The Government Flying Service was established on 1 April 1993, when Hong Kong was under British rule. It then took over all the non-military operations of the Royal Hong Kong Auxiliary Air Force (RHKAAF), which was an auxiliary unit of the United Kingdom Royal Air Force. After Hong Kong was handed over to the People's Republic of China in 1997, the GFS remains as a government unit of the Hong Kong Special Administrative Region, and is responsible for search and rescue (SAR), air ambulance, firefighting, and police operations.
