 In past years residents of the state have reported on strange smoke rings that have been spotted at times. There are generally explanations for many of these cases. There is also an explanation for the large ring of smoke seen over Greensburg, PA on the evening of June 28, 2017. About 7:45 PM, a small aircraft was circling over the area, and emitted a black smoke trail that created the smoke ring. It was odd looking but there was an easy explanation.
