Visual Dividend. Aerodynamicist Cahn admits that he does not have the answer to one objection raised to his paper at the A.I.A.A. meeting: the creation of a sufficiently strong electrical field might require too much power to be economical. But he points out that there would be less drag or air friction on a charged SST, reducing the power necessary to fly it at a given speed and altitude. He suggests that only further tests with larger models and wind tunnels-now being considered by Northrop, Boeing and NASA-can determine if the system is practical...

Designed by Swiss-born Aerodynamicist Werner Pfenninger, the intricate tracery promises to be the first practical answer to a problem that is as old as airplanes: how to smooth out the turbulent air that burbles along the surface of a moving wing. Every airplane wastes some of its power overcoming the drag of that churning air, but not until modern planes moved up toward jet speeds did the drag demand a remedy. Slow planes can live with their own slight turbulence; a fast ship becomes a fuel-gulping monster as it fights the furious air waves that swirl and eddy...
...necessarily, Aerodynamicist Robert Brodsky told the Institute of the Aerospace Sciences in Manhattan last week. Spaceships, like ocean liners, said Dr. Brodsky, can carry lifeboats. When stowed on board, a Brodsky-designed lifeboat will be a cylinder of strong, heat-resistant plastic up to 1 yd. in diameter, 11 ft. long, and weighing about 1,000 lbs. Inside will be an airtight capsule large enough to hold one man lying face down. A crewman bailing out will crawl into the capsule and detach the lifeboat from the spaceship. As soon as it is clear, nitrogen gas from a pressure vessel...
