CAPTAIN CHAOS By D. ALLEN MORRISSEY Science equipped David Corbin with borrowed time sent him winging out in a state of suspension to future centuries ... to a dark blue world whose only defense was to seal tight the prying minds of foolish interlopers. "Your name is David Corbin. Do you understand?" "Your name is David Corbin. If you understand, press button A on your "Your name is David Corbin." David Corbin. I knew more of the puzzle. Something was wrong. After the first shock of looking out, I accepted the fact that I was in a space ship, yet I couldn't read the maps that were fastened to a table, nor understand the function or design of the compact machinery. "Your name is David Corbin. If you understand, press button A on your the clear portholes. "It is assumed the experiment is a success," the voice said. What experiment? "You have been removed from suspension. Assume manual control of this ship." Control of a ship? Going where? "Do not begin operations until the others are removed from suspension." What others? Tell me what to do. "Rely on instructions for factoring when you check the coordinates. Your maximum deviation from schedule cannot exceed two degrees. Adopt emergency procedures as you see fit. Good luck." instructions without knowledge were useless to me. I stopped looking into the doors in the passageway and went back to the room with the portholes. Everything lay in readiness, fastened down star charts, instruments, glittering equipment. There was no feeling of disorder or use in the room. It waited for human hands to make it operate. Searching the ship made me forget my fear. I hoped I would find some answers. I went from the nose to the last bulkhead in a frenzy of floating motion, looking behind each door until I went as far as I could. There were two levels to the ship. They both ended in the lead shield that was set where the swell of the curve was biggest. It meant the engine or engines took up half the ship, cut off from the forward 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 sent along to safeguard the others. Complete amnesia would have been terrible enough but this half knowledge, part awareness and association 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 "I'm all right," he answered. "There aren't supposed to be any effects from this." "Who is in charge of this ship?" I asked. He tensed suddenly. "You are, sir. Why?" I moved away from the cot. "Listen, I can't remember. I don't know your name or anything about this ship." quarters. "What about her. Why is she here?" I asked my companion. He lifted the cover from the apparatus. "She's the chemist in the crew." "I suppose. The mission stated one chemist." "What is the mission of this ship?" I asked. He held up his hand. "We'd better wait, sir. Everything was supposed to be all right on this end. First you, then Carl, sick to his stomach." companion motioned to him. "Get Carl and meet us in Control." The man looked at me and I nodded. "We'll be there in a moment. I'm afraid we've got trouble." "John, what are your duties if any?" "Automatic control. I helped to install it." "Can you run this ship? How about the other two?" He hit his hands together. "You fly it, sir. Can't you think?" "I'm trying. I know the ship is familiar, but I've looked it over. Maybe I'm trying too hard." "You flew her from earth until we went into suspension," he said. a hundred years ago." We assembled in the control room for a council. We were all a little better for being together. John Croft named the others for me. I I wasn't in much better condition. "Look, if it comes too fast for me, for any of us, we'll stop. John, you can lead off." "You ask the questions," he said. I indicated the ship. "Where in creation are we going?" "We set out from Earth for a single star in the direction of the center of our Galaxy." "From Earth? How could we?" "Let's move slowly, sir," he said. "We're moving fast. I don't know if you can picture it, but we're going about one hundred thousand miles an hour." "Through space?" "Yes." "What direction?" Paul cut in. "It's a G type star, like our own sun in mass and luminosity. We hope to find a planetary system capable of supporting life." "It can be done in two lifetimes," John said quietly. "You said I had flown this ship. You meant before this suspension." "Yes. That's why we can cross space to a near star." "How long ago was it?" "It was set at about a hundred years, sir. Doesn't that fit at all?" right if you don't lose your nerve." "What are we to do?" she asked. John answered for me. "First we've got to find out where we are. I know this ship but I can't fly it." "Can I?" I asked. We set up a temporary plan of action. Paul took Karen to the laboratory in an effort to help her remember her job. Carl went back to divide the rations. I was to study the charts and manuals. It was better than doing nothing, and I went into the navigation room and sat down. Earth was an infinitesimal point somewhere behind us on the galactic plane, and no one else was trained to navigate. The ship thundered to life as I sat there. The blast roared once ... twice, then settled into a muted be shocked out of a mental state like that." "I guess you're right," he said slowly. "She's trained to administer the suspension on the return trip." through the stillness. John was shouting as I thrust my way into the room. "Turn the ship. There's something dead ahead." 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 John as he was at the base, big and competent, sweating in the blazing sun. I thought about the rest of the crew too. "We're heading right for a star...." "It's been dead ahead for hours," he grunted. I leaned over and threw the intercom to open. "This is control. Listen ... everyone. I'm over it. Disregard the warning siren ... we were testing the ship." The lab light blinked on as Paul cut in. "What was it ... hey, you said "No, I put her to bed. Shall I bring food?" I glanced at John. He rubbed his stomach. "Yes," I answered. "Bring it when you can. I've got to find out where we are." We had to get off course before we ran into the yellow-white star that had been picked for us. Food was set down by me, grew cold and was carried away and I was still rechecking the figures. We were on a line ten degrees above the galactic plane. The parallactic baseline from Earth to the single star could be in error several degrees, or we could the screen gave us the distance and size of the star while we fed the figures into the calculator for our rate of approach. own. It had more density and temperature and suitable planets or not, we had to change course in a hurry. Carl analyzed the findings while we came to a decision. Somewhere along an orbit that might be two hundred miles across, our hypothetical planet circled this star. That distance was selected when the planets in Earth's solar system had proved to be barren. If the observations on this star were correct, we could expect to find a planet in a state of fertility ... if it existed ... if it were suitable for colonization ... if we could find it.
