Alex Habay was in his Ford Taurus, stopped at a traffic light in downtown Meadville, Crawford County, yesterday morning, thinking about nothing, idly listening to a radio commercial while on his way to his summer job at the YMCA. That’s when a 1,500-pound wrecking ball smashed into the rear of his car.

Meadville police said the episode began around 9:45 a.m. about 3,600 feet away, near Allegheny College’s Pelletier Library, where a crane was demolishing part of the building. That’s where the cable holding the 3-foot-diameter wrecking ball snapped, starting its downhill tumble from the college to the town.

As it gained momentum, the wrecking ball rumbled from the campus along North Main Street, pinballing back and forth across the street, hitting nine parked cars and damaging curbs with each impact. By the time it reached Mr. Habay’s car at North Main and Randolph streets, it had gained enough momentum to crush the trunk into the back seat, showering Mr. Habay with glass and pushing his car into the two cars in front of him. The fourth car in line was a Meadville police cruiser.
