Driving out of Goldfield NV towards Tonopah NV noticed cars pulled over on side of road. 1st thought was that it looked like a VERY big bi-plane. They way the lights were. So we slowed to watch. Then i just disappeared. So we turned around and pulled over to see "wtf". Thats when 1 light reappeared. Then 1 light turned into 2 lights. Then 2 turned to three. It seemed to enlongate and grow. Then it just disappeared again. That was it.
