...Havilland aerodynamicist, has been experimenting with man-powered flight ever since the '40s. Two years ago, after Kremer offered his prize money, Wimpenny organized the Hatfield Man Powered Aircraft Club and designed Puffin. Spars were made from spruce. The plane's framework was covered with a plastic film one three-thousandth of an inch thick. As it took shape in a hangar, Puffin's fuselage grew to 20 ft., its wings spread out for 84 ft. Practicing in the cockpit, Wimpenny took the classic pose of a racing cyclist-body bent forward, hands on a low-mounted...
...other faction. Should the two organizations ever reach a truce, Angola could once more be drenched in blood. The rebels now have automatic weapons and land mines; plastiqueurs trained by Algeria's F.L.N. have begun to infiltrate into Angola, ready to continue the terror with their plastic bombs...
...instruments are the creations of French Sculptor Francois Baschet, 42, whose musical skill is limited to strumming a bar or two on a guitar equipped with an inflatable red plastic doughnut as a sounding board. During a seven-year sabbatical, the thought struck Baschet that all the world's music came from antiques. "For 150 years," says he, "the only instruments that have been invented have been the saxophone, the musical saw and concrete and electronic music. Why?" Baschet began to think of new ways of making noise...
Three minutes after the Thor rocket made its predawn blastoff from Cape Canaveral, a new star flared bright yellow across the dark sky. Tiny by standard star measurements, the man-made balloon of plastic and aluminum was 135 ft. in diameter-tall as a 13-story building, and large enough to be seen by the unaided...
Strong Measure. Republic's proton gyroscope is at present an impractical breadboard model, built mostly of transparent plastic, but even so it works well enough to prove the principle. In a practical instrument, says Milton J. Minneman, head of Republic's gyro project, the coils creating the magnetic field will be attached rigidly to the craft that carries them. As long as the ship or missile follows a perfectly straight course, the protons held in the magnetism will remain electrically quiet. But if the ship turns, their struggle to keep from turning with it will generate an electric...
