Pest Control

On Aug. 25, 1965, Mr. and Mrs. Robert Greenlee were sitting on their patio in Dunnellon, Fla., with a neighbor, Mrs. Riggs.

Mrs. Greenlee had just swatted a fly when a ball of lightning the size of a basketball appeared immediately in front of her. The ball was later described as being of a color and brightness comparable to the flash seen in arc welding, with a fuzzy appearance around the edges. Mrs. Riggs did not see the ball itself, but saw the flyswatter ‘edged in fire’ dropping on the floor. The movement of the ball to the floor was accompanied by a report ‘like a shotgun blast.’ The entire incident was over in seconds.

… The explosion was heard by a neighbor about 150 feet away, and it was subsequently learned that another neighbor’s electric range had been shorted out at the same time. There was no damage of any sort at the Greenlees, nor were there any marks on the patio floor where the flyswatter had fallen. With regard to the fly, Mrs. Riggs commented, ‘You sure got him that time.’
