 Was the ship on target, within maximum deviation from schedule?
The curve met another straight bulkhead on the left. There was no sensation of place, no feeling of up or down, no direction. That I was floating in a room that had a curved wall ... that nothing was right in this hostile room? 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. It was the only thing I saw that could help me, guard me against another shock like seeing outside of the clear portholes. Your maximum deviation from schedule cannot exceed two degrees. 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. 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? 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. 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.
