"Cut it out, Mike," he said, coming as near to a snap as his careful voice could manage. He blew smoke out around the stem of his pipe. I think sometimes it's a part of his act, like the slightly-out-of-press sports jacket and flannel trousers. It says he is a sure enough Ph.D. If you ask me, he's a comer. You can't rate him for lack of brains. He knows an awful lot about solid-state physics, and for a physicist, he sure learned enough about micro-assemblies of electronic components. I guess that's why he was in charge of final assembly of the Telstar satellites for COMCORP. "Don't worry about what Paul Cleary can do _to_ you, Mike," he suggested. "Think a little bit more about what Fred Stone can do _for_ you. Cleary is only a year or so from retirement, and you know it." "He could make that an awful tough year, Doc." I said. "You told me he won't hear of design bugs in that solenoid. He'll insist something went wrong in assembly." Doc Stone smiled thinly at me and brushed at his blond crew cut. "It is a tough spot, Mike," he agreed. "Because I won't hear any talk of faulty assembly. You'll have to choose, I guess. If you think you can make your bed by playing footsie with an old fud who has only a year to go, try it. Just remember that I've got another thirty years to go, and I'll breathe down your neck every minute of them if you let me down!" "Sure," I said. "When do I see him?" "Now." * * * * * Doc Stone got someone named Sylvia on the phone and then told me to go right up. After I got there, I had to sit and wait in Cleary's outer office. I shared it with a small, intense girl named Sylvia Shouff, if you believed the little plastic sign on her desk. There was barely room for it in the welter of paper, files, notebooks, phones, calendars and other junk she had squirreled. She was much too busy banging at a typewriter and handling the phone to pay any attention to me. Her pert, lively manner said she hadn't taken any wooden nickels lately. But I had. The last series of tests in my lab had put me in the middle of a hell of a scrap. It had all started a couple years back, when the final design had been approved for a whole sky-full of communications satellites. Well, eighteen, to be exact. One of the parts in the design had been a solenoid, part No. M1537, which handled a switching operation too potent for a solid-state switch. That solenoid was one of the few moving parts in the Telstars, and it had been designed for skeighty-eight million cycles before it got sloppy or quit. In practice, out in space, the switching operation simply hadn't worked. After about a hundred hours of use in Telstar One, it failed. Unfortunately, this had not been discovered until the first six satellites had been launched. Further launchings were postponed while they ran accelerated switching tests on satellites Two through Six out in space. The same kind of failure took place on each bird.
