The crew of that dirigible of death, Chris discovered, had not had a chance. White-clad bodies lay sprawled throughout the cabin which contained the mechanism of the plane rack, stricken down silently at their posts. There was no life, no sound save the booming of the motors and the whip of the wind screaming past the uncontrolled air titan.
But he did not pause there. He did not know what he was grappling with—it seemed black magic—but he darted to a ladder which angled up from the lowermost entrance cabin to the cat-walk that stretched from the nose to the stern of the ship. If any infernal contrivance had been planted aboard, it would be in the most vital spot.
Heart pumping from the artificial air he was breathing and from the consciousness that each second might well be his last, he sprinted along the interior gangway. Above was the vasty gloom of the gas bags and the interweaving latticework of the supporting girders; the drum of power-car motors and the strained creakings of cables and supports echoed weirdly throughout. Outside was the sun and the sea and the clean air, but this realm of mammoth shapes and dimness seemed apart from the world. Once he stumbled against something soft and yielding—a body flung down there in death, fingers at its throat. And there were other white-clad figures, grimly marking off the length of the cat-walk....
Chris's nerves were raw and his face sopping with sweat beneath its mask when suddenly he stopped at sight of something that lay on the cat-walk, with the main fuel tanks on the girders just above it and the entrance to the control car just below.
It was a black box, perhaps two feet square and a foot in depth, made of dull metal that did not reflect the rays of the light bulb placed at the head of the ladder leading down in the control car. There were three curious little dials on its face, and the trembling finger of each one was mounting.
It had been strategically placed. An explosion at that point would rip open the fuel tanks, split the largest gas bag, wreak havoc on an intricate cluster of main girders, and destroy the control car with its mechanism.
"No wonder the ZX-2 crashed!" Chris muttered.
Then his hands swept down. The next instant he was hugging the thing tight to his chest and stumbling down into the control car, hearing only a high-pitched, impatient whine that was coming from the box as the fingers of its dials crept slowly upward.
The ZX-1 was wavering wildly as her rudders flopped from side to side, and with every swing the bodies that lay in her control car, strangled by gas, stirred slightly. The gray-haired commander was stretched there, one arm limply rolling as his ship, which had gone so suddenly from him, rolled. Subordinate officers were tumbled around him. Death rode the control car.
