One, louder than the rest, rasped an order. And again Chet felt the hands relax; once more he was falling, down--down--and still down--until he knew that his velocity of fall meant an impact he could never survive. And, curiously, as he fell, his mind was entirely unconcerned with his own fate. For himself, he had accepted death. But he saw for what seemed like hours a vision of a familiar control room and an Irish pilot who sat by the controls. He was looking sharply ahead, he was checking speed, he was landing softly--safely--on a familiar field of Earth.... That passed; and, following, came a feeling of regret, a deep hurt and a rage at his own inability to be of help. For, above him, through the luminous air, he saw another body falling, and he knew that the girl, too, had been thrown to the same fate. * * * * * Those eyes of blue had locked with his for but a few brief seconds. Who she was--what she was--he had no way of knowing. But in that instant of mental meeting there had passed a flash between the two that had burned deeply into Chet's real and hidden self. Chet, himself, had he been in laughing mood, might have smiled at the idea of affection being born in that brief time. Yet he might have asked instead how long was needed to bridge the sharp gap of a radio-power transmitter; how much time was needed for anode and cathode each to recognize the other. Something of this was passing in confusion through his mind while his more conscious faculties were tensing his body for the fatal impact he knew must come. Without thinking the thought in words he knew that the luminous walls had receded. They were more distant now; their glow came to him from far above, and, as his falling body turned again and again in air, he saw that below him was nothing but a vast emptiness filled with luminous vapors that swirled and writhed. Then the last gleam of lighted walls faded; he was falling at terrific speed through a black tempest whose winds tore and screamed about him. * * * * * It was his own falling speed that made these winds; there remained with him enough of reasoning power to realize this. And he waited, and marveled that he could fall so tremendous a distance. First had been the great shaft down which he had plunged; then, as it widened, had come this greater void. The crater of Hercules must have opened, into a vast shell or a cavern of incredible depth. The winged things of the Moon knew of it; they had cast him to his death--him and the girl. Her slowly turning body was not far away; it was as if they two hung suspended in air, while frightful blasts of whatever gas filled this space whipped and shrieked past and wrapped them round with a terrific pressure. And then the tempest ceased. Slowly the blasts diminished; the pressure relaxed; gradually the sense of falling passed away, and with this there came a glimpse of light.
