"We're lucky we still have him, Mother." Jak's voice was serious. "If that rock had even touched him, it would have been the end. His leg looks OK—no signs of swelling or inflammation."

Breakfast was quiet, and as soon as they finished Jon rose purposefully. "I'll take us up now, and we'll cruise around and see what we can see. Have to take lots of recordings and pictures, you know."

"Are you sure you understand all that has to be done?" His mother's voice was anxious.

"Sure, Mom. It tells all about it on the papers the Colonial Board furnished. All we have to do is follow their instructions. You coming, Jak?"

"Right with you." His brother hastily drank the rest of his coffee and rose, wiping his mouth. "Be sure you strap down at the signal, Mother, if you aren't coming with us."

She flashed him a smile. "I will. Meanwhile, I'll clear the table—if I have time?" She looked questioningly at Jon.

"Sure, it'll take ten—fifteen minutes to get ready, and I'll give you a couple of one-minute warnings."

When all was ready, Jak strapped himself down in the co-pilot's seat, the book of instructions in his hand. Jon touched the stud of the buzzer, waited a full minute then punched two buzzes. Then he nodded at his brother.

"Close fuel dump valves," Jak said, referring to the manual.

"Valves closed."
