Five yellow lights hovering in formationMy girlfriend and I were driving home on Arkansas Highway 286 East last night. When we passed the church on Daugherty Hill Rd, she noticed a low-flying aircraft to our southeast. As I turned south, I noticed the aircraft come into my field of view. The road then turned east, and I saw it again to the south. It looked like five lights in a straight line. The lights were of a streetlight-yellow color, and appeared to be standing still, or matching our car's speed of 60 MPH.As the road turned south east to cross Palarm Creek, the UFO appeared to be hovering directly above the highway ahead of us, yet we could not year any loud engines or unusual noises. This is where I got the clearest viewing of the aircraft. The lights were very bright compared to the stars in the clear sky, and formed a flat line like a -dash-. As we approached them, they began to rotate in formation to the south, like a plane's roll, becoming vertically aligned before turning upside-down and disappearing behind the tree line.My girlfriend noticed it again to our south a minute later as we rode home.
