Summary : At a drive-in during the summer my brother and I saw three lights above and to the right of the screen. The movie was "CAT BALOU." We observed them for approx. 20 minutes while one of them flew figure eights around the other two. Then one of the other lights would switch positions with the moving light and fly the same figure eight pattern. Suddenly two of the lights took off with great velocity and dissappeared. The other light stayed in its orginal position. Approx. 1 hr. later a light came speeding back and started circling the stationary light then took a position next to it and stopped. I am at home with my sick child today and watching the learning channel and heard a pilot report a similar sighting. I finally decided to go public
