"Control deck to power deck ... energize the cooling pumps!"
"Cooling pumps, aye," came from Astro.
The giant ship began to shudder as the mighty pumps on the power deck started their build.
Tom strapped himself into the pilot's seat and began checking the dials in front of him. Satisfied, he fastened his eyes on the sweep hand of the time clock. Above his head, the teleceiver screen brought him a clear picture of the Academy spaceport. He watched the giant cruisers take to the air one by one and rocket into the vastness of space.
The clock hand reached the ten-second mark.
"Stand by to raise ship!" Tom called into the intercom. The red hand moved steadily, inexorably. Tom reached for the master switch.
"Blast off minus—five—four—three—two—one—zero!"
Tom threw the switch.
The great ship hovered above the ground for a few moments. Then it heaved itself skyward, faster and ever faster, pushing the Earthmen deep into their acceleration cushions.
Reaching free-fall space, Tom flipped on the artificial-gravity generator. He felt its pull on his body, quickly checked all the instruments and turned to Captain Strong.
