Abstract
The present invention entails a system and method of controlling and preventing the spread of land fires and particularly forest fires. This is accomplished by forming a substantial foam strip along an area spaced from the fire, and back burning from the foam strip towards the fire or fire area. To form the foam strip, the present invention discloses the method of dropping foam containing containers from an aircraft in a selected pattern along the strip area designated. The foam containers are provided with valves that open approximately on impact or at a selected time thereafter to cause the release of the foam.
