. I held the trembling girl against me, shaking my head. He glanced at the girl. "If the calculations are right it was more than a metallurgist. His lean face was white from his spell but he was better. Paul Sample was a biologist, John said. He was lithe and "From Earth? How could we?" while we talked. "Don't think about it," Paul said. "We can still pull this out all I had a glimpse of his contorted face as I dove at the control board. My hands hit buttons, thumbed a switch and then a sudden force threw me control screen. It wasn't operating. John let go of the padded chair, grinning weakly. I was busy for a few seconds, feeding compensation into the gyros. Relief flooded through me like warm liquid. I hung on the intercom for support, drawing air into my heaving lungs. "What—made you—think of that," I asked weakly. "Shock treatment." "I must have acted on instinct." "You did. Even for a sick man that was pretty fast," he laughed. "I can think again, John. I know who I am," I shouted. I threw my arms around his massive shoulders. "You did it." "You gave me the idea, Mister, talking about Dr. Thiesen." "It worked. I'm okay," I said in giddy relief. "I wouldn't want to wake up like that again." "You're all right now?" he asked. I grinned and nodded an answer. I saw John as he was at the base, big and competent, sweating in the blazing sun. any one hurt?" "No. Carl is here too. His stomach flopped again but he's okay. What about food. We're supposed to be checked before we eat."
