...designers and test pilots pushed their planes up toward the speed of sound, the danger they feared most was the beating they took in the "transsonic zone." When an airplane is moving close to sonic speed, shock waves'(powerful sound waves) form on its wings and control surfaces. They come and go, shift irregularly and sometimes exert enormous forces on the plane's structure. Many early airplanes that trespassed too far into the transsonic range were destroyed by galloping shock waves. The remedy is now understood: thinner wings and tail surfaces, and a quick passage through the danger...
...Alexander last night denied Dr. Schreiber's counter-charge that the move to remove him from his post is "Communist-inspired." He termed the German "a special pet of the Russians" who only fied the Soviet zone of Germany when the Western powers declared an amnesty on Nazi war criminals...

...into snakelike, horizontal waves whose southern lobes sometimes reach the tropics. On the western sides of the waves the wind aloft blows toward the southeast, carrying with it masses of cold northern air. On the eastern sides the wind blows toward the northeast, carrying tropical air into the temperate zone. When two such dissimilar air masses clash, they produce the familiar "cold front" or "warm front" that marches across oceans and continents...
