This is amateur video of a floor collapsing while hundreds of people were celebrating at this wedding banquet at the Versailles Wedding Hall in Jerusalem. It occurred on May 24, 2001. 23 people were killed and nearly 400 were injured. Engineers discovered that the collapse was due to a last minute design change on a portion of the structure that was not designed to carry a live heavy load such as the nearly 100 dancing people. The report is presented by MSNBC's Greg Jarrett and Chris Jansing.
