Wonders to Come. As liquid or vapor, silicones are sprayed on all sorts of materials to make them waterproof; they form a thin, invisible film which does not change the feel of the material. As oil or grease, they make ideal lubricants. As plastics, they are extremely tough. Some silicone wonders promised by engineers...
...reconnaissance pilot was astonished at finding a V-2 zooming toward his plane over Europe, close enough for him to try for a picture. But the whooshing rocket was too quick for his camera and his plates showed only V-2's trail of vapor-"like a Bronx cheer in smoke...
...front (see cut, right). Behind it is a gas-combustion chamber. At the takeoff, the gas is ignited. When the bomb is in motion, air rushing into the jets opens them, passes into the combustion chamber, sets off an explosion which closes the jets and expels the expanding vapors from the rear end, giving the bomb a forward push. As the vapor escapes, air opens the jets again and the process is repeated, 45 times a second, to give the machine an almost continuous thrust...
...doldrums," a generally calm region in the equatorial Atlantic between the Cape Verde Islands and the West Indies, waves of heated air molecules begin to rise from the warm sea. As cooler molecules rush in from the sides to take their place, and the rising air, saturated with ocean vapor, cools off in the upper atmosphere, the air currents move faster & faster. Soon the growing whirlwind, given a counterclockwise spiraling motion by the earth's rotation (it is clockwise in the Southern hemisphere), resembles a vast phonograph record, with a hollow core, the vortex or "eye" of the storm...
...magnificent close-up of the landing gear as it retracts, flattening like the feet of a bird in flight, and disclosing the countryside. Technicolor comes fully into its own when the Belle and the planes of her formation climb steadily over the North Sea, striating the sky with vapor trails, and when (over Germany) the flak begins to pop its thick corn. Shots which are merely powerful in black-&-white become overpoweringly real and immediate in Technicolor. To the layman the actual bombing, for all its excitement, is just an uncommunicative, tremendous tower of smudge. And the trip home, through...
