 What did David determine the black box was for?
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. [Transcriber's Note: This etext was produced from Planet Stories November 1952. There were round dials set in a row above a speaker. Over the mesh-covered speaker, two knobs glowed red. The mesh-covered hole and the two lights looked like a caricature of a face, set in a panel of dials. I reached down to the tightness that held my body, found the wide strap that held me and fumbled with the buckle. There was no sensation of place, no feeling of up or down, no direction. a door to my left that appeared to be air tight. "Your name is David Corbin." The name meant nothing to me, but I thought about it, watching the relentless lights that shone below the dials. I was naked except for heavy shorts, and there was no clue to my name in the pockets. I reasoned it was there to propel yourself through the passageway in this weightless atmosphere. 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. Now it must tell me why I didn't. It must tell me.... It was the only thing I saw that could help me, guard me against another shock like seeing outside of the clear portholes. The first swung back to reveal a deep closet holding five bulky suits. He was as still as death, motionless without warmth or breath as I hovered over him. The eyelid remained open until I closed it and went on. I dared not try to operate anything. Everything lay in readiness, fastened down star charts, instruments, glittering equipment. It waited for human hands to make it operate. This room was filled with equipment that formed a room out of the bordered area I stood in. I sat in the deep chair facing the panel of dials and instruments, in easy reach. The ports on the side were shielded and I stared out at static energy, hung motionless in a world of searing light. There was no distortion, no movement outside and I glanced back at the dials. What speeds and perhaps, what distance? They stood for anything I might guess, and something kept pricking my mind, telling me I had no time to guess.
