Professionals who make their living on the water usually do their jobs flawlessly, but accidents do happen, as seen in this clip from the Netherlands.
Two cranes on a barge shift and fall over while hoisting a section of bridge. Five buildings, including houses and shops, were crushed, and as many as 20 people were injured.
The heavy equipment was being used in the renovation of the Juliana Bridge over the Old Rhine River.
This video clip shows an aerial view of the destruction and how densely populated the area is.
The residents of 51 properties were been told they could not sleep at home on the night of the accident, according to the Dutch News agency.
