...Force (with its Wizard anti-missile project) has yet drawn complete plans or even formulated solid concepts for countering ballistic missiles. Far more demanding than the anti-missile itself is development of the fully integrated and highly automatic system required-in the limited time available -to detect an ICBM on its way. track it, predict its trajectory and, at the proper instant, launch an intercept missile with nuclear or thermonuclear warhead. And what is the proper instant? When the missile is still in outer space? Or after it has slowed within the atmosphere? How will the system operate...

...whole new problem confronts the system. The cold fact: it cannot detect missiles. Warns Air Force General Earle E. Partridge, Commander in Chief of NORAD (North American Air Defense): "If the aggressor's weapon is the ICBM, the continent stands today almost as naked as it did in 1946, for I have no radar to detect missiles and no defense against them...

...year) man the isolated DEW line stations, watching luminescent oscilloscopes in darkened rooms. Without the ability to intercept or even to defend themselves (an attack on them would in itself constitute a warning, and thus fulfill the DEW line's purpose), they have a single mission: to detect penetration of the radar fence by unidentified aircraft...

...relays of radar-equipped Navy destroyer escorts and WV2 Super Constellations. These mid-ocean lines stretch from the Aleutians to the mid-Pacific and from Newfoundland to the mid-Atlantic. Backing them up will be chains of underwater "listening" lines, now being built parallel to the coasts, to detect and intercept missile-launching submarines several hundred miles out at sea. In addition, a ground DEW line extension is also under construction across the arc of the Aleutian Islands; other holes are plugged by the Alaskan...

...radioisotope is any element (gold, cobalt, strontium) that has been placed inside a reactor long enough to become radioactive, i.e., to shoot off alpha, beta or gamma rays. Then, when these rays hit another object, their speed or intensity changes; by using Geiger counters and other devices to detect the rays, technicians can learn many filings' about the objects under bombardment. And when isotopes are added to liquids, their flow can easily be followed by Geiger counters...
