Two triangle craft observed over Harleyville.At around 0330 Thursday October 22nd, 2015, myself and a co-worker observed two triangle shaped craft over Harleyville, SC. Both craft were dark in color with red lights on the corners (non-flashing) and flew just above the tree line roughly 300 feet from our building. They were moving slowly at first coming back and forth across a heavily wooded area as if they were looking for something. They then hovered over the wooded area for about 5 minutes before accelerating very quickly upwards and then making an immediate 90° turn across the sky to the west and disappearing into the distance. Local police scanner revived multiple calls about the 2 craft over the area.
