aisle, leaping for the pilot's compartment. He had no plan; he wasn't even thinking. In the background of his mind he knew the panic he had created; he could see it reflected in the face of the woman in the front seat, in the wide, suddenly terror-stricken eyes of the man at her side. But what he was going to do when he reached the closed door that was his goal, he did not know. There were screams and hoarse commands. From the rear, the stewardess shouted for him not to go beyond the door. Griffin reached it, whirled and faced the length of the plane, a snarl on his lips, and the .38 in his hand, a small-barreled threat of death to whoever was fool enough to attempt to stop him. And there was one who was going to be a fool. Whether Jenkins was just dazed by the last blow, or whether he really thought he could stop the other, is a matter of conjecture. But he rose to his feet and started forward in a stumbling run. "Come on, copper," Griffin grunted, a terrible smile of anticipation on his lips. "I been wantin' to knock you off."

But louder than the pistol's sound, was the sound from without the plane. It was as if all the fury of hell had exploded out there. The plane became a straw licked upward and outward, sucked downward and inward, in some vortex of sound and fury which was completely unrecognizable. It was as if some external force was venting its spleen on the craft. In the space of split seconds, in the time a picture forms in a mind, the plane and all its occupants lost their meaning. There was a great rending sound and, following, the disintegration of the great ship into space. Hale Jenkins felt himself
