 NEW YORK (AP) - They are part of New York's skyline: hundreds of spindly construction cranes like the one that toppled over the weekend, pulverizing parts of a city block below and killing seven people. As the machines work furiously amid a supercharged building boom, experts say it's always a risk.
Operating cranes in a city of 8.2 million people where apartments and offices are stacked so closely and on top of one another is especially tricky.
"Because of the tightness of a construction site in New York City, there's always the problem of having less space, and also there's the problem that if anything does go wrong, there are a lot of people at risk," said Gene Corley, a structural engineer.
