reading back. A childish error, highly improbable; twice repeated, thus squaring the improbability. Incredible, but that's what happened.

"Anyway, we took good care with the next lot of measurements. That's 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 photographs of the Sun which I hoped would help to determine hydrogen density in the outer regions. When I got back everything was ready. We 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 to tear Charley limb from limb. Then James pressed the button.

"Everything twanged like a bowstring. I felt myself turned inside out, passed through a small sieve, and poured back into shape. The entire bow wall-screen was full of Earth. Something was wrong all right, and this time it was much, much worse. We'd come out of the jump about two hundred miles above the Pacific, pointed straight down, traveling at a relative speed of about two thousand miles an hour.

"It was a fantastic situation. Here 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 Whale also had ion rockets of course, the standard deuterium-fusion thing with direct conversion. As again you know, this is good for interplanetary flight because you can run it continuously and it has extremely high exhaust velocity. But in our situation it was no good because it has rather a low thrust. It would have taken more time than we had to 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 we stood in. The Minnow was meant for short heavy hops to planets or asteroids. In addition to the ion drive it had emergency atomic rockets, using steam for reaction mass. We thanked God for that when Cazamian canceled our downwards velocity with them in a few seconds. We curved away up over China and from about fifty miles high we saw the Whale hit the Pacific. Six hundred tons of mass at well over two
