They went out of the lock. Sanford suddenly peeled off his metal-soled slippers, put them in his pocket, and dived casually into a four-foot metal tube. He drifted smoothly away along the lighted bore, not touching the sidewalls. He moved in the manner of a dream, when one floats with infinite ease and precision in any direction one chooses.
Joe and Mike did not share his talent. Joe launched himself after Sanford, and for perhaps 20 or 30 feet the lighted aluminum sidewall of the tube sped past him. Then his shoulder rubbed, and he found himself skidding to an undignified stop, choking the bore. Mike thudded into him.
"I haven't got the hang of this yet," said Joe apologetically.
He untangled himself and went on. Mike followed him, his expression that of pure bliss. He was a tiny man, was Mike, but he had the longings and the ambitions of half a dozen ordinary-sized men in his small body. And he had known frustration. He could prove by mathematics that space exploration could be carried on by midgets at a fraction of the cost and risk of the same job done by normal-sized men. He was, of course, quite right. The cabins and air and food supplies for a spaceship's crew of midgets would cost and weigh a fraction of similar equipment for six-footers. But people simply weren't interested in sending midgets out into space.
But Mike had gotten here. He was in the Space Platform. There were full-sized men who would joyfully have changed places with him, forty-one inch height and all. So Mike was blissful.
The tube ended and Joe bounced off the wall that faced its end. Sanford was waiting. He grinned with more than a hint of spite.
"Here's our communications room," he said. "Now you can talk down to Earth. It'll be relayed, now, but in half an hour you can reach the Shed direct."
He floated inside. Joe followed cautiously. There was another crew member on duty there. He sat before a group of radar screens, with thigh grips across his legs to hold him in his chair. He turned his head and nodded cheerfully enough.
"Here!" snapped Sanford.
Joe clambered awkwardly to the seat the senior crew member pointed out. He made his way to it by handholds on the walls. He fumbled into the chair and threw over the curved thigh grips that would hold him in place.
