The ship was a tremendous flying wing. A standard commercial job. Empty--passengers, even crewmen, were never subjected to the brutal accelerations regularly used by unmanned carriers. Phryges scanned the panel. Tiny motors were pulling tapes through the controllers. Every light showed green. Everything was set. Donning a water-proof coverall, he slid through a flexible valve into his acceleration-tank and waited. A siren yelled briefly. Black night turned blinding white as the harnessed energies of the atom were released. For five and six-tenths seconds the sharp, hard, beryllium-bronze leading edge of the back-sweeping V sliced its way through ever-thinning air. The vessel seemed to pause momentarily; paused and bucked viciously. She shuddered and shivered, tried to tear herself into shreds and chunks; but Phryges in his tank was unconcerned. Earlier, weaker ships went to pieces against the solid-seeming wall of atmospheric incompressibility at the velocity of sound; but this one was built solidly enough, and powered to hit that wall hard enough, to go through unharmed. The hellish vibration ceased; the fantastic violence of the drive subsided to a mere shove; Phryges knew that the vessel had leveled off at its cruising speed of two thousand miles per hour. He emerged, spilling the least possible amount of water upon the polished steel floor. He took off his coverall and stuffed it back through the valve into the tank. He mopped and polished the floor with towels, which likewise went into the tank. He drew on a pair of soft gloves and, by manual control, jettisoned the acceleration tank and all the apparatus which had made that unloading possible. This junk would fall into the ocean; would sink; would never be found. He examined the compartment and the hatch minutely. No scratches, no scars, no mars; no tell-tale marks or prints of any kind. Let the Norskies search. So far, so good. Back toward the trailing edge then, to a small escape-hatch beside which was fastened a dull black ball. The anchoring devices went out first. He gasped as the air rushed out into near-vacuum, but he had been trained to take sudden and violent fluctuations in pressure. He rolled the ball out upon the hatch, where he opened it; two hinged hemispheres, each heavily padded with molded composition resembling sponge rubber. It seemed incredible that a man as big as Phryges, especially when wearing a parachute, could be crammed into a space so small; but that lining had been molded to fit.
