Badminton is the fastest racket sport in the world, with the shuttlecock attaining speeds as high as 200 mph. The sport's origins may go back to the 5th century B.C., when a sport called Ti Jian Zi, shuttlecock kicking, was played in China. The modern version of the game can be traced to India in the 1800s, where it was played by British military officers, who then introduced the game to England upon their return home. A demonstration sport at the 1972 Olympics and an exhibition sport in 1988, badminton made its debut as an official Olympic event at Barcelona in 1992. Todays badminton racket, made of boron, fiberglass, carbon, graphite and ceramic, weighs a trim 3 ounces. The shuttlecock, made of cork wrapped in leather and goose feathers, weighs in at 2 ounces. The best players in the world come from Asia, where the sport enjoys enormous popularity. Olympic competition includes both mens and womens singles and doubles. The singles champions in the 1992 Olympics were two young Indonesians, Alan Budi Kushuma Wiratama and Susi Susanti Haditono, who in real life were engaged to be married at the time of their Gold Medal triumphs.
