“_What?_” Jordan’s voice rattled the speaker. “Of course not! It took two accidents to get the thing back to us—and with a half-light-year miss that delayed it about twenty years before the Procyon shuttle heard its signal. Pre-setting a course may take centuries, if we can ever master it. Even with Sirius expecting the missiles and ready to cooperate. I mean the big ship. We’ve had it drafted for building long enough; now we can finish it in three months. We know the drive works. We know it’s fast enough to reach Procyon in two weeks. We even know life can stand the trip. The rats were unharmed.” Giles shook his head at what the other was proposing, only partly believing it. “Rats don’t have minds that could show any real damage such as the loss of power to rejuvenate. We can’t put human pilots into a ship with our drive until we’ve tested it more thoroughly, Bill, even if they could correct for errors on arrival. Maybe if we put in stronger signaling transmitters....” “Yeah. Maybe in two centuries we’d have a through route charted to Sirius. And we still wouldn’t have proved it safe for human pilots. Mr. Giles, we’ve got to have the big ship. All we need is _one_ volunteer!” It occurred to Giles then that the man had been too fired with the idea to think. He leaned back, shaking his head again wearily. “All right, Bill. Find me one volunteer. Or how about you? Do you really want to risk losing the rest of your life rather than waiting a couple more centuries until we know it’s safe? If you do, I’ll order the big ship.” Jordan opened his mouth and for a second Giles’ heart caught in a flux of emotions as the man’s offer hovered on his lips. Then the engineer shut his mouth slowly. The belligerence ran out of him. He looked sick, for he had no answer. * * * * * NO SANE man would risk a chance for near eternity against such a relatively short wait. Heroism had belonged to those who knew their days were numbered, anyhow. “Forget it, Bill,” Giles advised. “It may take longer, but eventually we’ll find a way. With time enough, we’re bound to. And when we do, the ship will be ready.” The engineer nodded miserably and clicked off. Giles turned from the blank screen to stare out of the windows, while his hand came up to twist at the lock of hair over his forehead. Eternity! They had to plan and build for it. They couldn’t risk that plan for short-term benefits. Usually it was too easy to realize that, and the sight of the solid, time-enduring buildings outside should have given him a sense of security. Today, though, nothing seemed to help. He felt choked, imprisoned, somehow lost; the city beyond the window blurred as he studied it, and he swung the chair back so violently that his hand jerked painfully on the forelock he’d been twisting. Then he was staring unbelievingly at the single white hair that was twisted with the dark ones between his fingers.
