<passage>:
When a ship is working perfectly and is operated by a hand-picked crew of highly trained men in perfect condition, how often is it wrecked by a series of silly errors happening The most probability? "I'll sign off with two thoughts, one depressing and one cheering. A single Chingsi wrecked our ship and our launch. What could a whole planetful of them do? The "On the other hand, a talent that to be chancy. No matter how highly developed it can't be surefire. The proof is that I've survived to tell the tale." At twenty below zero and fifty thing of metal and plastics, an artifact Nothing grew, nothing flew, nothing walked, nothing talked. But the THE END Astounding Science Fiction success. It's well on the cards that I'm all in one piece and not broken up at all, though I don't see how it could happen. Right now I don't one after another in defiance of well use it. That way even if I'm not and wonder what went wrong. age it was luck. "You'll want to know if the ship worked. Well, she did. Went like a use. Better yet would be a pint Whale till right at the end and even then I doubt if it was the ship itself that fouled things up. "That was some survey assignment. We astronomers really lived. at fifteen p.s.i. The odds technical—haven't got space travel for instance. They're good astronomers, though. We were able to show "One, they learned our language in four weeks. When I say they, I mean a ten-man team of them. had aboard the Whale . "Three, they've a great sense of humor. Ran rather to silly practical jokes, but still. Can't say I care for that hot-foot and belly-laugh stuff myself, but tastes differ. "Four, the ten-man language team also learned chess and table tennis. "But why go on? People who talk English, drink beer, like jokes and beat me at chess or table-tennis are people for my money, even if they look like tigers in trousers. "It was funny the way they won all the time at table tennis. They certainly weren't so hot at it. Maybe that ten per cent extra gravity put us sometimes. The rest of us seemed to they were good. How could they be, in the time? It was more that we all seemed to make silly mistakes when we played them and that's fatal in chess. Of course it's a screwy situation, "And don't think I fell victim to or whatever you like to call him, who came back with us. Why I disliked him was because he was always trying to get the edge on you. All the time he had to be top. Great sense of humor, of course. I nearly broke my neck on that butter-slide he fixed up in the metal alleyway to the Whale's engine room. Charley laughed fit to bust, everyone laughed, I even laughed myself though doing it hurt me more than the tumble had. Yes, life and soul of the party, old Charley ... "My last sight of the was a cabin full of dead and dying men, the sweetish stink of burned flesh and the choking reek of scorching insulation, the boat jolting and shuddering and beginning to break up, and in the middle of the flames, still unhurt, was Charley. He was laughing ... "My God, it's dark out here. Wonder how high I am. Must be all of same as escape "It's getting lighter. Look at those I expected though. Almost seem to be and the suit recorder has no playback or eraser. What must have happened is that the suit ran out of oxygen, and I lost consciousness due to anoxia. I dreamed I switched on the radio, but I actually switched on the emergency tank, thank the Lord, and that brought me round. "Come to think of it, why not "I was telling about the return our exact position relative to the solar system. The crew had to find out exactly what went wrong. The physicists had to make mystic passes in front of meters and mutter about residual folds in stress-free space. Our task was easy, because we were about half a light-year from the sun. The crew's job was also easy: they found what went wrong in less than half an hour. "It still seems incredible. To program the ship for a star-jump, you merely told it where you were and terms, that entailed first a series of Nothing was wrong with the you this and I'm just attached personnel with no space-flight tradition. In practical terms, one highly trained crew member had punched a wrong pattern of holes on the tape. Another this when reading back. A childish thus squaring the improbability. Incredible, but that's what why we were out there so long. They were cross-checked about five times. I got sick so I climbed into a spacesuit and went outside and took some disposed ourselves about the control room and relaxed for all we were worth. We were all praying that this time nothing would go wrong, and all looking forward to seeing Earth again after four months subjective time away, except for Charley, who was still chuckling and shaking his head, and Captain James who was glaring at Charley and obviously wishing human dignity permitted him was the Whale , the most powerful ship ever built, which could cover fifty light-years in a subjective time of one second, and it was helpless. For, as of course you know, the star-drive couldn't be used again for at least two hours. "The As again you know, this is good for deflect us enough to avoid a smash. We had five minutes to abandon ship. "James got us all into the Minnow at a dead run. There was no time to take anything at all except the clothes was meant it had emergency atomic rockets, using steam for reaction mass. We splash. By now you'll have divers down, but I doubt they'll salvage much you can use. "I wonder why James went down with the ship, as the saying is? Not that it made any difference. It must have broken his heart to know that his lovely ship was getting the chopper. about that, or even to get the radio working. The steam rockets blew up. Poor Cazamian was burnt to a crisp. Only thing that saved me was the spacesuit I was still wearing. I snapped the face plate down because the cabin was filling with fumes. I saw Charley coming out of the toilet—that's how he'd escaped—and I saw him beginning to laugh. Then the port side collapsed and I fell out. earth fifty miles below. I shut my eyes and that's about all I remember. I don't see how any of us could have survived. I think we're all dead. "I'll have to get up and crack this suit and let some air in. But I can't. "Hello there. I'm in the bleakest makes the moon look cozy. There's The suit is bulky but light and probably watch out for them. Those jokers are dangerous. I'm not telling how because I've got a scientific reputation to watch. You'll have to figure it out for yourselves. Here are the clues: (1) The Chingsi talk and laugh but talents develop? A talent that's here that most people don't believe Whale expedition did fine till it found Chang. Then it hit a seam of bad luck. Real stinking bad luck that went on and on till it looks fishy. We lost the ship, we lost the launch, all but one of us lost our lives. We couldn't even win a game of ping-pong. "So what is luck, good or bad? Scientifically speaking, future chance can turn out favorable or not. When a preponderance of chance events has luck. It's a fancy name for a lot of For him, luck refers to the others aren't. All we've got are hints and glimmers, the fumbling touch of a rudimentary talent. There's the evil eye legend and the Jonah, bad luck bringers. Superstition? Maybe "All the same, search the space-flight records, talk to the actuaries.
