A construction crane dropped a four-ton heating and air conditioning unit nearly 30 stories after a critical rigging strap holding the unit snapped. The unit reportedly crashed into the side of the building at 261 Madison Ave., N.Y., repeatedly, shattered windows and tore off metal and concrete as it fell to the street.
Luckily, the area had already been closed to pedestrian and car traffic due to construction working only 10 people were injured from glass and debris after the unit fell.
