Full fire cover for the airfield would have been maintained. Stansted Airport Fire Service have one domestic pump appliance that is able to cover the airside and landside areas of the airport. This allows for rapid response when an incident like this occurs.
It is unlikely that the appliance would have returned to the station when local cover arrived, as the airport appliance crew would have been working on the active fire and the ‘watch manager’ of the airport crew would have needed to ensure the terminal and airport was safe from fire and could stand the incident down from their perspective.
