...departure is the 90-ft. bipod mast. Stretching 20% taller than an ordinary mast on a yacht this size, it looks something like a seven-story wishbone straddling the boat. Made of lightweight carbon-fiber, it replaces the familiar -- and bulky -- pole-and-support system midships, for a better airflow onto the mainsail. The height of the newly designed structure allows the boat to carry 25% to 30% more sail for greater speed. Moreover, it is movable and hinged at the deck so that the entire assembly can be raised and lowered...
...jettison the escape-hatch cover, then exit one by one. If the rocket system is in place, each astronaut will be yanked from the ship with 2,000 lbs. of thrust. Otherwise, they will hook onto the telescoping pole, which will extend through the door, and let gravity and airflow pull them down and out of harm's way. Both the astronauts and NASA favor the pole: it avoids the danger of rocket fuel in the cabin and takes up less space. Of course, entering a high-speed stream of air blowing by at extreme altitudes poses many perils...
...North. The plane, loaded with a full 39,128 lbs. of jet fuel and 6,000 lbs. of baggage, hurtled farther than normal down the runway and rose less than 50 feet before plunging. In the cockpit, a computer- generated voice repeated the words "stall . . . stall," indicating that the airflow over the wings was no longer sufficient to lift the plane; the jet was falling, not flying. Traveling at about 215 m.p.h., the plane knocked a jagged piece off the roof of a rental-car building and then ricocheted off the embankment of an access road to Interstate 94. Flight...
...haunted by a peculiar American dream from the days when model-airplane kits were still mostly balsa. A 1929 high-wing monoplane, bravely lacquered in sky blue and wasp yellow, hangs from the ceiling, almost low enough for the grown visitor to touch its spats. Nearby sits the Chrysler Airflow -- not, alas, the classic 1934 model with the "waterfall" radiator, but still modernity on wheels, squinty windshield, fairings and all. Between them are such icons as the 1936 Sears-Roebuck Waterwitch outboard, offering its owner some whiff of the thrill associated with Henry Dreyfuss's bullet-nosed locomotives or Norman...
...magnetic fields needed for fusion reactors and designing heat shields for future space probes. Meanwhile, demands for ever faster computers are coming from researchers in nearly every discipline of science and engineering, from astrophysics to automobile design. Using more powerful supercomputers, aircraft manufacturers will be able to simulate the airflow around an entire airplane, simplifying their design task. Similarly, energy companies will be able to find more oil and meteorologists to make more accurate forecasts, eventually providing earlier warnings of impending storms like last month's killer tornadoes...
