...combination of two well-known mechanisms - the robot pilot and the landing beam system designed in 1933 by the Bureau of Air Commerce. As the plane approaches the airport, it leaves the flying beam and picks up two new beams by means of a special cross-shaped antenna on the plane's nose. One of these is a vertical directional beam about five feet wide at the airport. The other is a lateral, curved landing beam which slants down onto the field from one side, almost vertical ten miles out, 60 feet above ground at field edge, 15 feet...
...eggs were found when men from the Fire Station across the road were putting up an antenna for a new radio set. Two were reposing in an ancient nest, another lay broken on a balustrade below, all being 211 feet above the pavement. Ornithology may be permanently expanded as a science by the discovery...
Radioman James W. Hodges, who learned his trade in a Kansas City drug store, was ordered to send out his first SOS signal just four minutes after the Dixie grounded. It was weak because the antenna had blown away, but, as it was repeated, the Navy heard it from Norfolk to Balboa. Tropical Radio heard it from Miami, Radiomarine heard it at West Palm Beach. Out in the raging night other ships heard it, wallowed about on their course. The Texaco tanker Reaper made for the stricken ship. So did United Fruiters Limon and Platano. So did City Service...
...staterooms. When it had spread its stench and filth into the public rooms, a band of women got down on their knees, tried to scrub the floors. Passenger hero turned out to be Henry Treger. National Broadcasting Co. engineer, who climbed the stack to help re-rig the radio antenna. "I never expected to get down safely," he recalled. ''The wind fairly burned...
...shorter radio waves are the closer they seem to have the characteristics of light waves. A parabolic mirror, set behind an antenna, will concentrate radio waves as it would waves of light. Certain English scientists contend that varied pressure gradients in the air, produced by storms, have the same effect on short waves as layers of glass of varied densities have on light. However, the experiments carried on so far by the new station have led to the conclusion that short waves are not as nearly skin to light waves as was believed...
