But it wasn't meant as a way to fly from one place to another on Earth. It was the first booster stage of a three-stage rocket aimed at outer space. It looked rather like--well--if a swarm of bumblebees clung fiercely to a wire-gauze cage in which lay a silver minnow wrapped in match-sticks; and if the bees buzzed furiously and lifted it in a straining, clumsy, and altogether unreasonable manner; and if the appearance and the noise together were multiplied a good many thousands of times--why--it would present a great similarity to the take-off of the spaceship under Joe's command. Nothing like it could be graceful or neatly controllable or even very speedy in the thick atmosphere near the ground. But higher, it would be another matter. It _was_ another matter. Once clear of the Shed, and with flat, sere desert ahead to the very horizon, Joe threw on full power to the pushpot motors. The clumsy-seeming aggregation of grotesque objects began to climb. Ungainly it was, and clumsy it was, but it went upward at a rate a jet-fighter might have trouble matching. It wobbled, and it swung around and around, and it tipped crazily, the whole aggregation of jet motors and cage and burden of spaceship as a unit. But it rose! The ground dropped so swiftly that even the Shed seemed to shrivel like a pricked balloon. The horizon retreated as if a carpet were hastily unrolled by magic. The barometric pressure needles turned. "Communications says our rate-of-climb is 4,000 feet a minute and going up fast," Mike announced. "It's five.... We're at 17,000 feet ... 18,000. We should get some eastward velocity at 32,000 feet. Our height is now 21,000 feet...." There was no change in the feel of things inside the ship, of course. Sealed against the vacuum of space, barometric pressure outside made no difference. Height had no effect on the air inside the ship. At 25,000 feet the Chief said suddenly: "We're pointed due east, Joe. Freeze it?" "Right," said Joe. "Freeze it." The Chief threw a lever. The gyros were running at full operating speed. By engaging them, the Chief had all their stored-up kinetic energy available to resist any change of direction the pushpots might produce by minor variations in their thrusts. Haney brooded over the reports from the individual engines outside. He made minute adjustments to keep them balanced. Mike uttered curt comments into the communicator from time to time. At 33,000 feet there was a momentary sensation as if the ship were tilted sharply. It wasn't. The instruments denied any change from level rise. The upward-soaring complex of flying things had simply risen into a jet-stream, one of those wildly rushing wind-floods of the upper atmosphere. "Eastern velocity four hundred," said Mike from the communicator. "Now four-twenty-five.... Four-forty."
