Yikes: Shattered Window Pane Rains Glass On Street Below

This is a video from Front Street West and Spadina Avenue in Toronto of a high-rise construction job gone wrong when a large window pane being hoisted by a crane begins swinging and spinning in the wind, eventually striking the building and raining shattered glass onto the street below. Apparently one person was treated for minor injuries, but amazingly nobody faked much more serious injuries like I would have hoping to cash in.

Keep going for the video, but skip to 1:15 for the juicy part.
