The seats swung back to the at-rest position but Matt felt himself getting steadily heavier and knew thereby that

they were being centrifuged. He pressed against the pads, arms leaden, legs too heavy to move.

The feeling of extra weight left him, he felt his normal weight again, when suddenly that, too, was taken from him. He surged against the safety belts.

His stomach seemed to drop out of him. He gulped and swallowed; his breakfast stayed down. Somebody yelled, "We're falling!" It seemed to Matt the most unnecessary statement he had ever heard.

He set his jaw and braced himself for the bump. It did not come-and still his stomach seemed trying to squirm its way out of his body. Eleven seconds? Why, he had been falling more than eleven seconds already. What had gone wrong?

And still they fell, endlessly.

And fell.

Then he was forced back against the pads. The pressure increased smoothly until he was as heavy as he had been just before the drop. His abused stomach tried to retch but the pressure was too much for it.

The pressure eased off to normal weight. A short while later the car seemed to bounce and momentarily he was weightless, while his insides grabbed frantically for anchorage. The feeling of no weight lasted only an instant; he sagged into the cushions.

The door was flung open; the cadet strode in, followed by two medical technicians. Someone yelled, "Let me out of here! Let me out of here!" The cadet paid no attention but went to the seat in front of Matt. He unstrapped the occupant and the two medical assistants carried him out. His head lolled loosely as they did so. The cadet then went to the candidate who was kicking up the fuss, unstrapped him, and stepped back. The boy got up, staggered, and shuffled out.
