Abdul braked. Chimaeras are extraordinarily maneuverable creatures. Abdul seemed practically to stop short in mid-air. The roe almost crashed into him, its cavernous beak widening in awful menace.
Actually, the roc’s beak was no more than twenty feet away when Tony squeezed hard on his improvised bomb, felt the glass crunch—and heaved the cloth-wrapped missile into the gaping throat. It was an excellent shot. He saw the little object go flying down the two-yard, open gullet to its maw.
“Roger!” roared Tony. “Step on it! Move!”
Then he felt as if his neck would snap off. Abdul took evasive action. It began with an outside loop that made the safety belt creak hideously, was followed by a wing-over at the bottom, and then continued as a power dive in which the wind went pouring into Tony’s open mouth until he felt as if he were being forcibly inflated.
But even then he looked back.
The roc was motionless, as if paralyzed by some awful shock. But the paralysis lasted only for seconds. Suddenly the already huge form expanded still more. It struggled convulsively. It sneezed. In its struggling it had not stayed on an even keel. The sneeze had all the propulsive effect of a high-temperature jet. It kicked the suddenly shapeless object violently higher. It writhed. It struggled again, very horribly. It ceased to be a bird, it was impossible to say what it was! Another convulsion even more violent than the first. The almost amoeboid object shot higher—it had pseudopods now, which appeared at random and flailed aimlessly but with terrific force. A second convulsive sneeze ejected so huge a volume of air with such violence that the djinn was shot up a good five thousand feet.
Es-Souk was maddened, now, with the knowledge of his doom. He went into lunatic gyrations which turned into flight straight upward. But he flew now not by wings or any motion of any members, but by the lightning-swift protrusion of a threadlike pseudopod far ahead and the equally lightning-like flowing of all his substance up to and into it, and the instant repetition of the process.
Even huge as he now was, he rose so swiftly as to dwindle as Tony watched. At ten miles altitude there was a convulsive sidewise jerking of the climbing thing. Another sneeze. He continued to shoot frantically skyward. Twenty miles up… he was probably a quarter-mile across, but he became a speck which could barely be distinguished.
Then he blew up. He must have been fifty miles high, at least. He was in the upper troposphere. And he must have weighed several hundred pounds. Perhaps not all his substance disintegrated. Even human atomic bombs do not detonate with one hundred percent conversion of their mass into free energy. Es-Souk’s efficiency as a bomb was probably less than that of purified U235 or plutonium. But the flare was colossal. There was a sensation of momentary, terrific heat. No sound, of course. The explosion took place where the air was too thin to carry sound. For the same reason there was no concussion wave. But the flash of Es-Souk’s detonation was several times brighter than the sun and a dozen times the sun’s diameter.
Minutes later, Abdul came rather heavily to a landing on the desert. Tony dismounted. Abdul seemed to dissolve suddenly and run together, without any intermediate state, to restore the djinn to his short, swart, human form, with the turban atop his head. He was trembling.
