Some space observers believe that the tests relate to an offensive orbiting weapons system. Other scientists have noted that the payloads seem to be brought back to earth within a closely limited area some 600 miles northeast of Tyuratam, where radar and other sensor devices can obtain a wide variety of re-entry data. Pursuing this line of reasoning, their best guess is that the Russian test flights are part of an effort to develop either maneuverable warheads that can avoid anti-ballistic missiles or manned vehicles that can withstand the 23,400 m.p.h. re-entry speeds of a lunar...
...trigger an audio-visual alarm and possibly give the pilots a harmless electric shock. In today's jets, the warning would come 60 seconds prior to possible collision, when the aircraft were about 20 miles apart. Twenty seconds later, after electronic analysis of courses, speeds and altitudes, the sensor-computers would signal the best possible collision-avoidance maneuver each pilot should execute, such as "stop turn" or "stop climb...
With this system, the passenger himself is the only one to handle his baggage. He stows it aboard a kiddy-car-sized plastic cart and picks up a claim ticket. At the check-in counter, a clerk inserts the ticket into a sensor, sending cart and luggage along a track onto the proper airplane. At his destination, the passenger again inserts his ticket into a slot, whereupon the laden cart obediently trundles to his side. Estimated average time for the loading or unloading operation: three minutes...
Kittenlike Proportions. After months of experimentation, a group led by North American Electronics Engineer Edward Flint devised a compact infrared sensor that can be mounted atop a plane. While scanning 45° to either side of the aircraft's flight path, the sensor can detect temperature variations as small as a fraction of a degree Fahrenheit in atmospheric carbon dioxide at a range of from 24 to 48 miles. These variations register on three side-by-side cockpit gauges that show the pilot whether a temperature gradient lies directly ahead or 45° to the left or right...
...their advanced Molniya communications satellite, which in synchronous orbit over Siberia can relay color TV between Moscow and Vladivostok. And Molniya satellites have relayed long-distance phone calls and taken weather pictures of the earth's cloud cover. Molniya was cluttered with so many unlabeled antennas and sensor systems that scientists figured that the satellite was also capable of serving a "spy in the sky" function over...
