...Smoke Signal...
Lazing alongside were three French air force "Mistral" jets. One waggled its wings as if to signal to the Ilyushin. The Russian pilot stolidly pursued his course, and for eight minutes the jets merely kept pace. Then, suddenly, one of them whooshed ahead, turned and opened fire in the Russian plane's path. "International banditry," howled Moscow's pro test to France. The Ilyushin had been 82 miles off the Algerian coast at the time of the incident, declared the Russians. It had cleared properly with Algiers control, cried Moscow: the attack had been entirely unprovoked...
Until recently, most scientists assumed that radar signals would travel only in a straight line. But, working independently, both Gallet (rhymes with ballet) and Professor Henry G. Booker of Cornell University concluded that the skies over the earth were full of radar "pipes"-masses of electrons clustered in arching sheets along the curving lines of the earth's magnetic field and extending out into the exosphere, the near empty area of space more than 400 miles above the earth. If a radar signal were beamed into one end of such a "pipe," Gallet and Booker reasoned, the gently bending...
Tilting a 100-kw. high-frequency radar transmitter 71° into the night sky near Washington, D.C. last April 22, Gallet aimed a radar beam at what he believed to be a pipe that would carry the signal to a point in the South Pacific Ocean just off the southern tip of South America. Two-tenths of a second later, an echo came bounding back-after a round trip of 37,000 miles...
...high was recorded last week for the third week in a row. Prices of unlisted industrial stocks rose to the highest point since the National Quotation Bureau began keeping figures in 1948. To the nation's 4,000 dealers in unlisted stocks, the rise was a cheering signal that investors are moving in force into the world's largest securities market, where prices are quoted daily on more than 5,000 stocks, more than are listed on all the U.S. exchanges together...
