...didn't think the U.S. would be able to give candidates a weekend at a country manor, but "I think the idea of keeping the applicant under observation for two or three days, of permitting him to demonstrate his personality and capacity for leadership, is a very practical approach...
...dozen a week. By last week, Lee Skirt had upped production more than 200%-1,250 dozen a week. U.S. department stores were taking the entire output. Retailing mostly at $1.99 and $2.95, the company's all-wool and rayon skirts are a bargain that few competitors can approach...
...ideal training," he says, "would combine the kind of technical skill you learn at the Boston Museum School [how to paint what you see] with the more ab stract approach [painting as a language of its own] that Black Mountain provides...
...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 some day they may fly even that fast...
This is why air designers approach the speed of sound with infinite trepidation. The most troublesome speed begins just below Mach I. When a wing is moving at, say, Mach .80, the air passing over it has to hurry to get around its bulge. If, in doing this, it reaches Mach I, violent things may happen. The smooth airflow breaks into turbulence as hard shock waves jump around on the wing (see cut). The drag increases enormously; the wing's lift drops. The buffeting from the irregular airflow may be strong enough to tear the wing apart. This sometimes...
