<passage>:
She surely got her wish ... but there was some question about getting what she wanted. Phil Conover pulled the zipper of his flight suit up the front of his long, thin body and came into the living room. His face, usually serious and quietly handsome, had an alive, excited look. And the faint lines far. She said, "You look fine, Phil. You look just right." She managed a smile. Then she leaned forward and crushed the cigarette in the ash tray on the maple coffee table and took another from the pack. "Yes, I think so. Yes, I'm sure you did," she said, finishing the ritual but her voice broke, and she turned her head away. Phil sat isn't. We know exactly how it will be. If anything could go wrong, they She turned, facing him. There were tears starting in the corners of her wide, brown eyes, and she brushed them away with her hand. "Phil, don't go. Please don't. They can send Sammy. Sammy doesn't have a wife. Can't he go? They'd understand, Phil. Please!" She was holding his arms tightly with her hands, and the color had drained from her cheeks. "Mary, you know I can't back out now. How could I? It's been three years. You know how much I've wanted to be the first man to go. Nothing would ever be right with me again if I didn't go. Please don't make it released her and stood up. "I've got to get started, Mary. Will you come to the field with me?" "Yes, I'll come to say good-by." She paused and dropped her eyes. "Phil, if you go, I won't be here when you get back—if you get back. I won't be here because I won't be the wife of a space pilot for the rest of my life. It isn't the kind of life I bargained for. No matter how much I love you, I just couldn't take that, Phil. I'm sorry. I guess I'm not the noble sort of wife." She finished and took another cigarette from the pack on the coffee lighter to the end of the cigarette and drew deeply. Phil stood watching her, the excitement completely gone from his eyes. "I wish you had told me this a long time ago, Mary," Phil said. His voice was dry and low. "I didn't know you felt this way about it." "Yes, you did. I told you how I felt. I told you I could never be the wife of a space pilot. But I don't think I ever really believed it was possible—not until this morning when you said tonight was the take-off. It's so stupid to jeopardize everything we've got for a ridiculous dream!" man ever had the chance to do what I'm going to do tonight—no man ever. If I backed out now for any reason, I'd never be able to look at the sky again. I'd be through." She looked at him without seeing him, and there was nothing at all in her eyes. "Let's go, if you're still going," she finally said. existed only because of the huge ship standing poised in the take-off ready to stop existing as a town and to give itself back to the desert, if such was its destiny. Phil turned the car off the highway onto the rutted dirt road that led take-off zone and swept along the top of the high wire fence stretching out of sight to right and left. At the gate they were stopped by the guard. He read Phil's pass, shined his flashlight in their faces, and "Thanks, sergeant. I'll be seeing you next week," Phil said, and smiled. They drove between the rows of wooden buildings that lined the field, and he parked near the low barbed fence ringing the take-off zone. He surface gleamed in the spotlight glare, and it sloped up and up until "No, I've never seen her before," she said. "Hadn't you better go?" Her voice was strained and she held her hands closed tightly in her lap. "Please go now, Phil," she said. He leaned toward her and touched her cheek. Then she was in his arms, her head buried against his shoulder. "Good-by, darling," she said. "Wish me luck, Mary?" he asked. "Yes, good luck, Phil," she said. He opened the car door and got out. The noise of men and machines scurrying around the ship broke the spell of the rocket waiting silently for flight. "Mary, I—" he began, and then turned and strode toward the Inside the building it was like a locker room before the big game. The Phil had worn earlier. When he came into the room, the noise and bustle stopped. They turned as one man toward him, and General Small came up to him and took his hand. "Hello, Phil. We were beginning to think you weren't coming. You all set, son?" "Yes, sir, I'm all set, I guess," Phil said. As they crossed the room, familiar faces smiled, and each man shook his hand or touched his arm. He saw Sammy, alone, by the coffee urn. Sammy waved to him, but he didn't smile. Phil wanted to talk to him, to say something but there was nothing to be said now. Sammy's turn would come it didn't realize it at the time. Good luck, and God be with you." "Thank you, sir. I'm aware of all you say. It frightens me a little." The general took Phil's arm and they walked to the briefing room. There were chairs set up for the scientists and Air Force officers directly connected with the take-off. They were seated now in a semicircle in front of a huge chart of the solar system. Phil took his seat, and the last minute briefing began. It was a routine he knew by heart. He had The voice of the briefing officer was a dull hum in his ears. to 24,900-mph for five minutes and then free-coast for 116 hours until—" Phil asked a few questions about weather and solar conditions. And then the session was done. They rose and looked at each other, the same unanswered questions on each man's face. There were forced smiles and handshakes. They were ready now. "Phil," the general said, and took him aside. "Sir?" "Phil, you're ... you feel all right, don't you, son?" "Yes, sir. I feel fine. Why?" "Phil, I've spent nearly every day with you for three years. I know you psychologist's reports on you carefully. Maybe it's just nervousness, Phil, but I think there's something wrong. Is there?" "No, sir. There's nothing wrong," Phil said, but his voice didn't carry conviction. He reached for a cigarette. "Phil, if there is anything—anything at all—you know what it might mean. You've got to be in the best mental and physical condition of your life tonight. You know better than any man here what that means to our Outside, the take-off zone crawled with men and machines at the base of The small group at the base of the ship turned and walked back to the For a long time after the rocket had become a tiny speck of light in the herself. And then she felt the touch of a hand on her arm. She turned. "Phil! Oh, Phil." She held tightly to him and repeated his name over and over. "They wouldn't let me go, Mary," he said finally. "The general would not let me go." She looked at him. His face was drawn tight, and there were tears on his cheeks. "Thank, God," she said. "It doesn't matter, darling. The only thing that matters is you didn't go." "You're right, Mary," he said. His voice was low—so low she could hardly hear him. "It doesn't matter. Nothing matters now." He stood with his hands at his sides, watching her. And then turned away and walked THE END
