We were not sure if it was 1 large craft with 3 individually moving lights in a triangle formation or 3 individual crafts. But we were traveling south on hwy 15 towards Fairbury, Nebraska when off to the West side of the road we noticed lights in the sky moving erratically. My husband and two of my kids also witnessed this event. It was only there for about 1-2 minutes after we noticed it. I am not sure how high up they were or how large they were.
