In 1960 the Division of Forestry decided to experiment with a small, skilled initial attack, or "helitack" crew to be transported by helicopter to increase the early arrival of manpower and equipment to an initial attack fire. Although the crews were trained for hover jumping and had purchased heli-jump suits from the US Forest Service, it was never found necessary to make a jump. Six helitack bases were established in the early 1970s. They were staffed with contracted Bell JetRangers. A typical Cal Fire helitack crew which responded with the helicopter consisted of one fire captain and two to three seasonal firefighters.
