Worker walks along edge of the deflated roof of BC Place sports stadium in Vancouver

Worker walks along the edge of the BC Place sports stadium’s deflated roof in Vancouver, British Columbia January 12, 2007. The roof collapsed during a storm January 5 after an overzealous effort to keep the domed fabric roof inflated ended up helping it fail. The stadium is to be the site of the opening and closing ceremonies of the 2010 Winter Olympic Games. REUTERS/Andy Clark (CANADA)
