Helicopter pilot Billy Yelberton crop dusts fields in north Talladega on Tuesday morning. The three-man crew works for Custom Air LLC based in Louisville, Mississippi, and travels seven months of the year spraying fields throughout the Southeast and Midwest. The advantages to crop dusting with a helicopter versus an airplane are many. The crew pulls the helicopter on a trailer with a truck and brings a fuel truck along with it. The crew drives directly into the field and within minutes is flying. When the helicopter needs to refuel or refill the sprayer tank, it simply lands on the pad atop the fuel truck parked in the field and refills and, in a couple of minutes, is back flying. An airplane would have to return to the airport. A helicopter, according to crew member Greg McDaniel, is also more precise spraying the fields.
