large football field size craft in Eluess Texas 1982

I was five or six years old at the time. A friend of mine and his dad were coming back from the Bellaire movie theater in Euless. during the drive home we saw a long line of cars on what seemed to be a back road that we were on. all of the cars were stopped as well as ours. Just to the left of us and all of the other cars was a huge oval shaped craft about the size of a football field. it was covered in lights and moving extremely slow. it looked to be a hundred feet off the ground. it was so long ago that i cannot remember what happened after that. I know there were alot of other cars there that were watching the same thing. Im twenty five years old now and have tried to find anything in the old news papers relating to the incident at that time. It happened during the time Tron was in theaters.Upon asking my friend about it years later he acted strange and avoided the question.
Date is approximate.  We would welcome other reports, or any newspaper articles, about the sighting.  PD
