The much-anticipated Olympic torch flame arrived at Hong Kong International Airport on Wednesday at 1.55pm - on a special flight from Vietnam. The plane's doors opened at 2.07pm, as Yang Shu'an, the executive vice-president of Games' organisers Bocog, emerged from the plane, holding the Olympic flame. Traditional Chinese music played and photographers began to record the long-awaited event. Yang was greeted by Gao Siren, director of China-Hong Kong Liaison Office, Tsang Tak-sing, Secretary for Home Affairs and Timothy Fok Tsun-ting, president of the Sports Federation and Olympic Committee of Hong Kong, local television reported. More than 200 primary school students, dressed in Chinese and Greek national costumes, and waving Chinese national flags, were waiting to greet the torch at Chek Lap Kok. Two primary school children - wearing Greek national costumes - then presented flowers to Yang. While Gao, Tsang and Fok looked on, Yang Shu'an carried the flame and waved to onlookers. He then walked down the red carpet on the airport runway slowly, to allow photographers time to snap pictures. Yang was flanked by Olympic Committee security staff, airport security staff and Hong Kong police. Yang and other officials then climbed into a special tour bus. Security is tight in the territory following some angry protests against the Olympic torch relays overseas. Pro-Tibetan activists have attempted to disrupt these events to express their anger at China's handling of recent unrest in Tibet. Hong Kong's torch relay is planned for Friday. The bus carrying the torch then left the airport and headed to the Hong Kong Cultural Centre in Tsim Sha Tsui. There, preparations are underway for a large celebration ceremony which will begin at 4.00pm. The plane carrying the torch had left Ho Chi Minh City in Vietnam on Wednesday morning. Local media reported there was a device inside the plane to help protect the flame. The arrival of the Olympic torch signifies the start of the 100-day countdown to the Beijing Olympics in August. Hong Kong is the first city in China to welcome the Olympic flame. It will also be hosting equestrian events during the Olympics This is the second time an Olympic flame has passed through the territory. The first was in 1964 as part of the Tokyo Olympics. The Olympic flame is a well-known emblem that symbolises the theft of fire from the god Zeus by Prometheus in ancient Greek myth. Later, a fire was kept burning during the ancient Olympics in Greece.
