the entire ship and crew were as good as dead! lines, aboard my spaceship. They are always so anxious to please. They has a very low life expectancy on Earth due to the automobiles they are open a planet to colonization or even fraternization, they insist on Accident Prones can find out what is wrong with a planet as easily planet and a Prone will be knee-deep in it within an hour of blastdown. All of this is properly recorded for the next expedition in the stars often visit you in the hospital. begin our re-survey of the planet. It was Charlie's first assignment, so we had an easy one—just seeing if anything new had developed in the last fifty years. Baxter's guard was doubled as soon as we set down, of course, and that made him fidgety. He had heard all the stories about how high Actually Charlie was safer in space than he would be back on Earth himself. I believe accident prones have a better system of calculation than a cybernetic machine. They can take everything into consideration—the infallibly make the right choice in any given situation. Then, because they are incapable of trusting themselves, they do exactly the opposite. His clumsiness back on Earth had cost him every decent job he ever had. for the position of Prone aboard a spaceship. He had been poor—hungry, would come precariously close to killing to keep it. Or to being killed. He was ready to work. this, much less Baxter's bed in the next cabin. But then I am only a captain. Bronoski to follow me. The engines on the effort was spared to insure comfort for the key man in the whole crew. were missing. Baxter had left the spaceship and gone off into an alien interfering in any way with a Prone's decisions. They merely had to follow him and give their lives to save his, if necessary. for the report before leaving the ship. The envelope contained the exploration survey on Moran III made some fifty years before. I unlocked a desk drawer with my thumb print and drew out a duplicate of the report. I didn't have too much confidence in it and I hoped Charlie Baxter had less. Lots of things can change on a planet in fifty years, including its inhabitants. perfectly shielded. I read that before the last exploration party had skinny . How skinny? Well, the only curves they had in their bodies were their bulging eyeballs. But just because they were thin didn't mean they were pushovers. Whips and garrotes aren't fat and these looked just as dangerous. Whenever I see aliens who are so humanoid, I remember all that Sunday supplement stuff about the Galaxy being colonized sometime by one humanlike race and the Ten Lost Tribes and so forth. colonies that it would take a terrestrial season to tour by animal cart. the fatal error. The three men were just standing still, waiting for the aliens to make cybernetic unit back on board the spaceship tried decoding the words. times he could never stay on his feet. Before he could perform his usual pratfall, Sidney and Elliot were at his sides, supporting him by his thin biceps. He glared at them and shrugged them off, informing them wordlessly that he would have regained his balance if they had given him half a chance. contempt as to claim all Terrestrial. I've read stories where explorers wearing translators and if you pay very close attention, you can find minor semantic differences in the original words and the echo translated back from a I was trying to catch both versions from Charlie. I knew he was making a mistake and later I wanted to be sure I knew just what it was. Frankly, I would have used the blood-brother gambit myself. I had also read about it in the survey report, as I made a point of telling you. This just proves that Accident Prones haven't secured the franchise on mistakes. The difference is that I would have gone about it a lot more cautiously. down by a spare dozen of the mob. It all meant one thing to me. The reaction of the crowd had been was my turn to grind his face in the muck. I had a nice little problem to contend with. I knew the reason Baxter had slipped out at night to be the first to greet the aliens. He was determined to be useful and necessary without of fissionable material and just keeping them from uniting and making a critical mass that will result in an explosion or lethal radiation. I caught my oldest boy doing it one day back on Earth and gave him a flashbulb, but it exploded only about ten times as loud as a pistol shot. The mass hadn't been slapped together hard enough or held long The natives weren't fools, though. They got out of there fast. I wished Baxter, his two guards and the native spokesman. Charlie and the native were both technically unconscious, but they each had a stranglehold on each other, with Charlie getting the worst of it. on, but he didn't seem to mind. We knew enough not to use the blood-brothers approach after fifty years and therefore it did not take us long to find out why we shouldn't. three Earth months. It seems a waste at first thought, but all things are relative. The Crystopeds of New Lichtenstein, for instance, have a life span of twenty thousand Terrestrial years. a lot of variables introduced, resulting in change. The idea that seemed to be in favor was the survival of the fittest. Since the natives were born in litters, with single births extremely rare, this concept was practiced from the first. Unless they were particularly cunning, the runts of the litter did not survive the first year and rarely more than one sibling ever saw adulthood. preliminaries that preceded every encounter. We got pretty good results the half century. But finally one of the men—either Frank Peirmonte or Sidney Charterson, who both claim to be the one—thought of calling the crew a Family and right away we began hitting it off famously. about the previous visit of Earthmen and they didn't trust us. and we could get on with the re-survey of the planet. while you lay there, haven't you, Baxter?" "Yes, sir. I see I've been fighting this thing too hard. I am an ? I know I can't change it." developing a certain amount of doomed self-confidence, but they couldn't be allowed to believe they were infallible Prones. A Prone's around in that jungle until a tree falls on you?" He sat down on the edge of the bed and examined the pattern in the carpet. "Not exactly, sir. But I get tired of people waiting for me to make a fool out of myself. I have a natural talent for—for Creative Negativism . That's it. And I should be able to exercise my talent with dignity ." every moment?" "I can take care of myself, sir!" I paused and came up with my best argument. "How would you like to Because if you're not our Accident Prone, you're just another crew I snorted. "It takes skill and training, Baxter. Your papers entitle you to one position and one only anywhere—Accident Prone of a spaceship complement. If you refuse to do your duties in that post, you any other high mortality rate among Accident Prones in space, too." Actually, most Prones died of old age in space, which is more than could be said of them on Earth, where they didn't have the kind of back on Earth before the building I was working in burned down." "But there I would have some chance of advancement higher pay or more privileges than Prone is Grand Admiral of the Services, a position it would take you at least fifty years to reach if violent as being eaten by floating fungi or being swallowed in an earthquake on some airless satellite." "No," I agreed, "it is much slower than any of those. It is unfortunate care of the rest of us only if he has time left over from you. Why, when I was having my two weeks in the summer as an Ensign, I had to holding him down into the miserable overpaid, overfed job that was beneath him and the talents that so fitted him for the job. "Request granted." He would learn. He had better.
