The 2010 Winter Olympics have opened in Vancouver. The Olympic flame was jointly lit by four Canadian sports heroes – all-time hockey great Wayne Gretzky, skier Nancy Greene, speed skater Katrina LeMay Doan, and basketball All-Star Steve Nash. The ceremony was held undercover for the first time and officially opened by Canada's Governor General Michaelle Jean. It was a stunning visual spectacular which started with a snowboarder jumping through the Olympic rings. More than 60,000 spectators witnessed 2,500 athletes from 82 nations parade, including debutants Cayman Islands, Colombia, Ghana, Pakistan and Peru. But the ceremony was overshadowed by the death of 21-year-old Georgian luger Nodar Kumaritashvili. He crashed at high speed at Whistler Sliding Centre during training just hours before the Games opened. The Georgian team, wearing black armbands, were given a standing ovation at the ceremony.
