An aircrew aboard a Coast Guard C-130 Hercules aircraft fitted with an Airborne Dispersant Delivery System, sprays water during a training exercise 10 miles west of Anclote Key, Wednesday, Nov. 28, 2012. Dispersants are specially designed oil spill products that are composed of detergent-like low toxicity solvents. Dispersants break an oil slick into small particles that disperse into the water where they are further broken down by natural processes.
