A wrecking ball damaged a number of vehicles in the US state of Pennsylvania after it broke loose from its crane and rolled down the street.
Three people were taken to hospital after the 680kg ball smashed its way down North Main Street in Meadville like a giant bowling ball.
The ball finally stopped rolling when it ran into the back of a Ford Taurus.
"All of a sudden the back windshield exploded and I hit the car in front of me," one witness told the Associated Press.
"I thought a car hit the back of me, but when I turned around, I couldn't see anything."
