Hollister California- At CDF airbase planes re-fuel with salt based flame retardant.  Two Californa Fire Department Air Unit planes re-fuel their 1200 gallon tanks at the Hollister Airport about every 40 to 45 minutes throughout the day.  The sodium based fire retardant is used to contain fires to a specific vicinity allowing fire officials to fight fires from the sky as well as the ground.  Hollister California is home to two airplanes with 1200 drop tanks as well as an OV-1, "Eye in the sky" recently acquired from the military.  The OV-1 is an agile 750- horsepower military airplane that is used to, "Scope the entire fire situation" said Hollister firefighter Bart Wadell. The airplanes help fight fires throughout the central coast and inland areas. The planes are currently helping fight the lockheed fire in Santa Cruz.  August 14, 2009 Photo by Daniel Dreifuss
