As he ran toward the control room, Hargraves heard the ship begin to radiate a new tempo of sound. The siren was dying into silence, its warning task finished. Other sounds were taking its place. From the engine room in the stern was coming a spiteful hiss, like steam escaping under great pressure from a tiny vent valve. That was the twin atomics, loading up, building up the inconceivable pressures they would feed to the Kruchek drivers. A slight rumble went through the ship, a rumble seemingly radiated from every molecule, from every atom, in the vessel. It _was_ radiated from every molecule! That rumble came from the Kruchek drivers warping the ship in response to the controls on the bridge. Bill Kruchek's going-faster-than-hell engines, engineers called them. A fellow by the name of Bill Kruchek had invented them. When Bill Krucheck's going-faster-than-hell drivers dug their toes into the lattice of space and put brawny shoulders behind every molecule within the field they generated, a ship within that field went faster than light. The Kruchek drivers, given the juice they needed in such tremendous quantities, took you from hell to yonder in a mighty hurry. They had been idling, drifting the ship slowly in toward the planet. Now, in response to an impulse from Nielson on the bridge, they grumbled, and hunching mighty shoulders for the load, prepared to hurl the ship away from the planet. Hargraves could feel the vessel surge in response to the speed. Then there was a distant thud, and he could feel the surge no longer. The anti-accelerators had been cut in, neutralizing the effect of inertia. Shoving open a heavy door, Hargraves was in the control room. A glance showed him Nielson on the bridge. Leaning over, his fingers on the bank of buttons that controlled the ship, he was peering through the heavy quartzite observation port at something approaching from the right. Beside him, on his right, a man was standing ready at the radio panel. And to the left of the bridge two men had already jerked the covers from the negatron and were standing ready beside it. * * * * * Ron Val leaped past Hargraves, dived for a seat on the negatron. That was his post. He had been chosen for it because of his familiarity with optical instruments. Along the top of the negatron was a sighting telescope. Ron Val looked once to see where the man on the bridge was looking, then his fingers flew to the adjusting levers of the telescope. The negatron swung around to the right, centered on something there. "Ready," Ron Val said, not taking his eyes from the 'scope. "Hold your fire," Hargraves ordered.
