...ingenious experiments by other scientists anxious to test its validity. Although no experimental results have contradicted the theory, they have not been precise enough to rule out opposing theories that differ in small but significant details. Now a new technique has been used to check out Einstein: interplanetary radar. Preliminary radar tests also have failed to find a flaw in general relativity, a scientist from Massachusetts Institute of Technology's Lincoln Laboratory announced last week, and radar soon should provide results accurate enough to help confirm the theory-or to seriously undermine...
...first that the equipment "consisted in essence" of normal radio receivers that gave the ship "added capacity" to detect indications of possible attack. In testimony released at week's end, however, he admitted that, far from being routine, the electronic gear was designed to somehow "trigger" North Vietnamese radar so that the U.S. would know the frequencies of Northern radar installations. Then, in an amazing turnabout, the Navy disputed its chief, insisting that the equipment was indeed only standard gear...
When the blips were about three miles off, Turner Joy began firing, using her radar as guide, since nothing could be seen. Maddox followed suit-though her radar showed no target at all. Says Lieut. Raymond Connell, in charge of Maddox's guns: "I recall we were hopping around up there, trying to figure out what they [Turner Joy] were shooting at. We fired a lot of rounds, but it was strictly a defensive tactic." It could also have been a malfunction on the radar screen. Aircraft from the carriers Ticonderoga and Constellation were overhead by this time...
...change course while launching or landing aircraft and thus maybe dump a few planes into the sea. In the air, bombers of the Soviet navy^s 750-plane, land-based air force continually test to see how close they can approach U.S. carriers before they are detected by radar and intercepted by the carrier's own planes. Their aim is to avoid being caught until they have got within 100 miles of the carrier. Reason: from that range, the Russians would have a good chance of scoring a hit with their air-to-ship missiles before the carrier could scramble...
...other places in I Corps and that Hanoi might even try to send its handful of Russian IL-28 jet bombers as far south as Saigon. For several months, Giap is known to have been considering the use of warplanes in the south. Despite the huge array of U.S. radar, missiles and interceptors stationed to defeat any such attempt, the experts feel that suicide missions or low-flying intruders might just succeed in dropping their bombs...
