Joe saw the other man in the room, the man at the radar screens, shake his head. He got up and fumbled his way along the wall to the door. Sanford shouted after him angrily.
Joe went out, found the four-foot tunnel, and floated not down but along it back to the unloading lock. Wordlessly, he set to work to get the cargo out of the cargo hold of the spaceship.
Handling objects in weightlessness which on Earth would be heavy was an art in itself. Two men could move tons. It needed only one man to start a massive crate in motion. However, one had either to lift or push an object in the exact line it was to follow. To thrust hard for a short time produced exactly the same effect as to push gently for a longer period. Anything floated tranquilly in the line along which it was moved. The man who had to stop it, though, needed to use exactly as much energy as the man who sent it floating. He needed to check the floating thing in exactly the same line. If one tried to stop a massive shipment from one side, he would topple into it and he and the crate together would go floundering helplessly over each other.
The Chief had gone off to help maneuver two-ton guided missiles into launching tubes. One crew member remained with Haney, unloading things that would have had to be handled with cranes on Earth. Joe found himself needed most in the storage chamber. A crate floated from the ship to the crewman. Standing head downward, he stopped its original movement, braced himself, and sent it floating to Joe. He braced himself, stopped its flight, and very slowly—to move fast with anything heavy in his hands would pull his feet from the floor—set it on a stack of similar objects which would presently be fastened in place.
Everything had to be done in slow motion, or one would lose his footing. Joe worked painstakingly. He gradually began to understand the process. But the muscles of his stomach ached because of their continuous, instinctive cramp due to the sensation of unending fall.
Mike floated through the hatchway from the lock. He twisted about as he floated, and his magnetized soles clanked to a deft contact with the wall. He said calmly: "That guy Sanford has cracked up. He's potty. If this were jail he'd be stir-crazy. He's yelling into the communicator now that we'll all be dead in a matter of days, and the rocket missiles we brought up won't help. He's nasty about it, too!"
Haney called from the cargo space of the ship in the lock: "All empty here! We're unloaded."
There were sounds as he closed the cargo doors. Haney, followed by the Chief, came into view, floating as Mike had done. But he didn't land as skillfully. He touched the wall on his hands and knees and bounced away and tried helplessly to swim to a hand-hold. It would have been funny except that Joe was in no mood for humor.
Mike whipped off his belt and flipped the end of it to Haney. He caught it and was drawn gently to the wall. Haney's shoes clicked to a hold. The Chief landed more expertly.
"We need wings here," he said ruefully. "You reported, Joe?"
