Two unmarked, completely black helicopters flew directly over my head in single file, while I cutting the grass. They were approximately 200 feet or less above my head, moving in a northwesterly direction. There was a long spike on the front of the helicopter, perhaps ten feet in length, probably a gun of some type but I could not identify it. No lights were noted. I was unable to get a photo, unfortunately.((NUFORC Note: We spoke via telephone with the witness, and he affirmed that he did not witness what he felt might have been a genuine UFO. He stated that he submitted the report, principally because the flight formation and ground track of the helicopters was something he had never seen before. PD))
