“Now, all of you turn the little black knob on your chests,” the tester said. His voice sounded muffled to Gib because of the helmet he wore. Gib turned his knob and felt his suit blowing up like a balloon as air flowed in from the oxygen tanks. “This is how you would be dressed for a walk on the Moon,” the tester told them. “Now I want all of you to walk into the next room.” As Gib went into the room with the others, he was thinking how easy the test had been up until now. And what fun it was taking the very tests that Captain Rocket himself must have taken at one time! He thought his father was surely mistaken for having doubted his ability to pass the S.Q.T. The tester left the room and shut the door. In a few moments Gib began to have a strange sensation. He was feeling lighter and lighter, and the others with him were beginning to float right off the floor! Gib struggled frantically as he felt himself go off balance. Each movement he made, however, shot him off at swift, crazy angles. He felt himself sweating with fear, and for the first time he was believing that maybe the S.Q.T. wasn’t going to be so easy after all. It seemed as if he had the strength of a Samson, but it was a strength he could not control. A simple kick sent him hurtling across the room toward the wall! He tried to brake himself, but nothing he did would stop him. He crashed headlong into the wall. It shook him up a little, but he was not hurt. He saw that the wall was thickly padded. After about fifteen minutes of helplessness, Gib felt himself getting heavier again and saw his companions drop to the floor in normal position. The tester came in with some doctors. The doctors looked over each candidate and asked many questions. Gib was still dazed and wasn’t sure of the answers he gave. When the doctors were through, the tester explained what had happened: “This room was de-gravitized, which means the Earth’s gravity in here was cut off by mechanical means. It’s the same condition you will find in a space ship when the gravity plates are turned off. From the looks of some of you, this experience was something of a shock. But the final test will be even rougher. Anybody who wants to drop out now may do so.” Gib saw that about a third of the candidates had had enough. Gib was still giddy himself and started to join them. He was disappointed in the harshness of “zero-gravity.” It had always looked so simple to him the way that Captain Rocket “swam” about in his rocket flyer. Gib did not want his father to think him a quitter, though, and decided to stick out the test to the end. When his turn came, he was led into a huge room by himself and up to a queer-looking machine. It resembled one of the thrill rides at a carnival, the one that whirls you round and round like a ball on the end of a string. Gib entered a tiny cabin at the end of the large swinging arm and sat down in a thick foam-rubber reclining chair.
