"Me, of course." His father bared his arm. "Jon has to be awake last to handle the controls."

Again Jak filled his needle, and as carefully as before he injected the sleeping drug into his father. Then he stepped up to the pilot's pressure pack where his younger brother was adjusting the controls. "Ready, Jon?"

"Just a sec." The boy was still working, pushing in a button there, turning a switch here, stopping to tighten a wire or connection somewhere else. But in a few moments he had finished, and then rested his right hand on the handle of the master switch, ready to push it into contact.

But just as Jak brought the needle close to his arm the younger boy pushed it away. "Wait now, Jak. How about you? Can you make it to your pack and get in and strapped down and settled, and then give yourself the shot before I throw the switch and the five G's take effect?"

"Don't worry about me," his brother said gruffly. "I'll make out some way."

"Not good enough," Jon said positively. "Let's figure this down to seconds. If I don't close the switch before I black out, all this'll be wasted. How about if you inject yourself first? Will you have time enough to give me my shot and then get back into your pack and strap down before you go under?"

Jak thought swiftly a moment. "Your point's well taken, Jon, but you didn't figure it right. Your way, I'd have to give you your injection besides doing all the rest in the same length of time. If I give you yours first, I can get into my pack and give myself mine there. You merely stay awake until I'm done."

"Yes, guess you're right. But fix your pack so you can be sure of getting in without any trouble."

Jak did this, then came back, filled the needle and injected it into Jon's arm.

Swiftly then he ran to his own pack, climbed in and fastened the straps. He filled the needle, plunged it into his arm, and pushed home the plunger.
