"Ready to take off, sir," he said.

"Roger. Fire away."

He made a quick survey of the sky to be sure no other aircraft were in the vicinity. There was no control tower with which to check out. Now! He made himself relax a little and pushed the throttle to take-off position.

Fast acceleration snapped him back against the seat. The jet began to wander a little and he corrected automatically, and almost overcorrected! With infinite care he straightened out again, just as the plane was air-borne. Eyes riveted on the horizon, he felt for the switch that pulled up the landing gear and felt the plane spurt ahead as the drag of wheels and struts was removed.

Lipton's voice came through the phones, relaxed and a little amused. "No need to treat this bucket of bolts like a baby, Rick. You've got power to burn. Go, man! Make like a bird!"

Rick had to grin. He was flying automatically, as he flew his own Sky Wagon. But Lipton was right. This was a jet, not a low-powered sports plane. Suddenly exuberant he cracked the throttle and stood the jet on its tail. It climbed vertically, an amazing sensation for Rick. Power to burn!

The altimeter read ten thousand feet. He asked, "Can I sort of toss it around a little?"

Lipton chuckled. "You're flying, and I have a strong stomach."

Rick kicked the plane over and let it drop, saw the Nevada mountains rushing up to meet him. He leveled off and pulled into a tight turn, much as he might turn the Sky Wagon. G forces slammed him into the bucket seat and the world went gray as blood drained from his head.

"Let up," Lipton snapped.
