A familiar image of a wildfire might be 50-foot flames with water-hauling helicopters circling a tower of black smoke. But for Helitack, the Washington Department of Natural Resources' helicopter firefighting team, the average assignment is much smaller. Helitack's goal is to keep fires under 10 acres. Last year, the team was 96 percent successful, said Dan Boyle, helicopter program coordinator. However, once a fire gets larger than 1,000 acres, it's essentially beyond Helitack's control.
