...fire killed at least five people and injured 1,042. It forced tens of thousands of people to evacuate the buildings. It snarled traffic, stopped train service and knocked TV stations (many had antennas on the roof) off the air. The blast created a 200-ft. by 100-ft. crater. It also forged heroes. A woman in a wheelchair was carried down 66 stories by two friends. A pregnant woman was airlifted from a tower roof...
...their trouble getting to the "blast seat" in the dangerously crumbling underground garage, investigators could not even confirm to their complete satisfaction what had caused the explosion. But its size and intense heat suggested a bomb, as did traces of nitrate found at the edges of the blast crater. Until they could determine otherwise, informed experts assumed that hundreds of pounds of high explosives had been packed into a car or van that was left at a four-level underground parking garage. The garage is situated below the Trade Center plaza and near a station of the PATH commuter subway...
These impacts blasted enough dust into the atmosphere to shroud the entire globe for months on end, blocking sunlight and causing temperatures to plummet. In the cold and dark, plants and animals perished. Compelling evidence of such cataclysms was revealed last summer: scientists confirmed that a giant crater, 176 km (110 miles) across, discovered under the northern tip of Mexico's Yucatan Peninsula was the likely impact point of a huge object, probably a comet, believed to have wiped out the dinosaurs and other forms of life 65 million years...
...convinced that it had been pockmarked not by explosive volcanism, as many geologists then thought, but by asteroid impacts. If that was true, he felt, Earth, a much larger target, must have been heavily bombarded too. For his Ph.D. thesis, Shoemaker prepared a & geologic map of Meteor Crater in Arizona, and in the process confirmed that it had resulted from an impact...
...left in 1982 to launch her own asteroid search, Carolyn, her three children grown, joined Gene. Since then they have been on the alert -- and on the run. Last fall, for example, they went to a conference in Ontario at the site of the 1.8 billion-year-old Sudbury Crater, which is 300 km (188 miles) wide. From there, they flew to Iowa City, Iowa, where Gene examined core samples from the nearby Manson Crater, 35 km (22 miles) across and about 65 million years old and perhaps made by a chunk of the comet that killed the dinosaurs. Then...
