"I think they will," MacIlheny said. "Their technology must be similar to ours or he wouldn't have been able to figure out how to fire the jets on the satellite or how to set off that bomb. He wouldn't have even known what the bomb was unless he was familiar with something similar. And he wouldn't have been able to blank out our controls unless he had a good idea of how they operated. They may be a little ahead of us, but not too much, and I'll bet we have some things they haven't."
"The trouble is," the President said worriedly, "that we don't know where he came from. He knows where we are, but we don't have any idea where his home planet is."
"That's true. On the other hand, we know something about his physical characteristics, while he doesn't know anything about ours. For instance, I doubt if he'd be happy here on Earth; judging by the helmet he wore, he can't stand too much light. He had it polarized almost black. Probably comes from a planet with a dim, red sun."
"Well, Fitz, when they do come, I hope it's for trade and not for war."
MacIlheny grinned. "It won't be war. Don't you remember? We've started trading already!"
