I had just started my night shift at the coal mine i work at.As i started out too the field,two large lights just appeared.These lights were side by side and then rotated then faded away.I stopped my truck to see if what was seen was'nt just a reflection coming from my dash lights.At first i thought it was an aircraft like those huge carriers that fly out of San Antonio's lackland air base.A Few minuts passed so i started to my destenation, keeping an eye out for something, when halfway there, the lights are back again, this time their spread apart much farther then the first time.The lights were seen for about 5sec.then one quickly faded out then the other followed there after.I was so excited and emotional at what was going on i wanted to call out to anyone on our two-way radio's who were in my area to look up in the sky to see what i was seeing.But i did'nt want to freak anyone out so remainded quit tell later.Again i sat and waited to see if the lights would reappear,and they did this time much farther apart then the secound time.They seemed to be miles from each other,they flicker on slowly stay on for several seconds and then flicker off again.This time another light appeared between the first two and even further than out.So i finaly got too my first peace of equipment,and i wanted to tell the operator if he saw anything since he was working in the directon of my sightings.I decided to tell the operator what i was seeing,as i described what i saw to him, he points and says "look there it is"one bright light just lit up for several seconds and again faded away.We waited about 5 min.and another bright light just flickerd on and then flickerd out.I remembered the time and date this event happened 2/16/2011@7;45pm it lasted about 30min.
