Aboard Seanachai on August 22, we were on the Cooper River, passing under the Ravenel Bridge around 5 PM. Suddenly, we saw this small airplane making several close passes around the bridge and later, over Drum Island. At first I thought it must be a photographer, but it seemed incredible that the pilot would be making so many passes. We watched the plane, a Thrush S2R-T34, make big swooping curves around the iconic bridge, then drop down for a low pass over the trees. It was not until we were home again and some investigation revealed that the plane was likely spraying for mosquitos in the city and the island. (The photos clearly show the sprayer attachment.) Local news reports from a previous treatment noted drivers on the bridge were terrified at the sight of the plane. According to other reports, the low flying airplanes deliver specially modified chemicals to eliminate mosquitoes in areas of stagnate water. Although it’s the first time I saw it, this kind of delivery system has been used in this area for at least six years. This fighter plane was merely turning around over the river so as to continue making passes across the land–doing battle with the mosquitoes!
