Besides the regular Fire Department under the authority of the various city municipalities of Thailand, there is also the airport fire brigade, officially known as the AOT Rescue and Fire Fighting Department, which is run by the Airports of Thailand, a Government-owned Public Company. Its emergency-response personnel is trained in a special category of firefighting that deals with airport ground emergencies, but also conducts water salutes, i.e. the ceremonial spraying of an airplane as a tribute, e.g. prior to or after its maiden flight or after its retirement flight, i.e. the last flight before a plane retires from the skies.
