"On course," he said to the radio. "The transmitters are pointing a little northwest of Philadelphia."

"Good," Arnoldsson's voice answered. "Now, your next blast should be three seconds' duration in the same direction...."

"No," Tom said, "I've gone as far as I'm going to."

"What?"

"I'm not moving the satellite any farther."

"But you still have not enough fuel to return to Earth. Why are you stopping here?"

"I'm not coming back," Tom answered. "But I'm not going to beam the satellite's power to the settlement, either."

"What are you trying to pull?" Jason's voice. Furious. Panicky.

"It's simple, Jason. If you want the satellite's power, you can dismantle the settlement and carry it to Pennsylvania. The transmitters are aimed at some good farming country, and within miles of a city that's still half-intact."

"You're insane!"
