Watching from the backyard facing south, witnessed what looked like a helicopter. Red and green lights flashing. Stopped and hovered for a moment or two, then proceeded north towards Cleveland, Ohio. Flew directly above me, saw what appeared to be cigar shaped vehicle. However, this seemed to have 2 white lights extending from the sides, like an airplane. With no visible attachments. No sounds of helicopter, or airplane, no sounds at all.Watched vehicle fly north, then turn right to a position and stayed there for hours. Just east of this position was a very very bright white light in the sky. Not a planet, not a star, but a large circular shaped light hovering in one spot. Just south east of this very bright light was another vehicle with the red and green lights flashing.Watched this from approximately 11pm till 3:15am.Turning to go back in the house, I saw another red green lighted vehicle come from the same direction as the first (from the south).This traveled north and was not able to view it when it was behind the trees.
