Welcome back to the our channel for a feature about firefighters and aircraft all over the world that facilitate firefighting on land as well as the sea. Aerial dispersed fire retardant is not dropped directly onto the fire, it is dropped ahead of the fire line to make the fuel load less flammable. Water is dropped directly onto hot spots in the fire line to extinguish and cool the hot spots. The CL-415 is now built by Viking Aircraft of Calgary, Bombardier sold off the air division and now concentrates on recreational vehicles. Aircraft fire fighting is an expensive solution looking for a problem. like air ambulances, they are looking for ways to justify their existence.
