Namibian teen athlete and their first woman Olympian medallist Christine Mboma was given a water cannon salute, songs, dance and a carnival street parade when she touched down from Tokyo. Water cannons showered the commercial jet that flew back home the 18-year-old at Hosea Kutako International airport in Windhoek, to celebrate the country's second ever Olympic medal since independence three decades ago. Mboma surged through a star-studded women's 200m field to claim silver in 21.81 seconds, a new under-20 world record, but her victory reopened debate about track and field's complex rules regarding women born with elevated testosterone.
