Very Big Crane Failure

As a 400 ton roof section was being lifted into place by a 267 feet high crane at the Miller Park Stadium in Milwaukee in July 1999 the collapse of the crane was caught on a video camera. Three construction workers were killed.

The shock caused by the crane's collapse was severe enough to be measured on the nearby seismograph at the University of Wisconsin-Milwaukee.

The two loud reports about halfway through the video are the sound of bolts snapping as the crane is overloaded.
