Tom slid under the controls of the sleek ship, and while Astro, Sid, and Kit went below to the power deck, he began to figure their speed at a D-30 rate. He used a pencil at first, scribbling on a piece of paper, but the answer he reached was so fabulous, he put the ship on automatic gyro control and climbed to the radar deck where he checked the figures on the electronic calculator.
