“That is hard to say. Friendship between alien intelligences is an imponderable. They are not dangerous, I think. We’ve come across other groups that could not maintain equilibrium after the atomic war stage and you know the results. Introversion. Retreat. Gradual decadence and increasing gentleness.”

“Even if they are such monsters?”

“The principle remains.”

It was about then that the Explorer felt the heavy throbbing of the engines.

He frowned and said, “We are descending a bit too quickly.”

There had been some speculation on the dangers of landing some hours before. The planetary target was a huge one for an oxygen-water world. Though it lacked the size of the uninhabitable hydrogen-ammonia planets and its low density made its surface gravity fairly normal, its gravitational forces fell off but slowly with distance. In short, its gravitational potential was high and the ship’s Calculator was a run-of-the-mill model not designed to plot landing trajectories at that potential range. That meant the Pilot would have to use manual controls.

It would have been wiser to install a more high-powered model, but that would have meant a trip to some outpost of civilization; lost time; perhaps a lost secret. The Merchant demanded an immediate landing.

The Merchant felt it necessary to defend his position now. He said angrily to the Explorer, “Don’t you think the Pilot knows his job? He landed you safely twice before.”

Yes, thought the Explorer, in a scout-ship, not in this unmaneuverable freighter. Aloud, he said nothing.

He kept his eye on the visi-plate. They were descending too quickly. There was no room for doubt. Much too quickly.
