...eyes were fixed on the agent, and especially on the revolver which he carried in an open holster on his belt. As the agent leaned forward to write, Fox grabbed the pistol, got the end under his chin and pulled the trigger. The old bank robber toppled backward, dead...
...illustration of what he called the "Cyclone Look," Dior showed an evening gown that had nearly a score of stiffened folds projected backward, making it look as if the wearer were carrying a huge semicircular balloon on her stern. In his "Winged Line," beruffled evening dresses were boned, wired, lined and otherwise stiffened to flare out as much as two feet in all directions, preventing their wearers from sitting down, dancing within arm's reach of a partner, or standing...
This is mostly because the "propulsive efficiency" of the jets at ordinary speeds is low compared with conventional airplanes. Propeller-driven planes are pushed forward by the reaction from the blast of air forced backward by the prop. When the plane is standing still on the ground with its propeller roaring, all the engine's effort is wasted on merely moving air. None goes into forward motion; the propulsive efficiency is zero. When the plane is in the air, the propulsive efficiency is high. Propellers are designed in such a way that when the plane is flying at full...
...planes are pushed by the reaction of the blast of hot gas shooting out the tail pipe. The present problem is that this blast is speeding much too fast-at about 1,300 m.p.h. Even when the plane is flying at 600 m.p.h., the blast is shooting backward in still air at 700 (1,300 minus 600) m.p.h. The engine is still wasting too much energy merely stirring up the air. To approach the normal propulsive efficiency of a propeller plane, a jet plane would have to fly faster than sound. But one arresting compensation-for the jets-is that...
...While listening to the Democratic convention as continuously as I followed the Republican convention, I observed one striking contrast . . . The Democrats are looking backward on the events of the past, the Republicans are looking forward on the events of the future...
