Flicker lights seen in the night sky south of Big Sandy.

At around 8:44 P.M. as me and my girlfriend we noticed a strange light suspended in the night sky.  We stopped to observe it by the south end of town.  We obsevred the craft and seen that it was tear-drop shaped and that at the round bottom there were for lights one in front, one in back, and two on each side.  we had only seen the shape of the craft because of the lights on the craft.  The bottom of the craft where the lights were situated spun making the lights flicker.  This craft wasn't anything that we had both seen before.  We observed the lights in the same for about 20 minutes.  It then moved a little to the west and stayed in that place for about 5. In the last remaining minutes we seen the craft disappear.
