Also the concussion wave, or the explosion front, or flying fragments, or something, struck the two loose bombs, so that they too exploded and added their contribution to the already stupendous concentration of force. They were not close enough to the flitter to wreck it of themselves, but they were close enough so that they didn't do her--or her pilot--a bit of good. The first terrific wave buffeted the flyer while Cloud's right hand was in the air, shooting across the panel to turn on the Berg. The impact jerked the arm downward and sidewise, both bones of the forearm snapping as it struck the ledge. The second one, an instant later, broke his left leg. Then the debris began to arrive. Chunks of solid or semi-molten rock slammed against the hull, knocking off wings and control-surfaces. Gobs of viscous slag slapped it liquidly, freezing into and clogging up jets and orifices. The little ship was hurled hither and yon, in the grip of forces she could no more resist than can the floating leaf resist the waters of a cataract. And Cloud's brain was as addled as an egg by the vicious concussions which were hitting him from so many different directions and so nearly all at once. Nevertheless, with his one arm and his one leg and the few cells of his brain that were still at work, the physicist was still in the fight. By sheer force of will and nerve he forced his left hand across the gyrating key-bank to the Bergenholm switch. He snapped it, and in the instant of its closing a vast, calm peace descended, blanket-like. For, fortunately, the Berg still worked; the flitter and all her contents and appurtenances were inertialess. Nothing material could buffet her or hurt her now; she would waft effortlessly away from a feather's lightest possible touch. Cloud wanted to faint then, but he didn't--quite. Instead, foggily, he tried to look back at the crater. Nine-tenths of his visiplates were out of commission, but he finally got a view. Good--it was out. He wasn't surprised; he had been quite confident that it would be. It wasn't scattered around, either. It _couldn't_ be, for his only possibility of smearing the shot was on the upper side, not the lower. * * * * * His next effort was to locate the secondary observatory, where he had to land, and in that too he was successful. He had enough intelligence left to realize that, with practically all of his jets clogged and his wings and tail shot off, he couldn't land his little vessel inert. Therefore he would have to land her free. And by dint of light and extremely unorthodox use of what jets he had left in usable shape he did land her free, almost within the limits of the observatory's field; and having landed, he inerted her.
