Mashable reports on the collapse of a Brooklyn building that had been photographed by Google street view. The pic clearly shows a crack in the building.
In the late 1970s, after the collapse of the Hartford Civic Center coliseum roof, someone examining pre-construction photos found bends in the steel piled up awaiting use. No one noticed it until after the investigation began. Google and the many other purveyors of information make it easier to track back problems. The question is whether there's a way to find problems like this before an accident occurs (And this assumes the crack is a sign of impending problems.)
