...island near a small fishing village on the northwestern Zamora coast, just 40 miles from the Salvadoran border, uncovered the remains of what appears to have been a depot for smuggling arms to guerrillas in El Salvador, including a Sandinista army banner, rifle shell casings and a radio antenna. The discovery buttressed U.S. claims that Nicaragua routinely supplies the Salvadoran rebels by boat across the Gulf of Fonseca...
...conventional skydiving establishment, which regards them as airborne Hell's Angels, mostly because the trespassing often involved in fixed-object jumping (but not the leaps themselves, Boenish quickly points out) is illegal. One of the great early jumps, from which springs the present fad of BASE (for Buildings, Antenna towers, Spans and Earth) jumping was made in 1970 by Rick Sylvester. He skied off of Yosemite's 7,569-ft. El Capitan, popped a chute and floated down to the meadow below. Some 120 bandit jumps followed, and finally, in 1980, the park grudgingly began handing out permits...
...points serenely skyward from a ridge dotted with apple orchards, the 84-ft.-wide dish appears to be just another space-age antenna. But last week, the Harvard radio telescope, 30 miles northwest of Boston, became the center of a champagne inaugural and worldwide scientific attention. As colleagues and reporters clustered around him inside the observatory's control room, Harvard Physicist Paul Horowitz tapped a few keys on a computer terminal. A minute or so later, a jumble of jagged lines flickered onto a video monitor. They represented the random squawks and beeps of the universe that had just...
...range of radio frequencies that might be used for transmissions. Horowitz, who caught the SETI (Search for Extraterrestrial Intelligence) bug after Cornell's Sagan lectured on the subject at Harvard, decided to improve the odds. He developed a compact multichannel receiver that can be hooked to a large antenna and can listen to 131,072 closely spaced channels simultaneously...
Meanwhile, FBI explosives experts concluded that the black box with the antenna clutched by Mayer was a miniature radio transmitter fully capable of detonating an explosion. Although the blast from 1,000 Ibs. of TNT would probably have only scarred the marble face of the monument, it could have sent out a concussive wave creating an arc of destruction from the White House to the Potomac. Seven nearby museums were evacuated, and a White House luncheon given by President Reagan was moved out of the room facing the monument...
