A Thrush airplane, flown by Justin Farr, drops a mixture of water and foam in a demonstration for a presentation on the SEAT (Single Engine Air Tanker) program on Wednesday at the Farr Air hangar at North Weyburn. The program will provide planes like this to local fire departments to assist them on the ground in the event of a major fire, such as a grassland fire. Farr Air is one of seven companies around the province now certified by Transport Canada to provide this service in Saskatchewan.
