 Upon landing, Craig is greeted by whom?
Flight Officer Robert Craig surrendered the tube containing his service record tapes and stood waiting while the bored process clerk examined the seal. Craig obeyed the robot voice and began reluctantly to remove his flight jacket. On the eighth day, two attendants, who showed the effects of massive doses of PON to protect themselves from the centrifugal force, had to carry a man out of the tank. "The twelfth day is the worst," a grizzled spaceman told Craig. The huge headquarters base centrifuge aboard the man-made satellite had gradually caused their bodies to respond once more to a single source of pull. They were now ready to become inhabitants of planets again, instead of free-falling ships. Then they again began taking paraoxylnebutal in preparation for the free-fall flight to Terra.
